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.
Claims44
A water-wave propulsion mechanism that obstructs or redirects wave motion in a manner that results in a forward thrust and propulsion of a buoyant vessel, the water-wave propulsion mechanism comprising:
- a shroud having a nominally vertical plane of symmetry or a nominally vertical longitudinal axis of approximate radial symmetry, wherein the shroud obstructs the motion of a wave impinging upon the shroud, thereby causing a portion of the power of that wave to be redirected into the forward thrust and a resulting forward propulsive force.
A water-wave propulsion mechanism that obstructs or redirects wave motion in a manner that results in a forward thrust and propulsion of a buoyant vessel, the water-wave propulsion mechanism comprising:
- a shroud having a nominally vertical plane of symmetry, wherein the shroud is directly attached to a chamber at an approximate first end of the shroud, wherein the shroud obstructs the motion of a wave impinging upon the shroud, thereby causing a portion of the power of that wave to be redirected into the forward thrust and a resulting forward propulsive force.
A buoyant apparatus, comprising:
- a first chamber with a first cutout;
- a shroud with a first end and a second end, wherein the first end is directly attached to the first chamber, and wherein the first end is at least partially within the first cutout;
- and
- a second chamber with a second cutout directly attached to the second end of the shroud, and wherein the second end of the shroud is at least partially within the second cutout.
