Allen Loser hi, evolutionary psychologist with a background in evolutionary anthropology here 👋🏻 you’re referring to sexes. Gender can refer to sex but does not have to. Gender is typically associated with language and ideas. Neutral gender pronouns have been around for as long as we can tell. Gender norms actually are arbitrary and have been for a long time. I’m not sure how social sciences are an impediment to STEM studies. Most of my closest friends are chemical engineers and don’t seem to have a problem with it. The issue is really our education system and it’s inability to make kids want to learn. And yes the bureaucratic red tape and complete undervaluation of teachers plays a big role. [edited for typos]
Allen Loser additionally- I didn’t not intend any of my previous comment necessarily as an argument but more as some interesting ideas that relate to the conversation. Cheers
Just found this video and subscribed. As a HS science teacher I assigned this as mandatory viewing during the pandemic. This is SUCH A FANTASTIC job of demonstrating, explaining, testing ect... Seriously, one of the best engineering videos I have seen.
David, I think my family just heard me scream YES thru the walls from my shop! Check out parts 2-4 as well if you haven't already, my "2 Liter Bottle Compressor" video (great example of PV=nRT) and keep an eye on my other channel, BUILD2. I just uploaded a video there about the value of working in teams and plan on uploading some content walking people through my calculations. I'm a busy guy but if you have any insights you think I could use, email me: BUILD2LRN@GMAIL.COM Can't guaranty I'll respond but will try.
My kids are all homeschooled. When I saw you actually explaining how to calculate things I thought, "YES!!! THIS is what everyone fails to do!" I just told my kids, "See? This is what you can do when you learn math. All of those people who say, 'I don't need to learn math. I'll never use that in my whole life!' can't do the cool things because they never learned the math to do the cool things. No, they won't use math. But that's not because there's something wrong with learning math. It's because no one ever showed them all the cool things they can do with math."
Did you explain to your students why there were three utterly different results with the same wheel? Specifically the fact that with the tap he backshot the wheel, with the first test jet he overshot the wheel (getting the best results) and then in application he UNDERshot the wheel for some reason utterly defeating the purpose of a pelton wheel by having the buckets carrying water uphill for a good portion of the cycle? Or did you miss a great learning opportunity?
I'm about to get my engineering degree, and I must say he does an excellent job of presenting the proper mindset: analyzing the problem, check the math, and then weigh out if it is worth it. This should be shown to all high school students.
I absolutely love the format of this video. You go through each step of the process: the idea, the problem, the potential solution, the reasoning, the design and paper calculations, the actual building process. This is excellent teaching material and a real life experience of a very complete engineering process.
When it comes to engineering, almost all Americans use metric. The only reason that imperial is still dominant is that most Americans don't use it as their primary system.

Great content for science classrooms. Love that you include design drawings because a lot of people think you just try things until something works but design first build second is so important.
@@nicoj.8242 no need an angle for that. A 1.8 gal/min is a 1.8 gal/min at any angle. That is the law of conservation of mass. If you are calculating a force then I will agree on you.
@@nicoj.8242 He did take into account the slope of the roof by eliminating from his calculation. He used the horizontal distance from the peak of the roof to the gutter. This is a straight distance between the center ridge of the house and the outside edge. If he had used the slope distance along the face of the roof he would be incorrectly increasing the area of collection as the rain typically comes straight down and not perpendicular to the face of the roof. Once the rain hits the roof, and then collects in the gutter, the flow rate is the same no matter what the roof pitch is. The only difference between a steeply pitched roof and a shallow pitched roof would be the time it takes for the entire roof to drain into the gutter. A steeper roof would initially get the water into the gutter faster, but once there, it's flow is the same, provided both roofs have the same horizontal area.

