Miniature fuel cells will change the world as we know it. Fuel cells can serve as power sources for a limitless array of personal electronics. For instance, fuel cells will power laptop computers and palm pilots for hours longer than batteries. Fuel cells will enable you to talk much longer on a cellular phone without recharging. Other applications for miniature fuel cells include pagers, video recorders, portable power tools, and other devices such as hearing aids, smoke detectors and burglar alarms. These miniature fuel cells generally run on methanol, an inexpensive wood alcohol also used in windshield wiper fluid.
