This article focuses on a revolution in mobile technology. Driven by demands from users for smaller, lighter and highly functional devices with longer battery lives, manufacturers are working on incorporating leading-edge technology into their mobile devices. Long-life batteries will be a key component of future portable devices. Some industry watchers have recognized that a revolution is under way to move from traditional batteries to more efficient 'fuel cell' batteries. Early tests from Toshiba have already shown they can power a notebook for five hours. The fuel cell battery is fed by a small cartridge of methanol and works by converting chemical energy into electricity. The by-products are oxygen and water, which are recycled back into the cell. Steve Crawley, head of product marketing at Toshiba, said that fuel cells will be a big thing because they are very energy efficient. It is also easy to change a fuel cartridge. People may also perceive it as being a greener technology. Crawley anticipated seeing fuel cells in notebooks in two to three years' time.
