    • A buoyant actuator (19) for coupling wave motion to a device operable in response to wave motion in a body of water. The buoyant actuator (19) comprises a generally spherical body (20) defining an exterior surface and a hollow interior adapted to contain water received from the body of water. The exterior surface comprises a plurality of facets (101) which are tessellated. Typically, there are 36 facets (101), of which 12 comprise generally pentagonal facets (105) and 24 comprise generally hexagonal facets (107). The body (20) comprises a plurality of openings (143) for fluid flow between the hollow interior and the surrounding body of water. A closure configured as a flap (145) is provided for each opening (143) to block or at least inhibit fluid flow therethrough, the closure being adapted to move away from the opening to permit fluid flow therethrough in response to a predetermined fluid pressure differential imposed thereon between the hollow interior and the surrounding body of water. The exterior surface of the body (20) is configured to viscously couple with water surrounding the body (20). The viscous coupling between the surrounding water and the exterior surface of the body (20) provides added effective mass to the buoyant actuator (19) which is additional to the physical mass of the buoyant actuator and the mass of the volume of water contained in the body.

    • Apparatus (10) for harnessing ocean wave energy and for converting the harnessed energy to high pressure sea water, typically above 100 psi and preferably above 800 psi. The high pressure seawater generated by the apparatus (10) can be piped to shore for use in any appropriate purpose. The apparatus (10) comprises a float (12) buoyantly suspended within the body of seawater (1) and a pump (13) operatively connected to the float (12). The pump (13) comprises an intake chamber (47), a discharge chamber (49) and a piston (61) extending between the intake and discharge chambers (47, 49). The piston (61) comprises a tube (63) having a flow passage (102) extending between the intake and discharge chambers (47, 49). The piston (61) and discharge chamber (49) cooperate to define a pumping chamber (100) adapted to undergo expansion and contraction in response to reciprocatory motion of the piston. The piston (61) is operatively connected to the float (12) to be driven by upward movement of the float. The pump may have provision for treatment of the seawater which it delivers through use of an electrolysis process receiving electric current from a linear current generator incorporated in the pump.
    • 用于利用海浪能量并将利用能量转换成高压海水的设备(10),通常高于100psi,优选高于800psi。 由设备(10)产生的高压海水可以被管道输送到岸上以用于任何适当的目的。 装置(10)包括悬浮在海水体(1)的主体内的浮子(12)和可操作地连接到浮子(12)的泵(13)。 泵(13)包括在进气室和排气室(47,49)之间延伸的进气室(47),排放室(49)和活塞(61)。 活塞(61)包括管(63),该管(63)具有在进入和排出室(47,49)之间延伸的流动通道(102)。 活塞(61)和排出室(49)配合以限定适于响应于活塞的往复运动而经历膨胀和收缩的泵送室(100)。 活塞(61)可操作地连接到浮子(12),以通过浮子的向上运动来驱动。 泵可以通过使用从并入泵中的线性电流发生器接收电流的电解过程来提供用于处理其所产生的海水的装置。

    • A buoyant actuator (10) for use in apparatus (11) for harnessing ocean wave energy and for converting the harnessed energy to high-pressure seawater. The buoyant actuator (10) comprises a body (21) defining a chamber (23) having a pliant outer skin (27). The chamber (23) is adapted to contain matter and a hydrodynamic property of the body (21) is selectively variable by varying the matter within the chamber (23). The variation to the hydrodynamic property may comprise a variation to the buoyancy (either positively or negatively) or a variation to the response area (such as the volume or shape) of the body (21), as well as a combination thereof. The variation to the matter may comprise addition of matter to, or extraction of matter from, the chamber (23). The matter may comprise a solid, liquid or gas, as well as any combination thereof. In the arrangement shown, the matter comprises foam spheres (53). The outer skin (27) is drawn into a taut condition by the outward pressure of the foam spheres (53) inside, causing the actuator to assume its design shape. The volume occupied by the foam spheres (53) is in total still less than the total enclosed volume of the chamber (23) and there are interstitial regions (55) around each sphere (53). The interstitial regions (55) may be filled with fluid to adjust the buoyancy.
