We plan to build and test a thermoelectric battery charger that is integral with a 1-qt saucepan, with the thermoelectric array firmly affixed to the bottom of the pan, yet protected from the fire, and the em-silent battery charger circuitry within the handle. Saucepan, generator, circuitry, and cable together will weigh less than 5 lb. When placed atop a cooking fire, and when containing water, it will provide a constant one-ampere current, suitable for charging the bb-586/u 13.2-volt sealed nickel cadmium battery used in field communication sets, disconnecting automatically when the temperaturecorrected battery voltage indicates a full charge.
