A buoy for use in reducing the amplitude of waves in water and a system making use of plural buoys to create a floating breakwater. Each buoy is arranged to be constrained, e.g., connected to an anchor, and comprising a body e.g., a cylindrical member having at least one outwardly projecting fin, that is configured to be resonant and impedance matched. The buoy and anchoring approach allows for self-tuning to the chances in the wave spectrum due to the tidal or storm surge induced changes in the water depth. The body of the floating buoy is not limited to circular cylinder, and could be square, hexagonal, triangular, etc but must have at least one exterior mounted fin.

The present invention relates to a wave power generating apparatus which drives a generator using the tidal motion and wave energy of the tide to produce electrical energy. More particularly, the present invention relates to a wave power generating apparatus which generates power by transferring rotating force to a power-transmission shaft when a float moves upward by means of the upward and downward motion of a wave, and which generates power by transferring the motive energy of the float produced by the lateral force of the wave.

A device and method for producing rotational mechanical power is disclosed which has a plurality of hinged blades attached to a central circular hub. The device may be used to convert the kinetic energy from the movement of the wind, ocean or river currents, or tidal flows into useful rotational mechanical power. The rotational mechanical power may be converted into electrical energy. Each of the plurality of blades are attached to the central circular hub via a hinge. Each blade is also fitted with a blade limiter to restrict its motion to no more than 90° relative range from the tangent line to the central hub at the point where the blade attaches to the hub. The hinges and blade limiters allow the blades to both present a surface automatically to the motive natural fluid and to generate the maximum torque in one side and minimum resistance torque positions in the opposite side relative to the motion of the motive stream. The resultant blades relative position creates a torque differential from one side of the central hub to the other causing the hub to rotate. The central hub will rotate in the same direction regardless of the direction of flow of the natural motive stream.

The invention relates to a flow-guiding and energy-gathered type sea wave, tide, ocean current and wind power four-in-one power generation system. A base is arranged below the sea wave level and provided with a plurality of arc flow guiding plates which are evenly distributed along the circumference. The lower ends of supporting rods are connected with the arc flow guiding plates, and the upper ends of the supporting rods are connected with a platform. An accelerating machine is arranged on the platform, the upper end of a transmission pipe is in transmission with the accelerating machine, and the lower end of the transmission pipe penetrates through the platform and then is connected with a bearing; the bearing is arranged on the base. A plurality of fan blades and impellers are evenly distributed on the transmission pipe, and the impellers are located below the fan blades. The vertical end of one side of each arc flow guiding plate is close to the impellers, and the vertical end of the other side of each arc flow guiding plate is close to the outer edge of the base. A generator is arranged at the upper end of the accelerating machine and is in transmission with the accelerating machine. One end of a cable is connected with the generator, and the other end of the cable sequentially penetrates through the transmission pipe and the bearing and then is connected with a cable connector in the base. The power generation system has the beneficial effects that sea waves, tides, ocean currents and wind power act together to achieve high-power electricity generation, and sea water or wind power also can be used for independently generating power.

A system for converting marine surface wave energy into electric energy includes a barrier disposed generally vertically and having at least a portion thereof disposed above a surface of a body of water. The portion has a substantially planar surface disposed generally transverse to direction of marine surface waves. Bottom edge of the barrier is pivotally connected to one of a floor bed, a rigid formation and a rigid structure. At least one linear electric generator is coupled to storage of electric energy and is operable by a pivotal movement of the barrier. One type of electric generator is disposed external to the barrier while another type is mounted within a barrier chamber.

Disclosed herein are a tidal power generating module and a tidal power generating method using the same. The tidal power generating module continuously generates power using compressed air and weight of seawater even at high tide and low tide at which the level of the seawater is not fluctuated in addition to the vertical movement of a vertical movement unit due to the rise and fall of the tide.

A wind and water power generator ship. A waterpower generation unit generates electricity using a difference between the ebb and the flow of the tides, and is provided with a buoyant body that produces buoyancy, which enables the waterpower generation unit to float on water. A center shaft is mounted on a base on an upper end of the waterpower generation unit, and is rotatably supported by a bearing. A wind power generation unit generates electricity using wind power, is provided on an upper end of the center shaft, and is rotatable depending on a direction of wind. The distance from a front end of the wind power generation unit to the center shaft is shorter than the distance from the center shaft to a rear end of the wind power generation unit.

An ocean energy harvesting system utilizes horizontal structural members that rotate in response to wave motion. The structural members are designed to capture energy in a line array that replicates the shape of the waves as they pass through the ocean. A generator platform is placed in the ocean environment or on the shore, and the structural members rotate under the platform or around a pivot post placed in proximity to the platform. The rotation drives a generator shaft due to direct attachment to the structural member or from a cable attached to a structural member some distance from the platform. The structural members can be of substantial length depending on the prevailing wave conditions at the site and the desired amount of energy capture. The system adjusts to differing water levels due to tidal shifts.
