- In this video I build a 12" 3d printed waterwheel and use it to generate electricity from a tiny amount of water flow. The parts are all printed from PLA. It uses a 10x gear ratio to drive a rotor with 99 neodymium fridge magnets on it and generate alternating current through 33 coils. I measured the maximum power output of a the generator at about 26 mW, and the whole thing is only ~9% efficient, so there's definitely room for improvement. I think I can achieve a larger gear-up ratio without adding much friction, which could dramatically increase the power output.
The shafts / bearings are 8mm, and i used 8mm x 3mm neodymium magnets for the generator rotor. The LED sets are wired antiparallel so they illuminate on opposite phases of the generator's AC output.
Since I live in a very flat place with no natural streams nearby, I got the water flow from a tiny aquarium pump which only moves a few LPM. The wheel runs at about 35 RPM in the sink and about 20 RPM on the pump.

a ring of magnets around both outer edges of the wheel, and stationary coils on the frame, will require more magnets but removes any drag of gears, belts, chains etc!.. a great looking wheel well done..
Kerbal music... absolute legend
Hook the pump to a little solar panel and collect the water that runs out and recycle it back through the unit.
Fully functional Solar Powered Water Wheel yard unit. Very interesting.
u would need a battery to make up for the loss in energy
Just store the energy in a battery, instead of losing it in friction, resistance, and evaporation...
I love it. Nice build!
You are a very good engineer and you have a very good eye for detail. Very nice job
great build,as of lately i have been researching ways to make my own power and as of now i live right next to a brook with running water.something i would recamend is adding more cog wheels,i noticed that the light in the video was blinking and i believe that is due to the wheel not spinning fast enough.awesome work though!!
Cool build!
Maybe instead of having a separate large gear (what's the correct name for it?) would it use less material to have the gear teeth on the inside of the rim of the water wheel?
Also, for higher efficiency, try using Schottky diodes.
Also, maybe, try having coils on both sides of the magnet.
Nice! With this you could have a solar powered water pump bring water up to a large holding tank then have a water valve solenoid release the water onto the wheel where it can be stored in a lower storage tank. Be neat to see the water wheel running in cycles, especially if it was added to a diorama. Maybe have the water wheel connect to a wheel that lifts up those metal balls and have a marble machine going where the wheel powers the start of it and gravity (and maybe those accelerators) does the rest. If you made the water distilled water there would be no residue due to it being pure water when it evaporates. Just trying to toss out ideas. :)
Yep, it could be done. A water tower is a good way to store energy without batteries. The only downside is that you need a ton of space
I really like your project. They have been saying that we are in a drought... although it's raining today. I like prepping so I got a dehumidifier to make water if there is a water disruption. Also I have a desert property and the water is too deep for a water well. It takes 600w to run my dehumidifier and makes about 32 oz of water per hr. about 6 gallons a day. I plan to run it off solar panels. But I have a hill on my property and was wondering if I saved the water in a tank and then ran the water over a micro hydropower generator to a tank down the hill if it would charge a battery. I think it would be fun if you could stair step generators to make enough power to run the dehumidifier.
Hello! I’m currently building a version of this (inspired by your video). I have a question: when putting the magnets in the rotor, what orientation should their poles be? All north/south? Alternating poles? One side north one side south?
04:40 he said alternating polarity
Gracias por los subtítulos en español 🤗🤗
Fooool bridge rectifryeier
I wonder if this would work: If you want to reduce cogging but keep the cores, you could make the number of coils one fewer than the number of magnets, so that the torque would cancel out. I guess then you might have to do something fancy electrically.
Wow, that's a very nice build😄 Will we see a wind powered version of this in the future?