WOW! I wasn't expecting how entertaining and captivating this was, and I definitely wasn't expecting what a quality video/editing job it was! Great work!
This video reaches the perfect balance between funny and informative. Great job ! I may recommend it to my Freshmen Engineering students: it makes for a great exploration of energetic orders of magnitude (and why hydro-electric power requires such gigantic infrastructures !). Thank you for this excellent job !
Thanks so much! Part of me wanted to dive into the math a little deeper but an engineering class would be the perfect place for that. You might also look at my video on filling a tire with a garden hose. It's great for engineering students, especially learning about absolute and gauge pressure in an automotive context.
@@QuintBUILDs Yeah, I saw it too. As a matter of fact, it was the first video of yours that I saw, which made me want to check all the others ! But I felt that something was missing from that other one (or maybe I missed it): I do not recall hearing you cite the value of the base water pressure out of the faucet. Granted, though, depending on how your chained valves work (I am not sure I got that clearly), it may be possible to exceed that base water pressure via the accumulation of bottles on a single rail. Anyway, I like the way you think, here, and I like that you put efforts into estimating orders of magnitude. That is where engineering starts getting beyond mere tinkering. I will definitely direct my students to your channel.
I don't remember if I included it or not, maybe a quick view of the pressure gauge when I turned on the water? For anyone interested it was much higher than expected, 80 psi!
@@QuintBUILDs That's more than 5 bars ! This is indeed very high ! Don't you get frequent leaks, or premature fatigue of your appliances ? Most plumbery equipments are meant to run at 3 bars or so, not too much more.
This guy does such a great job, doesn't he? He makes the feeling of "Bored" seem non-existant as he informs about a bit of stuff that could actually be useful.... Now to impliment that same system to our school system.... Without failure like the last three times.
Idea to reduce loses: 1. Have eventual nozzle positioned at the base of the make shift reservoir, so water is shooting downwards, as opposed to sideways.
I’m imagining that to make a massive difference, but when you think about the maths, it only adds a tiny bit more to ‘h’ in the equation. There’s no losses except wind resistance to that stream of water going sideways.
When you waste your money you will never have much , this man has never smoked , drugged or drank booze on a daily basis and it shows , great job bud , i envy your kids for they will be top of their class with great skills , great job
I came up with this idea when I was little. I figured that people weren't doing it because it wasn't enough energy. It's really nice to see someone trying it to see if it's possible :)
the frame transition from actual footage to a paper with drawings fading in to substitute the movie and brig the spectator to the calculus is very smart! That's how we see someone think even the smallest details!
This is one of the most entertaining videos that I have seen ever, because you are using the right mix of theory and practice while iterating to improve it.
@FalconerPhoto Having performed the request, the possibility that the coat is simply off color and the top small person is using a voice modulator seems plausible.
Hi! Your video is so inspirational! Thank you very much! It is art! So many ways to express art and give value to everything! A sculpture made like bamboo scaffolding and an ever flowing fountain with many of your wonderful inventions. It is energizing art!
@@QuintBUILDs Hi! Thank you for your answer! What I meant by ever-flowing fountain is a non-stop flowing fountain ( less poetic to say ). A ram pump is also an interesting tool. Bamboo construction are so beautiful! Many artist use them to build beautiful water fountains! Kinetic sculptures, architecture, so much art!
Would efficiency come from flipping the wheel? Water splashes are directed up instead of down; I think this would also result in a small loss of energy.
How does that makes sense? Droplets will have the same energy regardless of which direction they deflected to. If you let them fly long enough they will eventually trade their potential energy for kinetic, but at the moment of impact it has no effect.
@@AYoungdude Exactly, utilising a very small amount of gravitational energy to add to the total potential energy, technically it would help, but notably, I'm not too sure
Mi 28 the closer you get to a deflection of 180 degrees to the input angle the better. So ideally it’s straight back at the jet, but obviously they’d hit each other so in practice the best workable angle is about 165 degrees. The direction does matter, further from 180 means less power 😊
An "American " that just said metric is way easier than imperial. Lmfao. (Australia here) i love it! Not to denote from the fact very cool vid brother. Been considering trying a rather different but similar thing myself. Cheers to you sir.
LOL, most American's think imperial is great, until they try to do something useful with it! That was the joke back in engineering school, anytime the prof gave a problem in inches and pounds you just converted to metric, solved it, then converted the answer back. Seriously! And thanks for the encouraging comments, all of them...
@@QuintBUILDs there's a guy on you tube, angry ram i think he goes by. Does some rather clever stuff with off grid power using Pelton wheels. Not exactly what you are trying but potentially some good brain food for someone such as yourself. Or maybe way to simple, just incase 😉
I've seen Angry Ram's thumbnail of his washing machine pelton setup but never watched until now. Very cool. I have access to property with a creek like that, not enough head for pelton but definitely worth experimenting with.
@@QuintBUILDs you tube just gave me another, wasn't searching. ..joe malovich, round turbine housing an improvement? The vid is called. Sry incase this is just annoying now. More brain food 😉
The hero we didn't know we needed. I've been looking into making a system like this to go with solar for a few years now. Thanks for the information! :)
@@osmick15 at least they save themselves all the stuff he had to find out himself and can right into building theirs for I don't know, a rain indicator LED
I haven’t even watched the video yet, but based on the feedback from the comments, you sound like an excellent teacher, I’m looking forward to diving into the video! Learning what you have to teach and also how I can be a better teacher too!
I am watching this at 2:30 am in norway, Never know about this channel and i kinda love it :D I wish i had you as a teacher when i studied welding, Keep up the great work
Man, I had this idea 5 years ago when I was still studying as a mechanical engineer. My professors didn't like the concept and said it's not possible. I wish I had you as my professor. Continue the great work!
I've seen people say that too, that it's impossible. C'mon, it's possible, just not practical! I think it's a great exercise for engineering students myself.
There are so many lessons in this. Lubrication, rolling resistance, dynamic bearing loading, flow rates, work, force logic, mechanical loss, I have lost count of all them. Great video.
