You need to put the turbines as low as possible otherwise you basically waste all the potential energy stored in the water. If you place the turbines on top of your dam, it does not make any sense to build the dam in a first place. In your case the power output is the same as turbine in the river, which is basically none. Also the water from the overflow cannot just fall down to the base of the dam, it will destroy the dam in a few weeks.
While many of us here knows better and can do better theoretically, this guy just practically showed a functional example even when it's not perfect. Maybe he scarcely graduated from an urban school and many here studied in Cambridge. Let's appreciate his work. 👌
I think he could do much better than us (well many anyway, I know I haven't studied the subject but there's probably lots of engineers here) if he was building one of these as a serious power generation setup. I think these are like those RC drones made to look like spaceships or historical planes, interesting to build but practicality is secondary. Look at those LEDs placed like they're lining a road, I think he put a miniature control station there too, I think those are the main goal.
@@EvonixTheGreatest I think you are right but the videos maintain a pretense like this isn't just smoke and mirrors. It parallels those "primitive technology" channels who use heavy equipment off camera in that the presentation is (whether intentional or not in this case) disingenuous.
If you have to redo it, place the turbines in the bottom of the wall and have the valve behind the turbines. You can try to build a smooth nuzzle to increase the speed of the water so that the genarator can turn faster. You should also use fins and a curved wall (curvature into the Water side of the dam) to support the structure. You also could use gears to increase the speed and with that the voltage of the generator
was gonna comment this but seen you already did, it would prob produce 50% more if they were just before the bend at the bottom, thats how they used to make high pressure water for the mines etc, pipe starts up top 4m wide and by the time its at the bottom its a 5 inch pipe with pressure that would peel your skin off
I think the key here is that he likes building things and could care less about the power output. He never shows batteries, inverter or power output. He did a good job and gets lots of views. It is fun for him.
I love that man's creative genius that he has put to practical use,no matter of how he could have done it better,, the fact is this man rather than waisting his time put his God given brain 🧠 to work and put together a device that actually makes electricity,, and I agree with that person that mentioned that it would be a great place for school kids to come and visit to see what a person can do when they apply themselves and not wait for some sort of entitlement,,, good job there buddy,,God bless you and thank you for that video 😊
Looks like a really fun project. My general improvements would be to make the brick wall curve into the water for extra strength and lower the turbines
Despite whatever "flaws" in the Physics, demonstrates clearly: Where there is a WILL, there IS a WAY. Human INDUSTRY and attention to detail at its finest, and a righteous sense of HUMOR. 👍👍👍 I can hear the voices murmuring in the ethers: I wish I'd thought of that!
LOL this is not efficien solution at all :D you need transfer waret in pipe from the hill down to you micro hydro turbine, to make effecient power source. This is to make money on youtube, not to make energy. This is art, not engineering.
While it may not be the most effective or efficient damn, it’s still a good looking and working damn! Thank you for sharing, it’s cool seeing people figure out how to design and make things like this

