Abstract
An ocean wave energy conversion apparatus includes a float adapted to ride on the surface of the ocean in reciprocal vertical motion in response to ocean wave front action and a lever adapted to ride on the surface of the ocean. The lever has one end coupled to the float. A fulcrum pivotally supports the lever. A magnet is coupled to the other end of the lever. Parallel stator cores having electric coils wound thereon together with the magnet form a magnetic circuit. Springs are adjacent the magnet and interconnected to the lever and the magnet. A barrier is disposed between adjacent stator cores. The upward motion of the float caused by impact of waves will move the magnet downward by the lever and compresses the springs. Downward motion of the float will move the magnet upward by the lever and expand the springs. Repeated movement of the magnet will induce a voltage in the electric coils.