one of the most important flaw in this design is that stuff that flows down your tube causing it to clog. you may need to install a filter at top but doing that may decrease your flow, although necessary. have you consider cascading waterwheels to get as much power out of it?
We could put this on houses in heavily rainy regions so that when it rains the rain can help power the lights. Combined with solar and omnidirection wind turbines your house could be mostly powered by renewable energy on location.
GREAT educational video on power production. Most people don't have a clue what it takes to generate real, usable amounts of power.......but instead will watch videos where some guy connects a electric motor (with no electric input) to a generator and has a ridiculous claim of 'free' energy.
Ah yes! The algorithm did it again. Here I am, 2 AM. Trying to sleep, yet stuck so deep. I don't know this channel, the video's cool. Must go now, tomorrow there's school.
Awesome job! I, respectfully, disagree with a couple of conclusions you had. First, you should use pulleys and a belt instead of gears, since they don't operate well at high RPMs. Second, you shouldn't decrease the diameter of the turbine - you should increase it. The more you increase, the lower power (or water flow) needed at the tips to create higher RPMs at the center.
You didn’t take the angle of the roof in to consideration and by the looks of things it’s quite steep meaning the area is much less. Great video tho keep it up.
I rarely comment on videos and apologies for the essay ahead of time. I wanted to say how much joy this video brought me, I’m hoping to apply to do a PHD in physics sometime next year but have had major burnout for the past little while with covid restricting all in person lab and experimental work. I’ve been doing what I can from my home lab but this video really reminded me of what first got me into engineering and then physics! I’m a specialist in STEM in no small part due to not being able to clearly communicate wishy washy things like emotions so for lack of better description this video made me warm and fuzzy and had me cheering along like a kid! You have something really special here that truly captures the essence of experimentation and development. For what it’s worth thank you for making such great content!
Hahaha YES! I had a problem in my fluid mechanics class that was this EXACT problem! With our given parameters we could only power 7 lightbulbs (small LED bulbs if I remember), but in Oregon you could probably get a decent amount of electricity.
@@michaelvalmo Oregon: n. A US state known for heavy rainfall and hipsters. "I want to get out on my fixie, but all this Oregon rain is keeping me inside"
Yeah and then he will have to pay the carpenter $1000 for restoring the house wall that has rottened because of water splashing all over the wall. Not so bright!
A great video and a great idea for the rainy UK. I suppose I 'd need to measure the flow rate from the garden hose but looks like a nice project to try at home.
This is cool, sir. Yesterday I thought of the same thing, since it's been raining here for more than a month and no sunlight to recharge; though theoretically I did it in a different manner. While searching for related ideas, I came across with your video.
Thx for sharing. What a great premise for a project. Reasonable expectation of generator eta should be near 85%. Now, lets derate due to small size of the system, so, you should still expect around a 70% eta. I loved that you did the math beforehand so you had a good idea of what to expect from the system overall. Good job. Don't focus on the voltage that can be adjusted with windings and or DC-DC converters. Focus on the transducer eta first the rest will follow. Again thx for sharing.
The sheer ridiculousness of this project is hilarious! He's got at least 10k worth of machining equipment to generate such a small amount of power! Great for explaining physics to the kids though!
10k for sure not enough. 3D print, milling and turning lathe, drilling machine, plasma cutter, welding machine. Raw materials... Unbelievable. None of it simply procurable in home depot or whatever you have there in the US. Industry grade tools.
@@darkcoeficient This is an insanely good comment. So many people complain about rich vs poor without having a single clue how much the rich really do for everyone else. I myself just build the house, it's the rich that give me the ability to even make money.
Very good way of explaining the substance. Suitable to get better attention from high school kids... The idea is not as frivolous as you may think. In 1999 I submitted an invention about it to the patenting department of the University of Ghent in Belgium. The system is considerably different from yours, so don't worry, you're not having any legal issues with this video :)) So far the patent has not resulted in a commercial product, but then in 1999 green energy needs were not as big as today...
Seriously? Somebody's *accent* is so annoying you'd consider suicide? Wow, what would you do if there's a dripping faucet you can't turn off, set fire to the whole neighborhood?
I had the same thought. Need to use the 'projected area'. Although the formula depends how Ø is specified. If Ø is the angle from the horizontal (which makes more intuitive sense to me because, then, the angle is zero for a flat roof and has a high value for a steep roof), *cos(Ø) would be the way to go. I know that you know that already. Just being rigorous 🙂. Now, on the subject of rain, do the windshield washers have to work harder, if the car is moving versus stationary?
Looked up rain as renewable energy, this was the first video I clicked on and the first sentence resonated as I live in Oregon, and the rain was absurd this last week.
Me: intuitively, my sense is this is going to be a complete waste of time. Quint: I need to know how much energy this is going to generate, because if it’s not enough, I’m not going to waste my time building it. Math: it will generate 1W. Quint: I’m going to go ahead and waste a lot of time on this. Me: intuition confirmed. Am I going to watch part 2? Yes.
It's part of engineering. Knowing what doesn't work but still engineer it. Unfortunately that doesn't happen with science nowadays as "scientists" don't even understand how to apply for the scientific method or experiments and and so on...
Fascinating, I was just sitting here in the UK and currently isolated, due to me and family getting Covid, when I started thinking about getting small amounts of power back for charging batteries, etc Solar and wind power are the usual go toos in the UK for domestic, but Rain Water sprung to mind as something that generally is only collected in large hydroelectric power stations and not collected domestically. A quick search brought me to you and I agree that it is potentially a great idea. If I had space and money, I would install a large tank to hold rainwater in the ground before it overflows if not used to the main drainage system and then use solar and wind to pump up to a high-level tank before dropping back down into the lower tank again for re-use. Unfortunately, the UK gives more rain than we get solar power Lol I believe that in small towns and small cities, water could be collected this way and re-used before it is eventually processed for drinking again or pumped back into the river :) Look forward to watching part two now to see how you did :)
the world would have more physicists, engineers and mathematicians if guys like these taught in public schools
Unfortunately there are more teachers for gender studies and other liberal arts.

