ABSTRACT:
An apparatus for converting the energy contained in the wave motion of a body of water to alternate forms of energy. The apparatus comprises a main water pipeline, a water inlet for directing water into the main water pipeline from a plurality of water inlet positions along a path in the direction of wave propagation. A vertical water flow riser is connected to, and receives water from, one end of the main water pipeline. The flow riser includes a cylinder and sealed piston arrangement, the piston movable upwardly in the cylinder responsive to the positive pressure of incoming water beneath the piston, and movable downwardly in the cylinder under the influence of gravity acting on the cylinder and on the water in the cylinder beneath the piston. A drain is provided for allowing a regulated amount of water to drain from the main pipeline on the downward stroke of the piston. The piston is coupled to an energy conversion means for producing an alternate energy output on both the upward and downward strokes of the piston.
