Thank you for your response to: Hydroelectric converter. It is not a dam. The unit is placed in a free flowing river and does not impede the flow. It doesn't have blades, either. It consists of cylinders that operate on a princple of fluid motion and doesn't impede or harm fish. A local underwater photographer set up live river cams and verified that the fish had little to no response to the apparatus. More info can be found @http://www.vortexhydroenergy.com/
