Orange UK have announced they are planning to test a t-shirt at the upcoming Glastonbury festival which contains noise-responsive technology to produce a charging voltage from the sound of music. Plug your phone into the t-shirt and get yourself close to the music to enjoy a free charge of your device! Orange will be conducting live testing of the gadget on site at the festival to see which acts are the "best to charge to" around the Spirit of 71 stage.

Tony Andrews, co-producer of the Spirit of 71, said:

Sound vibrations, particularly bass frequencies, will create enough shaking to produce electricity from a material as simple as piezoelectric film.

"It looks like it could provide a real solution to mobile charging and I’m interested to see how the Orange Sound Charge performs in a live testing environment such as Glastonbury.
