Say what you will about the Playstation 3, here’s one area in which Sony plans to be a market leader: Fuel cells. The company will roll up to the Fuel Cell Expo in Tokyo this weekend with a charger (pictured above), two mini chargers and a wireless speaker, all powered by a methenol and lithium-ion hybrid. The devices can switch between either power source or use both when more juice is needed. Expect a month’s supply of power on the big charger and a week’s worth on the portable version. In addition to the fuel cell technology, Sony will also show off a sugar-powered battery, using any sweet soft drink as the energy source. These sound pretty funky — I wonder how long it’ll take to get them to market. [Kaden Watch via Dvice]
