Abstract: An improved Ocean Thermal Energy Conversion system (called OTEC) is presented herein by the addition of a closed heat transfer loop. In conventional OTEC, warm surface waters are used to vaporize a working fluid for use in a turbine, and cold waters are then brought up from deep water, typically more than 1000 meters, to condense the working fluid. In simple terms conventional OTEC brings the cooling potential up to the warm surface. The disclosed OTEC system brings the heat down to the deep cold waters by using a separate heat transfer fluid loop. We refer to this as Enhanced OTEC or E-OTEC. A key feature of the process is descending to the depths as a dense fluid and returning to the surface as a much lower density fluid, thereby gaining a gravitational boost in pressure and temperature. This leads to several technological, performance, and economic advantages over prior art.

Abstract: Systems and methods are presented for deploying and using a floating platform using articulated spar legs used as a type of hull, each of the spar legs attached to the floating platform by an articulated connection. Each of the articulated spar legs being moveable from a horizontal to a vertical position, horizontal for transport and vertical for deployment of the floating platform. The articulated spar legs serve to support the floating position of the floating platform. The articulated spar legs are moved from horizontal to vertical position by controlling ballast imposed upon or within spar legs. Each of the articulated spar legs are moveable from a vertical to a horizontal position with a ballast changing method. Systems and methods are presented for extracting natural renewable energy from the environment surrounding the floating platform with energy capture devices modularly affixed to the platform and energy capture devices incorporated into the articulated spar legs.
