Solar-powered mobile phones will keep you talking
It’s an idea so brilliantly simple, you wonder why Nokia didn’t do it five years ago. Annoyed at the way your mobile phone battery always seems to go flat just before an important call? Then stick a few solar cells on the back so it can charge itself up via the sun’s gleamy goodness. Job done.
Chinese firm Beijing Hengjiweiye has just shown off its solar-powered phone prototype, at the China Beijing International Expo 2007. Okay, so it’s not the prettiest device in the world, but it’s a start. And they’re not the only company working on solar phones either.
