Abstract: A wind rotor comprises a base, a rotor frame rotationally supported on the base for movement about a substantially vertical axis in one of a clockwise or counter clockwise direction, and a plurality of wind receiving vanes pivotally disposed on the rotor frame for movement about a substantially vertical axis in a clockwise and counter clockwise direction between a first closed position and a second open position. The movement of each vane from the first closed position to the second open position further being independent of the other vanes. A variable resistance damping mechanism assembly is disposed between each vane and the rotor frame. The variable resistance damping mechanism is configured to provide damping in both the clockwise and the counterclockwise directions, and to dampen a greater amount in one of the clockwise or counterclockwise directions than in the other.