I may recommend it to my Freshmen Engineering students: it makes for a great exploration of energetic orders of magnitude (and why hydro-electric power requires such gigantic infrastructures !). Thank you for this excellent job !
Thanks so much! Part of me wanted to dive into the math a little deeper but an engineering class would be the perfect place for that. You might also look at my video on filling a tire with a garden hose. It's great for engineering students, especially learning about absolute and gauge pressure in an automotive context.
@@QuintBUILDs Yeah, I saw it too. As a matter of fact, it was the first video of yours that I saw, which made me want to check all the others ! But I felt that something was missing from that other one (or maybe I missed it): I do not recall hearing you cite the value of the base water pressure out of the faucet. Granted, though, depending on how your chained valves work (I am not sure I got that clearly), it may be possible to exceed that base water pressure via the accumulation of bottles on a single rail.
Anyway, I like the way you think, here, and I like that you put efforts into estimating orders of magnitude. That is where engineering starts getting beyond mere tinkering. I will definitely direct my students to your channel.
I don't remember if I included it or not, maybe a quick view of the pressure gauge when I turned on the water? For anyone interested it was much higher than expected, 80 psi!
@@QuintBUILDs That's more than 5 bars ! This is indeed very high ! Don't you get frequent leaks, or premature fatigue of your appliances ? Most plumbery equipments are meant to run at 3 bars or so, not too much more.
This guy does such a great job, doesn't he? He makes the feeling of "Bored" seem non-existant as he informs about a bit of stuff that could actually be useful.... Now to impliment that same system to our school system.... Without failure like the last three times.
bro i am impressed that you're calculating all this stuff, i'm the type to just wing it and pray to god it works
Idea to reduce loses:
1. Have eventual nozzle positioned at the base of the make shift reservoir, so water is shooting downwards, as opposed to sideways.
meelokun exactly what I was thinking.
I’m imagining that to make a massive difference, but when you think about the maths, it only adds a tiny bit more to ‘h’ in the equation. There’s no losses except wind resistance to that stream of water going sideways.
Harry C. Well it’s going with gravity more and not fighting it so I think it would help
For that to work, you would also need to implement some sort of filter to prevent clogging.
@@blazethefaith A filter would still clog. Perhaps another approach would be to design a means for debris to simply flow past.
Really enjoyed this - great mixture of theory, production quality and madness.

