ABSTRACT:
A wind turbine is described which includes a vertical axle mounted for rotation to drive an output utilization device. Around the axle is arranged a circumferential array of wind vanes, each wind vane comprising a generally rectangular panel of flexible material supported in a frame and having a pocket opened along a vertical side which is able to flare out and catch the wind in one direction but collapse upon rotation around to the opposite direction, allowing a net output power to be generated by the wind being received in the wind vane pockets. A successive opening of the pockets insures a rapid opening action. A releasable hinging of the wind vane frame allows spilling of winds at excessive wind speeds.
