I had an old friend that was eccentric. He lived in a monolithic dome home made of fiberglass. He made his air conditioning from a 6” pvc pipe buried, to and under a running creek, exiting the other side. The distance was about 50 yards. He pulled the cooler air out with a small oscillating fan.
In NY state, there is a place called Howes Caverns...the owner built the hotel over a natural vent in the 1800s so the cool air exiting the caverns could cool the main dining room in his hotel...recognized as the first air conditioning in the US.
i think the explanation is backwards. Hot air rises and the higher the tower is the better the effect. the high tower would be an air exit and thus create a flow. Air intake should be lower and air is made to pass though the underground body of water.
I live here in the middle east and have stood on both ends of the wind catchers or what they refer to as barajeels. It's a much more strange phenomenon than simply catching the wind because when you're at the top of the barajeel, there is a massive heat gust that hits you which is hotter than the ambient temperatures. At the bottom, you'd swear there's some type of air conditioning because the air blows with great force through a slot as long as there's open ventilation at the bottom. I've also been inside the cooling tower as well (I'm electrical engineer and design building controllers and access to the electric trunking is often times put in the towers) So what I think is happening is as the air descends downward, it begins to cool and separate from the hot air which begins to rise. The higher the tower, the faster the air falls to the open lower pressure at the base where the slot opening is. It is this constant separation between the hot and cool air that keeps the flow of air moving. Because often times there is no wind at all in the desert but when you're at the slot opening, the gust of air is constant anyway. IT actually feels like you're standing in front of a strong air conditioner with cold air blowing on your face and the flow of air is really amazingly strong.
Hello Anthony, For this design to work does the lower floors of the house need to be sealed from the outside? I think that must be necessary otherwise the Bernoulli effect of wind blowing through the barajeels would draw air out from the tower and no air would circulate down to the living areas. It seems to me one would have ventilation coming in from the lower floors, but that is confusing me. Where am I missing the working concept of these designs? Thanks!
@@Snarge22 From where I was standing below the barajeels was an opening behind me that lead to the parking garage. As I entered into the hallway, there was a vent slit about 100mm wide and about 1.2M length which was below the barajeel but about ceiling height 3M and the force of the air was really astounding. I couldn't explain the effect of where this airflow was coming from. I asked one of the clients (engineer) if there was a fan from up above forcing this air down and he said no there wasn't. So I had the opportunity to go inside this ventshaft to work in the electric panel. I entered from the topside and lowered myself down. While at the top, the air flowing up was very hot but as I descended, the air became cooler and cooler until I reached close to the bottom (20M) where it felt like the air was actually being chilled. Well knowing physics and trying to conclude why this phenomenon was occuring, I reconciled the air must be splitting away from hot / cold air where colder air fell and hot air rose. The slit at the bottom was where the heavy air (cold) came through to the lower pressure area. This is as best as I can explain it.
@@magnusm4 I think they could. As the hot air rises, it could have the force to turn a generator and the cool air could act as a free air conditioning system. This same effect happens in mine shafts as well as early stories say the shaft air ports often times had forced wind come in making the mines very cold.
Thank you so much for this first person perspective on what the experience of these barajeels is like. It's one thing to see them online and hear the theory, but another to actually experience them.

My house was built 121 years ago, and it uses passive cooling. It is not as high tech as the Persians, but it helps. If it is 40¯C in the day, I open the windows upstairs and downstairs at night. The hot air is lighter, and draws the cool air in, cooling the thick brick walls, Close the windows in the day, and it is below 33¯C. I have not used A/C in years, even though summer is hot here.
@@HistoryWithKayleigh you said in the video the country your in doesn't have much ac? Where are you? I'm a new sub and don't know much about your channel yet
They found floor heating in an old house in sweden.. Something archeologists found.. Don't remember how old the house was sense i learned it in 3e grade or something.. Nothing new under the sun/moon
My house is 1818 in NY. The east wing is a large sun room used to trap the morning sun. Works very well. During summer opening the windows causes a cross breeze that keeps the house very cool. Old time people sure knew what they were doing.
Wind-catcher is just a small part of entire sum of the ancient air conditioning system. You could take time to study the architecture of colonial buildings here in Southeast Asia. Since we have very low wind speed and variable wind direction, our construction mainly use air wells and positioning of gallery/balcony with overhanging roof that keeps sunlight from touching the walls. Additionally the type and thickness of the wall also important. Thicker walls give a bigger heat-sink and the type that somewhat permeable allows it to "breathe" keeping the air cool from convection of air evaporation. We allow airspace above the roof with ventilation to promote airflow and every window have some kind of holes above it to promote airflow. Some old building like my grandfather's house have ceiling as high as 15 feet and airspace between rooms alike that of office cubicle. In my line of work this is the main problem of building construction here in Malaysia. We are now too dependent of air-conditioning and love of "modern" building design which is utterly impractical. Use of concrete ibs that is full concrete prevents water evaporation, no overhanging roof, none or impractical air wells, no air holes above the windows. I took practical students and showed them the danger of such housing. No stability of humidity level makes the room either too dry or too damp which the latter is much dangerous since it may lead to deadly spore infection of our lungs...especially the black ones that grows on damp spot. Shut the electricity and within the hour the house is no longer habitable in daytime...while at night it is too stuffy and hot without electrical ventilation. And I haven't start on the wildlife subject. Not sure about the middle east, but here in the tropics bad design may proof fatal. You could get cobra coming out of your toilet bowl, or rats infestations, or bird nests, monkeys hanging around, venomous insects and even bees making hives if the design accidentally makes it convenient for them to make it their home.
Nice info. I lived in Malaysia for 8 years and SE Asia for over 20. I spend a lot of time in Cambodia these days. Of all places that really need to rethink building practices, I'd say this ranks toward the top. I'd love to hear more of your thoughts about this. Is there a way I can contact you?
Hello fellow Malaysian! Yes, someone gets me! I rant about this issue and talk shit about developers all the time because of the problems you mentioned. I can't stand modern houses because our weather will never be suitable for it. I dream about kampung houses often especially when the weather gets too hot.
@@MrArthoz nice info, we have same problem here in Indonesia maybe more, like natural disasters that happened frequently, earthquake, volcanic eruption, etc. But it's beautiful place to live, can't blame the nature.
As a fellow Malaysian I have learnt valueble lessons from your comment. I agree, the developers here have been getting greedy these past 10 years which resulted in highly inflated housing prices. Even home buyers these days are brainwashed by fake advertising from developers.
Interesting and definitely one of many ancient technologies we should try to incorporate in modern buildings to help cut down energy usage/ cost in hot/ dry climates.
The wind catchers was not the sole methode to reduce the high temperature in old times. When you go to former Asyria and watch the ruins of their kings' palaces, you will notice their own method of keeping their residetial zone in moderate temperature. Their palaces were built very massive , with very thick walls , made of the mud bricks and covered from inside with the decorated slabs of alabaster. Due to thick walls the interior was holding the temeperature average between day and night and much lower, than temperature outside during the day time. When you go to LIbya, and visit Gadamesh (oasis 600 kilometer in the desert- where during the Roman times the Third Legion was located) ) - you will see, that locals have built all the old city as the one single building- 2-3 floors, the streets as the tunnels with the vertical shaft to the top- after each several meters -above the "street"-to assure some light there. The difference of the temperature inside vs outside is shocking. The peoples dressed for outside, can get cold after some time of visiting the place even in the summer. Stary
Besides thick walls and high cellings, the best method is evaporative. Most modern windows can be opened at the top, and bottom, as the hot air rises out the top, it draws cooler air in the lower open window. Add a frame 3 to 6 inches (90 to 180 cm) outside the window, stretch an old hemp potatoe sack on the frame, have the bottom of the sack in a bucket of water. The air movement evaporates the water cooling the ingoing air, cooling the room.
my apartment is in a 19th century building with thick sand stone walls of up to 70cm - and one part has almost 4m high sealing. Only... it has huge windows. Looks great but costs me a lot of heating in winter and the thermal mass works good but the huge windows heating it up in the summer. ^^ in Europe.
@@andefina5676 did I miss something or did you just mixed up cm and mm ;) 91.5 to 183cm is 3 to 6 foot but 3 to 6 inches would be roughly 7.5 cm ro 15 cm ^^ or am I just confused about the "()"
@@bobboscarato1313 I always try to convince my colleagues not to use those cheap 'cooling' devices because those will yes cool them but increase the humidity and it's already high in the summer here plus we do not have much AC ;) open the windows in the morning, keep the blinds down? when the sun goes up and hoping the thermal mass will get us over the two to three hot days in a row... ok that was 5-10y ago, now that method does not work anymore, excluding this and the last year the 5y before were in the top 8 of the hottest summers this 18xx here :( global warming is no joke
i can no longer find it, but there was a video of a man who was studying ancient Indian (India) technology. He showed how they were able to make ice, on a 90 degree f day. It was pretty simple, and he demonstrated with a bowl of water, taking it from warm to almost 32 f in mere moments. He even had ice forming on the surface of the water
I am starting to like some of these videos especially ancient architecture designs as that is something of hobby for me. A great example and probably in opinion one of the best ancient wind capture and cooling systems of the ancient world is the HAWA MAJAL of JAIPUR - it not only captures the wind to cool but has different size windows that affect the wind speed to speed up and slow down the wind which even during the hottest days can be kept cool inside there can be a difference of like 20 degrees difference from the outside its amazing to see and feel if you can go to India and visit the palace....
In areas that have 4 seasons and low water tables, using an underground air system is viable. Ground temp at 6-10 foot depths stay nearly constant around 55F. Using a simple solar powered fan and ductwork/tubes an air circulation system can be utilized year round to prevent freezing in winter and heat stroke in summers. Fine tuning may be needed depending on your region. Such as condensation catches in hot humid areas, pollen filters in higher allergen areas, etc but it is quite basic. Intake tube at least 2 foot above ground to at least 6 foot strait down. Elbow connect horizontal tubing at same depths for at least 20 foot to insure heating/cooling of the air finally elbow connect back to surface levels under or in your building. The smallest of fan will draw the air or even a high window opening would start circulation. Saw it on an off grid home builders show and have wanted one ever since. If you have ever had your water pipes freeze in the same year as it felt like 120F with the humidity you might also want one..lol.
Interesting and timely. I have land in the Chihuahuan Desert region of Texas and am in the process of designing an off-grid cabin for my semi-permanent residence out there. I'll look into making a form of this to help keep the place cool. Thanks for posting this!
look into "earth ships" and how they use free geothermal cooling, it's the same principle... the sun heats part of the building and starts a convection circuit and draws the air up and out and the cool air comes in from below where it is a constant 55F... then you just have to play with how much volume to cool your entire interior and then maybe think about mold and bugs and mice...
@Joe Duke Air conditioning, often abbreviated as A/C or AC, is the process of removing heat and controlling the humidity of air in an enclosed space to achieve a more comfortable interior environment by use of powered 'air conditioners' or a variety of other methods including passive cooling and ventilative cooling. It IS air conditioning. The means of cooling or is irrelevant to the actual means end.
My late grandfather's house had a 'windcatcher', as it's part of my country's traditional architecture. It cooled the house by about ~15C less than outside air. But one thing to note, the entire house design is completely different, the "backyard" is actually in the center of the home, with the building and its' rooms surrounding it, kinda like a big empty square with multiple storeys around it, there are a LOT of rooms that are all square or rectangular in shape. There are also wall openings in each room, 1 to let cool air in and 1 to let hot air out, creating a constant straight flow through the house. These had flaps that can be closed in cooler months. I do know the yard design has a lot to do with privacy, but I imagine the air flow control influenced it as well. Also the very thick walls that others have mentioned, ours were actually built out of crushed seashells and lime, it makes for very rough but very stable and cool to the touch walls. It's great for anybody living in hot desert climates, though in modern times with all the excessive amount of city pollution its very difficult to filter that out. I'm sure modern architects can come up with modern solutions for that though.
@@billymacktexasdetective5827 Your conversion is wrong. 90F is roughly 32C, and 31F is a touch below 0C. In another conversion (roughly) .... 100F = 38C 74F = 23C There's your 15C difference.
@@diomedes39 In order to cool a space, heat must be removed and rejected elsewhere. What is the source of cooler air that will allow for the transfer of heat from the space to outside? The wind that is at air temperature? So say it's 95F outside, how is a 95F wind able to cool the inside of the house to 68F??? 95F = 35C A 15C drop is 20C, which is 68F. If the outside air is 80F... 80F = 26.6C A 15C drop is 11.6C, which is 52F Do you buy a 80F wind cooling a house to 52F? Sorry, I don't, and you shouldn't either...
*I HAVE JUST DISCOVERED* that the soviet era apartment block I live in has this system... There have always been two vents that blow a very strong cold wind, I assumed it was coming UP by convection from the ground floor. But a quick test with a piece of paper shows it in fact coming DOWN from the top of the building. This explains the odd slightly funnel-shaped structures on the top of the building AND the greats in the floor outside that also blow cold air even on hot days... They are the "overflow" vents in case people have the doors closed to stop the system from pressurising... WOW - I would never have known but for your video.
18th century churches have open steeples that also act as wind catchers - but only if the person ringing the bell remembers to leave the door open until the end of worship.
Imagine a neighborhood or town full of houses with wind catchers and solar collection panels...that would be so nice. It seems like it would be expensive to build, at first, but after the techniques became commonplace and refined, perhaps less-so. Get on this, architects!
It would just depend on material needed to insure breathing. Like for example concrete wouldnt be good for it. Lighter more porous material would be better. This tech would be amazingly useful in the Western US which is primarily desert. California for example would benefit greatly with this technology, as it would help greatly reduce the need of A/C units. Tinkering with it to apply without needing to much water would have to be considered however, and of course resistance to earthquakes. With the current energy issues and the heat issues maybe it's time someone brings this up to the desert States.

