Abstract:
1. A tidal power station device for exploiting energy from a tidal flow, said tidal power station device comprising: a first anchor means anchored at a first location and a second anchor means anchored at a second location that is a distance from said first location, said first location and said second location being submerged in a body of water having a tidal flow; a sail submerged in said body of water; and a transport means having a first end at said first anchor means and a second end at said second anchor means, said transport means for transporting said sail along a path between said first end and said second end and for coupling to an electric generator; wherein, when said tidal flow flows in a first direction, said sail is forced along said path by said tidal flow in said first direction, and when said tidal flow flows in a second direction that is reverse of said first direction, said sail is forced along said path by said tidal flow in said second direction.