Thats what she said
I came up with this idea when I was little. I figured that people weren't doing it because it wasn't enough energy. It's really nice to see someone trying it to see if it's possible :)
You were right to not pursue it. Great for learning but simply not viable.
Great to see a real Engineer who can think systematically with pragmatic approach to solve a problem. Kudos to your effort. Subscribed.
Envious of this guy's shop equiment . . . specially that 3D printer. Way cool.
I have wondered about this so often, awesome to see somebody actually try it out. Also, your drawings are absolutely amazing.
Thanks! Funny how so many people have had the thought. Glad you like the drawings, I tried that first one and loved it so much I can't stop!
I have too! I wondered if I put multiple turbines down the gutter would it generate much power. Imagine if you could do this on major pipes.
Power output or not, adding a waterwheel to a rain gutter is always fun.
the frame transition from actual footage to a paper with drawings fading in to substitute the movie and brig the spectator to the calculus is very smart! That's how we see someone think even the smallest details!

Engineer here, very excited that UA-cam suggested me your channel 😎 Your explanations are very nice!
This is one of the most entertaining videos that I have seen ever, because you are using the right mix of theory and practice while iterating to improve it.
Dude! I don't know if I knew it until you wrote it... THAT'S my goal. Wow. Going to steal that if you don't mind.
I second this. That's exactly what makes this so good.
This is one of the cleanest videos I've seen on UA-cam so far. Keep up the good work mate!
This man is but two small persons

It looks like hes wearing a medical/doctor/chemist lab coat. Just it's black and not white like they usually are.
@FalconerPhoto Having performed the request, the possibility that the coat is simply off color and the top small person is using a voice modulator seems plausible.