Hi Kayleigh, it was very nice that you got interested in this subject. I am an architect and I had studied for my thesis, the great civilizations, Mediterranean Middle East, and in particular, qanats and air conditioning. As part of an economic development program in the 2000s, I presented various proposals for water retention, air conditioning, etc., in the Kirkuk region in Iraq. I had success, unfortunately the war arrived, and the project was not carried out. All architects should be interested in these different typologies of architecture around the world and adapt it according to the place. A big thank you for your presentation, I hope that many decision-makers will become aware of these construction techniques, it would do the greatest good for our small planet! Well done for your work, bacci.
Yes, I researched this a couple years back, Egypt & Ancient Persia both used this type of cooling ventilation, Iran's are possibly older. They both also invented taxation, Persian king Artaxerxes (pronounces Our taxes) is the father of modern taxation. Then we have glass windows.. Much older than realized & ice... Transporting& using ice, centuries before refrigeration was invented.
It’s becoming increasingly more and more apparent that older civilizations had technology that allowed them to tap into unlimited, free, clean energy as well. The modern day “controllers” are well aware of this and done everything they can to keep this information from the public.

Evaporative cooling. Great for dry regions, wont work in regions with high humidity. Houses were once built with double hung sashes. You raise the lower about half way, lower the top window half way. Cool air came in through the bottom forcing hot air though the top opened window.
How interesting. I live in the desert SW, in the U.S. We use evaporative cooling here. It's very effective with low humidity, but above 20% they don't work well at all. Thanks for posting this!
For some reason, this really peaked my interest in building and structural engineering. These designs are way eco-friendly, practical and sustainable. Not to mention they look aesthetically pleasing too.
Very interesting - timely reminder that you can do a lot without electricity! Once I drove from Nasiriyah to Baghdad in a car without air-condition in 50 degree C. I got myself a Keffiyeh (men´s headscarf), got it wet and took off with an open window. The cooling due to the water evaporation was so efficiently that my ears got numb and felt ice cold. Great video!
Imagine my surprise when I'm watching Bright Insight and hear him shout you out for a donation! You are an extremely interesting person, I'm looking forward to this one! They are very popular in the middle east and should be popular in the American southwest as well but unheard of out there.
Thank you! I do support my fellow creators when i can 🤗 I do love these windcatchers, they're fascinating and i don't understand why we don't have them in the western countries 🙂
Everything was destroyed in the southwest USA with very few temporary dwellings still hidden from the metropolitan areas. The wars of the 1800's were devastating to Turtle Island / America. Imagine extracting electricity from the atmosphere?
You will require hot air existing at a higher rate to create a vortex in the dwelling allowing cool air to fan the inhabitant/s. In my opinion it would appear that the taller tower would be for the hot air to rush out and the lower tower to pull in cool air. The constant rush of this vortex may produce condensation at the smaller and/or lower tower and in a more humid climate it should give you the opportunity to place plants that produce fruits and vegetables along with the added benefit of generating oxygen. It could also be a disaster if not well tuned periodically with the seasons. Do to the potential of this system incubating toxic molds that with time can lead to cognitive decline such as dementia which would eventually be diagnosed as Alzheimer's most engineering firms will not touch this advanced technology. Nevertheless this technology seems to be working well in these drier regions of our world making it worthwhile for other climates to experiment with in a distilled water extraction operation. Thank you
I live on the plains of west Texas. Where I live, the wind blows for most months out of the year. There are weeks where the wind never gets below 20 mph. We also experience haboobs a few times a year. A windy day here consist of sustained 40+ mph winds. We have one of the best wind research facilities in the world. Yet it baffles be that we have yet to implement technology like this. We still don't use wind turbines out side commercial use. The sun shine a majority of the year, and solar is barley making a a foothold in town. It doesn't help that the electric company makes customers jump through hoops to install solar. This is wonderful tech. I wish more people knew about it.
wind catchers were very common. almost a 100 years ago my city of hyderabad in pakistan was known as city of wind catchers. but alas same is not feasible now due to high usage of air conditioner causing air to further warm up.
In Italy the ancient Etruscans buried their dead in surface tombs, one of which might be the Cucumilla. The Cucumilla is most unusual as it has two center towers, one square and one round. Perhaps it incorporated a function known previously. IF the Greek Dark Ages was caused by intense light AND HEAT, the design inside the Cucumilla could have been how a large meeting area was cooled.
In all deserts, it gets cold at night. Building a giant tomb to keep the cold air of the night is impressive in scope. Besides the fact that most deserts are on cemented sea beds or bed rock making it very difficult to dig into. This isnt really refrigeration though they arent making any cold. They are just saving cold.

as a HVAC-R tech this is interesting but i would like to see numbers to see how well it works in certain conditions. this is already being done it is called free cooling with a economizer. if outdoor air temp is lower then inside temp then draw fresh air in. using the stack effect and evaporative cooling is a neat idea but this will only work in arid environments with low humidity.
Evaporative cooling is state of the art. Highly efficient, problem is legionella or other bacterias and fungi very strict rules apply for supply air conditioning. In my experience you can get 6°C colder supply air by spraying it with sufficient room temperature water (going from 30 to 95%hum). However, the system looses the evaporated water so it is not useful in deserts. There I'd recomend a conventional heatpump. As the humidity is usually undesirable indirect cooling (of another medium using exhaust air) is common. Now regarding freecooling vs this passive wind channeling: The numbers compared to freecooling are easy: You save the fans. So E_saved ~ v_air^3 ~ mdot_air^3.
@@MaxMustermann-bm7qt Another idea you gave me is putting a 1000 liter water tank (1m^3 or 250 gallon) in your home and connect it to some fans to stabilize the temperature in the summer.
@@sybrandwoudstra9236 works, but makes the rooms more moist. That is the same effect that air humidifiers use for cooling. Wet cloth and a fan also do the trick.
As amazing as this is, especially for it's time, it is still only usable in low humidity areas. In a high humidity environment it is useless, in fact it would compound the heat by adding humidity to the building...still there are many areas of the earth, even in the United States, that could greatly benefit from this ancient technology.

