One of Apple's more interesting patents kicking off 2010 revealed their aspirations of engineering solar powered media players. In Apple's second patent on this very subject we get to peek at more of the detailing behind their engineering vision. Yet it boils down to two main points. Firstly we see that Apple envisions utilizing solar cell technology right across the board from iPod to iPad. Secondly and perhaps most intriguingly, we see Apple detailing how they'll be able to integrate cell panels beneath their multi-touch surface as opposed to it being applied to the top surface of their media players as previously thought. This revelation ensures us that Apple won't be sacrificing design for function. The reason that it's intriguing is that it supports the design shift that Apple's iPhone prototype took. By switching the iPhone's backside substrate to a non-metal surface would clearly open the door for Apple to implement a double-sided solar panel design. This would double the amount of power that the cells would be able to draw in order for them to power the media player longer. While this technology won't be ready for primetime in 2010 to be sure, we could seriously see this power assisted technology make its debut sooner than most skeptics think.
