A wind driven electric generator apparatus includes a pair of wind-driven, counter-rotating propeller units placed back to back with each other. A first power transmission system is connected to the pair of counter-rotating propeller units for converting wind energy into mechanical energy. A second power transmission system is connected to the first power transmission system. A generator is connected to the second power transmission system for converting mechanical energy into electrical energy. Propeller unit orientation means are supported by a first transmission housing for orienting the pair of counter-rotating propeller units with respect to wind that is sensed. Self-adjusting propeller blade angle adjustment means are supported by the pair of counter-rotating propeller units for adjusting propeller blade angles in response to wind that is sensed.

What is claimed as being new and desired to be protected by LETTERS PATENT of the United States is as follows: 1. An electric generator adapted to be connected to a power transmission system, comprising: a generator housing, an armature assembly support structure housed within said generator housing, a rotation/counter-rotation drive assembly supported by said armature assembly support structure and adapted to be coupled to said power transmission system, a rotatable interior armature assembly connected to said rotation/counter-rotation drive assembly and supported by said armature assembly support structure, a counter-rotatable armature assembly spaced apart from and surrounding a portion of said rotatable interior armature assembly, wherein said counter-rotatable armature assembly is supported by said armature assembly support structure and is connected to said rotation/counter-rotation drive assembly, and wherein said rotation/counter-rotation drive assembly includes: a generator drive shaft adapted to be connected to said power transmission system, wherein said generator drive shaft is connected to said rotatable interior armature assembly for driving said rotatable interior armature assembly in a first rotational direction, a generator sun gear connected to said generator drive shaft, a plurality of generator planetary gears connected to said generator sun gear, a generator ring gear encircling and connected with said generator planetary gears, wherein said generator ring gear is in contact with a front wall of said counter-rotatable armature assembly for driving said counter-rotatable armature assembly in a second rotational direction which is counter-rotational to said first rotational direction. 2. The apparatus of claim 1 wherein: said counter-rotatable armature assembly includes a counter armature rear wall and a counter armature front wall, said rotatable interior armature assembly includes a interior armature front wall and a interior armature rear wall. 3. The apparatus of claim 2 wherein said counter armature front wall includes a drive-shaft-to-front-wall roller bearing. 4. The apparatus of claim 1 wherein said interior armature front wall and said interior armature rear wall include coolant flow-through channels. 5. The apparatus of claim 1, further including: a rotatable armature-to-armature bearing assembly connected between said rotatable interior armature assembly and said counter-rotatable armature assembly. 6. The apparatus of claim 5 wherein said rotatable armature-to-armature bearing assembly includes: a plurality of rollers supported by said counter armature rear wall, and a roller-reception flange supported by said interior armature rear wall, wherein said roller-reception flange receives said rollers, thereby permitting said counter-rotatable armature assembly and said rotatable interior armature assembly to rotate in opposite directions from each other. 7. The apparatus of claim 1, further including: a fluid coolant system supported by said generator housing or said armature assembly support structure for cooling said counter-rotatable armature assembly and said rotatable interior armature assembly. 8. The apparatus of claim 7 wherein said fluid coolant system includes coolant spray nozzles supported by said generator housing or said armature assembly support structure. 9. The apparatus of claim 7 wherein said fluid coolant system includes a radiator for cooling the coolant. 10. The apparatus of claim 1 wherein said rotatable interior armature assembly includes: a pole and coil array which is surrounded by said counter-rotatable armature assembly, an interior armature front wall and an interior armature rear wall which support said pole and coil array, and an inner tubular axle supported by said interior armature front wall, wherein said inner tubular axle includes wire-reception channels for receiving wires from said pole and coil array, wherein said wires, are connected to rotating electrical contacts connected to said inner tubular axle. 11. The apparatus of claim 10 wherein said counter-rotatable armature assembly includes: a peripheral counter-rotatable armature assembly portion which jackets the outside of said pole and coil array, and a center counter-rotatable armature assembly portion which extends into an interior portion of said pole and coil array. 12. The apparatus of claim 11 wherein said peripheral counter-rotatable armature assembly portion includes: a counter armature front wall, a counter armature rear wall, a plurality of peripheral outer shell segments sandwiched between said counter armature front wall and said counter armature rear wall, a plurality of outer-shell-to-outer-shell magnets interconnected between adjacent peripheral outer shell segments, a plurality of peripheral inner shell segments adjacent to said peripheral outer shell segments, a plurality of inner-shell-to-inner-shell magnets interconnected between adjacent peripheral inner shell segments, and a plurality of outer-shell-to-inner-shell magnets interconnected between adjacent peripheral outer shell segments and peripheral inner shell segments. 13. The apparatus of claim 11 wherein said center counter-rotatable armature assembly portion includes: a plurality of center individual magnets, a plurality of center magnet interconnector members connected between said center individual magnets, a plurality of shell-to-shell magnets, and a plurality of center assembly shell segments connected to said shell-to-shell magnets and a portion of said center individual magnets, wherein said center individual magnets are arrayed in a plurality of positive-pole-to-negative-pole arrangements, and wherein said center assembly shell segments are arrayed in a positive-pole-to-negative-pole arrangement around said array of said center individual magnets. 14. The apparatus of claim 10 wherein said pole and coil array includes a plurality of pole and coil units. 15. The apparatus of claim 14 wherein said pole and coil units are arrayed as opposing pairs of pole and coil units. 16. The apparatus of claim 10 wherein each pole and coil unit includes: a top pole portion, a wire-reception post extending downward from said top pole portion, a bottom pole portion connected to said wire-reception post, and a quantity of wire coiled around said wire-reception post to form a wire coil mounted on said wire-reception post. 17. The apparatus of claim 16 wherein a continuous quantity of wire extends from each wire coil in each pole and coil unit through said inner tubular axle to rotating electrical contacts connected to said inner tubular axle. 18. The apparatus of claim 16 wherein said wire-reception post and said wire coil are substantially coextensive with said top pole portion and said bottom pole portion so that said wire coil is substantially coextensive with magnetic flux generated by said inner core magnet array. 19.
