Here's how it works: The fuel cell is placed under the hot coals of a stove fire, while the "handle" of the device juts out. A cord attached to this end can be plugged into a cell phone, while the fuel cell uses oxygen from the air to convert the burning carbon into electricity. The device weighs just half a pound, and includes an LED light that can provide up to 30 hours of light on a full charge.
The device was developed by Point Source Power, an Alameda, CA-based company, which offers a few different stove-powered charging products.
The fuel cell used in the VOTO is a metal-supported solid oxide fuel cell (M-SOFC) made of low-cost stainless steel and thin layers of active materials.
