ABSTRACT:
An ocean thermal gradient power plant utilizing the concept of converting the potential and/or kinetic energy developed as a low pressure, high specific volume steam to a hydraulic or kinetic working head in seawater. The plant comprises a hull having a pair of air-evacuated, partially submerged compartments therein. Each compartment contains a static hydraulic head and is interconnected with the other compartment above the level of the static hydraulic heads. One compartment contains a steam-lift pump which, in addition to the static head therein, creates a hydraulic working head therein. The water from the hydraulic working head drives a turbine and then exits the compartment to an intermediate depth. Steam from the steam-lift pump is drawn into the other compartment where it is condensed by a barometric condenser. The water in this compartment exits via a pipe extending from the level of the static hydraulic head to an intermediate depth. A Taylor compressor is located at the orifice of the pipe to remove any collected air from the system.
