Echogen Power Systems (formerly dba Rexorce Thermionics, Inc.) is structured around an innovative waste heat recovery system. Echogen's technology transforms waste heat directly into clean, emission-free electricity. Echogen's Thermafficient® energy recovery systems --- inspired by a patented absorption heat pump developed by NASA's Jet Propulsion Laboratory -- utilize supercritical carbon dioxide (ScCO2) and a range of combination fluids to create a power generating cycle in applications as broad as bottom cycling in gas turbines, industrial waste heat recovery, solar thermal, geothermal, and hybrid alternatives to the internal combustion engine. Additional patent-pending technologies developed by Echogen enable the system to operate using a broader range of heat sources to satisfy a wider range of applications that competing technologies cannot address. A former subsidiary of Cognitek Management Systems Inc, Echogen Power Systems, LLC also offers heat recovery engines for various power outputs serving companies that generate heat as a byproduct of their processes. In July 2015 Echogen did a deal with Doosan Heavy Industries & Construction Co., Ltd., a subsidiary of Doosan Group, is one of the largest Korean heavy industrial companies.
