Nokia's fuel cell Bluetooth headset

Probably because it's sorta ridiculous to have a wireless Bluetooth headset that has less talk time than the cellphone it's paired with (you'd be surprised how often this is the case), Nokia has been testing a fuel cell-powered version of their HS-3W Bluetooth headset that can get about ten hours of chat time on single methanol cartridge, which should be long enough to outlast all but the hardiest of cellphone batteries.