Do yourself a favour and watch some actually qualified people do this, especially some structural engineering because I can’t see this thing lasting for more than a couple of weeks
I’ve never built anything like this, but I could see many very weak places, or just plain flaws in this structure. The biggest thing I can see missing is that there is no structural reinforcement of any kind. No wire, grid, bars, beams, … nothing. With that said, I acknowledge the craftsmanship of this thing. It’s just that it’s more of a miniature model than a facility meant to last.
@@xxmlgxx2151 I didn’t think there was any point in mentioning it honestly, but while we’re at it, the turbines will definitely rust, too heavy to be efficient and are practically at the water level so don’t get any of the speed the water gets while falling. Also absolutely zero safety when welding, if he holds it with his bare hands and accidentally electrocutes himself he’d be very dead.
It’s always great to see design imagination at work. It shows there are many different solutions to the same problem: how to generate power from water flow. I take the comment about having turbines lower down but that would demand a different turbine design (perhaps a Pelton Wheel Turbine). However it’s associated generator would have to be kept dry and that would be difficult, placed at the base of the down tubes. The good thing about the design shown is that the generators are well above the water. Also, if the turbines fit the down tubes well enough and the water flow through them remains coherent (laminar flow) then the weight of water BELOW the turbine will also energise it. In other words, the turbine will be ‘sucked’ from below and ‘blown’ from above. For me the question is ‘What diameter of pipe will produce laminar flow both above and below the turbine?’ This vid is a great contribution towards Appropriate Technology also known as Alternative Technology. Brilliant video. 🙏🙏🙏
@@Tran-Chien I will carry on thinking about this design. I suspect that long screw shaped turbines with a very coarse pitch would preserve the laminar flow of water as it passes down the down pipes. What I am picturing is a turbine similar to a worm gear but, as I say, with a very coarse thread of perhaps just two turns of the thread from top to bottom. It might be good if the spiral was cut with the profile similar to an ‘acme thread’ profile. An acme thread is like a ‘square thread’ but with a more angled ‘shoulder’ to the thread. Why? This profile would force a small percentage of the water flow into the small gap (clearance) between the turbine screw an the wall of the pipes. This would prevent direct contact between the turbine and the inside of the down pipe it was sitting in. This would a) massively reduce friction, b) minimise wear, maximising the life of the turbine c) ‘centre’ the turbine within the down pipe, stabilising it. This would eliminate vibrations. The ‘elongated worm gear turbine’ would enable that idea I mentioned that with optimal design, the turbines would be ‘sucked’ from below as well as ‘blown’ from above. Another appealing aspect of your design is that it is made from available components. As for the ‘elongated worm gear turbine’ this could be made in hardwood and turned in a screw-cutting lathe. Alternatively it could be sourced as a spare part Archimedes Screw as found in domestic kitchen meat grinders. Ideally the thread should have a longer pitch than the typical meat grinder screw, but I think a meat grinder screw would help with preserving laminar flow. Finally, the longer the pitch of the screw turbine, a) the slower its rotation and b) the higher its torque. High torque and low RPM would enable any direct coupled generator to work at a corresponding low RPM, reducing bearing wear. If the generator is designed to work optimally at high RPM there could be a gearbox between the turbine and the generator. The scope for development in your system is very high. As I see it, this is an alternative technology suited ideally to small scale power generation with perhaps one system supplying power to a maximum of about three households. The design could be replicated many thousands of times within the skill range and parts available almost anywhere in the world where water flow with a ‘low head’ of about 1-2 metres can be arranged. I admire your work which I think could have a very widespread beneficial impact. I hope you can find collaborators who know how to calculate the relationship between fluid dynamics, turbine design, generator RPM and predicted generator output. Alternatively you can optimise your system by trial and error. It only has to be good enough. It has been said ‘Don’t let Perfection be the Enemy of the Good!’
when you said something about a vacuum effect, I assume a tapered end would work if the math is done just right. Too much water, it doesnt work, too little water, it doesnt work. You know how that goes :p
@@EvilNeonETC That sounds like a good idea. Thinking about it a taper might make the water accelerate although, as the mass of water would reduce towards the bottom end, the effect of gravity (the ‘suck’) might be less too. In power station design, the high pressure end of the turbine (first stage) is smaller than the low pressure end of the turbine. These turbines increase in diameter in three steps, I think to extract as much kinetic energy from the steam as possible. However water behaves very differently to steam, being uncompressable. As laminar flow in water is our objective here, I think having a reducing taper could be a good idea 👍
@@EvilNeonETC Also, further to my last comment the amount of energy in the water is less at the top and potentially more at the bottom so tapering that is the reverse of a steam turbine makes good sense. I’m thinking that the rate of transfer of energy from water flow to turbine should be the same along its length… so yes 👍 Steam Turbine blades are also angled differently at each stage so maybe the pitch of the turbine blade should also vary along its length 🤔
