Abstract: Methods and systems for raising deep ocean water include pumping a quantity of fluid through at least one hose. At least one turbine is driven with the quantity of fluid pumped through at least one hose. At least one pump is driven with the at least one turbine. A second quantity of fluid is sucked into the at least one pump and driven through at least a second hose.

Abstract: An apparatus, system, and method for raising water is provided. The apparatus includes at least one container movable between at least a descended position and a ascended position within a body of water. A non-water-permeable membrane is positioned within the at least one container, wherein the membrane is movable within an interior compartment of the at least one container to separate the interior compartment into at least a first and a second portion. At least one vent structure is within a wall of the at least one container, wherein movement of the membrane controls a flow of water through the at least one vent structure and into at least one of the first and second portions.

Abstract: A system for raising water for OTEC and desalination is provided. The system includes at least one submerged platform positioned within a body of water, wherein the at least one submerged platform is buoyantly held up from a bottom surface of the body of water, and wherein the at least one submerged platform is held below a top surface of the body of water by at least one mooring attached to the bottom surface of the body of water. At least one cable is movably connected to the at least one submerged platform. At least one container is held by the at least one cable, wherein a quantity of water is emptied from the at least one container.
