Wave Energy Converter

A self-reacting and floating wave energy converter for extracting electrical energy from wave motion in a body of liquid comprising:

• an active float that is arranged to float substantially toward or on the surface of the liquid, and being arranged to both heave and surge in response to wave motion acting on the active float;
• an elongate reactive body longitudinally extending between a top end and a bottom end, and having a center of mass located at or toward its bottom end and below its center of buoyancy such that it is arranged to be suspended in a substantially upright vertical position and substantially submerged state into the liquid below the surface, and the reactive body having sufficient surface area and length extending into the liquid from the surface such that it pitches about a center of rotation located at or toward its bottom end in response to wave motion acting on the reactive body,
• the active float and reactive body being pivotably coupled at or toward the top end of the reactive body for pivotable movement relative to each other about a single pivot axis in response to heaving and surging of the active float and pitching of the reactive body caused by wave motion in the body of liquid;
• and
• a power output system that is operatively driven by the pivotable movement about the pivot axis to generate electrical energy.
