The thermophotovoltaic (TPV) generation of electrical power promises efficiencies that are exploitable for military and commercial applications. TPV offers a combination of unique characteristics as a power source for military Unmanned Undersea Vehicles. In civilian applications TPV technology offers the potential for lightweight, rugged, and reliable power systems that can be environmentally benign. These systems can use a variety of fuels and can be scaled up in size. TPV is truly a dual use technology in which the United States appears to have a technical lead. The focus of the current Quantum program is the maturation of the technology and the demonstration of a 10 kilowatt generator. Preliminary results of this project are presented.
