This is the most cool thing I've ever seen on iPhone, Orange has
developed a t-shirt that can charge your iPhone by absorbing sound and
converting it into useable energy. Sounds crazy, and let's have a look
the Sound Charge T-Shirts theory:
The Sound Charge uses an
existing technology in a revolutionary way; by reversing the use of a
product called Piezoelectric film within a specially designed t-shirt,
allowing people to charge their mobile phones whilst enjoying their
favourite act at Glastonbury.