Older buildings in the American South have high ceilings and a window above each door that can be opened to allow heat to escape by convection. In more recent times, a whole-house attic fan can ventilate a house when the windows to the outside are opened, sucking the air through the house and then out the attic vents. It really works well in spring and autumn, and also helps air the house out. Swamp coolers are something to consider, too, maybe with some modern updates, but they don't work very well in the humid South. They are better for some of the more western and mid western states. Some combination of these with ever-increasingly efficient air conditioning systems or heat pumps can really decrease the demand for electricity.
Heat pumps in cooling mode are exactly the same as domestic air conditioners. They're no more efficient at cooling. In heating mode they're quite efficient until they hit low temperatures but in cost terms they still work out to be more expensive to run than gas boilers in climates that have cold winters.
@@HistoryWithKayleigh It's called HVAC. It looks like intellectuals are determined to take us back to the dark ages. Fortunately you all will FAIL. Witness what is going on in Europe right now with heating.
I'm contemplating retrofitting my ranch style house with a passive cooling tower. A few trenches, some cleverly laid pipe, a tower tall enough to draw...it may work.
This reminds me a great deal of the passive solar heating and Earth cooling principles in earthship construction. Basically, sun facing glazing which is angled enough to minimize solar gain in hot seasons, and maximize it in the cold, while large pipes run under the backside of the bermed house, away from the sun. These pipes are deep enough to cool air that passes through them. The sun heats the front of the house the most, and when the pipes are opened in combination with front windows/skylights, convection draws cool air through this house.
this is it... I've never felt how cold they get, but I've watched the videos about "earth ships" and the free geothermal cooling they use, and it seems very simple, easy, and not very complicated...
@@VenturaIT well of course it's complicated, for one, cooling air dehumidifies it, meaning moisture in the pipes, meaning you need to take steps to avoid mold. That's only one thing, too. Making these windcatchers was surely very complex, too.

Even dealing with mold it's not complex as done successfully in the "earth ships."
@@VenturaIT Yeah, not saying it's impossible, and the solutions are already thought through, tested in certain environments too. Was just saying it wasn't as simple as putting pipes in the dirt.
You could use these wind air conditioners as wind electricity as well. Using a series of smaller propellers within the protection of the tunnel would allow easy access for repairs and would protect from environmental hazards. It would remove individual homes from a grid system that ultimately fails in extreme situations. It would be easy to maintain and fix, and certainly cheaper. It would be perfect as well for those areas that have extreme weather. The whole debacle in Texas last winter could have been completely avoided. Once again, ancient technology teaches us we don’t know as much as we think we do. Thank you!
Please excuse me, I’m not being nasty but as someone within the industry I can say this won’t work and is impractical. These small props running small dynamos would barely make a single small light glow. You may get a small trickle charge into a battery. That’s all. In this town solar would work much better as there would be few clouds. As far as Texas is concerned, the problem was cold not heat. First the dynos still would have frozen, second you would have air below zero being blown down the ducting freezing the house so you would need to close off the airflow stopping the dynos. Heating takes a lot of power so they wouldn’t be sufficient. Again great idea, keep it up but in this case wouldn’t work. Sorry
Texas’s problem is they didn’t spend the money to winterize their grid….. blame your state government for not doing the basics of governing. While extreme cold snaps are rare in Texas, they aren’t unheard of and this should’ve been protected against and could have been protected against, they chose not to because they didn’t want to spend the money and didn’t care what happened to people in an extreme winter weather event. I don’t live too far from Texas and in my community our electric grid was winterized, we experience the extreme cold a little bit more than Texas but not much. My state is a small rural state too, and we could afford it, Texas has no excuse. The only thing we had problems with in my state when that happened was the gas companies, and that was more because of their greed than a problem of our infrastructure.
A windmill generally requires 20-25 mph min. to produce minimal power. Even where I live wind frequently blows and people assume it would work but a look at average local wind speeds online shows 9-10 mph. not even close or I'd have several up.
Factories always had tall Smoke Stacks to provide better draft for the Boiler Room. Wind Catchers pull air Up and out of the building. The lower tower might bring in the cooler air. Hot air wants to rise so the taller tower will create the draft.
When I was attending Michigan Tech and growing up travelling to the UP I was always fascinated by the old smelter towers and how much wind was at the base. Felt really cool too on hotter days. I've had thoughts over the years developing a structure around one to preserve and utilize the differential capabilities.
@@jafinch78 Constant wind makes it feel cool even if air is hot, a combination of thermal mass and wind tunnel effect can be combined ,making life bearable .
@@obiecanobie919 I recall they also have a sun screen design also that helps keep the building cool now that I think about. Something like shades and still lets air flow. Some sort of honeycomb or repeating design. I forget if at night they open up the building also to heat exchange to remove more heat from the structure which definitely is made from a large thermal mass... even if sunk in the ground will warm up during the day and can be cooled off at night.
Would a wind catcher system work in a place like Louisiana or somewhere it’s like 100 degrees and 80 percent humidity? I’m amazed at the ingenuity of people from all over the world and throughout time! Thank you for covering this!
Too cool, Ms. Kayleigh! heh, heh Interestingly enough, I just watched a video about wind catchers recently . Honestly, you explained the mechanics much better. The other video didn't mention the partitions inside the towers. To be fair, I think the video was more for the aesthetics of design and eco-friendly a/c alternatives than the mechanics involved. If you've ever felt a 2-4 degree drop in temperature, you get an idea of how effective these are. Overall, I have to say, our forbears were some pretty smart folks. Scritches to the kitties!✌🏻🐱
I have seen an interesting design inside a passive solar home. It's a heat exchanger, using a "rock bin" which is a room full of small rocks. Hot air is collected at the top of the home, drawn into a vent that goes to the rock bin in the basement, cools as it flows down through the rocks and is distributed from the bottom of the rock bin.
That's super cool. I can see the benefit in dry desert climates for sure. I do wonder how this works in places with tropical storms though. Would you get a lot of rain in the structure. Places like Central America, South America, South-East Asia for instance where stormy hurricanes and monsune are a yearly event if not more frequent.
I'm a 15 yr hvac professional. The principal is similar to how a whole house fan works. It cuts down the heat load. Most of the heat is in the attic and the whole home holds heat like a sponge. If you pull in cold air it pushes the hot air out. Knowing wind direction. Proper placement of windows and well.built structures will passively cool. However some buildings will always need hvac. Especially in certain locations
@@pauledge1621 Or if the area you live in is covered in trees and the wind does not reach the ground. This would work in a flat arid climate. My grand parents lived in Oklahoma and the wind blew constantly there. Here in southern Alabama it is often still and humid.
I grew up in Hawaii in army housing without air conditioning. Many people had a window unit or two but you really didn't need one because the homes were built to allow great air circulation. In fact, one entire hallway in my house going back from the kitchen to the laundry room was all screen. We had very long overhanging roof lines that kept rain out and precluded the need for rain gutters. The biggest problem with cooling a house is moving/circulating the air often enough before it has a chance to build up all that trapped heat from the sun.
Interesting n informative thanks South Indian Hindu Temples r built to keep the interiors cool airy at the same time with enough natural light similar vents r built for light n hot air exits. Row houses have this type of wind catchers n hot air vents. more research required in this to reduce Global warming EL NINO. etc
That was super interesting. It's definitely dependent on where you live (what can be done to combat heat and cold). Where I am we have mostly dry winters, no snow here, very little rain, very very little clouds, wet summers, mild to extreme humidity, lots of thunder storms. So, my solutions: 1) in winter: if there is sun (and outside is warmer than inside), open doors/windows until just before sunset/until the air starts cooling, then close everything up, to keep the heat in. 2) in summer: when (if) it gets cooler in the afternoon, open doors/windows until you go to bed. Keep them closed during the day. It's considerably cooler, as long as humidity and heat have not persisted for days, if heat has persisted I find it more effective to have a fan blowing air out of a room, on the sun-facing side of the house (bonus if you have a fan to blow air in from the non-sun-facing side, or into the house from a cooler room). Using my thermometer I have noticed that even though a winter wind feels colder (because of evaporation off of your skin) the actual temperature is most often warmer than the inside of your house, so on warmer winter days I set up my fan to bring warm air into the house through a window on the sun-facing side. I thought this would be easy to explain. lol. This may or (probably) may not apply to you :P
I can’t believe I’ve never heard of these fascinating ancient inventions! I’d very much enjoy seeing a more in-depth look at wind-catcher types and functionality. ✨👍🏽Very cool.
@@HistoryWithKayleigh Good morning Kayleigh. The mark of the beast will be IN the right hand or IN the forehead. It is spiritual and physical. Most of the world worships the beast by keeping sunday, friday, Christmas, Easter, Eid, Diwali, etc. There is something physical coming that people will have to take if they want to buy or sell. Muslims go to the mosque on fridays. Our Lord Jesus never ate shrimps or pork. Prayerfully read Leviticus 11:43 and Revelation 21:8. If you make yourself abominable, that is a sin! Repent. Happy new year! The new covenant will not save you if you continue being rebellious and stubborn against the word of the Lord. It is a sin to steal and a sin to forget the sabbath (saturday). *1 Samuel **15:23** KJV - For rebellion is as the sin of witchcraft, and stubbornness is as iniquity and idolatry. Because thou hast rejected the word of the LORD, he hath also rejected thee from being king.* Witchcraft, sorcery idolatry, witches, sorcerers, idolaters will be cast into hellfire. Only they that are washed in the blood of the Lord Jesus and keep his commandments shall be kings and priests. There is no such thing as a sunday rest or sunday sabbath in the Bible. Only the seventh day is blessed, sanctified and hallowed. Isaiah 66:22,23 says that from one new moon to another and from one sabbath to another shall all flesh worship before the Lord in the new earth. Matthew 7:21-23 proves that not everyone that says Jesus is Lord will enter the kingdom. We need to do the will of the Father which is to obey and honor our Lord Jesus Christ. He kept the sabbath, new moons and holy days while he walked the earth. Why do you keep sunday, Christmas, Easter and January 1st which he never kept? Repent.
This is Amazing.. Actually This is How I found out All about yr program's. A sweet voice that draws the history into a New life in One's mind's. Thank you 💕
Great video and highlights of some historically significant passive cooling design strategies. I'm a mechanical engineer who has included a few of these in my own building systems design, but their practice is uncommon and I'd guess that most architects and engineers in the USA have never included any of these strategies in their designs. Modern A/C makes it too easy to just throw in some A/C and be done with the problem quickly and easily. One local architect that stands our for using wind and adiabatic towers in multiple projects is EHDD in San Francisco, CA; The Carnegie Center for Global Ecology and the Zion Canyon Visitor Center are two project examples that come to mind.
subjects "down to earth" like this need to be addressed ! It feels great to dive away from megaliths blocks and civilization collapses sometimes x) and remind us we're closer than all the simple people than we often think about ;)
When it's hot and humid instead of using the air conditioner I open the east window with my 22" fan blowing out then I open one window on the shady north side of the far west bedroom. This pulls shaded air through the house and keeps things bearable(not comfortable) in July and August. I also use three smaller fans as needed but even all fans on high speed costs less than air con,like maybe 1/4 the cost. That's all money I can save for winter heating which can be a long season here. Not as economical as a good passive cooling system but it does ok for now. I have done this for twenty years here but when I grow elderly it might not be enough.
**ventilation! Air conditioning by definition has to dehumidify and actively chill the air :p This wind catcher method of ventilation is so clever, I definitely wish it was more common! Even in places where air conditioning is necessary, it would help the efficiency of the a/c by cooling the building more effectively at night!
Since I first got into greenhouses, I have firmly believed the technologies behind this video (and the ice house). Now, 30 years later, I finally have the time and resources to do some of them and just at that time, I find you with the histories that were missing from my limited knowledge. I'm going to enjoy this ride! Thanks for the videos!
I just discovered your channel and after reading your "About" page I must say you're a very funny person. The concept of wind catchers is pretty cool. It would be awesome if it caught on here in the American South, well all over really. Designing them around hurricanes and bugs would be a challenge though. I'm looking forward to watching more of your content.
Thanks Kayleigh. Fascinating. Clever passive engineering technology which means it's low cost. The problem though we have in the Wild West -- that's where the smoke is coming from on the satellite photos -- is that when it is really hot it is because the wind has stopped. The good news in those moments -- the utility industry has called this the Hundred Hottest Hours problem, for which the grid is overbuilt to meet demand when the sun is out and all the AC units go on -- is that The Sun is Out. Using low cost parabolic troughs with mirrors or aluminum we can produce steam at a cost roughly competitive with Natural Gas at $1 per mBtu (and it's around $4.50 now in USA -- Europeans are being gouged at 12.50 now). In other words, at that price, it is gravity and will start to matter, at scale. Hook the steam or hot water from the trough to a low cost chiller and voila, AC. I reckon it is the lowest cost solution to the utilities' biggest problem. Furthermore, with these troughs we can desalinate seawater -- it's a still. The boiled water that evaporates and re-condenses has no salt in it. The trick is to get the salt back to sea safely, not on the shore which will kill everything. Drones anyone? A rant for another occasion. Aerial or submerged. I appreciate your tutorial and the Persian architecture is something we should all admire and emulate where suitable. Did I mention that Wind is The Air Apparent? It can replace all nuclear power stations in a few decades at a much lower cost without any risk to human life. The birds will figure it out especially when you paint every other blade. The renewable wars are over and we've won; it will just take time for the orchard to bloom in full. From then on we can live off our income (sun, wind and rain) forever. What's not to like?
Solar stations create micro climates and can kill entire flocks of migrating birds. They're a great option, but only efficient enough when using salt as a medium. If the objective is desalination, sure use water; energy is the bonus in that case, not the objective. Wind power is great, but not without massive downsides. It cannot be located in populated areas due to the psychological effect the chopping noise and light disruption. They require massive areas of land, IE disruption of wild spaces or farms. The effects on wildlife, including migrating birds and land animals are severe. They create catastrophic deadzones where wildlife cannot inhabit for the same reason they can't be placed in towns and cities. Just painting a blade doesn't solve diddly. Birds can see the blades just fine, better than we can. They're taking the risk that they can get through and failing. Dumping salt back into the sea is painfully stupid. Sure, eventually it will disperse, but it will increase the salinity of the local area wiping out all sea life. Furthermore it's a valuable commodity, no reason to waste it when it can be used. Even if it were to be a waste product, dumping it in salt pans would be the best solution. Nuclear power is the least damaging, least wasteful, most power producing of any of the above options even taking into account the catastrophic risks. It won't solve all our problems, but it must be part of the solution. I'd rather live in Pripyat than in LA because the air is literally safer to breath. Hell, the air in Utah(where I live) naturally has more radioactivity than the Chernobyl exclusion zone simply because of the uranium in the rocks and dust. I'm not discounting the dangers of nuclear power, but I'm also not an animal shitting itself at a hearth fire because I can't understand how to use it safely. The "renewable war" is a marketing scam to sell government officials snake oil and sell the public on politicians willing to do something new and exciting instead of using proven solutions we have known about for over a century. Even fossil fuels have their place. The reality is that we need all power generation options or we are screwed. We also need to recognize that there is always a cost, there is no free power and no free resources. The reality is that as a species we need to think long term, in terms of generations rather than decades or petty election cycles. We need to stop looking for easy ways out of our problems, we cannot afford that cost anymore.
@@OspreyKnight Big solar isn't the way forward. PV is infinitely scalable and virtually free, being made from sand and collecting free energy from the one fusion reactor with the engineering worked out and perfectly sited, far, far from here. Nuclear energy is the only power source that the market will neither invest in nor insure. For a reason -- Too expensive / Too risky / Too late. Even the Japanese can't keep them safe and it's a technology that does not allow for errors. Read Rylands v Fletcher in re strict liability. (English High Court 1868). Game over.

