ABSTRACT:
A power generating system is powered by a circulating working fluid that is heated by heat of condensation deposited in a concentrated brine solution. A condenser transfers heat from working fluid vapor exhaust from the turbine to cooling water to form a condensed working fluid and heat the cooling water to a first vapor pressure. A heat transfer chamber has a concentrated brine solution in vapor communication with the cooling water so that vapor from the cooling water at the first vapor pressure will condense on the brine solution for diluting and heating the brine solution. For efficient heat and vapor transfer, the cooling water and the brine solution are caused to flow along opposed surfaces. A boiler is placed in heat transfer communication with the brine solution for receiving heat from the brine solution and heating the condensed working fluid to a vapor for input to the turbine.
