Fuel Cells for Laptops: The Wait is (Almost) Over


We've been hearing about fuel cells for laptops for some time now (they keep appearing at trade shows and on websites) but haven't actually seen one on the shelf. Unfortunately, the wait continues, though claims of smaller, more powerful versions keep us chomping at the bit to get our hands on one. The latest incarnation, from UltraCell, claims two days of laptop life, which is quite an improvement over the 20 hours we saw in the most recent prototype. Sadly, this UltraCell model is just a prototype, and the military gets the first shot at them once production-ready. UltraCell hopes to have a commercial version available at the end of this year; we're ready when they are! ::UltraCell via ::Engadget
