HelixWind S322 Wind Turbine
This is the smaller of two vertical axis wind generators that HelixWind produces, with the larger unit selling for 70 percent more. As a vertical axis wind generator it is extremely quiet. The rotors are made of aluminum alloy and have a total dimension of four feet. It produces 2000 watts peak power, starting at 11.1 MPH. The only thing wrong with it is that it is quite expensive.
