Photos: Fuel cells for music players

Toshiba's fuel cell for portable music players runs on methanol and adds as much as 60 hours of playing time to a flash memory or a hard disk drive music player. Toshiba said it expects the cells to be ready for sale by 2007.

If you want to crank more tunes out of your iPod, you might need a battery booster. This one, called Cellboost, connects with the 30-pin iPod and iPod Mini for an additional eight hours of playing time.
