General windpower information

Because the ''power in the wind'' is proportional to the cube of the velocity, this means that the wind turbine on the 9 m/s site would on average be exposed to well over three-times the loads compared to the 6 m/s site. Clearly this means

Savonius wind turbine

OverviewOperationOriginPower and rotational speedUseTethered airborne Savonius turbinesGalleryExternal links

The Savonius turbine is one of the simplest turbines. Aerodynamically, it is a drag-type device, consisting of two or three scoops. Looking down on the rotor from above, a two-scoop machine might resemble the letter "S" in cross section. Because of the curvature, the scoops experience less drag when moving against the wind than when moving with the wind. The differential drag causes the Sa
