Other than heat and artificial light, I think most of these Aquaponic systems use very little power. A small pond pump can water an entire garden if you use the river bed continuous flow system or a combination thereof.Originally Posted by muzzelloader
I'm sure a small wind mill, a decent solar panel, and a battery or two would certainly be able to power your pump. One could also invest some time (or money if you prefer to buy one) in a passive solar heater. They are amazing devices. I plan to use one to heat my home this year. Here is an example of one http://www.youtube.com/watch?v=Jzxw1j-dzY4.
