Hitachi To Squeeze Fuel Cells Into PDA's
Japanese electronics giant Hitachi is teaming up with Tokai, a maker of disposable cigarette lighters, to produce commercial fuel cells for handheld computers in 2005, the companies said this week.
Several electronics companies are investigating fuel cells as an alternative to existing nickel cadmium batteries and lithium ion batteries, which will inevitably hit a barrier when portable devices become more power-hungry. Fuel cells, just one of the alternative techniques under investigation, could create a long-lasting and cheap power source in a small package.
Fuel cells generate electricity through a chemical reaction between oxygen and a fuel such as hydrogen or methanol. The cells continue to produce electricity as long there is fuel. Hitachi, Toshiba, NEC and NTT DoCoMo have all announced plans to sell methanol-powered devices.
Hitachi and Tokai said they have created a prototype cartridge about the size of an AA battery that holds 50 cubic centimeters of methanol at a 20 percent concentration. It could power a PDA for six to eight hours, the companies said. They are planning to raise the concentration to 30 percent by the time mass production begins, which would increase cell life.
Toshiba originally planned to produce a fuel cell in 2004, but delayed its plans by a year. In October, the company said it had created a product that is capable of providing approximately 20 hours of operation, using a 25 cubic centimeter fuel cartridge.

A USB toaster would be nice...
Mmm.... roadwarrior pop-tarts....
My PDA already gets >6 hours from a single battery, so these batteries don't sound that good.... as if you have to replace them.... or can you charge them?
NS
Now if they can give my 16 hours for my laptop that is a different story.
