Seviyorum seni Müslüman kardeşim 🇹🇷
I'm an engineer working with Nitinol, Ive been working on a way to power a ranch using a Nitinol engine that uses a sand battery for its needed heat exchange during the nightime hours. I dont know why anyone isnt working with this very simple and very effective technology but they should be. Its something most handy people can build and easily power their homes
Maybe make a big metal spiral (or few of them), like in electric oven, then put them inside the sand, to heat it up to at least 250-300 Celsius or much more!
Can end up requiring few kW of power (with few spirals), but looks like a decent idea to test it.
And it would be great, if you really decided to repeat the experiment with bigger container! ♥
This is certainly an interesting thought. I work at a sand mine where I dry sand with a giant rotating oven and send it to a silo; and a month after filling it, it still comes out of the silos very hot. I had not thought about how it held heat but it certainly is giving me a few creative ideas.
Gheez, talk about working in the right place:) Good luck. This ought to be a no brainer
Please do build a larger sand battery!
Maybe we should be putting sand batteries underground for better insulation?
Another possibility is that we can store cold as well as heat. The idea is to create a temperature differential. It doesn't really matter if your thermal storage is hotter or colder than the ambient. So we could store heat in the day to power the night, and cold in the night to power the day. With refinements, there might be a way to use the heat differential between the heat store and the cold store to get a higher differential that's sustainable over the time it would take secondary system to charge its hot and cold sides. Or maybe you would need to rotate 3 or 4 systems depending on the recharge time. That's something for the research to figure out.
That's a simplification as temperatures are more complicated than that, but it's the general idea. It's going to be fun watching the tech develop in this area.
An elegant, practical and resourceful solution, I think, to longer term storage solutions.
You can use water for that
They did that in the olden days with wood chips. They would bring in ice from a lake or river and put it in the persons chosen area and cover it with a pile of wood chips.
Gravel is better suited for this purpose, because of the gaps between the individual stones they can easily be heated by passing hot air through them and then there is no need for copper tubes
5 hours for 5kg is not bad at all. It would be a pretty good system to put a sand battery in a basement of a home and store all the heat in there.
This would be much longer if he used any kind of insulation too.
except the method to heat it was very expensive
One of my favorite topics!
I wanted to build a prototype where I would put some sand in a (heat-insulating type)cement box, and have the heat transfer with (compressor)parts salvaged from AC. The whole thing(heating included) would run on some solar panels, so long term energy storage testing could have been made possible..
I wanted to build it too, with double sheet metal enclosure with glass window on the outer enclosure and vacuum between those two metal enclosures.
Would use mirrors to direct sun energy trough that mirror to heat internal enclosure with sand inside.
There would be pipes around outer encloser and it would be well insulated.
So when you want to heat the water that you are pushing through those pipes, you just lower the vacuum between those two enclosures and the heat from inside enclosure start to heat outer one with pipes..
i want to see a sand battery built directly into the front or back yard. lets say 100kg sand battery and use a heat pump to heat it like a geo thermal setup
nice idea. Would love to see the bigger sand storage!
I would like to see you use a sand battery to heat a greenhouse at night. Heat the sand with a 12-volt electric hot water heater heat element that gets it's electricity directly from a solar panel. It would never actually be switched off. When the sun is shining the electricity from the solar panel heats the sand. At night when the sun is not shining the hot sand gives up the heat to the greenhouse. Can you do that?
There is are videos of this on YT. People use solar back packs and buckets for shelter and tent heating. You can put several of this in your greenhouse, they will work perfectly!
The DIYers who have tried this found that they needed to swap out the water heater for a stove coil. The water heater element was burning up without being submerged in water to cool it.
Also expanding the stove coil so that the heat dispersed better throughout the sand seemed to have better results.
dual heat it.....use the elements on bottom and use a glass panel with a flat fresnel lens on to to superheat the top......sha shaaaa.....heat!!!
You should try using a high power electric heating element that heats the sand from inside. Great video!
Ok so 55 gallon drum with 4 3in exhaust pipes running threw sand and a heating element in sand with R60 insulation around it cost is about $600
definitely would love to see you build a bigger one brother!
Sand can keep heat for long time but during winter when you start to circulate cold water or aire to heat in that exchange you will lose all the sand heat very quickly.
sand will heat up slowly and release the stored heat slowly to air. With waters higher storage capability, it's like this would drain the sand of heat much faster than air.
Would it make sense to use fresnel lens with solar trucker to heat the sand? Thank you
A full build video would have been better than the theory of a commercial company just a thought
Ooh this was interesting thank you
Im interested to know how to extract energy out of heated sand ..
