BBC News has a piece on fuel cells as laptop batteries, and what their adoption could mean for laptop usage." From the article: "At the Cebit technology fair in Hanover, Taiwanese hi-tech firm Antig said its fuel cells should be on the shelves of computer shops by early 2007. The first versions of the methanol-using units should keep a laptop going for up to nine hours. Fuel cell technology got a boost recently when international air flight regulators changed rules that banned passengers from carrying flammable methanol onto aircraft."
