POWER GENERATION APPARATUS
First Claim
1. Power generation apparatus comprising a rotor rotatably mounted to a support, a plurality of vanes extending radially out from the rotor and positioned to be engaged by a moving fluid stream, each vane including a wing-shaped main blade having opposite surfaces, a leading edge and a trailing edge, a co-extensive conditioner blade having opposite surfaces, a leading edge and a trailing edge and being spaced parallel to the main blade so as to define therebetween a slot having an entrance and an exit, and a lift varying device bordering the slot in each vane to vary the lift produced by that vane inversely to the speed of the moving fluid stream.

Abstract
A power generation apparatus comprises a rotor rotatably mounted to a support and a plurality of vanes extending radially out from the rotor and positioned to be engaged by a moving fluid stream. Each vane includes a wing-shaped main blade having leading and trailing edges, and a co-extensive conditioner blade having leading and trailing edges. The conditioner blade is spaced parallel to the main blade so as to define therebetween a slot having an entrance and an exit. A lift-varying device boarders the slot to vary the lift produced by that vane inversely to the speed of the moving fluid stream so that the rotor turns at a relatively constant rate. The rotor, driven by wind or water, may be coupled to the armature of an induction motor/generator to produce electric power.