This dam looks really cool and took a lot of effort to build for sure. Although I am having some second thoughts on the design decisions. The wall of the dam is not built into any recess in the wall ant it is also not curved at all like all full size dam walls are. This usually helps to withstand high water pressures. Now, the video shows that the dam apparently is strong enough as is, but still - it could be much stronger. The wall is also additionally weakened by the channels alongside the channel walls that support the dam. Now, I am not an expert, but maybe this dam won't withstand the force of the river carrying high waters as is has been designed right now.
@@randybobandy9828 Yeah you're right, but it's also much thinner and not built out of concrete, like a full size dam would be. It is a scaled model, which is true for the amount of water it is holding back but also for the structure itself.
I’ve got a limited amount a highly limited amount of construction experience and no I agree the wall won’t last there’s no concrete stopping erosion on the sides of those u shapes to redirect water the wall isn’t thick enough to hold that kind of weight back for a high amount of time the designs cool he just didn’t put enough meat to the damn and redirects
As you are getting better at this all (well, you were always GREAT!) you may want to start adding a voltage meter to show how much power your future damns can make.
beautiful, wonderful... if you put the propellers in the bottom of the well, and control the flow of the vertical tube at its base, you can have much more energy.
Very interesting to watch thanks CG. It just goes to show how much free power is produced from running water. Also enjoyed hearing the sounds of the speeded up footage and it's nice that the builders dog was part of the show.
The spillways may be insufficient to prevent degradation of surrounding dirt wall under torrential rains. I recommend concreting the walls as well using wire mesh backing.
I was surprised this one held the weight of the water being so tall with no support on the down stream side . Which he has put more engineering into others I've watched. But I guess he has the minimum engineering down to a science by now , knowing what will last long enough , then be easier to demolish and remove . The engineering and investment would be out the box crazy to make it last even 1 year through the rainy season I bet. And I think all you could hope to generate electricity wise probably wouldn't even equal a small 1000 watt gas powered generator that you would get 5 years of on demand electricity out of for $2-300 dollars . And then he probably doesn't even have the water rights to divert that much water a year ?
You would generate more power with bigger motors and have the turbine impeller at the bottom of the pipes. The height of the pipes will have a lot of weight and pressure of the water hitting the blades therefore able to run a much bigger motor. Water pressure is usually about 4lb per square inch and multiplies a lot more the deeper it is.👍❤️💛💚
Water pressure is ~0.5 PSI for every foot of head (depth from free surface at the top to the bottom). You have about 4 feet of head, so will have about 2 psi at the bottom and 0 psi at the top. I would also arch the dam upstream as there was no steel reinforcement to counter the bending moment on the front face of the dam, so am concerned about the dam failing at the bottom. But since this is just a model, more about aesthetics than production, I think it looks good.
Kaplan turbines work on flow. Bernoulli's principal says flow in a pipe remains constant. So that would not matter much. Francis tubines require more pressure but much less flow. They would benefit from being placed lower in the penstock, but that is not what he built here.
You could see water penetrating the concrete at the top area near the turbines anyway. I'm guessing the dam didn't function for more than a day and stayed standing for less than a week. Channels like this make their project and then abandon it and go on to the next, they don't maintain any of the projects they build.
Не нашёл коменты на русском и решил написать сам ). Поздравляю! Вы постепенно увеличиваете высоту плотин)) и делаете уже почти высоконапорные гидротурбины )))
The previous remarks do go to the betterment of the design. My experience with water at this scale points to erosion eventually destroying such beautiful work. As a model, these designs create enormous possibilities for new projects. Always remember that the water at the base weighs more than at the surface thus the pressure will eventually seep under the barrage's footings. Another application might adopt a water wheel on axle to drive the turbine on a dry land position. Regardless, we see brains at work here with different designs. Strength is the priority if the project is to survive. A small ditch of this sort is not to be misjudged.
What a fun project! Ofcourse your friend had to try walking accross the top of the dam! Priceless!! Thanks for sharing! It would be so helpful if the critics could post a link to their video here to show the rest of us how they solved these mistakes on their own builds.
This seems like a village paddy field somewhere in Asia. Villagers don't have separate water supply and walls between their fields. They depend on rain, and water freely moving from one plot to another. What I'm trying to say is, he probably had to break the dam himself after making the video, so no need to worry about it's durability. But yes, there are design flaws.
Brilliant, and the amount of efficiencies you'll gain in a rebuild (once you spot them) are huge. Use the water weight more and you'll be shocked at what you'll gain.

