Power Dense Bottoming Cycles for Microturbine Energy Recovery Navy SBIR FY2009.1 Sol No.: Navy SBIR FY2009.1 Topic No.: N091-072 Topic Title: Power Dense Bottoming Cycles for Microturbine Energy Recovery Proposal No.: N091-072-1225 Firm: Johnson Research & Development Co., Inc. 263 Decatur Street Atlanta, Georgia 30312 Contact: James Muller Phone: (404) 584-2475 Web Site: http://www.johnsonrd.com Abstract: The United States Navy (USN) is seeking innovative, power dense bottoming cycles for use in conjunction with microturbines. We propose a transformative and innovative, solid-state heat engine, the Johnson Thermoelectric Energy Converter (JTEC, US Patent 7,160,839) as an efficient power generator for advanced waste heat recovery for electricity generation. The JTEC technology was given a 2008 Breakthrough Award by Popular Mechanics and has also been featured in IEEE magazine "Spectrum". The engine is a direct heat to electric converter and can operate on a very wide range of heat source temperatures. The JTEC, which operates on the Carnot equivalent Ericsson cycle, can efficiently and directly convert thermal energy to electricity. The targeted power output for the bottoming cycle is 10kW at full load with a source temperature of 260�C. Preliminary models suggest that the JTEC can achieve the goals suggested in this solicitation. Benefits: This direct thermal to electric energy conversion system can provide a valuable resource for utilization of low to medium grade waste heat for energy intensive basic industries. The device can also generate power operating on combustible fuels, concentrated solar energy, geothermal, or any heat source. Additionally, the JTEC system can operate in reverse as a heat pump (electrically or thermally driven) or as a heat engine/heat pump combination to function as a thermal management system. Return
