The BioLite Camp Stove looks really neat. It is a portable, packable, high-effeciency, camp stove that generates electricity from the heat to also charge your gadgets:
Our stoves cook your meals with nothing but the twigs you collect on your journey, eliminating the need for heavy, expensive, polluting petroleum gas. Quick to light, fast to boil and easy to use. By converting heat from the fire into usable electricity, our stoves will recharge your phones, lights and other gadgets while you cook dinner. Unlike solar, BioLite CampStove is a true on-demand source.
Brilliant! Seriously, for anyone who enjoys the outdoors this seems like a no brainer.
