A wave energy converter (WEC) buoy includes at least one pitch-driven WEC (“PDWEC”) device. Each PDWEC device includes two reaction masses which are placed at diametrically opposite ends of a container designed to float along the surface of a body of water and to move in response to the pitching motion of the waves. The reaction masses are interconnected so that when one reaction mass moves up, the diametrically opposed reaction mass moves down, and vice-versa. The movement of the reaction masses drives power take off (PTO) devices to produce useful energy. The reaction masses may be interconnected by any suitable linking system. One or more PDWEC device may be combined with a heave responsive device to produce a WEC buoy which can produce a power output in response to pitch or heave motion.

The present disclosure belongs to the technical field of power generators, and in particular relates to a marine support column structure with power generation function. The support column structure solves technical problems that existing marine power generators can only generate power with single energy and have few functions and so on. The marine support column structure with power generation function includes a column body. The support column structure of the present disclosure is capable of generating power with sea wind and waves, and is further capable of serving as a guardrail.

An improved ocean wave energy extraction system is disclosed. The system includes at least one duct for receiving an oscillating water column. The duct has a first segment, a second segment arranged transversely to the first segment and a flow control segment intermediate the first and second segments. The flow control segment is configured to inhibit turbulent flow of the oscillating water column flowing within the duct. A turbine is in fluid communication with the second segment of the duct such that the turbine is driven by the fluid flow which is generated by the oscillations of the oscillating water column within the duct. The turbine rotates an electric generator to thereby generate electrical energy.

Some geographies have tide ranges above 15 yards, but most do not. The wider the tide range, the more hydroelectric power can be generated per cycle of low tide to high tide and then high tide to low tide, using a tidal barrage. Methods of raising the high tide above the measured level to fill the storage ponds to an even higher level and a method to empty the storage ponds to a lower than low tide level, provide means to expand the tide range significantly, enabling many more planet geographies to have economically feasible hydroelectric power.

A gyrating wave power plant, comprising a body (1) floating on water with a main plane which in calm water is substantially vertical. The body is moored in an orientation with the main plane transverse to the propagation direction of waves. The body has its upper and lower sections provided with arched fins (2, 3). The fins (2) in the body's upper section curve downward when proceeding towards side edges of the body, and the fins (3) in the body's lower section curve upward when proceeding towards side edges of the body. The arched shape of the fins (2, 3) is an oval-shaped spiral with respect to a lateral swaying axis (A) of the body, which is perpendicular to the main plane.

Some embodiments of the present disclosure include a water purification system for producing purified water from a body of water. The water purification system may include a floating platform having a ramp extending from an edge thereof at a downward angle into the body of water, a primary impoundment area extending from a top portion of the ramp onto the floating platform, a pair of sub-impoundment areas attached to an end of the primary impoundment area distal from the ramp, at least one hydraulic cylinder and at least one accumulator attached to the sub-impoundment areas, and a nanofiltration system operatively attached to the at least one hydraulic accumulator. Water may be configured to flow from the body of water onto the ramp and through the system, exiting the nanofiltration system as purified water.
