Camp Stove Charges Your Phone, Cooks Your Goose : Discovery News
Discovery News on a USB-charging camp stove:
This stove has design, function and engineering packed into a small package. Roughly the size of a large plastic water bottle, it works by harvesting the heat energy from burning wood to create electricity to power a small fan; the fan increases the efficiency of the wood combustion generating even more heat and energy. The extra heat increases the boiling/cooking potential on top of the stove, while the extra electrical energy can be used to power an LED light or charge a USB device.
This is the kind of survival gear that I can get into.
