Title:
WAVE ENERGY CONVERTER
Document Type and Number:
WIPO Patent Application WO2008063086
Kind Code:
A9
Abstract:
A wave energy converter (10) for extracting useful energy from wave motion. The converter (10) comprises an active float (12) that is arranged to float on the water, and being arranged to heave and surge in response to wave motion acting on the active float, and an elongate reactive body (14) that is arranged to be suspended in a substantially submerged state into the water and having sufficient surface area and length such that it pitches in response to wave motion- acting on the reactive body. The active float (12) and reactive body (14) are pivotably coupled for pivotable movement relative to each other about a single pivot axis (16) in response to heaving and surging of the active float and pitching of the reactive body. The converter also comprises a power output system that is driven by the pivotable movement about the pivot axis to capture the useful energy.
