ABSTRACT:
A wheel-type of moving water energy conversion device consists of a limited number of paddles or blades attached to struts, which are secured to a central axis or geared drive shaft. The paddles or blades are hinged to the struts in a unique underneath forward position, allowing the paddle or blade to enter water in an energy conversion, flat plane and exit from water in vertical non-water lifting position. The utilization of extension arms securing paddles, the limitation of engineered positioning of paddles and the design of free paddle exit from water, provide a uniquely efficient energy conversion device for use in moving waters, such as rivers, streams, tidal flows or lake and ocean waves and currents. The device may be engineered as a low profile, rotary barrage type, with paddles or blades positioned on struts with or without telescopic arms.
