Just to add to this interesting discussion, 746watts equals 1 Horse power. So lets say 20 amps x 14.2v = 284 Watts double it for losses. 568 Watts. Now 568/746 = 0.76 Hp. A lot less than has been suggested and still free power.

I'm a bit confused about the comparison in losses between the PSA and a wind generator. Water is far denser than air. The prop becomes a speed brake of sort. I'm not a physicist but I'd wager that amp for amp the performance loss with a wind generator is negligible compared to a PSA.
