    摘要： The proposed invention is a direct drive converter of sea waves energy in electrical energy. It comprises a closed floating hull (1) and a weighted platform (2) within, equipped with coils and inductors respectively. The hull moves relatively to the platform upon facing the sea waves and electric current is induced in the coils. Hence, the sea waves energy is directly converted in electrical energy, avoiding energy losses on intermediate systems for the conversion. Also, the proposed invention incurs in more types of motion than other direct drive sea waves converters and is completely closed.

    摘要： A buoyant hydrodynamic pump is disclosed that can float on a surface of a body of water over which waves tend to pass. The pump incorporates an open-bottomed tube with a constriction. The tube partially encloses a substantial volume of water with which the tube's constriction interacts, creating and/or amplifying oscillations therein in response to wave action. Wave-driven oscillations result in periodic upward ejections of portions of the water inside the tube that can be collected in a reservoir that is at least partially positioned above the mean water level of the body of water, or pressurized by compressed air or gas, or both. Water within such a reservoir may return to the body of water via a turbine, thereby generating electrical power (making the device a wave engine), or else the device's pumping action can be used for other purposes such as water circulation, propulsion, or cloud seeding.

    摘要： An object of the invention is to provide a power generation system capable of generating electricity at low cost. There is provided a power generation device that generates electricity using a potential energy of a circulation fluid F raised to a predetermined height position by a wave force, the device including: a float 27 that includes a hollow portion 27A; a feeding device 24 that feeds the circulation fluid F toward an upper storage tank 21 at the predetermined height position based on a wave force received by the float 27, the feeding device 24 being accommodated in the hollow portion 27A of the float 27; and a power generation unit 23 that generates the electricity using the potential energy of the circulation fluid F raised to the predetermined height position, wherein a lower portion of the float 27 protrudes such that a cross-sectional area in a horizontal direction decreases as the floating body extends downward, the device further including a storage tank-side accommodation portion 2 that accommodates the float 27, the feeding device 24 and the power generation unit 23.
