Patent ID: 7614367

Claim:
A method of evaporating a fluid, comprising: providing a prime mover adapted to generate rotational kinetic energy and thermal energy; coupling a dynamometer to the prime mover so that rotational kinetic energy is transferred to the dynamometer; circulating a first fluid through the dynamometer to impart thermal energy to the fluid; circulating the first fluid through at least one heat exchanger adapted to transfer thermal energy of the prime mover to the fluid; circulating the fluid through at least a second heat exchanger; passing a second fluid through the at least second heat exchanger to transfer thermal energy from the first fluid to the second fluid thereby heating the second fluid; flashing the second fluid into its vapor and liquid phases; providing a holding tank adapted to contain the liquid and vapor phases of the second fluid; providing a fluid-to-air condenser in fluid communication with the tank for condensing a portion of the second fluid vapor by passing air across the condenser to transfer thermal energy from the vapor to the air; and providing an evaporation chamber in fluid communication with the tank for evaporating a portion of the second fluid liquid with the heated air.
