An apparatus that floats at the surface of a body of water over which waves pass, causing a nominally vertical axis of the apparatus to tilt away from an axis normal to the resting surface of the body of water. Tilting allows a fluid to flow through a channel that in an un-tilted apparatus would require the gravitational potential energy of the fluid to increase (i.e., to flow uphill), but, because of the tilt allows the fluid to flow through the channel in a downhill direction. Successive wave-driven tilts of the apparatus incrementally raise water to a head from which a portion of its gravitational potential energy can be converted to electrical power by causing the water to return to a lower level by flowing through a water turbine, or through some other apparatus that performs a useful function when supplied with a flow of high-pressure water.

A drive assembly is provided suitable for aiding in the conversion of wave energy to useful energy. The drive assembly of the present invention is arranged to transfer wave energy to an energy converter, the drive assembly comprising a wave energy capturing member; and a lever arm coupled to the wave energy capturing member, the lever arm being movable between a first stroke position and a second stroke position to define a working stroke; wherein the lever arm is arranged to be coupled to an energy converter and is further arranged to transfer energy from the wave energy capturing member to said energy converter; further wherein the wave energy capturing member is arranged to move the lever arm between the first stroke position and the second stroke position; and wherein the first stroke position and the second stroke position define distal end points of the working stroke; the working stroke arranged so as to drive said energy converter.

This invention describes the electrical power generation in a sustainable way, by means of a device, which is installed in the downpipes of rainwater collected by the building roofs, capable of transforming the potential energy present in said rainwater runoff into electrical power, where the generated energy is stored in batteries or fed into the utility network.

A kinetic fluid energy conversion system comprises one or more hubs which rotate about a central hub carrier, each including one or more independently controlled articulating energy conversion plates (“ECP”). An articulation control system rotates each ECP independently of all others to control its orientation with respect to the fluid flow direction between an orientation of 90° perpendicular to the fluid flow, while traveling in the direction of the flow and 0° minimal drag parallel position to the flow, while traveling in the direction against the flow or blocked from it. Each hub can be operably coupled to another hub to form one or more counter-rotating hub and ECP assemblies whereby the mechanical energy is transferred through the hubs, to one or more clutch/gearbox/generator/pump assemblies thereby permitting such assemblies to be land-based when the system is air-powered, and above or near the surface, when the system is water-powered.

A floating mooring system for a single CycWEC applies counter forces and torques to keep a generator suitably stationary for power generation without requiring fixed attachments to the ocean floor or requiring a large frame interconnecting multiple CycWECs. The mooring system uses floats or floatation structure with differential ballasting to counter operating torque and drag plates to counter reactive forces. The floatation structures may be used to float the CycWEC for transport to a deployment location, where changing the overall ballasting of the floatation structures submerges the CycWEC to a desired depth and differential ballasting in the floatation structures counts expected operating torques.

A wave power generation unit suitable for large-scale application and a system thereof are disclosed. The wave power generation unit includes at least two types of water platforms that dynamically differ from each other under the effect of waves: stationary floating platform and movable floating platform. The two types of floating platforms are paired to form a functional unit, and the difference between the two floating platforms caused by waves causes interactions between the two floating platforms. The movable floating platform converts wave energy into mechanical energy, and the stationary floating platform converts machinery energy into electrical energy. The dynamic features of the floating platform are adjusted by a sink and float control device or a peripheral lifting device, and the adjustment effect is enhanced by a large-mass flywheel. Multiple wave power generation units form a wave power generation system.
