Abstract: Wave energy conversion systems (WECS) with internal power take-off mechanisms using internal inertias as well as WECS using a submerged water head for driving a turbine at a steady rate. The WECS involving internal inertias is effected through relative oscillation between masses inside the hull of watercraft excited by wave motion and whereby the masses' oscillations are captured by actuators (e.g., hydraulic) that pressurize a fluid or generate electricity. Different relative oscillation mechanisms are disclosed herein. The WECS involving a submerged water head involve the use of asymmetric floats, arranged in a circular orientation for omni-directional wave energy capturing, that drive respective pistons that pressurize the water head and drive the turbine. Alternatively, the use of articulating raft/barges or floats coupled via a lever arm can be used instead of the asymmetric floats for pressurizing the water head.

Abstract: A potable water producing system for disposition at a salt water body and methods of producing potable water are provided. The system includes a wave energy conversion system (AWECS) and a portable filtration system. The AWECS forms a floating articulated barge having an onboard desalination system including reverse osmosis membranes. The filtration system is a sand filter residing on a damping plate submerged in the salt water body and filters the adjacent salt water for providing filtered salt water to the onboard desalination system. Wave action on the articulated barge provides energy to pump and pressurize the filtered salt water from the sand filter to the reverse osmosis membranes to produce potable water. The wave action on the articulated barge effects shaking of the reverse osmosis membranes, thereby rendering them self-cleaning. The potable water can be used for various applications, e.g., bottling, replenishing aquifers, ground and/or aquifer remediation, irrigation, etc.

Abstract: An articulating wave energy conversion system (AWECS) formed of a forward barge hingedly-coupled to a two-part aft barge configuration for reducing the attenuation of available wave energy along the length of the AWECS. The two-part aft barge includes a buoyant section that is either rigidly-connected, or unitized with, a lever-arm barge. The lever-arm barge includes a draft that is much smaller than the drafts of the forward barge and buoyant section. In addition, the lever-arm barge includes a large waterplane area that results in large hydrostatic forces as the waves pass. One or more intermediate barges may be hingedly-coupled between the forward barge and the aft barge. Pumps can be positioned across every hinge to convert the barge articulations into mechanical energy for driving the pumps based on wave motion for a variety of functions, such as water desalination, electrical energy generation, etc.

Abstract: An apparatus and method for generating electricity from ocean wave energy by using a floating device having a first portion that is movably coupled to a second portion. A hydraulic pump is coupled between these portions such that when the floating device is exposed to ocean wave energy, the hydraulic fluid within the pump is displaced. A flow rectifier is used to create a unidirectional hydraulic fluid flow that is dispensed through a rotary-vane pump which, in turn, is coupled to an electrical generator. Thus, as the rotary-vane pump is activated by the unidirectional hydraulic fluid flow, the rotary-vane pump turns the electrical generator for generating electricity. A plurality of hydraulic pumps and associated flow rectifiers, rotary-vane pumps and electrical generators can be coupled between the first and second portions.

Abstract: A constrained buoy experiencing vortex-induced, in-line and transverse angular motions and designed to absorb and attenuate the energies of streams, rivers and localized ocean currents is described. Referred to as a Finned-Spar-Buoy (FSB), the buoy design can be considered an exoskeleton, in that vertical fins are externally mounted on a vertical cylindrical float. The fins increase the drag coefficient by enhancing the wake losses. The FSB operates as a single unit or as a component of an array, depending on the application. The FSB can adjust to high-water events caused by tides, storm surges or spring-melting runoffs because the FSB can move axially along a center-staff which is attached to an anchor pole at a pivot point. The buoy-staff system is allowed to rotate in any angular direction from the vertical, still-water orientation of the center-staff. The FSB has a relatively small diameter-to-draft ratio, analytically qualifying the buoy as a slender-body.

Each buoy is arranged to be constrained, e.g., connected to an anchor, and comprising a body e.g., a cylindrical member having at least one outwardly projecting fin, that is configured to be resonant and impedance matched. The buoy and anchoring approach allows for self-tuning to the changes in the wave spectrum due to the tidal or storm surge induced changes in the water depth. The body of the floating buoy is not limited to circular cylinder, and could be square, hexagonal, triangular, etc. but must have at least one exterior mounted fin.
