Hydrogen fuel cells could soon have an impact on fashion, says Xybernaut of
Virginia. The firm wants to use fuel cells to power its wearable computers. With
batteries, Xybernaut鈥檚 mobile computer runs for only three hours, but using a
prototype miniature fuel cell developed by DCH Technology of Valencia,
California, it can run for 24 hours. The cells generate electricity by 鈥渂urning鈥�
hydrogen in a controlled manner, producing water. Storing the highly flammable
hydrogen will be a challenge. The firms hope the complete product will weigh
less than a kilogram.
