A hydraulic wave energy converter, for converting wave energy into high-pressure water energy, includes a rectangular upper floating body (1) floating on water surface, a cylindrical housing-shaped lower floating body (2) under water, a first cable (3), a second cable (4), a hanging rod (5), a ball hinged hook (6), a sea floor anchor pile (7), and other mooring facilities. A plurality of water hydraulic cylinders (8) are vertically fixed at two wider sides of the upper floating body (1) and are reliably connected with the lower floating body (2) through piston heads (27), piston rods (28) and piston rod seats (29). The hydraulic wave energy converter can convert the vertical component and the horizontal component of the wave motion into high-pressure water energy for impacting a hydraulic generator set to generate power, and is lower in cost, simple in maintenance and high in wave energy conversion efficiency.

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 energy converter includes a surface float including a non-axisymmetric profile, a reaction plate configured to be submerged below a water surface, and more than one flexible tether, each mechanically coupled to both the surface float and the reaction plate, the reaction plate having a moment of inertia in pitch and roll greater than a moment of inertia in pitch and roll of the surface float.

A floating eagle type wave power generating device includes an eagle-head-shaped wave absorption floating body, a ship-shaped underwater appendage and a door-shaped support arm. The eagle-head-shaped wave absorption floating body is fixedly connected with an upper end of the door-shaped support arm. A lower end of the door-shaped support arm is connected with first hinges. The first hinges are fixedly connected with the ship-shaped underwater appendage through a base. The door-shaped support arm, together with the eagle-head-shaped wave absorption floating body, can rotate around the first hinges. L-shaped underwater appendages, mounted at two ends of the ship-shaped underwater appendage, are connected with the ship-shaped underwater appendage through second hinges and can rotate around the second hinges. A main floating body is arranged above the ship-shaped underwater appendage and below the eagle-head-shaped wave absorption floating body. The ship-shaped underwater appendage is provided with buoyancy compartments and equipment compartments.

A device for generating electrical energy from mechanical motion includes a surface float and at least one force modifier disposed at least partially within the interior of the surface float, the force modifier to receive an input force at a pumping cylinder and apply a modified force to a generator through a driving cylinder. The pumping cylinder or the driving cylinder is a tandem cylinder.

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.

A water-drawing structure for an ocean energy generator includes a sea-water collection tank with multiple locating posts at its bottom. An intake conduit includes a check valve connected to the tank, and a water-drawing assembly connected to the intake conduit. A floating element on the water surface is connected to a linkage system comprising a main linkage, a piston rod and a floating element linkage. The main linkage pivots on a pillar at one end and is connected to the floating element linkage at the other end. The piston rod is connected between the main linkage and the water-drawing assembly. A counterweight is connected to the main linkage where it connects to the floating element linkage. One pillar has two positioning feet between which the main linkage passes. As waves cause the floating element, the linkage system drives the water-drawing assembly to pump seawater efficiently for power generation.
