Toshiba has unveiled a prototype fuel cell it hopes will become the power source for laptops in the future... The fuel cell breaks down methanol to generate power and, Toshiba claims, will provide enough juice to run a laptop for about five hours....Toshiba hopes to put the fuel cell on sale in early 2004...


.....Mr Akashi said the commercial versions will be slightly larger than existing lithium-ion batteries and use the same power interfaces so they should work with older laptops....

...Existing laptops should get about five hours of work time out of a fuel cell, said Mr Akashi. Laptops that use Intel's Centrino chipset that minimise power use should get up to 20% more time...

...Future versions of the fuel cell should be able to power a laptop for about 10 hours. Toshiba is also working on fuel cells for PDAs and cellphones.....

LOL!
