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-anchor system. The AWECS forms a floating articulated barge having a desalination system including a reverse osmosis membrane. The filtration-anchor system is submerged in the salt water body and includes a sand filter to filter the adjacent salt water for providing the filtered salt water to the desalination system on the articulated barge. Wave action on the articulated barge provides energy to pump the filtered salt water from the sand filter to the reverse osmosis member to produce potable water. The wave action on the articulated barge effects the shaking of the reverse osmosis filter, thereby rendering it self-cleaning. The potable water can be used for various applications, e.g., bottling, replenishing aquifers, ground and/or aquifer remediation, irrigation, etc.

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.
