ABSTRACT:
Accordingly, the system for extracting power from tidal or other water action in a water region having a bottom surface, comprises: a base assembly positionable on the bottom surface of the water region; a buoyant blade assembly mounted on the base assembly, the blade assembly including at least one buoyant blade member, wherein the blade assembly or the blade member is capable of oscillating through an angle, wherein the buoyant blade member is mounted such that when the base assembly is positioned properly in the water region relative to the direction of the tide or other water action, torque is generated by the oscillating movement of the buoyant blade assembly or the buoyant blade member, and wherein the base assembly includes a power-extracting mechanism responsive to the torque generated by the tide or other action of water or the buoyant blade assembly; and a system for coupling the torque to the power-extracting mechanism.
