Claim:
1. A wind turbine comprising: a. a head portion having at least two propeller blades extending radially from a hub, said at least two propeller blades having respective longitudinal axes and being mounted to said hub for rotation about said axes between a first rotational position where said propeller blades are fully engaged with incoming wind and a second rotational position where said propeller blades are minimally engaged with incoming wind, said hub being mounted for rotation on a front end of said head portion, a gear assembly mounted in said head portion between said front end and a rear end of said head portion, said gear assembly having a first shaft interconnected to said hub, and a second shaft directed vertically and downwardly, a rudder mounted on said rear end of said head portion, feathering and braking means responsive to the incoming wind, for maintaining said propeller blades in said first rotational position when the incoming winds are light and moderate, and for progressively and proportionally rotating said propeller blades into said second rotational position as the incoming winds increase from moderate to strong in strength, said feathering and braking means further applying rotational braking forces to said first shaft when the incoming winds are strong in strength; b. a tower, said tower having an upper end and a lower end, said head portion being rotationally mounted to said upper end of said tower; c. a turbine gas compressor, said compressor having a gas inlet and a gas outlet; d. a gear box located adjacent said lower end of said tower, said gear box having an input shaft and an output shaft, said output shaft being connected to said compressor, e. a main shaft, said main shaft being vertically oriented and extending from said second shaft of said gear assembly to said input shaft of said gear box; and, f. wherein said feathering and braking means includes a fin assembly on said rear end of said head portion, and in which said fin assembly has a horizontal portion with a trailing edge and an elevator pivotally attached to said trailing edge.
