Here is an idea I am working on. Trying to build a magnetic motor that will hook up to the water wheel, turbine, what ever I find that works better. Been tinkering with this for a few months. Maybe one of these days this winter I will get it working.
I'm thinking of charging a few batteries from this system. Just to create it's own power, not running my house or anything from it. Just an air pump, and maybe a water pump. I made a mini hydro electric generator from some crap parts laying around to test the idea. I can get 40 VAC from the tiny model. I think that motor may have been from a dishwasher or something like that. The motor I'm building now is 4 phase, 400 volts. It will be a monster, hopefully will do the job and more.
