A power generating system for sailboats and sailing vessels employing the vacuum provided by a Venturi generator while the boat or vessel is in motion. Placement of a turbine for recovering the energy of air moving from the atmosphere to the throat of the Venturi generator in a duct leading from above deck to the Venturi generator. A variety of methods for generating the required vacuum while avoiding fouling of moving parts and clogging by debris in the water.

Methods, systems, and devices are disclosed for wave power generation. In one aspect, a wave power generator device includes a stator assembly and a rotor assembly encased within a tube frame. The stator assembly includes an array of inductor coils in a fixed position within a cavity of the tube frame and a plurality of bearings coupled to the tube frame. The rotor assembly includes a turbine rotor having a central hub and peripheral blades coupled to a high inertia annular flywheel that is moveably engaged with the bearings of the stator assembly, and an array of magnets arranged to be evenly spaced and of alternating axial polarity from one another extending from the annular flywheel into the cavity between the array of inductor coils, such that electric currents are produced based on magnetic field interaction of the magnets with the inductor coils during the rotation of the annular flywheel.

Wave energy conversion (WEC) systems and methods for harvesting wave energy by use of the systems are described. WEC systems incorporate a plurality of submerged oscillating water columns (SOWC) that encourage oscillating water motion within each submerged column to mimic the motion of waves passing the SOWC system. A WEC system includes multiple SOWC connected to one another via air pockets within each submerged column. Each SOWC includes a float connected to a power take-off. The oscillations of the floats are converted to useful energy by the power take-off of the system.

Disclosed is a novel device that converts some of the power in ocean waves into electrical power or other means of performing useful work. One or more tubes are arranged so that when the device is in position in a body of water, the tubes are oriented vertically with one end positioned proximate to and/or above the surface of the body of water on which the device floats, and with the other end positioned below the surface of that body of water. In some embodiments, through a differential restriction on the flow of air in and out of an upper end of the tube, the average height of the water inside the tube is different from the average height of the water outside the tube. In some embodiments, a hollow void inside a flotation structure of the embodiment is filled with water to contribute significant mass to the embodiment and increase the momentum associated with its vertical oscillations. Additional elements of the present disclosure include features that protect the device from damage during periods of large waves, and facilitate the powering and cooling of computers and/or other electronic equipment operated therein.

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 system and method for producing compressed air from ocean waves. The system includes an enclosing frame having a base anchored to an ocean floor with two or more columns extending upward from the base to above the ocean surface and a platform at an upper end of the columns. A float is located in the frame between the columns so that the float is confined to go up and down. The float is placed on the ocean surface within the frame and goes up and down with the ocean waves. One or more pumps are located on the platform with the hammer head that can be raised and lowered to produce compressed air with the pumps. The hammer head is connected to the float with two or more elongated shafts so that the hammer head is raised and lowered by the ocean waves and produces compressed air.
