Abstract
Power is generated from a body of hot brine by injecting a liquid operating fluid, such as butane or Freon, into the brine at a depth where the hydrostatic pressure of the brine is approximately equal to the vapor pressure of the operating fluid at a temperature of the brine for producing a bubble regime in a vertically oriented lift tube whose lower end is immersed in the brine whereby working fluid is raised in the lift tube as the bubbles rise therein. The gaseous operating fluid is separated from the liquid working fluid which is returned to the body of brine, and the gaseous operating fluid is condensed in a condenser and returned in a liquid state for injection into the hot brine at the inlet of the lift tube. The working fluid that is raised in the lift tube is passed through an hydraulic turbine.
