Abstract: In certain embodiments, an ocean wave energy extraction system including a wave energy panel may capture kinetic energy from an ocean wave as a force applied to a flexible membrane that drives the WEP back and forth in a reciprocating motion. The WEP dimensions may be selected so that the energy extracted from the wave is maximized and the added mass is minimized. A flexible membrane may be supported on two opposite edges by structural members that may pivot about a base. The shape of the flexible membrane may reciprocate in response to alternating horizontal wave orbital velocities. The force applied to the flexible membrane may be transmitted through the structural members to a power extraction device, such as a hydraulic pump or an electrical generator, that may be mounted to the base. Multiple WEPs may be arranged parallel to the wave crest to produce additional power.
