NOVELTY - The plant has a main portion comprising a heat exchanger (3) near a surface portion (1), a condenser (9) at depth, multiple pressure sensors to monitor depth of the surface portion, an electricity generating turbine (5) and an optional cold working vapor condensation compressor. Multiple pumps (10) are provided in the main portion to control amount of sea water in a ballast tank in the surface portion, so that depth of the surface portion is maintained continuously. An anchor cable is connected to a bottom of an ocean floor so as to secure the whole plant to the bottom of the ocean floor.    USE - Ocean thermal energy conversion (OTEC) electricity generating plant for supplying electricity to nearby community, and converting sea water to alternate form of energy.    ADVANTAGE - The plant uses induced pressure to promote condensation and uses semi-submerged anchor cable anchored to the ocean floor to secure the OTEC plant, thus achieving stability of the plant. The plant uses the working fluid, which is transferred from a warm region to a cold region and back to the warm region inside a steel tube, thus avoiding the need to move cold or warm seawater. The plant uses non-corrosive and high purity working fluid to avoid biological fouling of a heat exchanger tube while performing biological activity at depth of 500 meters. The warm water heat exchanger is placed deeper than the depth of marine life, so that the OTEC plant is protected from bad weather. The OTEC plant functions near peak capacity while performing biological activities without severe impedance of heat transfer of working fluid on the seawater. The plant is provided with a barrier to prevent ocean creature from direct contact with the OTEC heat exchanger. The heat exchanger interacts with seawater to cause strong convective seawater flow, so that the heat exchanger interacts effectively with large amount of seawater and allows the OTEC plant to operate at higher power capacity. The plant stores more energy while operating the plant with slow water circulation to extract thermal energy. The plant allows reuse of OTEC plant expelled wasted heat by natural circulating effect, thus reducing the cost of electricity generation.
