It might not change the world, but it won't be for lack of trying. Plus Minus Solar has designed what it's calling the LED Solar Pebble, a multifaceted device that requires just a pinch of sunlight (or maybe gobs of it, actually) in order to generate artificial light. And charge your arsenal of gizmos. It's engineered to be built at a low cost and used in developing nations, but unfortunately there's no confirmation on what exactly it'd charge. 'Course, it's just a concept as of now, so we're guessing a micro-USB and mini-USB socket could be tossed on by whatever manufacturer would be kind enough to get this to a production line. Right, prospective manufacturers?
