摘要： 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.

摘要： A bi-directional pump system that can be configured for a plurality of operating modes. The bi-directional pump system includes a plurality of bi-directional pumps each having their own valving system that are connected to a common high pressure manifold, a low pressure manifold and a suction manifold. Via the respective valve systems, each pump can be configured into: (1) a single-acting pumping mode; (2) a double-acting pumping mode; (3) an inactive free motion mode; and (4) an inactive rigid mode. One exemplary application of the bi-directional pump system is on an articulated wave energy conversion system that consists of three floating barges: a front barge, a center barge and a rear barge where the front barge and center barge are hingedly connected as are the center barge and the rear barge. A first set of the bi-directional pumps span the first hinge connection and the second set of bi-directional pumps span the second hinge connection. The bi-directional pump system intakes sea water and, using wave energy, outputs a high pressure flow of sea water for water desalination and/or for driving electrical generators.

摘要： 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.

摘要： 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.
