ABSTRACT:
A wind power conversion turbine motor has a body supported to rotate about a vertical axis and carrying a plurality of substantially upright vanes substantially spaced from the vertical axis and circumferentially spaced from one another so that wind thrusting propulsively against outer sides of the vanes can move across the space circumscribed by the vanes and thrust propulsively against inner sides of the vanes on leaving the space, thereby attaining dual power advantage from substantially all wind that strikes the turbine. Each of the plurality of vanes is pivotally carried on the body, with a control means to maintain a substantially constant vane angle of attack to a relative wind vector.
