Abstract:
A wave energy converter has blades ( 54, 56, 57, 59 ) on frames ( 51, 52 ) rotating about a pivot joint ( 53 ) on a structure ( 4, 52, 502, 505, 86 ). There is reciprocating rotary motion of the frame with respect to the structure, providing reciprocating rotary input power to a mechanism ( 73, 94, 98 ). The mechanism ( 98 ) may be arranged so that the reciprocating input power is transferred to uni-directional power via pulleys ( 101, 106 ) and sprag clutches ( 102, 107 ).

Claim (Index 52):
The wave energy converter as claimed in  claim 45 , wherein the power take off mechanism is mounted on the frame and is linked by a drive member to the structure; and wherein the power take off mechanism comprises a mechanical rectifier to convert mutual reciprocating rotary motion of the frame and the structure to unidirectional rotary motion; and wherein the mechanism comprises a plurality of sprockets or pulleys connected by sprag clutches to a shaft providing output power; and wherein the sprag clutches are arranged so that power is transferred from the sprockets or pulleys to the shafts so that the shafts contribute to driving the prime mover, or are idle, irrespective of direction of rotation of the sprockets or pulleys; and wherein a set of a plurality of the sprockets or pulleys are driven by the same chain or belt, and there is a tensioner wheel for the chain or belt, preferably located between two sprockets or pulleys.