It will radiate the heat. If that's too slow you pass air through it or around it for add convection. You could also pass water or glycol through it to increase the draw but the fast you pull heat out the more quickly it will be exhausted of heat.
Use a resistor in the center. Like a water heating element. Don't go above/near the melting point of the metal the wires are made of
I'm planning on building a 450 kg sand battery. Planning to have it done for next winter.
Tell us how it goes please
@@jorgeacosta2815 I'll remember this comment
are you going to record it? Ireally like this idea of sand battery- I alsow atch off-grid Mike who done some prototypes and he is currently building the large one.
we would appreciate if you care to record and post them on youtube, does not need to be edited, just some crappy videos are enough 😂
@@shadowmistress999 I will record it once I'm done with collecting the sand. It's gonna take 48 hours total. I've come up with the best design possible to have the most efficiency. Now it's just a matter of building it. Still need to research more on the heating rods and the container type.
Try using molten lead as the conductor, or mercury, instead of air. Make the spiral tubing and checkout the tubes/kg of sand.
Dear friend, Greetings from New Mexico! I very much enjoyed your presentation, and and learned much.... cheers!
Very nice work, indeed! Congratulations from Portugal.😀
ASALAM O ALAIKUM wel hi there hey brother make a huge sand battery that we can benfit from it .. and if you make large size of water heater and use the barrel instead of drum will that help see you in a next video IN SHA ALLAH
Wow nice video! :D We are working on it to turn the heat from the sand back to electricity. And many cases we can use the waste heat from the turbine condenser so the efficiency goes up significantly. Total efficiency can be as high as 90% for combined heat and power plant.
You can also wonder why we just don't stop all the cars and condensing power plants which has similar efficiency, 20-30%? XDD
Make a bigger sand battery using Solar panels and heater coils please. If it can reduce the evening peak hours that will be a big save for the world. No need to run overnight.
I want to make one too. FYI I got a river near me to collect enough to build enough of them to give heat to 15 houses without the city knowing about it. I am planning on using solar panels to power them.
I wonder if a electrical resistor buried in the sand would do better. The resistor can be powered by solar panels directly increasing eficiency
That's how the Finish company does it.
Tried that, it works, but the problem with the electrical resistor is the short circuit protection. The heating element should not touch itself or the cage it is in. My practical thinking was to put it in clay/ceramic to be sure it can't move.
We can also use sand battery for making electricity by using a steam turbine with a liquid with low boiling temperature.( we have to choose this liquid according to the heat capacity of sand battery). By the way, love your this type of videos.
Wow, did not think about this kind of liquids, do you have any solutions for liquids?
@@engineericly Sir, I don't really know about those types of liquid but I'm pretty sure that these type of liquids are there. I was just proposing a idea but if you research than you could find this liquids. Or if you don't find any, do the thing science is known for, that is "experiments" with different liquids.
@@engineericly I thought for a while and came to conclusion that alcohol could work. (But take everything I said/wrote with a grain of salt because I'm no expert on any of these things, I'm just proposing a idea with my knowledge from my science lesson that states that every liquids have different boiling point)
@@engineericly any alcohol should fit the bill. but i would encase a copper coil in the sand and then use car anti-freeze in the coil. use a double boiler to get water steam from the antifreeze heat.
Instead of using a liquid with a low boiling temperature, you can use a water's vacuum boiler/heat exchanger to produce steam. Vacuum boiler brings the boiling point of water significantly down
you showed us how to heat it up but you didn't show us how take an electricity from it as an energy source
but the idea and effort that you spent to do this experiment is great , keep it up ❤
As said in the video, it is used as heat to warm homes and water
You can also use a sterling engine powering a generator for electricity. Use the warm sand or hot air from the sandstore to heat up the "warm" part of the sterling engine.
Several ton build. Yes I'd like to see that video
yes please do bigger test and better options for diy to do this setup at home to utlize design
Please do a bigger build, this really interesting
Please make it biger :-)
And isolate it better ...
Thanks for te video
i want to see a giant diy sand battery, i hope you can do it.
Haha would like to see how you isolate those several tons of sand :p cool idea though! I mostly wonder how you would regain the heat from the battery, or maybe even turn it in to electricity, regardless of the lower efficiency.
can make steam....steam turbine etc etc
Stirling motor.
The surface area, where the heat loss happens, increseas slower than the volume. That's why this technique works best with large units. Sand is also poor heat conductor, so in a way it's an insulator itself.
Good job bro👍👍👍
Please build a bigger one. Also, test using electric heating element vs hot water to put heat in storage and other loops to carry heat out to be used for room heating, cooking/baking, drying food for preservation, drying clothes, and distlling water for safety.