my thoughts exactly!! like the idea, and admire its creativity.
The other systems I’ve seen like this have the impeller at the bottom of the intake. Perhaps this one isn’t as fancy.
yep, so much potential power wasted, its like 1 and half meter of height lost, just dropping from the turbines
Whenever I see this stuff I always think....How awesome it is to have your own land.

@@Tran-Chien You also, C.G.
Impressive. Try placing your turbines at a lower part of the funnels, it will harvest more power due to high kinetic energy there.
This is how I know you are in the engineering field of some sort or you just payed attention in school

So the longer the pipe, and the bigger the ratio between where the water enters/exits= more pressure/power?
@@steferos5601 faster the water is moving and the more time its had to settle so the air bubbles are somewhat gone the faster is will spin the prop,

Wouldn’t help the fact that the sides are going to erode away in a matter of weeks.

@@smelltheglove2038 I would say curved wall would give this dam authenticity. It is nice to look at. but fare from full potential.
@@smelltheglove2038 that's why he should make it not with bricks but as monolith concrete, either way filtration would ruin dam.
Definitely like the no music no commentary build. Cool to see a mini version of a dam being built.

In power station design, the high pressure end of the turbine (first stage) is smaller than the low pressure end of the turbine. These turbines increase in diameter in three steps, I think to extract as much kinetic energy from the steam as possible. However water behaves very differently to steam, being uncompressable. As laminar flow in water is our objective here, I think having a reducing taper could be a good idea 👍
@@EvilNeonETC Also, further to my last comment the amount of energy in the water is less at the top and potentially more at the bottom so tapering that is the reverse of a steam turbine makes good sense. I’m thinking that the rate of transfer of energy from water flow to turbine should be the same along its length… so yes 👍 Steam Turbine blades are also angled differently at each stage so maybe the pitch of the turbine blade should also vary along its length 🤔
Amazing,👍👍💪💪😉😉 !!!
Yes, thanks for your support ❤️❤️❤️
This dam looks really cool and took a lot of effort to build for sure. Although I am having some second thoughts on the design decisions. The wall of the dam is not built into any recess in the wall ant it is also not curved at all like all full size dam walls are. This usually helps to withstand high water pressures. Now, the video shows that the dam apparently is strong enough as is, but still - it could be much stronger. The wall is also additionally weakened by the channels alongside the channel walls that support the dam. Now, I am not an expert, but maybe this dam won't withstand the force of the river carrying high waters as is has been designed right now.
Yes .Thank you so much ❤️❤️❤️
It's also not holding back anywhere near the water pressure a full size dam is.
@@randybobandy9828 Yeah you're right, but it's also much thinner and not built out of concrete, like a full size dam would be. It is a scaled model, which is true for the amount of water it is holding back but also for the structure itself.
Bad design. Will not hold up.
I’ve got a limited amount a highly limited amount of construction experience and no I agree the wall won’t last there’s no concrete stopping erosion on the sides of those u shapes to redirect water the wall isn’t thick enough to hold that kind of weight back for a high amount of time the designs cool he just didn’t put enough meat to the damn and redirects
As you are getting better at this all (well, you were always GREAT!) you may want to start adding a voltage meter to show how much power your future damns can make.
Thank you so much 😊
Need to measure both electric current and voltage to know the power at any moment.
beautiful, wonderful... if you put the propellers in the bottom of the well, and control the flow of the vertical tube at its base, you can have much more energy.
Sangat inspiratif dan bermanfaat, salam energi listrik gratis om👍
Yes!thank you very much❤️❤️❤️
Very interesting to watch thanks CG. It just goes to show how much free power is produced from running water. Also enjoyed hearing the sounds of the speeded up footage and it's nice that the builders dog was part of the show.
Thanks for watching
Less than 5w? This was a bad design
I am almost as impressed as the dog. This guy needs to be promoted to, well, something bigger.🙂
yes thanks you very much ❤️❤️❤️❤️
This is amazing, sir. Thank you for sharing with us. You've got my attention from beginning to end. 🙌
Wow, thank you!
I really enjoy watching valuable prototypes of dams and i am learning from the professional audience with their valuable comments
Thanks for your support ❤❤❤❤❤👍
Cool project! Only one serious flaw I noticed was the lack of a curve or arch to strengthen the structure.
Yes, you are right
Super cool video. Reminds me how much we are capable of, even if there are some design flaws. I want to build something now
Yes, thank you so much 💖💖💖💖💖

