Small Wind Turbine

Everybody wants to have a cleaner Earth, but few of them take any actions. One of those people is Doug Selsam, who designed high-power wind turbines that can generate enough energy to power a home. The wind turbines measure about 14-18 inches in diameter and they can generate an impressive amount of 200 watts for a 20 mph wind, but the wind turbines could do better if the winds are stronger.
