This Biolite Campstove is an amazing new product that transforms heat into electric energy. All you have to do is start a fire. No batteries or gas needed. Once the fire is started it is completely smokeless and will create 2 watts of electricity to charge led lamps, smartphones, headlamps, and more. The biolite captures waste heat and is transformed into usable electricity by a thermoelectric generator. It then powers a fan that sends electricity to a USB port. Mine is in the mail is yours?
