Toshiba announces a prototype of a Fuel Cell MP3 Player.

This Toshiba MP3 player is powered by a Methanol Fuel Cell. There is actually a Flash based MP3 player and a HDD based player. The fuel cell units have an output power of 100mW and 300mW respectively. Both prototype Toshiba Fuel Cell MP3 players include components related to the testing and are W35mm x L110mm x D20mm (flash memory) and W65mm x L125mm x D27mm (HDD) with the fuel cell units.
The HDD based Player has a 10ml fuel tank, which provides for a 60 hour play time. The Flash MP3 Player has a 3.5ml tank that holds for 35 hours. The two prototype players and their methanol cartridges will be exhibited at the CEATEC JAPAN 2005 which will be held at Makuhari Messe, Chiba Prefecture, from October 4 to 8, 2005.

I think the first time we reported about the Toshiba Fuel Cell development was already in 2003.
