Dance if your mobile battery dead

Mobile Phone operator Orange said to produce a recharge powered by dance energy .

This year the portable kinetic energy charger will be test run. In the Glastonbury Festival, the world's biggest green field music and arts celebration that begins on a farm in Somerset, southwest England on Friday.

Orange said the prototype chargers weigh the same as a phone and are about the size of a pack of cards.

Attached to the user's arm, they employ a system of weights and magnets which provide an electric current to top up charge in a storage battery. This can then later be used to recharge the phone.

"We wanted to create a fun, engaging and interactive product which would encourage users to have a laugh while charging their mobile phone and at the same time test out a new energy-efficient prototype," said Hattie Magee, Head of Partnerships at Orange UK.
