Abstract
Traditional power generation with a turbine may be inefficient, costly or inconvenient. The improvement disclosed herein involves the use of two fluids. A pressurizing fluid is vaporized, pressurized and fed into a pressure cylinder holding a liquid working fluid. The pressurizing fluid forces the working fluid out of the pressure cylinder and through a liquid turbine to generate electricity or perform work. The working fluid is recycled from the turbine into another pressure cylinder for re-use. The pressurizing fluid is condensed and then also recycled back to the evaporator where it is vaporized and pressurized again. Use of a liquid rather than gas turbine makes for improved efficiency and lower cost. The use of a separate pressurizing fluid, which may be volatile, allows for convenient use where the temperature of the thermal source is limited.
