Toshiba has demonstrated two new dimunitively sized methanol fuel cells that can power a flash based device for 35 hours and a (larger) battery that will power HD based MP3 players for 60 hours. On track to be included in portable audio players by 2007, these Toshiba batteries can fully charge in one hour.

The Philoneist Says: With wireless charging of mobile devices
also coming in the near future, hopefully Toshiba will be able to
integrate some of this innovation into their fuel cell batteries before
they saturate the market.