@@henryhewitt1571 Welcome to the internet. You are a product of radicalization, not rational thought and knowledge. Its not a competition. If it's a competition, drill for oil, its the cheapest energy source available. We can burn this planet to the ground until we finally decide it's too uncomfortable to live here and leave. "Even the Japanese" that's racist. Nor is the nation of Japan the best at environmental issues. You're totally right. The market for nuclear power is completely poisoned by ignorant fucks who would serve humanity better as fertilizer. "Read Rylands v Fletcher in re strict liability. (English High Court 1868)" Jesus Christ.... ""the person who for his own purposes brings on his lands and collects and keeps there anything likely to do mischief if it escapes, must keep it in at his peril, and, if he does not do so, is prima facie answerable for all the damage which is the natural consequence of its escape" "Many courts in the United States have attempted to use Rylands to justify absolute liability, which it was never intended to do; while absolute liability is where no defense is applicable, in Rylands itself Lord Cairns accepted that there were some situations where the case should not be applied" If that applied to power generation there would be no coal, natural gas, or wind power. All of them on a big enough scale cause damage outside of their property. Even Solar has environmental issues that extend past property. It would also be damned impossible for nuclear power, the most highly regulated form of power generation requiring its own energy commission, to have all blame for a disaster lain on the private company running the power plant. Thus totally invalidating the Rylands argument. TLDR, if something goes wrong at the plant, the government is ALSO going to be at fault. No other method of power generation on a national scale can beat nuclear power in terms of safety. The reactors available now absolutely cannot cause widespread damage. It is physically impossible for them to do so. It would be legally impossible to build those other types in the US because of their potential risks. The waste products are almost comically easy to dispose of if it weren't for the morons mentioned above. A lie unchallenged is tomorrow's dogma. I won't leave your BS unchallenged, because its already well entrenched dogma fueled by ignorance and stupidity.
The drawback of AC is that multiple units blow hot air around a city and when concentrated together in a smaller area, they create heat islands which raise the external urban temps.
I’m Iranian, a lot of things were invented in Iran ( great Persia) which most people not aware of it and because of bad regime in Iran , western people think we are uncivilized people. I hope we people of Iran get rid of evil regime in Iran and gain our respect from world again.
Much respect to the middle eastern nations for their innovation in architecture, and especially medicine. While Europe was practicing medical superstition, the ancients of Persia had reliable, learned physicians who understood physiology and could actually heal people.

Why did the indigenous people in Latin America store water in clay pots ... and especially certain types of clay? Because it was a semi-permeable mud, then the vessel "sweated" and that cooled the water by evaporation.
I'm in Yuma....these could work except during the monsoon season..I think.. It's definitely interesting and I'm curious as to why we don't use them here. Now in the past we used to use water assisted air conditioners with water towers in the backyards (tall with wooden slats) and water would run down them cooling the air and pumped into the home but as I said that was a thing of the past.
When you think of the engineering involved to build these, and my guess, the trial & error to get the technology correct, it’s just amazing. If you put in perspective building pyramids and moving 200 ton megalithic rocks and getting to fit like a jigsaw puzzle, re-directing air was probably child’s play. For someone like me that tries to predict lightning in a 2 1/2 mile radius, my day is filled with atmospheric static electricity and negative and positive energy imbalance. I have the benefit of a sensor that’s checking the precursors of a lightning strike 50 times a minute, a computer and an algorithm doing all the calculations. How these people (all over the world) did what they did is just incredible.
@@HistoryWithKayleigh what I was led to believe, at least in Egypt, people would sleep on their roofs to escape the heat. I just took “roof sleeping” as fact. It wasn’t till yesterday thinking about that theory and wondered as tightly packed as some of these houses were, what if one of your family members or neighbors snored? Maybe worse, what do you do if one of your younger neighbors missed out on the “decorum gene” and had no issues with public displays of affection? I’m thinking the redirection of wind would be best for everyone. Including young children…
These are a more simplified version of the swamp coolers used in the south western part of the United States. Although the swamp cooler uses a "grass" filter, constantly flushed with water to provide evaporative cooling. Along with electric fans to move the air. While this is ingenious ancient tec, im just pointing out that modern man has,somewhat, adapted it. In no way diminishing this incredible achievement.
damn as a mechanical engineer i would really like to work on a design to retrofit current homes with something like this. if only i was back in school! this would make such a great thesis.
While looking for a house years ago we went through a house built in the 1910s that had a pump from a sand point well discharging into a huge radiator about 10 feet wide and 6 feet high at a 45 ° angle that shared the gravity flow coal heater and cooled the house. The catch basin was pumped back down another well returning the water underground. Kansas.

I had an old friend that was eccentric. He lived in a monolithic dome home made of fiberglass. He made his air conditioning from a 6” pvc pipe buried, to and under a running creek, exiting the other side. The distance was about 50 yards. He pulled the cooler air out with a small oscillating fan.
I would say he was very creative.
"earth ships" are doing the free geothermal air conditioning today... it's not very difficult or complex
In NY state, there is a place called Howes Caverns...the owner built the hotel over a natural vent in the 1800s so the cool air exiting the caverns could cool the main dining room in his hotel...recognized as the first air conditioning in the US.

I remember read about it year ago on summer.
but during winter it seems no one read about A\C.
i think the explanation is backwards. Hot air rises and the higher the tower is the better the effect. the high tower would be an air exit and thus create a flow. Air intake should be lower and air is made to pass though the underground body of water.
We have this system in morocco and al Andalus
That's awesome!!

