Patent ID: 8534057

Claim:
An apparatus for generating electricity from a flowing stream of water, comprising: a rigid frame; a first pair of wheels rotationally fixed with the frame, coaxially aligned and rotationally mutually coupled; a plurality of blades rotationally fixed proximate top edges thereof between each pair of wheels proximate peripheral edges thereof, the top edges of the blades being substantially parallel to a common axis of the first pair of wheels; a means for maintaining orientation of each blade, such that one rotation of the first wheels results in one revolution of the top edge of the blade about the common axis while maintaining the orientation of the blade; whereby the frame may be above the stream of water such that the flow of the stream of water causes each blade to rotate into and out of the stream of water, each blade entering and leaving the stream of water oriented generally orthogonally to the flow of the water, thereby rotating the first pair of wheels which, being mechanically coupled with a generator, produces electricity.
