Abstract
An impeller having an axle with radial vanes is mounted within a housing. The housing includes a funnel to direct a large amount of wind into the impeller. Air fins on top of the housing maintain the funnel pointed into the wind. A flap upon the top of the housing will fold downward as the wind increases and this will raise a throttle valve at the throat of the funnel. In addition, the flap will close exhaust openings from the housing, also reducing the wind on the vanes. Two additional flaps act as pressure relief valves in the funnel which open to dump wind at excessive velocity. Furthermore, a leeward flap on the side of the funnel is blown out to an extended position at high winds which causes the housing to rotate upon its circular tracks to bring the funnel opening away from the wind. The air fins on top of the housing are blown down from the vertical position as the wind strikes the housing sideways. The housing is mounted upon a frame which extends horizontally outward from the housing. The frame is mounted by wheels upon concentric rails. Therefore, the housing can be maintained directly into moderate winds by rotating around upon the rails or high winds will cause the housing to rotate away from the wind. The large frame prevents the unit from blowing over.
