Last week Apple introduced us to a Smart Home Energy Management System that had every tree hugging site on the planet cheering Apple on to the n-th degree. Well today's patent application from Apple should provide an encore for this audience, because Apple is seriously working on reinventing their media players to operate, for the most part, using solar cell panel technology; Panels that could cover a portion of the front or back covers of portable devices that are made from a transparent or semi-transparent material. One of the cool factors to Apple's technology is that if one or more of the solar cells are obstructed from a light source, the voltage output of the solar cells can use a technique described as first and second cell chain reactions to ensure that the device retains a constant source of power. The system works with a regular battery to ensure that in times of complete darkness the media players will still be functional. What will they think of next?