Hey I know a simpler version of a wind catcher.. A window..
As the world warms and becomes more developed, we use more air conditioning and energy which in turn heats the earth more.
Might be forced to get ac because of permits and all that jazz. The fact that you can't put a meter on this technology might be an issue too.
I live here in the middle east and have stood on both ends of the wind catchers or what they refer to as barajeels. It's a much more strange phenomenon than simply catching the wind because when you're at the top of the barajeel, there is a massive heat gust that hits you which is hotter than the ambient temperatures. At the bottom, you'd swear there's some type of air conditioning because the air blows with great force through a slot as long as there's open ventilation at the bottom. I've also been inside the cooling tower as well (I'm electrical engineer and design building controllers and access to the electric trunking is often times put in the towers) So what I think is happening is as the air descends downward, it begins to cool and separate from the hot air which begins to rise. The higher the tower, the faster the air falls to the open lower pressure at the base where the slot opening is. It is this constant separation between the hot and cool air that keeps the flow of air moving. Because often times there is no wind at all in the desert but when you're at the slot opening, the gust of air is constant anyway. IT actually feels like you're standing in front of a strong air conditioner with cold air blowing on your face and the flow of air is really amazingly strong.
Hello Anthony,
For this design to work does the lower floors of the house need to be sealed from the outside? I think that must be necessary otherwise the Bernoulli effect of wind blowing through the barajeels would draw air out from the tower and no air would circulate down to the living areas. It seems to me one would have ventilation coming in from the lower floors, but that is confusing me.
Where am I missing the working concept of these designs?
Thanks!
@@Snarge22 From where I was standing below the barajeels was an opening behind me that lead to the parking garage. As I entered into the hallway, there was a vent slit about 100mm wide and about 1.2M length which was below the barajeel but about ceiling height 3M and the force of the air was really astounding. I couldn't explain the effect of where this airflow was coming from. I asked one of the clients (engineer) if there was a fan from up above forcing this air down and he said no there wasn't. So I had the opportunity to go inside this ventshaft to work in the electric panel. I entered from the topside and lowered myself down. While at the top, the air flowing up was very hot but as I descended, the air became cooler and cooler until I reached close to the bottom (20M) where it felt like the air was actually being chilled.
Well knowing physics and trying to conclude why this phenomenon was occuring, I reconciled the air must be splitting away from hot / cold air where colder air fell and hot air rose. The slit at the bottom was where the heavy air (cold) came through to the lower pressure area. This is as best as I can explain it.
I wonder if with modern development, we could harness both the cold and hot winds.
@@magnusm4 I think they could. As the hot air rises, it could have the force to turn a generator and the cool air could act as a free air conditioning system. This same effect happens in mine shafts as well as early stories say the shaft air ports often times had forced wind come in making the mines very cold.
Thank you so much for this first person perspective on what the experience of these barajeels is like. It's one thing to see them online and hear the theory, but another to actually experience them.

They found floor heating in an old house in sweden.. Something archeologists found.. Don't remember how old the house was sense i learned it in 3e grade or something.. Nothing new under the sun/moon
My house is 1818 in NY. The east wing is a large sun room used to trap the morning sun. Works very well.
During summer opening the windows causes a cross breeze that keeps the house very cool.
Old time people sure knew what they were doing.
Wind-catcher is just a small part of entire sum of the ancient air conditioning system. You could take time to study the architecture of colonial buildings here in Southeast Asia. Since we have very low wind speed and variable wind direction, our construction mainly use air wells and positioning of gallery/balcony with overhanging roof that keeps sunlight from touching the walls. Additionally the type and thickness of the wall also important. Thicker walls give a bigger heat-sink and the type that somewhat permeable allows it to "breathe" keeping the air cool from convection of air evaporation. We allow airspace above the roof with ventilation to promote airflow and every window have some kind of holes above it to promote airflow. Some old building like my grandfather's house have ceiling as high as 15 feet and airspace between rooms alike that of office cubicle.
In my line of work this is the main problem of building construction here in Malaysia. We are now too dependent of air-conditioning and love of "modern" building design which is utterly impractical. Use of concrete ibs that is full concrete prevents water evaporation, no overhanging roof, none or impractical air wells, no air holes above the windows. I took practical students and showed them the danger of such housing. No stability of humidity level makes the room either too dry or too damp which the latter is much dangerous since it may lead to deadly spore infection of our lungs...especially the black ones that grows on damp spot. Shut the electricity and within the hour the house is no longer habitable in daytime...while at night it is too stuffy and hot without electrical ventilation.
And I haven't start on the wildlife subject. Not sure about the middle east, but here in the tropics bad design may proof fatal. You could get cobra coming out of your toilet bowl, or rats infestations, or bird nests, monkeys hanging around, venomous insects and even bees making hives if the design accidentally makes it convenient for them to make it their home.
Nice info. I lived in Malaysia for 8 years and SE Asia for over 20. I spend a lot of time in Cambodia these days. Of all places that really need to rethink building practices, I'd say this ranks toward the top. I'd love to hear more of your thoughts about this. Is there a way I can contact you?

@@CHMichael THAT is a GREAT idea!
The wind catchers was not the sole methode to reduce the high temperature in old times. When you go to former Asyria and watch the ruins of their kings' palaces, you will notice their own method of keeping their residetial zone in moderate temperature. Their palaces were built very massive , with very thick walls , made of the mud bricks and covered from inside with the decorated slabs of alabaster. Due to thick walls the interior was holding the temeperature average between day and night and much lower, than temperature outside during the day time. When you go to LIbya, and visit Gadamesh (oasis 600 kilometer in the desert- where during the Roman times the Third Legion was located) ) - you will see, that locals have built all the old city as the one single building- 2-3 floors, the streets as the tunnels with the vertical shaft to the top- after each several meters -above the "street"-to assure some light there. The difference of the temperature inside vs outside is shocking. The peoples dressed for outside, can get cold after some time of visiting the place even in the summer.

Besides thick walls and high cellings, the best method is evaporative. Most modern windows can be opened at the top, and bottom, as the hot air rises out the top, it draws cooler air in the lower open window. Add a frame 3 to 6 inches (90 to 180 cm) outside the window, stretch an old hemp potatoe sack on the frame, have the bottom of the sack in a bucket of water. The air movement evaporates the water cooling the ingoing air, cooling the room.

@@bobboscarato1313 I always try to convince my colleagues not to use those cheap 'cooling' devices because those will yes cool them but increase the humidity and it's already high in the summer here plus we do not have much AC ;) open the windows in the morning, keep the blinds down? when the sun goes up and hoping the thermal mass will get us over the two to three hot days in a row... ok that was 5-10y ago, now that method does not work anymore, excluding this and the last year the 5y before were in the top 8 of the hottest summers this 18xx here :( global warming is no joke
i can no longer find it, but there was a video of a man who was studying ancient Indian (India) technology. He showed how they were able to make ice, on a 90 degree f day. It was pretty simple, and he demonstrated with a bowl of water, taking it from warm to almost 32 f in mere moments. He even had ice forming on the surface of the water

I am starting to like some of these videos especially ancient architecture designs as that is something of hobby for me. A great example and probably in opinion one of the best ancient wind capture and cooling systems of the ancient world is the HAWA MAJAL of JAIPUR - it not only captures the wind to cool but has different size windows that affect the wind speed to speed up and slow down the wind which even during the hottest days can be kept cool inside there can be a difference of like 20 degrees difference from the outside its amazing to see and feel if you can go to India and visit the palace....
In areas that have 4 seasons and low water tables, using an underground air system is viable.
Ground temp at 6-10 foot depths stay nearly constant around 55F. Using a simple solar powered fan and ductwork/tubes an air circulation system can be utilized year round to prevent freezing in winter and heat stroke in summers.
Fine tuning may be needed depending on your region. Such as condensation catches in hot humid areas, pollen filters in higher allergen areas, etc but it is quite basic. Intake tube at least 2 foot above ground to at least 6 foot strait down. Elbow connect horizontal tubing at same depths for at least 20 foot to insure heating/cooling of the air finally elbow connect back to surface levels under or in your building. The smallest of fan will draw the air or even a high window opening would start circulation. Saw it on an off grid home builders show and have wanted one ever since. If you have ever had your water pipes freeze in the same year as it felt like 120F with the humidity you might also want one..lol.
"earth ships" are doing the free geothermal air conditioning today without the use of fans... it's not very difficult or complex
I thought this architecture was just for decoration. Incredibly interesting.

Interesting and timely. I have land in the Chihuahuan Desert region of Texas and am in the process of designing an off-grid cabin for my semi-permanent residence out there. I'll look into making a form of this to help keep the place cool. Thanks for posting this!
That's really cool!! Good luck and i hope you manage to pull it off 🤗
God knows it’s needed and then again it’s dry enough for it in west Texas.
Agreed 🤗
If you're going off grid may I suggest solar powered attic fans, they may work great as a supplemental or even standalone ventilation system.
look into "earth ships" and how they use free geothermal cooling, it's the same principle... the sun heats part of the building and starts a convection circuit and draws the air up and out and the cool air comes in from below where it is a constant 55F... then you just have to play with how much volume to cool your entire interior and then maybe think about mold and bugs and mice...

@Joe Duke Air conditioning, often abbreviated as A/C or AC, is the process of removing heat and controlling the humidity of air in an enclosed space to achieve a more comfortable interior environment by use of powered 'air conditioners' or a variety of other methods including passive cooling and ventilative cooling.
It IS air conditioning. The means of cooling or is irrelevant to the actual means end.
My late grandfather's house had a 'windcatcher', as it's part of my country's traditional architecture. It cooled the house by about ~15C less than outside air. But one thing to note, the entire house design is completely different, the "backyard" is actually in the center of the home, with the building and its' rooms surrounding it, kinda like a big empty square with multiple storeys around it, there are a LOT of rooms that are all square or rectangular in shape. There are also wall openings in each room, 1 to let cool air in and 1 to let hot air out, creating a constant straight flow through the house. These had flaps that can be closed in cooler months. I do know the yard design has a lot to do with privacy, but I imagine the air flow control influenced it as well. Also the very thick walls that others have mentioned, ours were actually built out of crushed seashells and lime, it makes for very rough but very stable and cool to the touch walls. It's great for anybody living in hot desert climates, though in modern times with all the excessive amount of city pollution its very difficult to filter that out. I'm sure modern architects can come up with modern solutions for that though.
It cooled it by 15C??? So if it was 90F outside, you claim inside it would be 31F? That's a bold claim...
@@billymacktexasdetective5827 Your conversion is wrong. 90F is roughly 32C, and 31F is a touch below 0C.
In another conversion (roughly) ....
100F = 38C
74F = 23C
There's your 15C difference.

