Wind and Windspinners

Contains everything you need to know about building Savonius rotor (S - Rotor) wind generator. The S-Rotor is easier to construct than a standard windmill since your generator is at the base of the tower (or the top) and is not turning around in different directions as the wind blows. This is a detailed hands-on construction manual for the complete system including the batteries, tower, control relays and the actual rotor itself.
