exclusively to the US Army (unless you can make due with one lowly watt). Panasonic says we have another four years to wait, planning for a 2012 releasing of device powerful enough to run a notebook yet small enough to fit inside a battery compartment. The company estimates up to 5 hours of power could be had from 50cc of "highly concentrated" methanol, and of course you'd always be just a squirt away from a full charge -- the same sort of promises we've heard again and again about this tech. Four years may seem like a long way off, but it's surely more realistic than the release dates we've seen on some earlier prototypes.
Update: A few 200cc, 20-hour prototypes displayed after the break.
