Title: Combustion heat powered portable electronic device

Abstract: A combustion heat powered portable electronic device. At least onethermoelectric module is sandwiched between a hot block heated by acombustion heat source and a cold-side heat sink and provides electricpower to a portable electronic device from the temperature difference. Anelectric circuit provides power for purposes of operating the portableelectronic device either directly or indirectly by charging a rechargeablebattery which in turn provides power to the electronic device. In apreferred embodiment the combustion heat source is a catalytic combustionunit. The hot block and/or cold side heat sink can be integrated into asingle unit with the thermoelectric module. In a preferred embodiment thecold side heat sink is cooled by fins cooled by air driven by a forced airfan powered by the thermoelectric module.
