Abstract
Disclosed are embodiments of a novel type of wave-powered propulsion adapted for use by buoyant vessels in order to provide or supplement their self-propulsion. An approximately vertical and semi-cylindrical propulsive shroud attached to a vessel interacts with a wave motion at and below the vessel in order to impart a thrust to the vessel.
Claims11
A buoyant apparatus, comprising:
- a wave energy converter comprising an upper bulbous portion fluidly coupled to a lower tubular portion along a longitudinal axis;
- a cuff coupled to the lower tubular portion;
- and
- a shroud attached directly to the upper bulbous portion of the wave energy converter and the cuff, wherein the shroud only partially laterally surrounds the wave energy converter around the longitudinal axis.
