A T-shirt, that can charge phones using vibrations

Glastonbury revellers may have an extra incentive to elbow their way through the mosh pit and closer to the stages - it may help charge their mobiles.

A prototype T-shirt has been designed to power mobiles while festival-goers watch bands in action. Users can plug their phone in to the shirt, which uses noise-responsive technology, for a quick top-up charge whenever they need it.

Mobile phone giant Orange will be conducting live testing of the device on site at the festival this weekend to see which acts and beats are the "best to charge to" around the Spirit of 71 stage.

Tony Andrews, co-producer of the Spirit of 71, said it could provide "a real solution to mobile phone charging" while on the go.

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

The T-shirt's release comes at the same time a Japanese company announced it has come up with another way to charge your mobiles after a natural disaster or in the great outdoors - by heating a pot of water over a campfire.

TES NewEnergy, based in the western city of Osaka, said the new gadget turns heat from boiling water into electricity that feeds via a USB port into digital devices such as smartphones, music players and global positioning systems.

The Hatsuden-Nabe thermo-electric cookpot invention went on sale in Japan this month for £186 (Y24,150).

The company said it takes three to five hours to charge an iPhone - and can heat up your lunch at the same time.
