I have been thinking about setting up something outdoor this summer, so I started looking into solar power. I started thinking basically all of your power usage is moving water. If had enough places where your water is falling with a water wheel set up to catch you could get a lot of your power back. You may even be able to catch the force of your bubbles from your air stone raising.

I don't know much about solar power, or hydro. Has anyone here gone down this road before? Any insight or experiences would be very helpful to me.
