I am not sure if this is a good idea or not but Toshiba announced at CEATEC 2008 it will soon start incorporating fuel cells in a number of its products, i.e. digital cameras and notebooks.

The company currently presents a hybrid prototype of the W55T [JP], a cell phone that is powered by a methanol fuel cell (cartridge capacity: 50ml) charging a secondary lithium-ion battery. The phone, which is already available without the fuel cell feature, will go on sale in Japan in March 2009 at the latest.