Hi! Your video is so inspirational! Thank you very much! It is art! So many ways to express art and give value to everything! A sculpture made like bamboo scaffolding and an ever flowing fountain with many of your wonderful inventions. It is energizing art!
Thanks so much! The videos really are more art than I ever would have expected.
@@QuintBUILDs Hi! Thank you for your answer! What I meant by ever-flowing fountain is a non-stop flowing fountain ( less poetic to say ). A ram pump is also an interesting tool. Bamboo construction are so beautiful! Many artist use them to build beautiful water fountains! Kinetic sculptures, architecture, so much art!
Would efficiency come from flipping the wheel? Water splashes are directed up instead of down; I think this would also result in a small loss of energy.
hour9 I was thinking that too, but I guess it wouldn’t have too much of an effect
How does that makes sense? Droplets will have the same energy regardless of which direction they deflected to. If you let them fly long enough they will eventually trade their potential energy for kinetic, but at the moment of impact it has no effect.
@@michaelbuckers the cups would "carry" the water down instead of being just pushed away by the water
@@AYoungdude Exactly, utilising a very small amount of gravitational energy to add to the total potential energy, technically it would help, but notably, I'm not too sure
Mi 28 the closer you get to a deflection of 180 degrees to the input angle the better. So ideally it’s straight back at the jet, but obviously they’d hit each other so in practice the best workable angle is about 165 degrees. The direction does matter, further from 180 means less power 😊
An "American " that just said metric is way easier than imperial. Lmfao. (Australia here) i love it! Not to denote from the fact very cool vid brother. Been considering trying a rather different but similar thing myself. Cheers to you sir.
LOL, most American's think imperial is great, until they try to do something useful with it! That was the joke back in engineering school, anytime the prof gave a problem in inches and pounds you just converted to metric, solved it, then converted the answer back. Seriously! And thanks for the encouraging comments, all of them...
@@QuintBUILDs there's a guy on you tube, angry ram i think he goes by. Does some rather clever stuff with off grid power using Pelton wheels. Not exactly what you are trying but potentially some good brain food for someone such as yourself. Or maybe way to simple, just incase 😉
Oo, sry quint, replied to the wrong mail but still. Haha. ☺
I've seen Angry Ram's thumbnail of his washing machine pelton setup but never watched until now. Very cool. I have access to property with a creek like that, not enough head for pelton but definitely worth experimenting with.
@@QuintBUILDs you tube just gave me another, wasn't searching. ..joe malovich, round turbine housing an improvement? The vid is called. Sry incase this is just annoying now. More brain food 😉
Awesome bit of concept engineering. Should be mandatory viewing in every high school. Thx!
The peloton wheel was created in Rjukan. Rjukan is a little town in Norway, I live about 45min from there.
If we Teach this stuff to school students , you would see a big change, a good change
"When will I ever use this in the real world?" well right here
@@FalconWing1813 Hmm.... Us with our American school system could probably impliment that within one thousand years. That quick enough?
I love how excited you are to see it all come together
The hero we didn't know we needed. I've been looking into making a system like this to go with solar for a few years now. Thanks for the information! :)
Doing engineering calculations should only be ever done in metric. Even when you’re stuck in 12th century saxony way of thinking . Hi from England
😂
Greg Jaskiewicz Lets not get started on English measurement!
David Canady world measurement. As in the whole world except the US and North Korea.
@@johngray1972 even North Korea is using the metric system, so it is basically only the shithole countries left to use the imperial system.(:
Even worse here in England, where we use both. We measure fuel economy in miles per gallon yet buy fuel in litres.
When an engineer is in quarantine too long.

