According to Engadget, the new docking station, which works with Samsung's Q35 ultraportable laptop contains a 1200-watt-hour fuel cell.
The dock can power a laptop eight hours a day, five days a week for a month. Apparently the boffins are working on a miniature version which can power a laptop for more than 15 hours "on a coffee cup's worth of fuel". Although it is not clear how much fuel there is in a cup of coffee.
The dock is powered by a Direct Methanol Fuel Cell with a maximum output of 20 watts. This technology is jolly good at producing small amounts of power over a long periods at low temperatures, making them well suited to mobile devices.
Samsung says that the cell's 650Wh/L energy density is four times that of its competitors. Apparently the dock will hit the shops at the end of next year. More here. ยต
