Abstract
A unique point absorber type wave energy conversion device is disclosed that includes a Power Take Off (PTO) which uses a torsion spring to return a vertical shaft to its original position after being rotated by a rope or cord that pulls a reel via a guide system. This spring return allows the PTO and housing to stay stationary under the wave energy while a buoy at the surface provides an oscillating linear movement. The oscillating rotary motion caused by the interaction of the buoy and spring is converted into a one directional motion via a one-way clutch and is transmitted to generators using a gearbox that increases rotational speed.
