2-Amp TPV cogenerator using forced-air cooled gallium antimonide cells Available to Purchase

We will describe a wall mounted TPV cogenerator for use as a battery trickle charger and 5,000 BTU/hr room heater on boats, in remote cabins, and in recreational vehicles. Propane is used to heat a proprietary matched emitter, and the emitter is surrounded by a photovoltaic conversion array consisting of 48 GaSb cells connected in series. Warm air generated by forced-air cooling of the array cooling fins is used for room heating, while combustion exhaust gases are vented to the outside. The generator will be demonstrated at the conference. Beta site test units are presently being assembled, and production units are expected to be available this fall.
