  • THERMAL GRADIENT HYDROELECTRIC POWER SYSTEM AND METHOD
    Publication number: 20160363114
    Abstract: A thermal gradient hydroelectric power system and method is disclosed herein. Specifically, the method can comprise cycling through a submersed evaporator warm from a natural warm water source, said warm water source having a first temperature. The method also can comprise evaporating a working fluid using said evaporator, and routing the working fluid from the evaporator through a vapor line to a condenser above said evaporator. Finally, the method can also comprise cycling through a condenser cold water from a natural cold water source, the cold water source having a second temperature, and condensing the working fluid, the working fluid having a boiling point between said first temperature and said second temperature.
