At Japan's CEATEC show, Toshiba and KDDI are demonstrating a modified Toshiba T002 phone that's powered by a direct-methanol fuel cell (DMFC) and Li-Ion battery. More advanced than previous prototypes, it runs for 320 hours on a squirt of methanol. DMFCs produce electricity from a reaction of methanol, water, and air—the only by-products are a small amount of water vapor and carbon dioxide. Japanese wireless carrier, KDDI, has combined the fuel cell with a Lithium Ion battery. (source: gizmodo.com)
