An apparatus for harnessing the energy derived from the undulatory motion of a body of water includes an assembly having a buoyancy sufficient for maintaining it afloat in the water, a first structure substantially following multidirectional undulatory motions of the water and a second structure mounted in the assembly for free movement in a plurality of planes with respect to the first structure. The second structure is displaceable by gravity and by forces derived from the motions of said first structure. There is further provided a device connected to the first and second structures for generating a pressure output in response to the force derived from the relative motions between the first and second structures. An arrangement is coupled to the pressure output of the device for utilizing, at least indirectly, the energy derived from the pressure output.

A magnetohydrodynamic electric generator for the direct energy conversion of the kinetic energy of saline water flowing through a magnetic field, preferably in the constricted part of a duct. Means may be provided to increase the kinetic energy of the flowing saline water using wave-powered air compressors and/or water pumps. Also described are sea platforms containing a multitude of electricity generators in a configuration to maximize the conversion of the kinetic energy of flowing saline water into electric energy.

Apparatus for converting ocean surface wave energy into useful rotational kinetic energy. A refractive horn and ramp provides reflectionless impedance transformation of ocean surface wave energy at the input to the system. Wave energy, in the form of breakers, which are massive pulses of essentially pure kinetic energy, from the output of the horn/ramp are then smoothed and transformed directly to mechanical rotation. Smoothing is accomplished by the inertial properties of a "liquid flywheel". The rotational kinetic energy may be extracted by means of a turbine to provide useful work. Discharged water is returned to the ambient ocean through a low terminal velocity diffuser. The entire structure may be located offshore and the discharged fluids may be used for auxiliary purposes.

A power generator, utilizing ocean waves as a motivating force, having at least one undershot paddle wheel above a upward sloping gathering platform and at least one paddle wheel arranged below the platform at one end. The upper paddle wheels, arranged to deliver power from incoming waves, and, outgoing waves are arranged to rotate a propeller shaft. The gathering platform guides incoming waves in an undershot action on the wheels and discharges some of the water over the end of the platform in an overshot action on the paddle wheel below the platform.

A power generator, utilizing sea waves as a motivating mechanism, having a rotatable paddle wheel arranged to rotate a propeller shaft, includes a gathering platform to guide incoming wave propelled sea water in an overshot flow onto the paddle wheel and discharging the same into a catch basin which releases impounded sea water, on the wave recession, in an undershot paddle wheel flow to utilize both the incoming and outgoing sea waves as a source of power for the generator.

This invention relates to an artificial reef to be anchored to the seabed, basically comprised of two or more juxtaposed conduits (1) and (2) which are positioned in parallel with the direction of waves propagation, both conduits being provided with directrices (3) and (6), the upper conduit having directrices (3) which drive the flow of the wave's crest (4) converging to the entries (5), the lower conduit also having directrices (6) which drive the water diverging from the exits (8) in the area under the wave's trough (7), all of these apertures being provided with flexible filters made from fabric, which will smoothly control the abrupt reflux of flow. The said conduits are hydraulically connected, each connection comprising a shut-down valve associated to a useful energy-generating unit (9).In case the main components of the device shall not be in direct contact with seawater, the device also comprises pads (11), (12) and (13), which are made from a thin flexible material, such as rubber, and cover all the existing entries (5) and exits (8) in the said conduits, each pad being simultaneously connected to entries and exits in the same vertical line of the same segment of the device, with the conduits and pads being internally filled with a fixed amount of fluid which thus remains fully isolated from the seawater.

This invention has to do with generating electricity by converting kinetic energy embedded in the water in motion such as ocean waves, or river flow, or wind pressure into rotational energy which is to be used to rotate the electricity generator spin axis to generate electricity. To achieve this goal, Moving Window Frame with multiple Vertical Windows and with or without a Horizontal Window is invented.
摘要:
An arrangement for concentrating sea waves, includes a grid-like structure of stopping and/or delaying elements adapted to influence the amplitude and/or phase of the waves and located in such positions in the water that the elements in interaction with the incident sea waves form an interference pattern which gives a concentration of the wave energy in a limited area (concentration area). When the wave energy is to be utilized for power production, the grid-like element structure is designed to give a concentration of the wave energy in a concentration area located in the short-range field of the element structure. Preferably the elements in the structure are mainly situated in front of the concentration area with respect to the dominant wave incident directions. Moreover, the element structure may have an extension (aperture) which is substantially larger than the wave length of the dominant waves at the location.
