Abstract:

A buoy for use in reducing the amplitude of waves in water and a system making use of plural buoys to create a floating breakwater. 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.

US Classification:

114 26

Abstract:

A wave-powered device having enhanced motion. The device including first, second, and third barges, with the second barge having a first reservoir and a second reservoir. The first and second reservoirs being coupled by a first passageway to permit a first fluid to selectively and passively move between the first and second reservoirs in a predetermined manner to increase the pitching moment of the second barge while the second barge pitches while floating over waves. A first coupling mechanism is coupled between the first and second barges to enable the first and second barges to move relative to one another, and a second coupling mechanism is coupled between the second and third barges to enable the second and third barges to move relative to one another.

Abstract:

A filter-anchor for placement on a sea floor is provided. It includes a filter housing for filtering sea water prior to entry into a water desalinization system. The filter housing has an exterior, an interior chamber, at least one inlet for providing the sea water to the interior chamber, and at least one outlet for enabling filtered water to be pumped from the interior chamber. A sand filter is disposed in the filter housing. The filter housing has at least one water conduction outlet conduit for filtered water to be pumped to the desalinization system. A wave energy conversion system utilizing the filter anchor is also provided to effect the pumping of the filtered water to the desalinization system. A method of anchoring a wave energy conversion system and providing filtered water to a desalinization system is also provided.

Inventors:

Michael E. McCormick - Annapolis MD

International Classification:

F03B 1312

US Classification:

60398

Abstract:

A counter-rotating turbine for converting energy from waves. A turbine is positioned in a pneumatic-type wave energy converter and converts the energy of alternating air flow above the internal water surface into mechanical energy. The turbine has counter-rotating runners and guide vanes located both upstream and downstream, and the alternating air flow in the energy converter excites the turbine runners after being turned by the guide vanes.

International Classification:

F03B 13/22
F03B 13/14

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.

International Classification:

F03B 13/20
F03G 7/08

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.
