Has anyone tried this. The property that I am looking at has a spring fed stream, that I thought about building a little dam on to fill a stocked pond. Then I got to thinking about maybe adding a little generator to the dam, doesn't have to generate a butt load, just a steady current to charge the batteries. Sounds like a good plan to me, what are your thoughts? I am thinking of the dam to fill up the pond, then an over flow area that would turn the generators. Basically putting a huge U in the flow of the stream that will eventually go over a small waterfall turning a generator.
