This vertical axis wind turbine (VAWT) uses five 3” PVC pipes cut in half for blades rotating on three kids bicycle wheels to spin an Ametek 38 volt motor or a wind blue alternator. The whole thing spins in a frame that is a 12 feet high and 2 foot square box that is able to sit on his deck. In total it cost him about $125 plus time, a bit more if you use the wind blue alternator.
