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
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.
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 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 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
I pride myself on being mechanically and technically competent in a range of fields, I could wire up the electrical side of this project with no problems. But here I learn that it's also very handy to have the skills to build the kind of structures which allow you to put those mechanical/technical systems to good use. Now I want to learn how to lay brick and cement render like this guy! Cool project!
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.
What an excellent craftsman this guy is ! It would be very easy to increase the power output just by mounting the impellers on a longer shaft (with additional bearing to keep it central) so they are at the bottom of the overflow pipes , but that and the comments about the longevity of the design aside, it really is excellent craftsmanship !!
You know this was never intended to make power right? It’s purely to get views. They would have walked away from it the next day and never even cleaned up the mess. I can’t imagine that flooding the area behind the dam by 5 feet would do much good to the area too.
@@garrysekelli6776 none because this design doesn't produce any usable energy, turbines need to at the lowest point of the dam to use the potential energy of the height delta
Congratulations to this guy. Having managed construction of a small micro-hydro electrical project (14-17 kva) with 2 separate locations and 1 mile of pipe between them. Access was difficult at my site and time consuming and involved 9 miles of barge/lake travel. Without knowing this man’s surrounding terrain I would find it difficult to be critical. Yes the turbine should be low, the dam should have wings and so on. Or you could lay a pipe siphon with valves across the top of the earth to his small generator. You already have the existing dam.
Молодец! Просто и красиво! Турбинки нужно опустить ниже (там давление выше) В конце окончательно понял для кого был сделан мост. Самая любознательная собака! Все посмотрел, все понял и наверное надо надо собаке поступать в гидротехнический институт.
The real accomplishment here is 8M views. The design was perfect for that. I’m sure he could have built a dam that generated way more power. I’m also sure that that wasn’t his goal at all. Perfect design for the goal intended.
I am amazed how he constructed a dam with a brick wall…. Even a small tank requires retaining walls 😅… even though there are lots of other engineering problems I like your craftsmanship 🥳🥳
Да вся конструкция простоит максимум два дня, пока грунт стенки канала не промокнет, вообще не понимаю, как кирпичная стена держит давление в тонну, если её с ноги можно поломать?
Well... it does look like it was maybe in China so..,..yea.. I mean, the Yangtze still floods and high rise building just randomly fall over there so... engineering isn't really their strength. Stealing others people's and countries designs and artistic property....now they are damn good at that! They excel in that realm!!!! Damn,... hope I TH-cam and Biden don't take what I said the wrong way. I don't wanna get banned from TH-cam and...wait..is that a black helicopter heading this way. Holy Crap! LeBron James is in the gunner position. Damn.... I've gone to far this time!
Dude, I'm amazed at how much " "basic" " eduction, common sense and experience was put in this video. The part when he uses a large pipe to bend the blades of the turbine so they have a more or less weldable curve blew up my mind. As you say there are a lot things that are wrong but I think this video is not just good because his craftmanship... If it serves to spark somthing in the mind of a kid or a teenager, if it serves to push them even if just a little to experiment and learn... I think that make this content also valuable. 😉
That is very cool man! Some people would probably pay to have a small electric generator like this installed if you can make it a reliable 48v/24v/12v generator with enough amps.
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.
I bet seeing all these dams at night with the lights in full shine is very fulfilling for you. It like a long day doing yard and just being able to enjoy it at the end. peace and quiet. Nothing beats nature
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 🤔
I’m curious, do you build all these mini-dams in the same district or many places around Vietnam? Where’s your district? Now Vietnam has opened up to tourists, I would like to see your mini-dams in person. Any recommendations? Thanks 🙏🏼 🇻🇳 ❤️
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.
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
Great idea in general. Obviously there could be improvements to efficiency and durability but the video did a great job of just showing what is possible. Thank you for sharing and putting so much work into the project.
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.
"Fun, small scale model of hydroelectric dam" is the correct description. I was looking for a serious power generation example that would hold up for more than a few weeks. Fun art project, if you've got the location and nothing better tot do I suppose.
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.
Post the real time version of this as well as this accelerated one. I, for one, could watch that as long as it takes start to finish. Fascinating, educational AND entertaining.
This was so cool. And something DIY that anyone could do who lives in area where power is unavailable or to expensive. Anything is possible. Again this was awesome 👍👍👍
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.
I could be wrong but this seemed more like an art project/labor of love. The suggestions in the comments are fantastic, but if it wasnt needed for actual power generation then it already came out really cool
Friend, what is this part that you connect each engine to? In the video, at minute 11:06 you connect the wires coming out of the motor to this piece. What is this piece? You turn the motor and the little red lights are lit. What is this little box? Another question, what are these motors? A hug from Brazil...
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.
Awesome craftsmanship. I think that if you are really interested in extracting as much power as possible out of your system, then replacing the both electricity generators with an 'overshoot water wheel' will get you the most energy with easiest effort. The water wheel would receive water from the over flow at the top. As mentioned in other posts, your current design is good for a stream with fast flowing water. A water wheel will get you ten times more power than your current design. Putting the existing turbines as low as possible in the pipe will get more electricity, but not that much. Building a water wheel is a big job, but will yield much more power.
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.
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.
what am I doing? I need to print my resume and get ready for a job interview tomorrow. Awesome vid dude, bought to watch more. You're doing everything I wanted to do as a kid

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

Impressive. Try placing your turbines at a lower part of the funnels, it will harvest more power due to high kinetic energy there.

So the longer the pipe, and the bigger the ratio between where the water enters/exits= more pressure/power?

