Could your next Apple MacBook laptop be powered by hydrogen?
The AppleInsider website recently uncovered two patent applications filed by the Apple Company with the U.S. Patent and Trademark Office: "Fuel Cell System to Power a Portable Computing Device" and "Fuel Cell System Coupled to a Portable Computing Device."
Hydrogen-based fuel cell technology isn't new. But rising consumer interest in renewable energy source—as exemplified by the demand for alternative-fuel cars, such as the all-electric Nissan Leaf and gas-electric Chevy Volt—is also spurring Apple apparently. In both patent applications, Apple states:
As a consequence of increased consumer awareness, electronics manufacturers have become very interested in renewable energy sources for their products, and they have been exploring a number of promising renewable energy sources such as hydrogen fuel which is used in hydrogen fuel cells.
Apple proposes in its patent applications that fuel cell systems could power a portable computer "for days or even weeks without refueling." But cost and weight of the mobile fuel cell systems are obstacles that still need to be overcome, Apple acknowledged.
