摘要： An energy harnessing device comprising a substantially helical conduit which in use is arranged to float in a body of water including regions of varying pressure, which may for example arise due to wave motion, tidal motion and/or current flow. The conduit defines a fluid flow path along its length and comprises a fluid inlet and a fluid outlet in fluid communication via said fluid flow path. The conduit is arranged to rotate about its longitudinal axis by the action of water of varying pressure contacting the helical conduit and driving fluid(s) along the fluid flow path. A method of harnessing energy from a body of water including regions of varying pressure is also described.

摘要： New and improved methods and means are described for the efficient, expeditions, economical and safe conversion to usable form of almost all subsurface wave energy available within a predetermined annular region spanned by an array of submerged wave energy removing impellers (28, 30, 50) mounted upon an annular outrigger (3) surrounding and secured to a seagoing central platform. Maximal progressive inward attenuation of practically any state of the open sea is achieved over a very broad wave frequency band by buoyant, nonbuoyant, and neutrally buoyant impellers that function approximately as generalized simple pendulums whose natural frequencies fall at regular intervals throughout that frequency band. Optimal functioning of the impellers is achieved by assigning to their working members (38, 40) suitable degrees of omnidirectional response to water movement drag and inertial forces, respectively. After conversion by pumps (46), the extracted wave energy is conveyed via a pressure transmission subsystem to a central turbine (12) for further conversion and subsequent storage and/or product processing within the central platform.
