An efficient, yet durable wind turbine is provided for use in windy environments even with extreme wind conditions. The turbine includes spaced apart frame members rotatably mounted upon a central axle for rotation therewith, and having a plurality of blades rotatably mounted between the frame members for rotation upon blade axles. Blade directors automatically orient the blades relative to the wind direction. The turbines are self starting, with the frame members rotating in one direction while the blades rotate in an opposite direction so as to move between perpendicular and parallel orientations relative to the wind stream. In one embodiment, the turbine can be oriented either vertically or horizontally. The central axles can be connected to an electrical generator or, if powered by an engine, can be used to provide torque or propulsion to a mechanical device.

What is claimed is: 1. A windmill, comprising: a horizontal axle; a frame mounted on the axle; first and second blades rotatably mounted on the frame on opposite sides of the axle; first and second weights connected to the first and second blades, respectively, to automatically direct the blades relative to the wind; first and second drive assemblies interconnecting the first and second weights with the first and second blades, respectively, so as to rotate the blades; and wherein the angular rotation of the blades is ½ the angular rotation of the frame. 2. The windmill of claim 1 wherein the frame rotates in a first direction and the blades rotate in an opposite direction. 3. A windmill, comprising: a horizontal axle; a frame mounted on the axle; first and second blades rotatably mounted on the frame on opposite sides of the axle; first and second weights connected to the first and second blades, respectively, to automatically direct the blades relative to the wind; first and second drive assemblies interconnecting the first and second weights with the first and second blades, respectively, so as to rotate the blades; and wherein the blades rotate 180° for each 360° rotation of the frame. 4. A windmill, comprising: a horizontal axle; a frame mounted on the axle; first and second blades rotatably mounted on the frame on opposite sides of the axle; first and second weights connected to the first and second blades, respectively, to automatically direct the blades relative to the wind; first and second drive assemblies interconnecting the first and second weights with the first and second blades, respectively, so as to rotate the blades; and wherein the blades are offset 180° relative to one another. 5. A windmill, comprising: a horizontal axle; a frame mounted on the axle; first and second blades rotatably mounted on the frame on opposite sides of the axle; first and second weights connected to the first and second blades, respectively, to automatically direct the blades relative to the wind; first and second drive assemblies interconnecting the first and second weights with the first and second blades, respectively, so as to rotate the blades; and wherein the frame includes first and second frame members between which the blades reside. 6. A wind turbine, comprising: a rotatable frame having a central pivot axis; a plurality of rotatable blades pivotally mounted to the frame radially outwardly from the central pivot axis; a plurality of blade directors, one associated with each blade to orient the blade relative to the wind; a drive assembly extending between each blade director and the associated blade; whereby wind impacting the blades rotates the frame and blades in opposite directions; and wherein the central pivot axis is horizontal and the blade directors are weights. 7. The wind turbine of claim 6 wherein each blade director is mounted on an axle and each blade is mounted on an axle, the axles being parallel and spaced apart. 8. The wind turbine of claim 6 wherein the frame and blades rotate at different speeds. 9. The wind turbine of claim 6 wherein the assembly includes four blades located 90° from one another. 10. A wind assembly, comprising: a rotatable frame axle oriented horizontally; a frame on the axle; a rotatable blade axle on the frame; a blade on the blade axle for rotation relative to the frame; a gravitational blade director connected to the blade axle to orient the blade relative to the wind due to gravity and regardless of wind direction; gears interconnecting the blade director and blade to automatically position the blade relative to the wind; and whereby the frame and blade rotate in the wind in opposite directions. 11. The windmill assembly of claim 10 further comprising a second rotatable blade axle and blade on the frame, with the blades being located on opposite sides of the frame axle and being offset 180° relative to one another. 12. A windmill, comprising: a horizontal axle; a frame mounted on the axle; first and second blades rotatably mounted on the frame on opposite sides of the axle; first and second weights connected to the first and second blades, respectively, to automatically direct the blades relative to the wind; and first and second drive trains interconnecting the first and second weights with the first and second blades, respectively, so as to rotate the blades. 13. The windmill of claim 12 wherein the drive trains each include a sprocket and chain assembly.
