Patent ID: 7347049

Claim:
A system for generating energy, comprising: a first heat exchanger in thermal communication, fluid communication, or a combination of thermal and fluid communication with a first heat source, wherein the first heat exchanger heats a transfer fluid that comprises a working fluid and an associating composition, wherein the working fluid and the associating composition are capable of reversible associating with each other and wherein heating of the transfer fluid in the first heat exchanger generates a vapor comprising the working fluid; a first separator in thermal communication, fluid communication, or a combination of thermal and fluid communication with the first heat exchanger and downstream of the first heat exchanger; a first superheater in thermal communication, fluid communication, or a combination of thermal and fluid communication with the first separator and downstream of the first heat exchanger; a first energy conversion device in thermal communication, fluid communication, or a combination of thermal and fluid communication with the first superheater and downstream of first superheater, wherein the first energy conversion device comprises a moving surface that is contacted by the vapor generated in the first heat exchanger; an absorber downstream of the first energy conversion device and in thermal communication, fluid communication, or a combination of thermal and fluid communication with the energy conversion device, wherein the absorber is adapted to receive the vapor that has passed through the energy conversion device and to receive the associating composition that has passed through the heat exchanger; a first regenerator located upstream of the absorber and in thermal communication, fluid communication, or a combination of thermal and fluid communication with the absorber, wherein the regenerator is adapted to receive the transfer fluid from the absorber and allows the transfer fluid to return to the first heat exchanger; and a pump in thermal communication, fluid communication, or a combination of thermal and fluid conmunication with the first heat exchanger.