What if you heated the sand with the same technique used to make a fluidized bed?
Ha mayli you video great thank you
Thank you too
What hot air being injected directly underneath/in the sand to cause liquefaction? To get the temperature up quicker; at higher volumes of sand, more air inlet manifolds (injection points) maybe be embedded in the sand.
I have been thinking about combining a sand battery and a wood fired rocket stove to heat it. Any idea if that will work
I've been thinking the same thing. At this point in thinking about it I'd like a rocket heater on a dolly with the sand as mass. The large rubber tires make it easy to move outside to fire up the rocket heater to heat up the mass before night fall. Then put the rocket heater fire out and wheel it indoors to radiate the heat for hours. Even without a fan on it, it would slowly release through the night which is fine.
Separating the rocket heater from the mass would be tricky to make resilient but if it could be done you could add more mass (sand) and a more powerful rocket heater that's stationary outside.
I am thinking a sand battery can be used to store direct solar radiation heat for use as radiating heat in the nighttime. The sand can be heated during the day and moved into a house or my main idea being into a camper or van. Ideally it doesn't have to be moved, but that means it would have to direct dangerous high amount of concentrated solar into the middle of a living space during the day. Too dangerous at first glance.
This method can be used to provide supplemental heat above which a more controlled heating method such as the standard heating method can control the temperature, and its use will clearly go up as the sand loses its heat later in the night.
Another idea that many others have had before me too is to use a sand battery to be able to convert to electric energy at night (or any future time before heat has naturally dissipated). Converting sand heat into electricity is an interesting challenge that I don't think has been attempted on a DIY / personal scale.
Finally, it may be possible to produce a sand 'cartridge' which is a box shaped container of sand that can be heated with an array of concentrating mirrors. This box can be be the shape of a mattress or half of that possibly.
After the sun sets, it can be slid into a frame space carefully located under a mattress, the frame which has insulation on all sides. The top side can be adjust to release more or less heat. This might be practical in van camping where the mattresses tend to be in the back of the van and there is usually space underneath them for storage.
A real simple analog albeit small scale, is the hot water bottle which I previously thought as laughable but is an excellent method to maintain warmth and is used by many people.
I would like to see a calculation for physical size of a solar heated sand battery for 1000kw per month or about 12000kw yr. How much sand is needed at what temp to create that battery? I am taking a random guess at 10k to 20k kg but can anyone calculate it out?
I would appreciate the bigger scale model and Watt*hour or Joules measurements. Amp*hour in case you decide to transform it into electricity. Good video
500k soon....🎉🎉
Hello! I am planning on building a sand battery as well at home. I have a 30kW solar system, and I want to use the energy stored in the sand battery to generate electricity. Maybe you can do a video on this or we can share some thoughts for an experiment. I'm in southern Austria near the Slovenian border.
Thinking the same, i have 15kw of solar PV, self sufficient for electricity year round, so 15kw roughly here produces 14,000 kwh, consume about 4,000 kwh in electricity, the spare 10,000 could be diverted to a heat store, I was thinking off using gravel/dust its much cheaper than construction sand, sunk into a pit, only insulating the roof of the pit and cover with 1m of soil. They have done this in Denmark
Can you put it under your driveway, soo all heat that leaks melt the snow?
Bro this v8deo is so good that it looks like a cubic meter of fossil earth has been sculpted into it.
One thing to consider, just like it is inefficient to convert heat to energy, it is inneficient to convert energy to heat to store it, it is better to produce thermal energy and store it which can be done with modified renewables
Did you not watch the full video
Please make a larger sand battery that's on a dolly. You heat it up outside and then roll the dolly sand container to indoors to radiate for hours.
Perhaps it can be heated with rocket mass stove using the sand as a thermal mass. Maybe the rocket mass stove is integrated with the sand on the dolly.
The above dolly/sand/rocket mass would be practical tool to heat a home in an emergency or supplement a heat pump when it's less than -15C outside.
is there no solution to convert the thermal energy into electrical energy find a solution for this
thank you
Beneficial ❤
I hope, thank you for the feedback!
Its not clear you used the battery to actually heat your house. Could you post how much hotter it made (one room of) your house?
please build large battery
Nice, Keep playing 😊
Really interesting trials, and thanks for sharing Khadas, never heard about that. The religious speaking in the end is kinda something to not say, specifically for international audience. You make great videos, dont let people focus at the end on what you say, as hint from someone in the industry ;)
Keep up your good videos!
Nice job Jahongir
Rather than heating using electricity
Use strong big magnifying glass(I mean those massive lens) which will be placed above during day
The cost of materials to do that will be the same as solar panels. Not mention. Those magnifying glass will need electricity to automate the whole system.
