摘要： A wave energy harnessing converter (1) has a tube (3) which floats on the sea. A water inlet (2) delivers water to the tube, and an air inlet (2) delivers air to the tube (3). The tube has sufficient buoyancy and flexibility to float on the water and conform to the shape of waves when the tube extends substantially in the direction of travel of the waves, causing water in the tube to be conveyed from the inlet and to be pressurised and the air to be compressed in a series of moving air pockets. The tube is reinforced to minimise energy losses through distortion or elongation. A converter output section (10) for receiving water and compressed air from the tube (3) for providing energy.

摘要： A wave energy converter (100) has floating elements (101) having buoyancy to pitch up and down with wave movement. A connector links the element to a prime mover (102). A tilt means enhances tilting motion of a fore element end upwards with a wave crest and an aft element end downward with a wave trough. The tilt means may include fins (103) mounted at different fore-aft positions on the elements, each fin being arranged in a configuration extending from the fore end downwardly towards the aft end. The tilt means may include air pockets (510) which move in a switching manner between the fore and aft ends to provide bi-stable positions.

摘要： An air and water intake (1) for a wave energy converter has a substantially rigid hollow body (20) having a mouth (4, 5) for receiving water from the upper parts of the waves and air, and an outlet for delivering the water and air to a wave energy converter. There is a buoyancy means (10) for providing buoyancy to the body (20) for causing the intake to receive into the mouth skimmed-off water from near the top of a wave, and to tilt so that said water flows downwardly within the body, gaining velocity. The intake comprises a connector (15) on an underside of the body for connection to an anchor at a location for pitching of the intake body about a pitching axis. The pitching axis (40) and a lateral centre of buoyancy axis (41) are arranged such that water primarily from the top of a wave and slightly forwardly of a wave crest is received. The buoyancy is arranged such that the centre of buoyancy axis (41) of the intake is forwardly of the pitching axis (40).

摘要： A wave energy converter has blades (54, 56, 57, 59) on frames (51, 52) rotating about a pivot joint (53) on a structure (4, 52, 502, 505, 86). There is reciprocating rotary motion of the frame with respect to the structure, providing reciprocating rotary input power to a mechanism (73, 94, 98). The mechanism (98) may be arranged so that the reciprocating input power is transferred to uni-directional power via pulleys (101, 106) and sprag clutches (102, 107).

摘要： A wave energy converter (1) has a water inlet system (2) comprising a channel (4) having a mouth (4) to receive slugs of water and being connected (10) to a mooring to tilt in a pitching action to receive and accelerate water slugs. The water slugs are delivered to a whirlpool system (3), and this aggregates energy from said water in a vortex. The whirlpool has a cylindrical configuration with a domed lower portion. There is a turbine (36) below the whirlpool bowl (30), and the blades (270) are C-shaped, with the convex side facing the direction of travel. There is a pair of pitching buoys (12) on the channel (4). These are pivotally connected to a mooring frame (10) and are separately pivotally connected to the channel (4) by a spaced-apart pivot joint (13). This provides a buoyant fulcrum effect to achieve greater lift of the front of the channel (4).
