Charge your iPhone once a week … This sweet dream might become real. Well almost… The British company Intelligent Energy presented a hydrogen battery that would keep an iPhone charged for seven days! The prototype would be a similar size to the lithium-ion battery present in the current iPhone. It would be composed of a rechargeable battery and a micro fuel cell while in two fans in the rear of the smartphone would provide an exit for the water vapor generated by the mixture between hydrogen and oxygen. The charging iPhone will be made through the headphone jack hole. Intelligent Energy would be working on this project in close collaboration with Apple. Unfortunately, according to the company spokesman, which already proposed taxis running on hydrogen during the London Olympics in 2012, « it might a few years » … So far you will still need a mobile battery to stay connected throughout the day.
