Can somebody point me to plans for a generator. |
|
I think I have the water for a water wheel. So if I can just fine a cheap or used electric generator I could mess around with making my own power. Thanks.

1. May I suggest a trip to your local "junk yard?" |
|
Generators from cars are getting harder to find, but alternators should be cheap and plentiful.
Lot easier than trying to build one from scratch.

9. Assuming 12V works for you, sure |
|
For many applications, any old alternator should be just fine.

3. Here's a different kind of water wheel that's supposed to be |

very efficient: Mini Water WheelThere are also low-head designs, like this unique and efficient whirlpool type: Zotloterer Gravitational Vortex Power PlantPost pics when you build your system :)

4. A lot will depend on your setup, really. |
|
There are commercial hydropower solutions, from small to large. Expensive. Or, if you're talking about a large, low-speed water wheel, you'll be on your own. You could adapt the alternator from a gasoline powered system. Finding one with a bad engine isn't too hard, and from there it's a matter of pulleys to get the speed you need to generate. Again, though, it all depends on how much torque your wheel can generate.
It's all been done before. Mother Earth News ran many articles on small-scale water power back in the 70s and 80s. Happily, their back issues are all on their website and you can hunt those articles down.
This kind of stuff is best suited to backwoods stuff, really. Homemade systems take a lot of fiddly maintenance and commercial setups take a very long time to get to break-even. But, for a cabin somewhere, it can be an alternative to gasoline or diesel.
All sensible systems use battery storage, unless you have a constant water flow you can tap. Even then, using battery storage and an inverter can get you more power when you need it by storing power when you don't.
Good luck. I fiddled with this stuff back in those Mother Earth News days, and had several homespun systems set up for people. Fiddly stuff, though.

5. Here's an article ..... |
|
"The heart-and-soul of this little machine is a recycled treadmill motor; the designers suggest you may be able to scrap one out of a freebie treadmill; we think you'll be likely to find a used one on a nearby Craiglist sale. In any event, the little treadmill motors put out a lot of juice for a small number of revolutions." http://www.rvtravel.com/blog/lowtech/2007/09/inexpensive-do-it-yourself-wind-turbine.html

My wife read it AFTER I took our broken treadmill to the recycle guy.I talked her into getting rid of the old treadmill. There was lots of trouble.(shivers)
I hope you understand I'm exaggerating.
