Portable Generator Charges Devices with Fire

Using the phenomenon of heat to electricity, two inventors have created a portable generator that uses heat from a campfire, stove or even candles to charge any device powered by a USB connection.

Originally developed for hikers and camper to keep their cameras charged, the device has the potential to bring power to people in developing countries where wireless technology has surpassed the availability of electricity. The technology behind the FlameStower is fairly simple – a blade extends over a fire, while the other end is cooled by a reservoir of water. The difference between the temperature of the two blades generates electricity and semiconductors amplify the voltage to a useful amount. It
