One of the drawbacks of modern battery technology in electronics is that it doesn’t last as long as you’d like. A rare smartphone or laptop can work in active mode all day. Using larger batteries could solve the problem, but not drastically.
A completely different, more advanced battery technology could be a long-term solution, and Apple seems to be already working on it. In a new patent, Apple reveals the idea of using hydrogen fuel cells in future iPhones and MacBooks. The company cites the environmental challenges of using modern battery technology as well as the benefits of hydrogen fuel cells.
Apple’s continued reliance on fossil fuels has forced the US government to maintain difficult political and military relationships with unstable governments in the Middle East, as well as exposed its coastlines and citizens to the dangers of offshore drilling.
Apple adds: “Hydrogen fuel cells have a number of benefits. Such fuel cells and associated fuels have the potential to provide high volumetric and gravimetric energy densities, which could potentially allow portable electronic devices to operate continuously for days or even weeks without charging.
However, given that this is only just a patent, it’s hard to say if it will be implemented, but an iPhone or MacBook that can last for days on a single charge certainly sounds pretty good.