@@billymacktexasdetective5827why not?
@@diomedes39 In order to cool a space, heat must be removed and rejected elsewhere. What is the source of cooler air that will allow for the transfer of heat from the space to outside? The wind that is at air temperature?
So say it's 95F outside, how is a 95F wind able to cool the inside of the house to 68F???
95F = 35C
A 15C drop is 20C, which is 68F.
If the outside air is 80F...
80F = 26.6C
A 15C drop is 11.6C, which is 52F
Do you buy a 80F wind cooling a house to 52F?
Sorry, I don't, and you shouldn't either...
*I HAVE JUST DISCOVERED* that the soviet era apartment block I live in has this system...
There have always been two vents that blow a very strong cold wind, I assumed it was coming UP by convection from the ground floor. But a quick test with a piece of paper shows it in fact coming DOWN from the top of the building. This explains the odd slightly funnel-shaped structures on the top of the building AND the greats in the floor outside that also blow cold air even on hot days... They are the "overflow" vents in case people have the doors closed to stop the system from pressurising...
WOW - I would never have known but for your video.
rly? in my country only Stalin Era apartaments have it, newer, built after 1955 don't have it
18th century churches have open steeples that also act as wind catchers - but only if the person ringing the bell remembers to leave the door open until the end of worship.
I didn't know 🙂
Black magic! The Devil's work!!
(Sorry, just getting sick of America's taliban morons)
Imagine a neighborhood or town full of houses with wind catchers and solar collection panels...that would be so nice. It seems like it would be expensive to build, at first, but after the techniques became commonplace and refined, perhaps less-so. Get on this, architects!
They're working on it 🥰
Just no. Really
It would just depend on material needed to insure breathing. Like for example concrete wouldnt be good for it. Lighter more porous material would be better.
This tech would be amazingly useful in the Western US which is primarily desert. California for example would benefit greatly with this technology, as it would help greatly reduce the need of A/C units. Tinkering with it to apply without needing to much water would have to be considered however, and of course resistance to earthquakes.
With the current energy issues and the heat issues maybe it's time someone brings this up to the desert States.

Hi Kayleigh, it was very nice that you got interested in this subject. I am an architect and I had studied for my thesis, the great civilizations, Mediterranean Middle East, and in particular, qanats and air conditioning. As part of an economic development program in the 2000s, I presented various proposals for water retention, air conditioning, etc., in the Kirkuk region in Iraq. I had success, unfortunately the war arrived, and the project was not carried out. All architects should be interested in these different typologies of architecture around the world and adapt it according to the place. A big thank you for your presentation, I hope that many decision-makers will become aware of these construction techniques, it would do the greatest good for our small planet! Well done for your work, bacci.

@Armando, you work sounds interesting. Do you mind recommending reading materials for non-engineers.
Thanks for sharing your knowledge Armando!
Yes, I researched this a couple years back, Egypt & Ancient Persia both used this type of cooling ventilation, Iran's are possibly older. They both also invented taxation, Persian king Artaxerxes (pronounces Our taxes) is the father of modern taxation. Then we have glass windows.. Much older than realized & ice... Transporting& using ice, centuries before refrigeration was invented.
It’s becoming increasingly more and more apparent that older civilizations had technology that allowed them to tap into unlimited, free, clean energy as well. The modern day “controllers” are well aware of this and done everything they can to keep this information from the public.

Evaporative cooling. Great for dry regions, wont work in regions with high humidity. Houses were once built with double hung sashes. You raise the lower about half way, lower the top window half way. Cool air came in through the bottom forcing hot air though the top opened window.

I do love these windcatchers, they're fascinating and i don't understand why we don't have them in the western countries 🙂
and likely wont be , power companies dont want the s west to know .
Everything was destroyed in the southwest USA with very few temporary dwellings still hidden from the metropolitan areas. The wars of the 1800's were devastating to Turtle Island / America.
Imagine extracting electricity from the atmosphere?
You will require hot air existing at a higher rate to create a vortex in the dwelling allowing cool air to fan the inhabitant/s.
In my opinion it would appear that the taller tower would be for the hot air to rush out and the lower tower to pull in cool air.
The constant rush of this vortex may produce condensation at the smaller and/or lower tower and in a more humid climate it should give you the opportunity to place plants that produce fruits and vegetables along with the added benefit of generating oxygen.
It could also be a disaster if not well tuned periodically with the seasons.
Do to the potential of this system incubating toxic molds that with time can lead to cognitive decline such as dementia which would eventually be diagnosed as Alzheimer's most engineering firms will not touch this advanced technology.
Nevertheless this technology seems to be working well in these drier regions of our world making it worthwhile for other climates to experiment with in a distilled water extraction operation.

I live on the plains of west Texas. Where I live, the wind blows for most months out of the year. There are weeks where the wind never gets below 20 mph. We also experience haboobs a few times a year. A windy day here consist of sustained 40+ mph winds. We have one of the best wind research facilities in the world. Yet it baffles be that we have yet to implement technology like this. We still don't use wind turbines out side commercial use. The sun shine a majority of the year, and solar is barley making a a foothold in town. It doesn't help that the electric company makes customers jump through hoops to install solar. This is wonderful tech. I wish more people knew about it.

In Italy the ancient Etruscans buried their dead in surface tombs, one of which might be the Cucumilla. The Cucumilla is most unusual as it has two center towers, one square and one round. Perhaps it incorporated a function known previously. IF the Greek Dark Ages was caused by intense light AND HEAT, the design inside the Cucumilla could have been how a large meeting area was cooled.
In all deserts, it gets cold at night. Building a giant tomb to keep the cold air of the night is impressive in scope. Besides the fact that most deserts are on cemented sea beds or bed rock making it very difficult to dig into. This isnt really refrigeration though they arent making any cold. They are just saving cold.
They missed a trick here it could also be used to generate a small current of electricity, using convection current.

as a HVAC-R tech this is interesting but i would like to see numbers to see how well it works in certain conditions. this is already being done it is called free cooling with a economizer. if outdoor air temp is lower then inside temp then draw fresh air in. using the stack effect and evaporative cooling is a neat idea but this will only work in arid environments with low humidity.
Evaporative cooling is state of the art. Highly efficient, problem is legionella or other bacterias and fungi very strict rules apply for supply air conditioning. In my experience you can get 6°C colder supply air by spraying it with sufficient room temperature water (going from 30 to 95%hum). However, the system looses the evaporated water so it is not useful in deserts. There I'd recomend a conventional heatpump. As the humidity is usually undesirable indirect cooling (of another medium using exhaust air) is common. Now regarding freecooling vs this passive wind channeling: The numbers compared to freecooling are easy: You save the fans. So E_saved ~ v_air^3 ~ mdot_air^3.
@@MaxMustermann-bm7qt Another idea you gave me is putting a 1000 liter water tank (1m^3 or 250 gallon) in your home and connect it to some fans to stabilize the temperature in the summer.

As amazing as this is, especially for it's time, it is still only usable in low humidity areas.

Happy new year! The new covenant will not save you if you continue being rebellious and stubborn against the word of the Lord. It is a sin to steal and a sin to forget the sabbath (saturday). *1 Samuel **15:23** KJV - For rebellion is as the sin of witchcraft, and stubbornness is as iniquity and idolatry. Because thou hast rejected the word of the LORD, he hath also rejected thee from being king.* Witchcraft, sorcery idolatry, witches, sorcerers, idolaters will be cast into hellfire. Only they that are washed in the blood of the Lord Jesus and keep his commandments shall be kings and priests. There is no such thing as a sunday rest or sunday sabbath in the Bible. Only the seventh day is blessed, sanctified and hallowed. Isaiah 66:22,23 says that from one new moon to another and from one sabbath to another shall all flesh worship before the Lord in the new earth. Matthew 7:21-23 proves that not everyone that says Jesus is Lord will enter the kingdom. We need to do the will of the Father which is to obey and honor our Lord Jesus Christ. He kept the sabbath, new moons and holy days while he walked the earth. Why do you keep sunday, Christmas, Easter and January 1st which he never kept? Repent.
Older buildings in the American South have high ceilings and a window above each door that can be opened to allow heat to escape by convection. In more recent times, a whole-house attic fan can ventilate a house when the windows to the outside are opened, sucking the air through the house and then out the attic vents. It really works well in spring and autumn, and also helps air the house out. Swamp coolers are something to consider, too, maybe with some modern updates, but they don't work very well in the humid South. They are better for some of the more western and mid western states.
Some combination of these with ever-increasingly efficient air conditioning systems or heat pumps can really decrease the demand for electricity.
Absolutely agree, i do hope they figure out something that works in high humidity 🙂
Transom windows are very useful particularly in buildings with 16 foot ceilings!
Heat pumps in cooling mode are exactly the same as domestic air conditioners. They're no more efficient at cooling. In heating mode they're quite efficient until they hit low temperatures but in cost terms they still work out to be more expensive to run than gas boilers in climates that have cold winters.
@@HistoryWithKayleigh It's called HVAC. It looks like intellectuals are determined to take us back to the dark ages. Fortunately you all will FAIL. Witness what is going on in Europe right now with heating.

This reminds me a great deal of the passive solar heating and Earth cooling principles in earthship construction. Basically, sun facing glazing which is angled enough to minimize solar gain in hot seasons, and maximize it in the cold, while large pipes run under the backside of the bermed house, away from the sun. These pipes are deep enough to cool air that passes through them. The sun heats the front of the house the most, and when the pipes are opened in combination with front windows/skylights, convection draws cool air through this house.
this is it... I've never felt how cold they get, but I've watched the videos about "earth ships" and the free geothermal cooling they use, and it seems very simple, easy, and not very complicated...
@@VenturaIT well of course it's complicated, for one, cooling air dehumidifies it, meaning moisture in the pipes, meaning you need to take steps to avoid mold. That's only one thing, too. Making these windcatchers was surely very complex, too.
@@crimsonguy8696I've thought of that too, but they build these geothermal air conditioners in current times frequently in some of the hottest deserts in Arizona for example... you could ask them how they deal with mold, I've seen them put in screens for the mice and animals... they use large pipes.... does mold need more heat to grow than 55F?