I love it when he says roof. It’s the best.
Like a crossover between Matthias Wandel and Smarter Every Day... Great video!
"This is waay easier in metrics"
thx youtube for recommending this to me.
I haven’t even watched the video yet, but based on the feedback from the comments, you sound like an excellent teacher, I’m looking forward to diving into the video! Learning what you have to teach and also how I can be a better teacher too!
I am watching this at 2:30 am in norway,
Never know about this channel and i kinda love it :D
I wish i had you as a teacher when i studied welding,
Keep up the great work
If this is the apocalypse, I wanna be in this guy's group.
Man, I had this idea 5 years ago when I was still studying as a mechanical engineer. My professors didn't like the concept and said it's not possible. I wish I had you as my professor. Continue the great work!
I've seen people say that too, that it's impossible. C'mon, it's possible, just not practical! I think it's a great exercise for engineering students myself.
There are so many lessons in this. Lubrication, rolling resistance, dynamic bearing loading, flow rates, work, force logic, mechanical loss, I have lost count of all them. Great video.
one of the most important flaw in this design is that stuff that flows down your tube causing it to clog. you may need to install a filter at top but doing that may decrease your flow, although necessary. have you consider cascading waterwheels to get as much power out of it?
Most of us can’t even be bothered to clean our gutters.
I've genuinely always wanted to try this - but aware it's ultimately pointless. Nice to see someone else working through this idea though!
Bingo. Figured I'd get it done so everyone can see!
there is hope for humankind, thanks to You
WOW, one of the best "hands on" science shows I have ever seen! Beats even most professional tv shows. Thank you.

I look forward to more videos.
We could put this on houses in heavily rainy regions so that when it rains the rain can help power the lights. Combined with solar and omnidirection wind turbines your house could be mostly powered by renewable energy on location.
Not really tho
Maybe if you were off grid and wanted to use stored water energy at night for a string of leds because you didn’t get a battery.
My 4 year old, a probable future engineer, loves your videos!
You are brilliant. The joy in your face when you've got it to work is outstanding. Keep up the good work.
If I lived in a place with so much rain that I would consider converting it to electricity, the first thing I would do is MOVE OUT
Having fresh water is nice.
Imagine putting this in drainage system of multi story buildings.

Yo Mama dang buddy’s got some issues
@Yo Mama you know you can "store" electricity right?
GREAT educational video on power production. Most people don't have a clue what it takes to generate real, usable amounts of power.......but instead will watch videos where some guy connects a electric motor (with no electric input) to a generator and has a ridiculous claim of 'free' energy.
Ah yes! The algorithm did it again.
Here I am, 2 AM.
Trying to sleep, yet stuck so deep.
I don't know this channel, the video's cool.
Must go now, tomorrow there's school.
Awesome job! I, respectfully, disagree with a couple of conclusions you had. First, you should use pulleys and a belt instead of gears, since they don't operate well at high RPMs. Second, you shouldn't decrease the diameter of the turbine - you should increase it. The more you increase, the lower power (or water flow) needed at the tips to create higher RPMs at the center.
You didn’t take the angle of the roof in to consideration and by the looks of things it’s quite steep meaning the area is much less. Great video tho keep it up.
Exactly. He needs to figure out the horizontal length of that right triangle rather than using the sloped lenght. Super easy.
Thank goodness someone said it!
You guys are right but.... he did say horizontal distance. Only once though. 0:27
Also, in his diagram of his roof you can see the dimension is horizontal, not parallel to to the roof, he did take the angle into account.
Wind direction can either negate that problem or exacerbate it.
I rarely comment on videos and apologies for the essay ahead of time.
I wanted to say how much joy this video brought me, I’m hoping to apply to do a PHD in physics sometime next year but have had major burnout for the past little while with covid restricting all in person lab and experimental work.
I’ve been doing what I can from my home lab but this video really reminded me of what first got me into engineering and then physics!
I’m a specialist in STEM in no small part due to not being able to clearly communicate wishy washy things like emotions so for lack of better description this video made me warm and fuzzy and had me cheering along like a kid!
You have something really special here that truly captures the essence of experimentation and development.
For what it’s worth thank you for making such great content!
Hahaha YES! I had a problem in my fluid mechanics class that was this EXACT problem! With our given parameters we could only power 7 lightbulbs (small LED bulbs if I remember), but in Oregon you could probably get a decent amount of electricity.

