Abstract: A hinge system and method for an Articulated Wave Energy Conversion System (AWECS) that provides for hinge and piston pump displacements due to multi-axis forces in allowing adjacent barges of the AWECS to pivot with respect to one another due to wave motion. The hinge system uses a plurality of parallel hinges, and axle segments, coupled between adjacent barges wherein the hinges are coupled to upright trusses positioned transversely along facing edges of each barge. Hinge bracing includes lower V-shaped struts that act as lower stops when the barges pitch up and also include upper struts that act as upper stops when the barges pitch down. The pumps are positioned in parallel. The pumps have special couplings such as ball joint couplings that permit motions other than longitudinal pump/ram motions due to multi-axis forces generated by the wave motion and thus provide omni-directional stress relief to the pumps.

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: 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.
