Abstract
Power is produced by a power plant using a salt-water solar pond comprising an upper wind-mixed layer, a halocline and a lower convective heat storage layer. The power plant includes a heat engine for utilizing heat present in the heat storage layer of the solar pond and a condenser, which preferably is cooled by liquid droplets. In accordance with a specific embodiment of the invention the power plant is positioned within the solar pond and a flash evaporator is used in the heat engine to produce steam which is supplied to a turbine connected to a generator, the heat depleted steam exiting from the turbine and being cooled by liquid droplets in a direct-contact condenser. The size of the droplets is selected such that the heat extracted in the condenser penetrates the majority of the liquid content of most of the droplets.