Very nice bro 👍
Thanks ✌️
even the sounds of the water flowing are wounderful
Thank you very much!
@@Tran-Chien your most welcome
The spillways may be insufficient to prevent degradation of surrounding dirt wall under torrential rains. I recommend concreting the walls as well using wire mesh backing.
Yes , thank you 👍🤞😍
I was surprised this one held the weight of the water being so tall with no support on the down stream side . Which he has put more engineering into others I've watched.
But I guess he has the minimum engineering down to a science by now , knowing what will last long enough , then be easier to demolish and remove .
The engineering and investment would be out the box crazy to make it last even 1 year through the rainy season I bet. And I think all you could hope to generate electricity wise probably wouldn't even equal a small 1000 watt gas powered generator that you would get 5 years of on demand electricity out of for $2-300 dollars .
And then he probably doesn't even have the water rights to divert that much water a year ?
This was so cool! I want to make one 😄
Yes.Thank you so much ❤️❤️❤️❤️
You are an artist and a genius and you deserve all the gratitude and appreciation
Yes, thanks you very much 👍
Sin duda alguna, es un trabajo EXCEPCIONAL, mis RESPETOS 👏
Yes, thank you so much 💖💖💖💖💖
You would generate more power with bigger motors and have the turbine impeller at the bottom of the pipes. The height of the pipes will have a lot of weight and pressure of the water hitting the blades therefore able to run a much bigger motor. Water pressure is usually about 4lb per square inch and multiplies a lot more the deeper it is.👍❤️💛💚
Yes, thank you so much ❤️❤️❤️
Water pressure is ~0.5 PSI for every foot of head (depth from free surface at the top to the bottom). You have about 4 feet of head, so will have about 2 psi at the bottom and 0 psi at the top. I would also arch the dam upstream as there was no steel reinforcement to counter the bending moment on the front face of the dam, so am concerned about the dam failing at the bottom.
But since this is just a model, more about aesthetics than production, I think it looks good.
@@blacquejacqueshellaque6373 ok 👍

I think if you put the turbine generator/fins lower, it would spin faster since there would be more kinetic energy of the water falling down.
Thank you so much
Kaplan turbines work on flow. Bernoulli's principal says flow in a pipe remains constant. So that would not matter much.
Francis tubines require more pressure but much less flow. They would benefit from being placed lower in the penstock, but that is not what he built here.
Man builds dam, I watch man dam, I approve of this message.

Welcome bro
I'd like to see an update in a few months to see how well the soil walls are holding up.
Yes, thank you so much 💖💖💖💖💖
They won’t
You could see water penetrating the concrete at the top area near the turbines anyway. I'm guessing the dam didn't function for more than a day and stayed standing for less than a week. Channels like this make their project and then abandon it and go on to the next, they don't maintain any of the projects they build.
@@AbominationalFailure It's only made to film it for youtube likes for half an hour. Not at all for any kind of durability or actual use.
@@badscrew4023 that is the point I was making with my comment lol

The previous remarks do go to the betterment of the design. My experience with water at this scale points to erosion eventually destroying such beautiful work.
As a model, these designs create enormous possibilities for new projects.
Always remember that the water at the base weighs more than at the surface thus the pressure will eventually seep under the barrage's footings.
Another application might adopt a water wheel on axle to drive the turbine on a dry land position.
Regardless, we see brains at work here with different designs. Strength is the priority if the project is to survive.
A small ditch of this sort is not to be misjudged.
Yes, thank you so much 😊❤️❤️❤️❤️

Very cool, but i might recommend moving the turbines lower down for greater water pressure

What a fun project! Ofcourse your friend had to try walking accross the top of the dam! Priceless!! Thanks for sharing!
It would be so helpful if the critics could post a link to their video here to show the rest of us how they solved these mistakes on their own builds.
Thank you so much ❤️❤️❤️❤️
Awsome job

Curious to see how this project has held up, any update vids? :D
There is no structural support holding back the dam. Once the dirt gets saturated with water it will collapse.
thanks you
This seems like a village paddy field somewhere in Asia. Villagers don't have separate water supply and walls between their fields. They depend on rain, and water freely moving from one plot to another.
What I'm trying to say is, he probably had to break the dam himself after making the video, so no need to worry about it's durability. But yes, there are design flaws.
Thank you so much 😊❤️❤️❤️❤️
The crafting of the homemade screw propeller is also amazing.
Is very nice
Thanks so much 😊
Amazing!!!
Thank you so much 😊❤️❤️❤️
I think this is fantastic! I'd love to have one in my yard. Great job.
Thank you!
That's a lot of water. It's nice your dam handled this amount! Good job
Yes, thanks
Brilliant, and the amount of efficiencies you'll gain in a rebuild (once you spot them) are huge. Use the water weight more and you'll be shocked at what you'll gain.

While I appreciate the great work, should the impellers be at the bottom of the pipe to take advantage of the height?
Yes, absolutely
