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 ...

Freen introduces the Freen-20 turbine-an innovative, efficient small wind turbine with a seven-week payback, making wind <a ta ...

There are two basic types of wind turbines: horizontal-axis and vertical-axis. Horizontal-axis wind turbines (HAWT) have a two or three blade rotor that rotates about a horizontal axis. The rotor is ...

The industrial three-blade wind turbines are more efficient than these vertical-axis turbines as only one side of the turbine faces the wind. Secondly, they cannot capture the stiff coastal wind like ...