A great video and a great idea for the rainy UK. I suppose I 'd need to measure the flow rate from the garden hose but looks like a nice project to try at home.
This is cool, sir. Yesterday I thought of the same thing, since it's been raining here for more than a month and no sunlight to recharge; though theoretically I did it in a different manner. While searching for related ideas, I came across with your video.
no idea why the youtube algorithm showed me this but i loved it
“Rather than building it from scratch, I’m just printing it on my 3D printer 😏” - says casually
Oh my gosh this video is amazing to watch
Thx for sharing. What a great premise for a project.
Reasonable expectation of generator eta should be near 85%. Now, lets derate due to small size of the system, so, you should still expect around a 70% eta.
I loved that you did the math beforehand so you had a good idea of what to expect from the system overall. Good job.
Don't focus on the voltage that can be adjusted with windings and or DC-DC converters. Focus on the transducer eta first the rest will follow.
Again thx for sharing.
The sheer ridiculousness of this project is hilarious! He's got at least 10k worth of machining equipment to generate such a small amount of power! Great for explaining physics to the kids though!
You stole my comment.
Well that just goes to show how much resources are spent to obtain something back. Even more appreciation for what we get.
10k for sure not enough. 3D print, milling and turning lathe, drilling machine, plasma cutter, welding machine. Raw materials... Unbelievable. None of it simply procurable in home depot or whatever you have there in the US. Industry grade tools.

Very good way of explaining the substance. Suitable to get better attention from high school kids... The idea is not as frivolous as you may think. In 1999 I submitted an invention about it to the patenting department of the University of Ghent in Belgium. The system is considerably different from yours, so don't worry, you're not having any legal issues with this video :)) So far the patent has not resulted in a commercial product, but then in 1999 green energy needs were not as big as today...
If he says rouf one more time I'm going to end it all
its very painful
I was thinking the exact same thing... 11 seconds into the video and I could tell its gonna be annoying. Do all americans call it rouf

-*sin(Ø) for the area of the roof that intersects the rainwater
Had to scroll way too far down for this.
I had the same thought. Need to use the 'projected area'. Although the formula depends how Ø is specified. If Ø is the angle from the horizontal (which makes more intuitive sense to me because, then, the angle is zero for a flat roof and has a high value for a steep roof), *cos(Ø) would be the way to go.
I know that you know that already. Just being rigorous 🙂.
Now, on the subject of rain, do the windshield washers have to work harder, if the car is moving versus stationary?
@@kshred3043 the rain falls at an angle equal to the rake of the roof (ruff)👍😂

Looked up rain as renewable energy, this was the first video I clicked on and the first sentence resonated as I live in Oregon, and the rain was absurd this last week.
6:28: Thanks for turning my lights off....
Me: intuitively, my sense is this is going to be a complete waste of time.
Quint: I need to know how much energy this is going to generate, because if it’s not enough, I’m not going to waste my time building it.
Math: it will generate 1W.
Quint: I’m going to go ahead and waste a lot of time on this.
Me: intuition confirmed.
Am I going to watch part 2? Yes.
Tikkun It would generate almost nothing. But it would be neat.
You forgot though, the video has generated over 1million views, which results in monetary gain that he didn't have in his equation at all. ;)
It's part of engineering. Knowing what doesn't work but still engineer it.
Unfortunately that doesn't happen with science nowadays as "scientists" don't even understand how to apply for the scientific method or experiments and and so on...

We had to do a shark tank project at school and my team came up with this for our project before this video. Life’s crazy
Fascinating, I was just sitting here in the UK and currently isolated, due to me and family getting Covid, when I started thinking about getting small amounts of power back for charging batteries, etc Solar and wind power are the usual go toos in the UK for domestic, but Rain Water sprung to mind as something that generally is only collected in large hydroelectric power stations and not collected domestically. A quick search brought me to you and I agree that it is potentially a great idea. If I had space and money, I would install a large tank to hold rainwater in the ground before it overflows if not used to the main drainage system and then use solar and wind to pump up to a high-level tank before dropping back down into the lower tank again for re-use. Unfortunately, the UK gives more rain than we get solar power Lol I believe that in small towns and small cities, water could be collected this way and re-used before it is eventually processed for drinking again or pumped back into the river :) Look forward to watching part two now to see how you did :)
