Wood-burning stoves aren't known for being particularly efficient, and their smoke not only contains high carbon emissions but causes health risks to those who inhale it. A portable design from BioLite aims to tackle this problem and turn the stove into a cell phone charger in the process. The stove converts heat energy into electricity, powering a small fan to improve the wood's combustion. Beyond this, one to two watts are available to charge a cell phone or LED light via a USB port.