Yes. I live a few minutes away from the Atlantic ocean which always has a really strong wind, so I'm planning to build a portable wind turbine for the beach
@@HyperspacePirate we'll be glad to see that😄 how about having two rotors and one stator in between? You know, having magnets from both ends , although you might have to slightly alter the stator placement... Just suggesting😅
@@CuriousChan I was thinking more along the lines of a single rotor and stators on both sides. In the future, I think I'll switch to a radial arrangement, though, because the axial loading has caused some problems bending materials etc
Excellent
Te falta mucho por aprender , #1 usar súper capacitores , #2 diodos, para que la corriente no vire , #3 una bomba de agua , y así usar la misma agua que cae , #4 un inversor de corriente , #5 amplificar la corriente que sale del rectificador , y #6 las bobinas y los imanes están mal colocadas , y en una cantidad , inusual .👌👌👌👌
hello,nice job.what kind of glue you used?
Thanks for sharing.
Can you please explain how you obtain 0.286 wars from kg/s and heigh in inches??
Bonjour je suis sur que tu à asser de couple avec ta roue pour faire du courant et alimenté ta pompe en circuit fermé er elle tournera toute seule sans etre brancher sur le réseau électrique ! Bonne continuation
You had 33 sets of magnets and 33 coils in the first iteration, correct? You removed the fero cores and reduced the cogging, could you not have changed up the number of either coils, or magnets such that you didn't have a single "cog" effect?
i.e., 33 magnets and 29 coils? (Or some other set of numbers that created both and "in-phase" and "out of phase" arrangement between the coils and magnets?)
Nice build
Where about in FL are you at? I live in FL and would love to find a buddy that is interested in making projects like this 😊
Very impressive!! Could I buy just the waterwheel part from you or do you know where I could buy one similar? Thanks!!
собираем такие с 1977 года... все норм работает... а ты ещё не майннишь биткоин?
In the words of chancellor Palpatine “unlimited power!”
Or was it infinite seizures?
Nice video! What glue did you use?
What kind of software you are using for the 3D models?
I have a theory that I would like to see tested. Take a water wheel, then multiply it by a number. Let's say 10. You make a 10' tall tower and install those 10 water wheels vertically in the tower, one directly above another. You have a water pump, like your aquarium pump, pumping water to the top of the tower,. Then that water, pumped once, spins all 10 wheels. Pump once; use the water ten times. Will it use more power to pump that water up 10' than 10 of those water wheels can produce?
A quick way to answer these kind of questions is “will this give me perpetual motion?”.
If it takes less than 10 water wheels to produce enough power to pump your water up into these 10 water wheels, you can generate more power than you input in the system. You get perpetual motion. Which is, according to the known laws of physics, impossible. So, no, you would not get back more energy than you put in.
In this case specifically, the energy you get from the water wheels is provided by gravity. The energy you put into the pumps is used to fight gravity. And most of this energy you put in is lost to inefficiencies in the system (friction and other things). What you get back would be at most what you put in (in a perfect system impossible to achieve in the real world).
Here, he mentions at 6:16 an efficiency of 9%. Let’s round to 10% to make it easy. You would need 10 water wheels worth of power to pump your water the height of one water wheel only (even more than that in reality since 9% is “best efficiency”).
The “perpetual motion test” is a good tool to understand these ideas. If you theorize perpetual motion, you’re wrong somewhere, and if you observe perpetual motion, you have an energy input that you are not aware of. The rest of the work is to find “what did I miss to end up with perpetual motion?” (which is not always obvious).
@@daeldir - I'm so tired of being told that perpetual motion is impossible. I believe very strongly that it's possible, but that the big money in the oil industry won't allow it to get a foot hold.
@@need100k I didn’t say it was absolutely impossible. I said it was “according to the known laws of physics”, impossible. At this point the oil industry is not the limiting factor, the laws of thermodynamics are. We could be wrong. The laws of thermodynamics as we stated them could be invalid. Some hidden nugget, generations of physicists failed to detect, could be uncovered. We can dream. But the laws of thermodynamics have stood the test of time, we failed to disprove them a lot, as is required to have a good scientific theory. We are coming back to this idea of efficiency. For your idea to work, the water wheel would have to be _strictly more_ than 100% efficient. We don’t know how to do that, and a water wheel capable of transforming 9% of the energy provided to it into electricity is definitely not the way to go.
