Portable Thermoelectric Generator.
Abstract
Progress is reported on a 150-w portable thermoelectric generator, employing a leaded gasoline burner as the heat source, and weighing no more than 30 lb, including fuel for 4-hr operation. A process was developed for forming rectangular hexahedral semiconductor thermoelectric elements from granular starting material, by hot pressing in graphite dies. The thermoelectric materials selected are commercially available PbTe with 0.055% PbI2 (n elements) and PbSnTe (p elements). The gasoline burner and an aspiration system for the intake of both combustion and cooling air have been intensively analyzed. Critical nozzle experiments are under construction. The design of the energy conversion stage is substantially complete. (Modified author abstract)
