Development of a 2·2 Watts Thermoelectric Power Source for A.I.R. Community Receiver

Abstract

One kerosene oil-fuelled thermoelectric generator of maximum power capacity of 2·2 W. d.c. has been designed and constructed with ZnSb and constantan elements for powering A.I.R. community receiver requiring about 2·0 W. d.c. for maximum useful output from the receiver. The receiver generally operates from a 9 V. dry battery pack, which is costly and having limited self life and irregular supply. Whereas, the generator works on cheap fuel readily available even in remote villages, its running cost is practically nil with kerosene lamp supplying normal light at night and is about 10 np/hour with wick-stove and is having very long life. Some design aspects and the cost estimation of the generator are also presented in the paper.