It would be very easy to increase the power output just by mounting the impellers on a longer shaft (with additional bearing to keep it central) so they are at the bottom of the overflow pipes , but that and the comments about the longevity of the design aside, it really is excellent craftsmanship !!
Yes, thank you so much 💖💖💖💖💖
Also, having multiple turbines on one tube would help, at least, last time I've seen something similar, it had multiple in one...
You know this was never intended to make power right? It’s purely to get views. They would have walked away from it the next day and never even cleaned up the mess.
I can’t imagine that flooding the area behind the dam by 5 feet would do much good to the area too.
@@Mi-ck it doesn’t really matter - it is just a nice demonstration of craftsmanship and nice to see something positive
@@adamrawicz-szczerbo8948 it's not positive though, that's the entire point
As always; amazing work. I wonder how many hydropower plants has this guy built? His whole neighborhood should have one in every corner by now.
Thank you so much 😊
How many kilowatt hours Total this one guy has produced. Probably more than the Hoover dam.
he even though about animals friendly passage!
@@garrysekelli6776 none because this design doesn't produce any usable energy, turbines need to at the lowest point of the dam to use the potential energy of the height delta

Congratulations to this guy. Having managed construction of a small micro-hydro electrical project (14-17 kva) with 2 separate locations and 1 mile of pipe between them. Access was difficult at my site and time consuming and involved 9 miles of barge/lake travel. Without knowing this man’s surrounding terrain I would find it difficult to be critical. Yes the turbine should be low, the dam should have wings and so on. Or you could lay a pipe siphon with valves across the top of the earth to his small generator. You already have the existing dam.
Yes!Thank you very much!
Looks nice but it's not making 14K lol maybe just enough to power the lights
Молодец!
Просто и красиво!
Турбинки нужно опустить ниже (там давление выше)
В конце окончательно понял для кого был сделан мост.
Самая любознательная собака!
Все посмотрел, все понял и наверное надо надо собаке поступать в гидротехнический институт.
Yes, thank you so much 💖💖💖💖💖
Тоже не понял этого. Зачем строить высокую плотину, если турбина чуть опущена?
The real accomplishment here is 8M views. The design was perfect for that. I’m sure he could have built a dam that generated way more power. I’m also sure that that wasn’t his goal at all. Perfect design for the goal intended.
Thank you 😊
Can someone please buy this guy a pair of shoes?
Why you can't
Cement!
I am amazed how he constructed a dam with a brick wall…. Even a small tank requires retaining walls 😅… even though there are lots of other engineering problems I like your craftsmanship 🥳🥳
Да вся конструкция простоит максимум два дня, пока грунт стенки канала не промокнет, вообще не понимаю, как кирпичная стена держит давление в тонну, если её с ноги можно поломать?
Well... it does look like it was maybe in China so..,..yea.. I mean, the Yangtze still floods and high rise building just randomly fall over there so... engineering isn't really their strength. Stealing others people's and countries designs and artistic property....now they are damn good at that! They excel in that realm!!!!
Damn,... hope I TH-cam and Biden don't take what I said the wrong way. I don't wanna get banned from TH-cam and...wait..is that a black helicopter heading this way.
Holy Crap! LeBron James is in the gunner position. Damn.... I've gone to far this time!
Dude, I'm amazed at how much " "basic" " eduction, common sense and experience was put in this video. The part when he uses a large pipe to bend the blades of the turbine so they have a more or less weldable curve blew up my mind. As you say there are a lot things that are wrong but I think this video is not just good because his craftmanship... If it serves to spark somthing in the mind of a kid or a teenager, if it serves to push them even if just a little to experiment and learn... I think that make this content also valuable. 😉
@@Marotonella You should watch some Pakistanis on YT working on vehicles. As a mechanic by trade they use primitive methods that always blow my mind.

Helloo
Nahh, this is the manifestation of a proper work / fun balance.
That is very cool man! Some people would probably pay to have a small electric generator like this installed if you can make it a reliable 48v/24v/12v generator with enough amps.

24V
I can't say I've ever been so bored I built a hydro-electric dam.
Very cool.
Yes.Thank you so much ❤️❤️❤️❤️
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.
Better than I could do. That is some satisfying work you're doing while I watch you do it in this video. Great job
Yes, thanks you very much 👍
Круто, золотые руки и здравый ум!

Cool project! Only one serious flaw I noticed was the lack of a curve or arch to strengthen the structure.
Yes, you are right
What a masterpiece and a beautiful build too. Thanks for posting this as well. Have a nice day.

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

People like this man are the reason I had a great childhood😌
Thank you very much❤️❤️
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. 🙏🙏🙏
thank you so much 💖💖💖💖💖
@@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 🤔

Where’s your district? Now Vietnam has opened up to tourists, I would like to see your mini-dams in person. Any recommendations? Thanks 🙏🏼 🇻🇳 ❤️
lol for sure he gonna tell you where he lives. you basically asked him to dox himself
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 😊❤️❤️❤️❤️
Have you ever tried to see how much power they can put out? I'm curious what kind of things you could power/charge with one of these.

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 😊❤️❤️❤️❤️

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.
Awesome craftsmanship. I think that if you are really interested in extracting as much power as possible out of your system, then replacing the both electricity generators with an 'overshoot water wheel' will get you the most energy with easiest effort. The water wheel would receive water from the over flow at the top.
As mentioned in other posts, your current design is good for a stream with fast flowing water. A water wheel will get you ten times more power than your current design.
Putting the existing turbines as low as possible in the pipe will get more electricity, but not that much. Building a water wheel is a big job, but will yield much more power.
thanks you 👍👍👍💖💖
This is really impressive. Thank you for filming this!
Yes, thank you so much ❤️❤️❤️
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.

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.
