ABSTRACT:
An apparatus for harvesting wave energy by utilizing the movement of the waves has a support or foundation suitably anchored so as to be relatively stable to wave movement. Pivotally attaching to the support is a pontoon member. The pontoon is so pivoted on the support that it moves in respect to the support in response to wave movement. The interior of the pontoon is partitioned to include two chambers, one located at each end of the pontoon. Each of the chambers includes a gas inlet and a gas outlet which are equipped with one way valves which restrict gas flow into the chambers via the inlet and out of the chambers via the outlet. A gas collecting system is attached to the gas outlet. The two chambers are connected together near the bottom of the pontoon by a connecting member. A movable member within the interior of the pontoon which is operatively associated with the connection member moves in response to wave movement. The moving member seals the connecting member between the two chambers and as it moves it increases gas pressure in the chamber which it is moving towards causing gas to exit from that chamber out of the gas outlet and simultaneously decreases pressure from the other chamber causing gas to be drawn into the chamber through its gas inlet.
