Orange Sound Charge T-shirt will juice up your phone while you listen to the bass go boom

Orange UK has a long-running tradition of coming up with quirky ways to recharge your phone while enjoying the Glastonbury Festival every year, and 2011 is proving no different. This time around, it's a T-shirt that generates an electric charge from the sound around it -- rendering it ideal for front-row crowd-surfing types -- though the provided tech details go no further than to tell us that piezoelectrics and the absorption of vibration are involved. We find ourselves overcome by the suspicion that you'll never be able to get much meaningful utility out of this rather unstylish garment, but then it does give you a plausible excuse for pushing your way nearer to the stage, and if anyone objects, you can consider it a great conversation starter. So whatever happens, you win, fashion loses.
