There isn't much out there that the BioLite camping stove can't burn. What makes this compact stove even better is that it stores excess energy produced while it's cooking your meals and heating your beverages, which can be used to charge your gadgets.

The BioLite camping stove is powered by a thermoelectric generator that will bring one liter of water to boil in just four minutes. It isn't currently available for sale but I'm sure an ingenious distributor will pick it up soon.
