Abstract
A vertical axis omni-wind turbine having a wind sail centrally mounted to a rotor, the wind sail consisting of two vanes one on each side of the rotor in generally planar arrangement. The vanes are substantially identical with each having a generally concave surface with an opposite or reverse face that is generally convex. As assembled and mounted to the rotor, one vane presents the concave face to the wind while the vane 180 degrees away presents the convex face. The concave face operates to capture the wind to force rotation of the rotor while the convex face offers minimal resistance to rotor rotation. With continued rotation the reverse, or backside, of the convex surface, which is a concave face, is then presented to the wind, thus to provide continued rotation.