You could use these wind air conditioners as wind electricity as well. Using a series of smaller propellers within the protection of the tunnel would allow easy access for repairs and would protect from environmental hazards. It would remove individual homes from a grid system that ultimately fails in extreme situations. It would be easy to maintain and fix, and certainly cheaper. It would be perfect as well for those areas that have extreme weather. The whole debacle in Texas last winter could have been completely avoided.
Once again, ancient technology teaches us we don’t know as much as we think we do.
Thank you!
It could very well be used for that as well, it's incredible 🤗
The ancient world has a lot to teach us😍
Please excuse me, I’m not being nasty but as someone within the industry I can say this won’t work and is impractical.
These small props running small dynamos would barely make a single small light glow. You may get a small trickle charge into a battery. That’s all.
In this town solar would work much better as there would be few clouds.
As far as Texas is concerned, the problem was cold not heat. First the dynos still would have frozen, second you would have air below zero being blown down the ducting freezing the house so you would need to close off the airflow stopping the dynos. Heating takes a lot of power so they wouldn’t be sufficient.
Again great idea, keep it up but in this case wouldn’t work. Sorry
Could be but they've got the best environment on the planet for solar panels, they'd be better off using their resources on those.
Texas’s problem is they didn’t spend the money to winterize their grid….. blame your state government for not doing the basics of governing. While extreme cold snaps are rare in Texas, they aren’t unheard of and this should’ve been protected against and could have been protected against, they chose not to because they didn’t want to spend the money and didn’t care what happened to people in an extreme winter weather event. I don’t live too far from Texas and in my community our electric grid was winterized, we experience the extreme cold a little bit more than Texas but not much. My state is a small rural state too, and we could afford it, Texas has no excuse. The only thing we had problems with in my state when that happened was the gas companies, and that was more because of their greed than a problem of our infrastructure.
A windmill generally requires 20-25 mph min. to produce minimal power. Even where I live wind frequently blows and people assume it would work but a look at average local wind speeds online shows 9-10 mph. not even close or I'd have several up.

Factories always had tall Smoke Stacks to provide better draft for the Boiler Room.
Wind Catchers pull air Up and out of the building. The lower tower might bring in the cooler air. Hot air wants to rise so the taller tower will create the draft.
When I was attending Michigan Tech and growing up travelling to the UP I was always fascinated by the old smelter towers and how much wind was at the base. Felt really cool too on hotter days. I've had thoughts over the years developing a structure around one to preserve and utilize the differential capabilities.
@@jafinch78 Constant wind makes it feel cool even if air is hot, a combination of thermal mass and wind tunnel effect can be combined ,making life bearable .
@@obiecanobie919 I recall they also have a sun screen design also that helps keep the building cool now that I think about. Something like shades and still lets air flow. Some sort of honeycomb or repeating design. I forget if at night they open up the building also to heat exchange to remove more heat from the structure which definitely is made from a large thermal mass... even if sunk in the ground will warm up during the day and can be cooled off at night.
Would a wind catcher system work in a place like Louisiana or somewhere it’s like 100 degrees and 80 percent humidity? I’m amazed at the ingenuity of people from all over the world and throughout time! Thank you for covering this!

