An energy concentration device includes a pneumatic cylinder that allows for contact with waving sea water of the nature to make a float device to drive a piston rod to achieve an effect of up and down piston movement so as to realize an effect of pressurization of air inside the pneumatic cylinder, whereby the air may achieve an effect of increase of pressurization level through multi-staged pressurization and an effect of accumulation by being stored in a high-pressure air storage device for the purposes of electrical power generation with the pressurized air and supplying pneumatic power required by other applications, such as automobiles, motorcycles, buses, and factories and also for supplying of pneumatic power to household devices, such as household appliances and pneumatically-operating doors.

An absorber unit for absorption of wave energy from a body of water comprises a pivoting absorber element with a front end around which the absorber element reciprocates between turning positions. The absorber unit has a frame structure defining an absorber chamber and is at rest with respect to the body of water. The frame structure pivotally supports the absorber element within the absorber chamber from a horizontal front pivot axis above an average surface level of the body of water, wherein the absorber element in an idle position under still water conditions is partially submerged, with an idle draft of the absorber element being determined by the depth of submersion of the lower rear edge below the average surface level. A bottom plate attached to the frame structure has a front portion arranged underneath the absorber element and an upwardly projecting rear portion aft of the absorber element.

A system and method for moving water up a water column to achieve a sufficient pressure to overcome a reverse osmosis filter. The system includes a rigid outer column for receiving and holding water, with an inner, deformable hose located inside the rigid outer column. The hose has a one-way valve at a distal end of the hose to allow water to enter the hose and an outlet at the proximal end of the hose to allow water to exit the hose. A water-raising device to raise the water within the inner, deformable can include a system that moves sections of water within an inner lumen using a peristaltic motion to drive water upwardly through the inner lumen.

A wave-driven power generation system that uses a motor reducer to turn a rocker bar in biasing float boards alternatively up and down, causing creation of water waves in water reservoirs and simultaneously driving transmission mechanisms to move power generators through inertia wheel sets, and thus, the power generators are driven to generate electricity.

A wave barrier or wave terminator type ocean wave energy converter (WEC) utilizing one or multiple adjacent floats together forming an elongated wave front parallel (EWFP) float rotatably connected by at least one swing or drive arm to a secondary floating or shore or seabed fixed body or frame, such that the at least one swing arm is rotating about a submerged pivot point or axle on such body or frame and constraining the motion of the float(s) relative to the body or frame when wave forces are applied against the float(s). Relative to the direction of oncoming wave fronts and relative to the still water line (SWL), the at least one EWFP float is substantially forward of, and above, the pivot point such that the float concurrently moves both upward and rearward on wave crests and returns both forward and downward on ensuing wave troughs. The rear surface of the EWFP float is substantially arcuate and concave with a radius approximating its distance from the pivot point such that the float produces minimal energy consuming back waves when it is being moved by oncoming wave forces. The lower rear arcuate surface of the float can extend below the bottom of the float deeper into the water column to capture additional wave energy.

A wave energy converter includes a float that includes an air chamber that includes a generator that is arranged between the float and a shaft, and that is configured to generate electrical power when the float rotates relative to the shaft, and an elongate spacer configured to connect the float to an anchoring at, on or to a floor of a water body. The float is configured to rotate as the shaft moves along the elongate spacer due to waves and/or tidal movement of the water body. The air chamber includes the shaft that is rotatably suspended inside the float and having a holder configured to substantially arrest the shaft against rotation as the float rotates around the shaft. The shaft is completely arranged inside the float, and the air chamber shields the shaft and the generator off from the water body.

A power generation system is provided. The power generation system includes a floating body, a transmission device, a transportation tank, an upper container, and a power generator unit. The transmission device is driven by a tidal force or a buoyant force through the floating body to lift up the transportation tank to a first position, which is near to the upper container, or to lower the transportation tank down to a second position, which is at a lower level than that of the electric motor to recycle the solid particles. The upper container for carrying a plurality of solid particles is disposed at a higher level than that of the power generator unit, and is used to store and release the solid particles to drive the power generator unit to generate electric power.

A wave energy capturing device arranged to capture and convert wave energy to useful energy when positioned in an operating mode. The device includes a pivot point and a buoyant wave energy absorber affixed to the pivot point. The device has an operating mode where the device is arranged to capture wave energy. In the operating mode the pivot point is supported above the surface of a body of water and is held substantially stationary relative to wave movement. The buoyant absorber is engaged with the surface of the body of water at an operating location positioned downwave of the pivot point and wherein the absorber is arranged to rotate about the pivot point. The rotation defining a rotation arc of the absorber along which the absorber is arranged to reciprocate in the operating mode. The disclosure aims to provide improved capture of wave energy for conversion to useful energy.

A wave energy converter apparatus comprising a floatable wave receiver unit with first and second chambers that extend and retract in response to wave motion, a power conversion and generation module disposed on a float unit that floats in the body of water and a connection assembly connecting the wave receiver unit to the power conversion and generation module. The second chamber includes an open front end to hold the first chamber, allowing partial horizontal axial movement. The assembly includes a hydraulic cylinder and a connecting structure that transfer wave motion energy to the cylinder. As the first chamber moves forward into the second chamber, the hydraulic fluid in the cylinder becomes pressurized. The pressurized fluid powers the hydraulic motor, which in turn drives the generator. A flexible corrugated shield surrounds the side panels of both chambers to prevent water entry.

A reactive blade turbine system works vertically, horizontally, or at an angle and clockwise or counterclockwise according to blade angle and locking position and adjusts to variations in fluid flow such as changes in tidal currents to generate power more efficiently regardless of direction of fluid flow. A method for generating electrical power from a continuous fluid flow via the reactive turbine system is also provided herein.
