The Dynario fuel cell charger from Toshiba will launch in Japan on Oct 29, bringing with it direct methane fuel cell injection that lets you charge two cellphones simultaneously.

The first 3,000 run will cost 29800 Yen ($328), and you get five cartridges for 3150 Yen ($34), which makes it cost ineffective if you're talking about practical charging.
