NOVELTY - The system has a cable downwardly moved into water and provided with a weighted section at a cable bottom. A rotary bladed unit spins along direction regardless of up/downward motion via facing adjacent blades on either side of a rotating circle along opposite directions. A wave powered piston pump acts as a syringe to drive fluid e.g. brine. The unit and the pump are incorporated into a submerged platform or sea bottom at which system hardware is safe from storm, wave and shipping. A buoyant element at a sea surface is contained within a frame, which allows the element to rotate axially.    USE - Wave powered system for raising sea water to create useful work or electricity from wave energy for driving an ocean thermal energy conversion (OTEC) atomizer system.    ADVANTAGE - The system enables insulation for an inside layer of a diving container, so that a water layer permanently held in the inside layer is easily cooled in deep water even during warming to provide cost effective insulation, thus preventing corrosion of the system by a heat exchange unit using plastic bags and reducing bio fouling on heat exchangers by allowing aluminum to be used, while reducing weight of the container by using less dense outer fluid and allowing water or electricity to pass to and from a ship even in the storm. The system allows a closed cycle OTEC unit to utilize the pump to move working fluid from a condenser to an evaporator such that brine or waste cold water held in the container can drive the cable and a fly wheel to drive the pump, so that the waste brine from a desalination plant is transported via a hose from a sea shore, solar fresnel lenses boil the water to make steam to drive the pump and additional brine is created, thus increasing utilization of waste heat to warm a surface water slightly above predetermined level, and hence improving efficiency of the OTEC atomizer system. The system allows a wave pump piston housing to be held closer to the sea surface and the pump to draw the fluid held in hoses that form up stroke from the submerged platform so as to provide sufficient grounding for the pump to work properly, while reducing cost of the cable for the pump. The system allows a large number of pumps and gravity units to be held on a rigid structure that is built from the sea bottom to include pipes with the pump inside so as to improve durability of the system. The system utilizes the waste cold water to be valuable for efficient pollution minimization and the pipes within the container to provide an economically efficient rigid extractor to create a precise flow rate and minimize a gain in temperature of the cold water through friction. The cable has length that can be adjusted to compensate a change in wave weight so as to suit for deep water applications in which long rigid poles are vulnerable to pump the water through the hoses from lower regions to the surface, while improving feasibility of the system.
