A wave power generation device of the present invention includes: a buoy floating on the sea; a power generator generating electrical energy or hydraulic energy; a power transmitter connecting the buoy and the power generator to each other; and a wire having a first end and a second end connected to the buoy or the power transmitter and changing in tension by motions of the buoy.

A wave energy conversion (WEC) system includes a float body, a heave plate, a tether, and a controller. The tether couples the heave plate to the float body. The controller controls the tether between survivability modes. Each survivability mode adjusts a tension and/or length of the tether.

Device for converting mechanical energy from sea waves into electric energy including at least a float and two rigid rods. The rods are preferably anchored to the seabed at one end, and to the float at another end. There are also two ballasts that effect their weight towards the sea bed to keep the free ends of the rods constantly in traction and free to rotate around their hinges. The float oscillates up and down along a vertical line due to waves. There are at least two cables that connect the free ends of the rods to a transmission shaft of a generator positioned along the vertical line so that the vertical, horizontal, or rotary oscillatory motion of the float caused by the waves generates an oscillatory motion of the rods which are pivoted on their respective hinges, and thus transfers rotary motion to the transmission shaft of the generator.

Device for conversion of wave energy into electrical energy and the process for its deployment at the exploitation location, wherein the device comprises a supporting construction composed of buoyancy elements and having a supporting tube attached on the upper side. The device comprises a joint gear on the inner circumference connected with the outside surface of the supporting tube in a sliding manner and a sphere to which is the floating body pivotally connected. The device has two gears, the first flexible gear for connecting the floating body to the second gear and the second gear for connecting the flexible gear to the generator. The flexible gear consists of pulleys and a flexible element, e.g. a rope or a steel cable and the second gear can be arranged in several suitable forms, e.g. rigid elements as a set of a gear and a rack positioned inside the lower supporting tube or a flexible element, e.g. a chain and a sprocket wheel set in the buoyancy element. The supporting construction is by ropes connected to the anchor weight that is made in a form of a sphere segment either directly or through the rolling elements placed in the spherical dent of the anchor base. The invention comprises the process for device deployment at the exploitation location which is particularly suitable due to stable transport with low draught.

A system that maintains the relative and/or absolute geographical positions of two or more buoyant devices floating in a body of water. A plurality of formation restoring tethers are disclosed which permit the unrestricted vertical movement of networked buoyant devices, while resisting increases in their lateral separations by providing restoring forces to oppose such separations. Tensioning mechanisms incorporated into the tethers generate the resistance to the lateral separations of two or more entities by transforming such separations into an increase in the potential energy stored within such tensioning mechanisms, the potential energy of which is released in the process of restoring the original separations and/or positions of the displaced buoyant devices.

A block type wave power generation apparatus of the present invention comprises: a floating unit for absorbing kinetic energy of waves and moored to the sea by a wire; a base unit for passing the wire extended from the floating unit therethrough and positioning the floating unit within a predetermined area of the sea; a power generation unit for transmitting kinetic energy of the floating unit from the wire passing through the base unit, and converting the kinetic energy into electrical energy.

A generator for capturing and converting wave energy into a more useful form is provided. The generator comprises: at least one energy capturing float (2) which is movable in response to wave motion; a reaction member (1) to be positioned below the energy capturing float; connecting lines (5a, 5b, 5c, 5d) for connecting the at least one energy capturing float to the reaction member and defining a spacing (D2) between the energy capturing float and the reaction member; energy convertors (6a, 6b, 6c, 6d) for converting relative movement between the reaction member and at least one respective energy capturing float to useful energy. The generator includes depth setting means such as adjustable mooring lines (3a, 3b, 3c, 3d) securing the reaction member to the sea bed SB for setting the depth (D1) of the reaction member in the sea. Both the float and the reaction member possess a positive buoyancy, allowing suitable tension to be applied to the mooring lines. The improved tension brought about by the net positive buoyancy has the surprising effect of improved stability in energetic sea conditions.

A computing apparatus that is integrated within a flotation module, the system obtaining the energy required to power its computing operations from waves that travel across the surface of a body of water on which the flotation module sets. Additionally, the self-powered computing apparatus employs novel designs to utilize its close proximity to the body of water and/or to strong ocean winds to significantly lower the cost and complexity of cooling their computing circuits.
