I'm almost too scared to tell you that the BioLite camping stove can burn anything. I don't want to know what you'd shove in there. Still, the leftover heat can be used to power your gadgets - that's good, right?
Shame it's not on sale yet, and if it does it'll be for developing countries only. It's the ideal stove for you and I to take away on our camping trips though - separately, I mean. That's not an invitation to sit by the campfire and sing songs as I knit.
Powered by a thermoelectric generator, the fan separates wood gas from the sticks and other pieces of wood you've lit, blending it with air so it should roar nicely. The generator stores any excess power generated while the fire is burning, so it can be connected (via USB) to your gadgets. Apparently it takes just four minutes to boil one litre of water - sure beats singing kumbaya for the 10th time as you're waiting for your cup of tea. [BioLite via OhGizmo via Wired]
