Abstract
The present invention relates to the use of marine devices for ocean energy extraction. The invention provides for a rotatable buoy that uses aligned vanes to keep the buoy oriented parallel with the wave front to enable the use of longer buoys, and therefore larger buoys, to increase energy capture for a wave energy converter.
Claims11
A wave energy converter, comprising:
- a sub-surface body;
- a buoy that is disposed above the body and is reciprocally movable along an upright axis relative to the body in response to wave action;
- and
- a shaft that extends downwardly from the buoy into a power take off mechanism within the body and is movable with the buoy along the upright axis to drive reciprocal motion within the power take off mechanism to convert wave energy for industrial uses;
- and
- wherein the buoy is rotatable relative to the body about the upright axis, the buoy comprising one or more aligned vanes, the vanes being long enough to extend sufficiently deep from the buoy to be always partly or fully submerged below the water-surface.
