A high efficiency thermal energy conversion working fluid based in large part on hybrid ionic liquid solutions and its application within thermal energy conversion devices is disclosed. Using the preferred ionic liquid and carbon dioxide gas with partially miscible absorber fluids, including the preferred ionic liquids as the working fluid in the system. The thermal conversion device transforms thermal energy, including low quality, into heating, cooling, mechanical energy, or electricity. Strategic use of heat exchangers, preferably microchannel heat exchangers comprised of nanoscale powders can further increase the efficiency and performance of the system. |
