<p>A vertical axis omni-wind turbine having a wind sail centrally mounted to a turbine drive shaft, the wind sail consisting of three generally identical vanes, or blades, separated 120 degrees apart. The blades each have a generally concave surface with an opposite or reverse surface that is generally convex. As designed and mounted to the turbine drive shaft, the wind sail provides a self starting air foil in that each blade includes one side having a generally concave configuration to capture impinging wind thrust with the other side having a generally convex configuration to provide minimal wind resistance. The resulting disparate wind resistance causes a stronger reaction on the concave side of a vane which in turn provides rotation about the vertical oriented drive shaft. The turbine has omni-wind characteristics in that regardless of the wind direction an adequate portion of the concave surface of a rotor blade will always be exposed to impinging wind. The subsequent drive shaft rotation is transmitted to an electrical turbine.</p> |
