3d Printed Waterwheel Generator

- 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..
You are a very good engineer and you have a very good eye for detail. Very nice job
Kerbal music... absolute legend
I love it. Nice build!
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...
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.
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
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
Hi, I like this are you going to make other kits and sell them I would like to have one.
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.
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 😊
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
can you help me with the slt files its not in the actual size when i open it with cura
for low power transmission dont use gearing, use rubberband ^^ its way more efficient i think
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
Gracias por los subtítulos en español 🤗🤗
Very impressive!! Could I buy just the waterwheel part from you or do you know where I could buy one similar? Thanks!!
hello,nice job.what kind of glue you used?
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.
Thanks for sharing.
Can you please explain how you obtain 0.286 wars from kg/s and heigh in inches??
Fooool bridge rectifryeier
Could a nema 17 stepper motor be used on a gear to produce the current with a bridge rectifier ?
yes
In the words of chancellor Palpatine “unlimited power!”
Or was it infinite seizures?
can it use for overshot?
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
Nice video! What glue did you use?
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 .👌👌👌👌
собираем такие с 1977 года... все норм работает... а ты ещё не майннишь биткоин?
Wouldn't you be better of using PETG ?
What kind of software you are using for the 3D models?
That water pump looks familiar.
( ಠ ͜ʖಠ)
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
👏👏👏👍
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.. 👍
👏🏼👏🏼👏🏼 👍🏼👍🏼👍🏼
kid named 3d printer waterwheel generator:
are you from czech repablick?
no
@@HyperspacePirate ok, i thought because you have the same glue
use a pressure washer and see how much voltage you can make
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.
Thingiverse link offline!
Just checked it and it works for me. Might have been something wrong with their server when you tried
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
I don’t believe that this is real.
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
@@AngelaTheSephira no, I'm not glad, should be at least 1080p past 2012
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
