Build Your Own Hydro Electric Generator

A thought occurred to me the other day about all the data we know about building your own wind turbine. Why not employ the same principles used to build a wind turbine, to build a hydro-electric generator. However this is not for everyone. One requirement that you must have is access to a flowing aqua source, rather it would be a steady flowing creek or a creek you could easily divert. More information: window tint.