One 15 inch decorative milk can. One bag of playground sand. Either a 12 volt immersion heater that plugs into the cigarette lighter socket OR a 12 volt hot water heating element from a RV dealer. One UBS powered mini desk fan. Be sure to set that milk can on something to insulate it from the floor. One 12 volt car battery. Solar panel of sufficient wattage to charge the car battery from the drain overnight. From the solar panel to the car battery. Battery to the heating element. Mini fan to a socket UBS charger hooked to the battery (drain on the battery will be negligible). Fan to stir the heat coming off the milk can.
Will sufficiently heat a 12 foot by 12 cabin over night for sleeping. And the remaining heat at the top of the can will heat an 8 in frying pan to cook your breakfast.
You may even want to slightly open a window.
I have one in my living room with a water heating element. And a smaller version made of a 14 inch decorative SPARK pot bellied stove with an immersion heater as my element. My power source to the two ancient car batteries hooked in parallel. My living room is 14 feet by 18 feet and the kitchen is 14 feet by 12 feet.
Most days it stays around 68°F and the highs have been in the 40° range. One night the electric furnace kicked on. But it was 18° that night.
The ladies at the city hall always want to know if I am freezing in here.
My electric bill this past month was $36.73
😅😅😅😅😅😅😅😅😅😅
Oh, and the cat goes outside to cool off
water heating elements are bad for it- you need it from stove or water boiler.
Im curios can it use a heatpump? In summer AC would suck out the heat from the house and transfer it into the sand? 🤔
I wish that was possible
Please make the battery. Even if it's only the volume of like 5 barrels or around there.
Zthank zyou

Would like a practical home build without 3D printing
Assalomu alaykum wow Astonishing😮
Am planning to bury 200l steel drums filled with sand lying on sides with bungs interconnected top to bottom in series with steel pipes, blow air heated by parabolic sun tracking dish through sand with a solar powered air matrass pump
Please find a creative way to create sand battery at home to heating one room and water.
How about a DIY solution, try a 55 gallon barrel/drum. Consider a manifold to multiple drums. ETC.
How about salt instead of sand?
I'm gonna give it a try with 32 gallons of sand heated by an electric stove inside the battery. I will have to modify and resign that stove.
So i think up until 2030,we will hear a lot of new technology for climate change every month.. This is game changer, revolutionary etc etc.. But after 2030 this bubble will burst and the realistic technologies will remain in the industry
You say sand have more thermal capacity than water. What would have more thermal capacity than sand?
What about an insulated tank of heavy oil? Run a copper water line through it to convert to steam for heating a home. 🤩
Came in for a battery, was greeted by zen and vinter, wtf
🔥
Thanks :)
Yes please - go bigger but also use an internal radiator for thermal charging/discharging. You need a large surface area.
cool
Thank you!!!
a good video.There are just too much theoritical explanations and examples before the battery building
Build a proper sand battery this time.
Why not have a cylinder full of sand which you can both lift and heat up?
I'm joking..
Make a shipping container into a sand battery
I love vinter time
I could see hot water tanks be replaced by sand tanks that heats water and blow warm air in homes
yes several tons of sand would be a much better experience to measure the effectiveness of such a system ...;

This whole thing being green and really helping the environment depends a lot and I mean a lot on what sort of sand it uses and where it can be sourced from as we're already using more of certain sands than can be obtained in a sustainable way. Unfortunately the fact we need loads of certain types of sand has already caused vast amounts of environmental damage and believe it or not a huge black market for those types of sand with entire beaches being basically stolen over night. I know mad but still. If this uses any sand, preferably sand from deserts then it's all good if not....
O'zbekchayam gapirsez bo'larkan😢
Sir, you have titled your video. Please, then, just stick to the title subject. We're not stupid anymore. Just cover the title subject. Thank you.
Dude. You won't be able to build a sand battery that size effectively. That takes a lot of resources and money.
This is silly. You used gas to heat the sand! It should be storing energy.
Are You from israeel or Palestine?
Trillions and trillions of dollars business in the universe years 2024 sand batteries
i do have better technology....
Try to leave out the CO2 emissions nonsense and just give us the facts of the battery.
I'm glad I'm not the only one who's grown tired of hearing this.
@@masovelikarma618don't worry, you'll not need to worry about hearing about climate change
Yes chemistry is nonsense now. Be hard to say anything you watch is real if you just pick and choose what is real and what isn’t based only on politics.
You are tired of being informed about an issue being presented with context?
I watched the video twice and still can't understand him...
5 tons of sand = 5000 hours of de-heating?
nope.
you lost me at fossil fuels affecting environment badly....
Got any better ideas
