Abstract
A method of utilizing the thermal energy of environmental fluids to produce mechanical work or electricity by an energy conversion system wherein: the source fluid gives heat to the working fluid of a prime mover through a first heat exchange means and is cooled thereby; the cooled source fluid effluent from the said first heat exchange means is further cooled by passing it through a further cooling system which includes either a turbine or an expansion device or both; the further cooled source fluid is employed to cool the expanded working fluid of the prime mover, and the source fluid effluent from the energy conversion system may be used for other cooling and refrigeration processes, such as desalination of seawater, cooling of superconductors, etc.
