ABSTRACT:
A device and method of converting tidal currents into power. The device comprises a plurality of modules and is mounted in tidal water so that one face is presented inland and the opposite face is presented seaward. Each module comprises a turbine mounted on an elevator means which moves the turbine vertically in response to water level changes during a tide. The modules are alternately presented toward the inland and seaward directions thereby permitting tidal water movement associated with both flood and ebb tides to be converted into power. Apparatus for sensing the amount of water flowing over the turbine for controlling the movement of the elevator device, and apparatus for withdrawing power from the device are also disclosed.
