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.
"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."
