Abstract :
Thermoelectric generators use the Seebeck effect to produce electrical power from a temperature difference caused by heat energy flow. In this paper the principle of using thermoelectrically converted heat energy for powering portable electronic equipment or charging its battery has been investigated for a lap-top computer. The thermoelectric battery charger developed, consists of a thermoelectric converter system, powered from butane gas, and a DC-to-DC boost up converter. Both the sub-assemblies are designed using computer models and constructed. The unit produces an output power of 5 watts which doubles the life of the lap-top computer´s internal batteries
