One of the drawbacks of current battery technology in our electronics is that they don’t last very long. Our smartphones and laptops barely get a day’s worth of battery, or even less if you’re a power user. Stuffing larger batteries inside them could fix the problem, but it’s not necessarily a long-term solution.
A long-term solution would be to come up with better battery technology, and that’s what Apple seems to be doing. In a patent discovered by AppleInsider, it seems that Apple is exploring the idea of maybe using hydrogen fuel cells to power future iPhones and MacBook laptops. The company cites environmental concerns of using current battery technology, and also the advantages of hydrogen fuel cells.
According to Apple, “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.”
They add, “Hydrogen fuel cells have a number of advantages. Such fuel cells and associated fuels can potentially achieve high volumetric and gravimetric energy densities, which can potentially enable continued operation of portable electronic devices for days or even weeks without refueling.”
However, given that this is only a patent, it’s hard to say if it will come to fruition, but an iPhone or a MacBook that could last for days on a single charge certainly sounds rather appealing.
