Apple is planning to make devices powered by hydrogen fuel cells, according to patent applications published by the U.S. Patent and Trademark Office.
The plans could create computers and phones with weeks-long battery power. It would also make the devices lighter and less bulky.
According to the Telegraph, hydrogen fuel cells work by converting hydrogen and oxygen into water and electrical energy. This technology is already being explored for cars and the military.
"Our country's continuing reliance on fossil fuels has forced our government to maintain complicated political and military relationships with unstable governments in the Middle East, and has also exposed our coastlines and our citizens to the associated hazards of offshore drilling," reads the patent application. "These problems have led to an increasing awareness and desire on the part of consumers to promote and use renewable energy sources."
This won't come as much of a surprise to those who follow Apple closely. The company has filed several other patent applications for similar technology, as reported by Apple Insider in October.
