Patent ID: 8282339

Claim:
A segment for a fluid driven turbine, comprising: a first wall to be coupled to a shaft; a second wall asymmetric to the first wall and the shaft, having a first portion that creates a drag force when fluid moves along the first portion of the second wall, and a second portion flattened toward the first wall that creates a lift force when fluid moves along the second portion of the second wall; a third wall joined to the first and second walls; and a fourth wall joined to the first and second walls opposite the third wall; the first, second, third and fourth walls forming an inlet at a first end of the segment; and the first, second, third and fourth walls having an outlet opening formed therein at a second end of the segment where fluid moving through the segment exits the segment and at which a jet force is created as the fluid exits the segment, the segment having its smallest cross-sectional area at the outlet opening.
