During a second stroke of the WEC subsystem: the float moves in a second direction; seawater is supplied from a seawater intake to the first variable volume chamber; and seawater is supplied from the FSD to the RO cell.

In one aspect, a system for generating electricity based on water flow is disclosed. The system comprises a first pipe fitting, a turbine, and a second pipe fitting. The first pipe fitting couples to a pipe that supplies a fluid to a building. The turbine is in fluid communication with the first pipe fitting and rotates in response to a kinetic energy of the fluid supplied by the pipe flowing through the turbine, generates electricity in response to rotation of the turbine, and reduces a pressure of the fluid from a first pressure to a second pressure. The second pipe fitting couples the turbine to an input pipe of the building. The turbine further comprises a conversion circuit that conditions the generated electricity for consumption by the building and conveys the generated electricity to the building via one or more conductors.

An electric water desalination assembly for desalinating water without burning fossil fuels includes an evaporator and a renewable electrical power generation system. The renewable electrical power generation system is electrically coupled to the evaporator for providing power to the evaporator. The evaporator is fluidly coupled to a source of salt water for boiling the salt water into desalinated steam. Additionally, the evaporator is fluidly coupled to the water desalination system for processing the desalinated steam into freshwater. Additionally, the water desalinating system is fluidly coupled to a freshwater distribution system. In this way the freshwater distribution system receives freshwater from the water desalination system.

The present invention discloses a pressure converter system for sustainably forcing saline water through a semi-permeable membrane, comprising a hydraulic oil pump, a hydraulic oil cylinder comprising pressurized oil generated from the hydraulic oil pump, a sustainable energy source for powering the hydraulic oil pump, a saline water cylinder containing saline water, wherein the hydraulic oil cylinder and the saline water cylinder are connected using a piston and an electrical circuit for determining a direction of movement of the piston. This system may be developed to a stand-alone desalination facility comprising a ducted windmill that can harvest energy from a wide range of wind speeds, especially very low wind speeds. Because of the above, the present invention successfully converts mechanical energy to high pressure that is required to produce fresh water from saline water.

The APPARATUSES, METHODS AND SYSTEMS FOR HARNESSING THE ENERGY OF FLUID FLOW TO GENERATE ELECTRICITY OR PUMP FLUID include a device which, when placed in fluid-flow, harnesses the kinetic energy of the flow to generate electricity or to perform useful mechanical work such as pumping. For example, the undulating mechanical action of traveling waves along flexible fins may be harnessed by summing the varying speeds and torques along the fins into a unified circulatory system for power take-off or fluid extraction. The device may include two fins, a chassis, and bellows/pistons/rotary vanes and the like which are connected via a circulatory system of tubes or conduits.

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.