I have seen an interesting design inside a passive solar home. It's a heat exchanger, using a "rock bin" which is a room full of small rocks. Hot air is collected at the top of the home, drawn into a vent that goes to the rock bin in the basement, cools as it flows down through the rocks and is distributed from the bottom of the rock bin.
"earth ships" are doing the free geothermal air conditioning today... it's not very difficult or complex
That's super cool. I can see the benefit in dry desert climates for sure. I do wonder how this works in places with tropical storms though. Would you get a lot of rain in the structure. Places like Central America, South America, South-East Asia for instance where stormy hurricanes and monsune are a yearly event if not more frequent.
I'm a 15 yr hvac professional. The principal is similar to how a whole house fan works. It cuts down the heat load. Most of the heat is in the attic and the whole home holds heat like a sponge. If you pull in cold air it pushes the hot air out. Knowing wind direction. Proper placement of windows and well.built structures will passively cool. However some buildings will always need hvac. Especially in certain locations
Especially when you put many tall buildings close together
@@pauledge1621 Or if the area you live in is covered in trees and the wind does not reach the ground. This would work in a flat arid climate. My grand parents lived in Oklahoma and the wind blew constantly there. Here in southern Alabama it is often still and humid.
I grew up in Hawaii in army housing without air conditioning. Many people had a window unit or two but you really didn't need one because the homes were built to allow great air circulation. In fact, one entire hallway in my house going back from the kitchen to the laundry room was all screen. We had very long overhanging roof lines that kept rain out and precluded the need for rain gutters.
The biggest problem with cooling a house is moving/circulating the air often enough before it has a chance to build up all that trapped heat from the sun.
Like Houston, TX or Buenos Aires, Argentina! I'm retired from HVAC and resided in both places!
Interesting n informative thanks South Indian Hindu Temples r built to keep the interiors cool airy at the same time with enough natural light similar vents r built for light n hot air exits. Row houses have this type of wind catchers n hot air vents. more research required in this to reduce Global warming EL NINO. etc
That was super interesting.
It's definitely dependent on where you live (what can be done to combat heat and cold). Where I am we have mostly dry winters, no snow here, very little rain, very very little clouds, wet summers, mild to extreme humidity, lots of thunder storms. So, my solutions: 1) in winter: if there is sun (and outside is warmer than inside), open doors/windows until just before sunset/until the air starts cooling, then close everything up, to keep the heat in. 2) in summer: when (if) it gets cooler in the afternoon, open doors/windows until you go to bed. Keep them closed during the day. It's considerably cooler, as long as humidity and heat have not persisted for days, if heat has persisted I find it more effective to have a fan blowing air out of a room, on the sun-facing side of the house (bonus if you have a fan to blow air in from the non-sun-facing side, or into the house from a cooler room).
Using my thermometer I have noticed that even though a winter wind feels colder (because of evaporation off of your skin) the actual temperature is most often warmer than the inside of your house, so on warmer winter days I set up my fan to bring warm air into the house through a window on the sun-facing side.
I thought this would be easy to explain. lol. This may or (probably) may not apply to you :P
Thank you for this lovely and extensive response 🤗
I can’t believe I’ve never heard of these fascinating ancient inventions! I’d very much enjoy seeing a more in-depth look at wind-catcher types and functionality. ✨👍🏽Very cool.
I'll be doing that in the future for sure, first i have a stack of videos to create haha 🤗
@@HistoryWithKayleigh Good morning Kayleigh. The mark of the beast will be IN the right hand or IN the forehead. It is spiritual and physical. Most of the world worships the beast by keeping sunday, friday, Christmas, Easter, Eid, Diwali, etc. There is something physical coming that people will have to take if they want to buy or sell. Muslims go to the mosque on fridays. Our Lord Jesus never ate shrimps or pork. Prayerfully read Leviticus 11:43 and Revelation 21:8. If you make yourself abominable, that is a sin! Repent.
Happy new year! The new covenant will not save you if you continue being rebellious and stubborn against the word of the Lord. It is a sin to steal and a sin to forget the sabbath (saturday). *1 Samuel **15:23** KJV - For rebellion is as the sin of witchcraft, and stubbornness is as iniquity and idolatry. Because thou hast rejected the word of the LORD, he hath also rejected thee from being king.* Witchcraft, sorcery idolatry, witches, sorcerers, idolaters will be cast into hellfire. Only they that are washed in the blood of the Lord Jesus and keep his commandments shall be kings and priests. There is no such thing as a sunday rest or sunday sabbath in the Bible. Only the seventh day is blessed, sanctified and hallowed. Isaiah 66:22,23 says that from one new moon to another and from one sabbath to another shall all flesh worship before the Lord in the new earth. Matthew 7:21-23 proves that not everyone that says Jesus is Lord will enter the kingdom. We need to do the will of the Father which is to obey and honor our Lord Jesus Christ. He kept the sabbath, new moons and holy days while he walked the earth. Why do you keep sunday, Christmas, Easter and January 1st which he never kept? Repent.
This is Amazing.. Actually This is How I found out All about yr program's. A sweet voice that draws the history into a New life in One's mind's. Thank you 💕
Great video and highlights of some historically significant passive cooling design strategies. I'm a mechanical engineer who has included a few of these in my own building systems design, but their practice is uncommon and I'd guess that most architects and engineers in the USA have never included any of these strategies in their designs. Modern A/C makes it too easy to just throw in some A/C and be done with the problem quickly and easily. One local architect that stands our for using wind and adiabatic towers in multiple projects is EHDD in San Francisco, CA; The Carnegie Center for Global Ecology and the Zion Canyon Visitor Center are two project examples that come to mind.
subjects "down to earth" like this need to be addressed !
It feels great to dive away from megaliths blocks and civilization collapses sometimes x) and remind us we're closer than all the simple people than we often think about ;)
Absolutely! I love all aspects of ancient history 🥰
When it's hot and humid instead of using the air conditioner I open the east window with my 22" fan blowing out then I open one window on the shady north side of the far west bedroom. This pulls shaded air through the house and keeps things bearable(not comfortable) in July and August. I also use three smaller fans as needed but even all fans on high speed costs less than air con,like maybe 1/4 the cost. That's all money I can save for winter heating which can be a long season here. Not as economical as a good passive cooling system but it does ok for now. I have done this for twenty years here but when I grow elderly it might not be enough.
At least you're not running your ac 24/7 🤗
**ventilation!
Air conditioning by definition has to dehumidify and actively chill the air :p
This wind catcher method of ventilation is so clever, I definitely wish it was more common! Even in places where air conditioning is necessary, it would help the efficiency of the a/c by cooling the building more effectively at night!
Since I first got into greenhouses, I have firmly believed the technologies behind this video (and the ice house). Now, 30 years later, I finally have the time and resources to do some of them and just at that time, I find you with the histories that were missing from my limited knowledge. I'm going to enjoy this ride! Thanks for the videos!
"earth ships" are doing the free geothermal air conditioning today... it's not very difficult or complex
Fascinating! I'm having a ball going through some of your older content that's all new to me here in 2023! Thank you.
Well done...I would love to hear your take on the Mudflood and Tartaria...LUV BEAGS
I can always take time to look into it in the future 😉
I just discovered your channel and after reading your "About" page I must say you're a very funny person. The concept of wind catchers is pretty cool. It would be awesome if it caught on here in the American South, well all over really. Designing them around hurricanes and bugs would be a challenge though. I'm looking forward to watching more of your content.
Thank you🤗 happy to hear my humor in the about section is appreciated 🤗
Thanks Kayleigh. Fascinating. Clever passive engineering technology which means it's low cost. The problem though we have in the Wild West -- that's where the smoke is coming from on the satellite photos -- is that when it is really hot it is because the wind has stopped. The good news in those moments -- the utility industry has called this the Hundred Hottest Hours problem, for which the grid is overbuilt to meet demand when the sun is out and all the AC units go on -- is that The Sun is Out.
Using low cost parabolic troughs with mirrors or aluminum we can produce steam at a cost roughly competitive with Natural Gas at $1 per mBtu (and it's around $4.50 now in USA -- Europeans are being gouged at 12.50 now). In other words, at that price, it is gravity and will start to matter, at scale. Hook the steam or hot water from the trough to a low cost chiller and voila, AC. I reckon it is the lowest cost solution to the utilities' biggest problem.
Furthermore, with these troughs we can desalinate seawater -- it's a still. The boiled water that evaporates and re-condenses has no salt in it. The trick is to get the salt back to sea safely, not on the shore which will kill everything. Drones anyone? A rant for another occasion. Aerial or submerged.
I appreciate your tutorial and the Persian architecture is something we should all admire and emulate where suitable.
Did I mention that Wind is The Air Apparent? It can replace all nuclear power stations in a few decades at a much lower cost without any risk to human life. The birds will figure it out especially when you paint every other blade. The renewable wars are over and we've won; it will just take time for the orchard to bloom in full. From then on we can live off our income (sun, wind and rain) forever. What's not to like?
Everything to like that you write here 🤗
Solar stations create micro climates and can kill entire flocks of migrating birds. They're a great option, but only efficient enough when using salt as a medium. If the objective is desalination, sure use water; energy is the bonus in that case, not the objective.
Wind power is great, but not without massive downsides. It cannot be located in populated areas due to the psychological effect the chopping noise and light disruption. They require massive areas of land, IE disruption of wild spaces or farms. The effects on wildlife, including migrating birds and land animals are severe. They create catastrophic deadzones where wildlife cannot inhabit for the same reason they can't be placed in towns and cities. Just painting a blade doesn't solve diddly. Birds can see the blades just fine, better than we can. They're taking the risk that they can get through and failing.
Dumping salt back into the sea is painfully stupid. Sure, eventually it will disperse, but it will increase the salinity of the local area wiping out all sea life. Furthermore it's a valuable commodity, no reason to waste it when it can be used. Even if it were to be a waste product, dumping it in salt pans would be the best solution.
Nuclear power is the least damaging, least wasteful, most power producing of any of the above options even taking into account the catastrophic risks. It won't solve all our problems, but it must be part of the solution. I'd rather live in Pripyat than in LA because the air is literally safer to breath. Hell, the air in Utah(where I live) naturally has more radioactivity than the Chernobyl exclusion zone simply because of the uranium in the rocks and dust. I'm not discounting the dangers of nuclear power, but I'm also not an animal shitting itself at a hearth fire because I can't understand how to use it safely.
The "renewable war" is a marketing scam to sell government officials snake oil and sell the public on politicians willing to do something new and exciting instead of using proven solutions we have known about for over a century. Even fossil fuels have their place. The reality is that we need all power generation options or we are screwed. We also need to recognize that there is always a cost, there is no free power and no free resources. The reality is that as a species we need to think long term, in terms of generations rather than decades or petty election cycles. We need to stop looking for easy ways out of our problems, we cannot afford that cost anymore.
@@OspreyKnight Big solar isn't the way forward. PV is infinitely scalable and virtually free, being made from sand and collecting free energy from the one fusion reactor with the engineering worked out and perfectly sited, far, far from here.
Nuclear energy is the only power source that the market will neither invest in nor insure. For a reason -- Too expensive / Too risky / Too late.
Even the Japanese can't keep them safe and it's a technology that does not allow for errors. Read Rylands v Fletcher in re strict liability. (English High Court 1868).
Game over. All over but the shouting that is and this is Kayleigh's channel not mine so let's not start shouting at each other. Besides, she is busy right now watching her Boys in Orange teach the Turks a lesson in how to play proper football. 2-nil so far.
Memphis looks pretty good today, Ms. K.
@@henryhewitt1571 Welcome to the internet.
You are a product of radicalization, not rational thought and knowledge.
Its not a competition. If it's a competition, drill for oil, its the cheapest energy source available. We can burn this planet to the ground until we finally decide it's too uncomfortable to live here and leave.
"Even the Japanese" that's racist. Nor is the nation of Japan the best at environmental issues.
You're totally right. The market for nuclear power is completely poisoned by ignorant fucks who would serve humanity better as fertilizer.
"Read Rylands v Fletcher in re strict liability. (English High Court 1868)" Jesus Christ....
""the person who for his own purposes brings on his lands and collects and keeps there anything likely to do mischief if it escapes, must keep it in at his peril, and, if he does not do so, is prima facie answerable for all the damage which is the natural consequence of its escape"
"Many courts in the United States have attempted to use Rylands to justify absolute liability, which it was never intended to do; while absolute liability is where no defense is applicable, in Rylands itself Lord Cairns accepted that there were some situations where the case should not be applied"
If that applied to power generation there would be no coal, natural gas, or wind power. All of them on a big enough scale cause damage outside of their property. Even Solar has environmental issues that extend past property.
It would also be damned impossible for nuclear power, the most highly regulated form of power generation requiring its own energy commission, to have all blame for a disaster lain on the private company running the power plant. Thus totally invalidating the Rylands argument. TLDR, if something goes wrong at the plant, the government is ALSO going to be at fault.
No other method of power generation on a national scale can beat nuclear power in terms of safety. The reactors available now absolutely cannot cause widespread damage. It is physically impossible for them to do so. It would be legally impossible to build those other types in the US because of their potential risks. The waste products are almost comically easy to dispose of if it weren't for the morons mentioned above.
A lie unchallenged is tomorrow's dogma. I won't leave your BS unchallenged, because its already well entrenched dogma fueled by ignorance and stupidity.
@@henryhewitt1571 Wait a fucking minute. We don't have fusion power yet. What smoke are you cracking?
Very interesting topic, thank you for that. Marvellous visualizations!
The drawback of AC is that multiple units blow hot air around a city and when concentrated together in a smaller area, they create heat islands which raise the external urban temps.
That can happen with or without AC. It more reliant on the building design, color, and density.
I’m Iranian, a lot of things were invented in Iran ( great Persia) which most people not aware of it and because of bad regime in Iran , western people think we are uncivilized people. I hope we people of Iran get rid of evil regime in Iran and gain our respect from world again.
Your country has my respect 😉
@@HistoryWithKayleigh thank you 😊
Much respect to the middle eastern nations for their innovation in architecture, and especially medicine. While Europe was practicing medical superstition, the ancients of Persia had reliable, learned physicians who understood physiology and could actually heal people.
Persia was a very important region for knowledge . Many things were first developed there. In particular mathematics , and geometry , but much more.....
This has been truly fascinating. I've been being mis-directed every time I type into my browsers of how to find these types of resources and am very glad that this came across in the you-tube pop up. Thank you so much for expounding on this type of experience with science and culture. LT680 Southwest Mo.
Happy to hear you enjoyed it 🤗
This is a great example of how the ancients did things better than ourselves today. The mysticism is the understanding of enviornment, practicality, engineering, sustainable materials, and local agriculture. I wish we would create more structures and technology with environment and sustainability in mind.
Please Please... stop adding traditional folk Arabic music to every middle eastern topic! Espasholy when talking about Persian culture as both are separate cultures and languages! Thank you
Why did the indigenous people in Latin America store water in clay pots ... and especially certain types of clay? Because it was a semi-permeable mud, then the vessel "sweated" and that cooled the water by evaporation.
Very smart!
I absolutely love love LOVE this. I build homes in Phx Arizona. I seriously am considering doing a build using this.
Oh wow! I wish you the best of luck! 🤗
I think building wind catchers for apartments would be more efficient than for single family homes
You better get a good supply of cream for your skin and lips!
I'm in Yuma....these could work except during the monsoon season..I think.. It's definitely interesting and I'm curious as to why we don't use them here. Now in the past we used to use water assisted air conditioners with water towers in the backyards (tall with wooden slats) and water would run down them cooling the air and pumped into the home but as I said that was a thing of the past.
@@daenas Those water towers are still in use in large buildings like hospitals, movie houses and theaters/supermarkets.
When you think of the engineering involved to build these, and my guess, the trial & error to get the technology correct, it’s just amazing.
If you put in perspective building pyramids and moving 200 ton megalithic rocks and getting to fit like a jigsaw puzzle, re-directing air was probably child’s play.
For someone like me that tries to predict lightning in a 2 1/2 mile radius, my day is filled with atmospheric static electricity and negative and positive energy imbalance. I have the benefit of a sensor that’s checking the precursors of a lightning strike 50 times a minute, a computer and an algorithm doing all the calculations. How these people (all over the world) did what they did is just incredible.
Absolutely agree, they were so skilled and knowledgeable 🤗
@@HistoryWithKayleigh what I was led to believe, at least in Egypt, people would sleep on their roofs to escape the heat. I just took “roof sleeping” as fact. It wasn’t till yesterday thinking about that theory and wondered as tightly packed as some of these houses were, what if one of your family members or neighbors snored?
Maybe worse, what do you do if one of your younger neighbors missed out on the “decorum gene” and had no issues with public displays of affection?
I’m thinking the redirection of wind would be best for everyone. Including young children…
These are a more simplified version of the swamp coolers used in the south western part of the United States. Although the swamp cooler uses a "grass" filter, constantly flushed with water to provide evaporative cooling. Along with electric fans to move the air. While this is ingenious ancient tec, im just pointing out that modern man has,somewhat, adapted it. In no way diminishing this incredible achievement.
That's great! 😍
We have them here in Northern India too. We call them room coolers.
damn as a mechanical engineer i would really like to work on a design to retrofit current homes with something like this. if only i was back in school! this would make such a great thesis.
It would for sure 🤗
While looking for a house years ago we went through a house built in the 1910s that had a pump from a sand point well discharging into a huge radiator about 10 feet wide and 6 feet high at a 45 ° angle that shared the gravity flow coal heater and cooled the house. The catch basin was pumped back down another well returning the water underground. Kansas.
