摘要： A bottom-hinged wave energy converter (WEC) comprising
- a foundation (10) defining an apparent foundation weight;
- a power converter (20) connected to the foundation (10), the power converter (20) comprises a crank (22);
- a flap arm (30) comprising along an arm axis (32) a crank end (34) connected to the crank (22) and a flap end (36);
- a flap (40) comprising a flap bottom (42) connected to the flap end (36), and a flap top (44) adapted to be at or near an ocean surface (102) during use, the flap (40) comprising a substantially circular or elliptic flap cross-section (46) in a cross-section plane (48) substantially perpendicular to the arm axis (32), which flap cross-section (46) is constant between or increases between the flap bottom (42) and the flap top (44) thereby defining a flap buoyancy, wherein the apparent foundation weight being lesser or greater than the flap buoyancy.-

摘要： A water flow power generation device includes a supporting frame, a carrying platform, a power generation assembly, a speed-increasing gear box and an impeller blade assembly, wherein the supporting frame is located on one side of water flow, the carrying platform is arranged on the supporting frame, and the power generation assembly, the speed-increasing gear box and the impeller blade assembly are arranged on the carrying platform, the impeller blade assembly includes a rotating shaft connected with the speed-increasing gear box and a plurality of impeller blades uniformly arranged at one end of the rotating shaft away from the peed-increasing gear box, the impeller blades are in contact with the water flow and are driven by the water flow to rotate. The carrying platform can be adjusted to move up and down, so that the contact area of the impeller blade assembly and the water flow is adjusted, water energy can be utilized to the maximum extent, and the service life of the impeller blade assembly is prolonged. The water flow power generation device is able to greatly simplify the complexity of a hydroelectric generation system, the manufacturing cost is reduced, and industrialization popularization is easier to achieve.

摘要： Apparatus and method for extracting at least hydrostatic energy from sea waves, the apparatus comprises:
-at least one first compartment being in fluid communication with at least one second compartment via a manifold having an internal volume filled with a liquid, each of the compartments having an internal volume being variable between a first internal volume, and a second internal volume being smaller than the first internal volume;
wherein the apparatus holds a total volume of liquid that is larger than a volume of liquid within the manifold, but less than a sum of the volume of the liquid within the manifold and a total first volume of the at least one first compartment and the at least one second compartment, and
wherein the volume of liquid within the manifold is larger than the total volume of liquid within the at least one first compartment and the at least one second compartment.-

摘要： This invention relates to a wave energy recovery apparatus with a power-take-off arrangement comprising at least a base (1), a reciprocating panel (2), two power-take-off (PTO) units (6) with one or more generators (14) to convert kinetic energy of waves or tidal currents to electricity, at least two gear transmissions operatively connected between the panel (2) and the generators (14) and at least two one-way clutch mechanisms (10) to control the directions of rotation of the generators (14). The panel (2) is arranged to rotate a half of the generators (14) when rotating into one direction and another half of the generators when rotating into the opposite direction.
