1. 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; anda 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; andthe 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. 2. The segment of claim 1, wherein the first wall is separated from the second wall by the outlet opening. 3. The segment of claim 1, wherein a distance between the first wall and the second wall is continuously reduced from the inlet to the outlet opening. 4. The segment of claim 1, wherein a distance between the first wall and the second wall is less at the outlet opening than at the inlet. 5. The segment of claim 1, wherein at least a portion of the second wall is formed in the shape of a logarithmic spiral. 6. The segment turbine of claim 5, wherein the portion of the second wall formed in the shape of a logarithmic spiral is the portion of the second wall that extends from the inlet. 7. A turbine comprising: a shaft;a segment attached to the shaft and including: a first wall coupled to the 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; anda fourth wall joined to the first and second walls opposite the third wall;the first wall, the second wall, the third wall, and the fourth wall forming an inlet at a first end of the segment and having an outlet opening formed in the first wall, the second wall, the third wall, and the fourth wall 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; anda generator coupled to the shaft. 8. The turbine of claim 7, further comprising a base supporting the shaft and the generator. 9. The turbine of claim 7, wherein the shaft is coupled to the generator through a hub coupled to the shaft and the generator. 10. The turbine of claim 9, further comprising a plurality of generators, wherein at least one of the generators is disengagable from the hub. 11. The turbine of claim 10, wherein the at least one disengageable generator is disengaged from the hub when the speed of the turbine decreases below a predetermined speed. 12. The turbine of claim 10, wherein the at least one disengageable generator is engaged with the hub when the speed of the turbine increases above a predetermined speed. 13. The turbine of claim 7, wherein the drag force is applied near the inlet of the segment, and the lift force is applied between the inlet and the outlet opening of the segment. 14. The turbine of claim 7, further comprising: a second segment; anda third segment wherein the segment, the second segment and the third segment are attached to the shaft. 15. The turbine of claim 14, wherein the segment, the second segment and the third segment are attached symmetrically around the shaft. 16. The turbine of claim 15, wherein the segment has a first mouth, the second segment has a second mouth and the third segment has a third mouth and wherein the segment, the second segment, and the third segment are attached to the shaft such that an angle between the first mouth and the second mouth is equal to an angle between the first mouth and the third mouth. 17. A segment for a fluid driven turbine, comprising: a channel comprising an inlet end and an outlet end opening, the outlet end opening where fluid moving through the segment exits the segment, the cross-sectional area of the channel continuously reducing from the inlet end to the outlet end opening, the channel having a first portion that creates a drag force when fluid moves through the first portion, a second portion that creates a lift force when fluid moves through the second portion, and a third portion that creates a jet force at the outlet end opening as the fluid exits the segment. 18. The segment of claim 17, the channel comprising a top wall and a bottom wall, the top wall parallel to the bottom wall.