Here is some hope for you, whichever you would dare to cling to:
- We are still missing a grand theory unifying general relativity and quantum theory. We can imagine a world in which, once we found a way to unify the two theories, one of the resulting law enables us to go past the limitations our current understanding of physics subjects us to.
- We could be living in a simulation, and an imperfect one as that, and while the laws of thermodynamics are supposed to hold true in theory, in practice, we could find a bug to exploit for infinite power. As we do regularly in video games. If we live in a simulation.
- An angel could descend from the sky and show how mistaken we are in our epistemological conceptions. As a gift for his visit, he could grant us a wish to have a perpetual machine to study. Free miracle, limited edition, barely used.
The Wikipedia article on perpetual motion is a very good read to understand the lack of belief in perpetual motion of many scientists. As things stand, the big money in the oil industry already had a firm grip on the speech of Leonardo da Vinci, who was also accepting money from big pharma, hence his likening the quest for perpetual motion to alchemy, discrediting two perfectly fine disciplines in one sentence (once we have broken the laws of thermodynamics, time travel is definitely on the table, but we are doomed since the oil industry seems to have access to it “already”).
@Just Me if it was possible, why hasn't anybody come out with it? Especially if it was as simple as stacking waterwheels. And there are much richer corporations than oil corps, that would love to pay less for electricity. so why wouldn't those figure it out?
@daeldir
I live the explanation followed by the snark
Could a nema 17 stepper motor be used on a gear to produce the current with a bridge rectifier ?
yes
That water pump looks familiar.
( ಠ ͜ʖಠ)
Wouldn't you be better of using PETG ?
Looks like it ran itself
In the videos it's being run by a pump to provide the falling water for the sake of demonstration because I don't live in an area with a natural source of fast-flowing streams. It's definitely not a free energy thing
Have you heard of the N machine that will run itself
can it use for overshot?
👏🏼👏🏼👏🏼 👍🏼👍🏼👍🏼
👏👏👏👍
output of 26 miliwatt? ha lol a small 1cc hog air engine produce triple of that in electricity with a peak of 150 mw mechanical XD but its less energy efficie at 8ml alchool 45 min its aproximatly a 80 watt thermal used for 75mw electric

@@HyperspacePirate ok, i thought because you have the same glue
Nice build
Can you share the 3D files
I updated the description with a link to the STL files. Might take a moment for them to appear because I just uploaded them
@@HyperspacePirate Thanks
Great.. 👍
This channel should be called tech in 720p 😂 dude it's not 2010
And this was uploaded in 2022. Be glad it's even 720p

Just checked it and it works for me. Might have been something wrong with their server when you tried
I should have studied in school.
Hi there real nice build I would like to ask if you could print me a set and sell it to me if you might what would the cost please reply back on this thank you.
hmmm at :51, Too much lip, on the buckets.! at 1:12, it's always good to not have a clue.! Too many buckets. and, at 2:42, THINGS GO SIDEWAYS.!!!!!! at 3:23, that is NOT the Radius where the magnets (and coils) should be.!!!!!! a NORMAL, efficient generating coil is made with 14awg wire, NOT thirty gauge.!!!!!!! at 3:39, lmfao totally screwed up.! at 5:34, the giant copper sewing machine that ate milwaukie. at 5:49, cap in the output circuit is a CHEAT.!!!!!!! at 6:07, BEFORE losses.! at 613, resister values.???? at 6:56, water should enter the buckets at about One-o'clock. Not 2:30. the 'wheel SHOULD turn Slowly enough, that a bucket can Partially Fill up.!!!!! at 7:53, gear teeth are STROBING like crazy.! googletranslate
ok
