I've been installing micro hydro systems for almost 4 decades now. The amount of kinetic force that would be produced from a product like the Hydrocat would not be enough to power a generator that would produce significant power. This would be considered low head ( how many feet of drop) hydro. Low head hydro works, but the amount of money invested on a low head hydro system for the power output usually makes them not worth the investment. This company, if they still exist is providing no real data on power output based on the hydro resource that different sites would have. I would steer clear of any company that doesn't test and publish power output data, and also have a clear statement of warranty for their product.
