An underwater power generation system (10) that has a line member (30) that moves along a defined pathway. A number of foils (40) drive the line member using the flow of a water current. The defined pathway lies in a plane that is substantially perpendicular to the flow of water current. A power take-off (114, 124) is connected to the line to produce power.

What is claimed is: 1. A power generation system adapted to provide power output from water flow, the system comprising: a frame; a plurality of carriages linked in series along a pathway, the pathway lying substantially in a plane; a track supporting the carriages and being attached to the frame,
What is claimed is: 1. A power generation system adapted to provide power output from water flow, the system comprising: a frame; a plurality of carriages linked in series along a pathway, the pathway lying substantially in a plane; a track supporting the carriages and being attached to the frame, wherein the track comprises a rectangular channel having opposing side track plates and a bottom track plate, and wherein the carriage comprises a body, a first wheel assembly having a pair of wheels, each wheel adapted to roll along an edge of one of the side track plates and a second wheel assembly having a wheel adapted to roll along an inner surface of one of the side track plates; a plurality of foils, each mounted on one of the plurality of carriages, wherein the foils are adapted to propel the carriages along the pathway in response to water flow acting on the foils in a direction substantially perpendicular to the plane, wherein each of the foils is formed from two splayed wings and a connection arm; and a power take-off operatively adapted to extract power from the movement of the carriages along the pathway. 2. The power generation system of claim 1, further comprising a drive chain connecting the plurality of carriages and operatively associating the carriages with the pox or take-off. 3. The power generation system of claim 1, wherein the channel further comprises a lubricating strip arranged on one of the side track plates adjacent the wheel of the second wheel assembly, the lubricating strip adapted to retain the wheel in the channel. 4. The power generation system of claim 3, wherein the wheels of the first wheel assembly are grooved so as to receive the edge of the side track plate. 5. The power generation system of claim 4, wherein the carriage comprises two of the first wheel assemblies and two of the second wheel assemblies. 6. The power generation system of claim 1, further comprising an anchor for mounting the system on an ocean floor or river bed. 7. The power generation system of claim 6, wherein the frame comprises a main cylindrical body with two arcuate attachment anns, the attachment arms mounted to the anchor. 8. The power generation system of claim 7, wherein the frame further comprises a plurality of track support members extending from the cylindrical body, the track support members supporting the track. 9. The power generation system of claim 1, wherein the pathway is generally obround in shape. 10. The power generation system of claim 1, wherein the power take-off is operatively associated with a generator for producing electricity. 11. The power generation system of claim 1, wherein the power take-off is operatively associated with a pump for pumping water. 12. A device for power generation comprising a first and second power generation system of claim 1, the first power generation system mounted adjacent to the second power generation system, wherein foils of the first power generation system rotate in a direction opposite to rotation of the foils of the second power generation system in response to substantially perpendicular water flow to the respective power generation system. 13. The power generation system according to claim 1, wherein each carriage has a foil mounted thereon. 14. A method of generating power from water current comprising: (i) providing a power generation system comprising: a frame; a plurality of carriages linked in series along a pathway, the pathway lying substantially in a plane; a track supporting the carriages and being attached to the frame, wherein the track comprises a rectangular channel having opposing side track plates and a bottom track plate, wherein the carriages comprise a body, a first wheel assembly having a pair of wheels, each wheel adapted to roll along an edge of one of the side track plates and a second wheel assembly having a wheel adapted to roll along an inner surface of one of the side track plates; a plurality of foils, each mounted on one of the plurality of carriages, wherein the foils are adapted to propel the carriages along the pathway in response to water flow acting on the foils in a direction substantially perpendicular to the plane, wherein each of the foils is formed from two splayed wings and a connection arm; and a power take-off operatively adapted to extract power from the movement of the carriages along the pathway; (ii) arranging the power generation system in a water current, wherein the water flows in a direction substantially perpendicular to the plane; (iii) allowing the ater to flow through the power generation system to propel the carriages along the track; and (iv) extracting power from the power take-off. 15. The method of generating power according to claim 14, wherein the power generation system is arranged in an ocean. 16. The method of generating power according to claim 14, wherein the power generation system is arranged in a river. 17. The method of generating power according claim 14, wherein the power take-off is operatively associated with a generator for producing electricity. 18. The method of generating power according to claim 17, wherein the power take-off is operatively associated with a pump for pumping water. 19. The method of generating power according to claim 14, wherein each carriage has a foil mounted thereon.
