Biolite’s Brilliant Camp Stove Converts Waste Heat Into Electricity for USB Gadgets

This pint-sized invention converts the fire's heat into usable electricity, so now you can recharge your phones while you roast your marshmallows over the fire.

Biolite's new device helps keep a hot camp fire sustainable. Their green Camp Stove works like a traditional campfire using twigs and a flame to help campers avoid using expensive and polluting petroleum gas to give a cleaner fire and reduce the amount of CO2 regular camping stoves produce.

The device is also a safer option to an open fire, a more dangerous method which Biolite say causes 2 million premature deaths annually worldwide.
