Abstract:
1. A vertical axis wind turbine for storing energy, said wind turbine comprising: (a) a turbine rotor with a support platform, a rotatable vertical shaft extending from said platform, at least one bearing for said vertical shaft, and at least three rotor vanes disposed for rotation about the vertical shaft, each rotor vane having four solid sides, a front side and a rear side disposed in radial vertical planes, the front side being substantially open faced and the rear side having a rectangular opening surrounded by a support rim that connects to the rear of the four solid sides, said opening covered by a plurality of flaps joined to the rotor vane with a plurality of hinges, each of said flaps being capable of: moving about a horizontal axis of rotation with a directional passage of wind through the rotor vane; and preventing air from flowing through the rotor vane when forced against the support rim on the rear of the four solid sides; and (b) means for attaching each rotor vane to said vertical shaft so that the front side of each vane lies in the same rotational direction around said vertical shaft.
