Korea’s Samsung Electronics has developed a docking station equipped with a fuel cell capable of powering a laptop for a month.

Designed for Samsung’s Q35 ultraportable laptop, the docking station contains a 1200-watt-hour fuel cell, reports Engadget. The dock is capable of powering a laptop eight hours a day, five days a week for a month. A minature version is under development which can power a laptop for more than 15 hours on a coffee cup’s worth of fuel.

The dock uses a Direct Methanol Fuel Cell with a maximum output of 20 watts. DMFCs are best suited to producing small amounts of power over a long periods at low temperatures, making them well suited to mobile devices. Samsung claims the cell’s 650Wh/L energy density is roughly four times that of its competitors.

Samsung plans to launch the dock at the end of 2007.
