ABSTRACT:
A power system is provided that uses the latent heat of fusion of water to raise the potential energy of a working fluid to a level that upon release generates power, preferably electrical power. The system is self-sustaining except for the energy that is supplied in water entering the system. The inlet water can be at any temperature within its liquid range under atmospheric or super atmospheric pressure, can advantageously contain the sensible waste heat typical of effluent from fossil fuel or nuclear power plants, can be relatively pure or be contaminated as with sewage or be the medium of a colloidal suspension, or consist of marine or other saline waters. In every case, purification of the water by freezing, for example, desalination, is accomplished without additional power consumption.
A selected working fluid that boils at a temperature substantially below the freezing point of water is brought in the liquid state into contact with the water or other aqueous medium, causing the water to freeze and the working fluid to vaporize under pressure; the produced ice is removed; a portion of the so-produced ice is admixed with a eutectic forming salt to create a cooling medium at a temperature below the condensation temperature of the cooling fluid; the working-fluid vapors are preferably superheated by inlet aqueous medium and are released from autogenic elevated pressure to drive a turbine. Working fluid vapors are condensed by said cooling medium and returned by pumping into contact with inlet aqueous medium.
