Yup, the Ultimate Rocket Stove... it cooks, AND it can charge your cell phone at the same time!
This stove is among the 18 Semi-Finalists in the 2012 Buckminster Fuller Challenge.
BioLite is a biomass cookstove that converts waste heat into electricity, reduces smoke emissions by 95% for improved health. It also provides mobile phone and LED light charging capability.
Those are the HomeStove versions, above.
This is the CampStove version.
These stoves power all USB-chargeable devices including smartphones, GPS, and LED lights. They light quickly and easily, burn sticks, pine cones and other biomass. The CampStove folds for portability and weighs just over 2 pounds.
How it Works
Open wood fires are inefficient, wasting potential energy and creating toxic smoke due to incomplete combustion. Carefully designed stoves that use fans to blow air into the fire can dramatically improve combustion. However, such stoves require small amounts of electricity to power their fans and most people who cook on wood are without grid or battery access. BioLite stoves solve this problem by converting a fraction of the fire’s thermal energy into electricity to power our combustion improvement system. Excess electricity is made available to users for charging small electronic devices such as mobile phones, LED lights, GPS and many others.
