Abstract: For OTEC (Ocean Thermal Energy Conversion), rather than transfer huge quantities of cold water from deep in the ocean to the surface to provide a heat sink for a heat engine or for desalination, this invention provides a method of using small masses of low-boiling-point fluids to absorb heat in a heat exchanger near the ocean surface using the latent heat of evaporation and then depositing the latent heat of condensation in a deep ocean heat exchanger, using the cold seawater as a heat sink. The condensed liquid is pumped back to the ocean surface. The heat engine (turbine) and generator can be at the ocean surface, or it can be in deep ocean. By using a fluid that transfers heat by evaporation and condensation, much larger quantities of heat can be moved per kilogram of fluid than can be transferred by moving the same mass of seawater.
