Comment Could the windbelt work as well? (Score 1) 113
I'd wondered before if something like the windbelt (http://hardware.slashdot.org/article.pl?sid=08/09/11/2257228) would work in a small stream or river. You would have the same constant flow over the belt, and I'd guess it would create the same oscillations (though probably not as much). I'm not an engineer, just curious.
