A new gadget has been developed so your own dance energy can be harnessed to boost mobile phone batteries.
British mobile phone operator Orange says it has teamed up with GotWind, a firm specialising in renewable energy, to produce a recharger powered by dance energy alone.
The portable kinetic energy chargers will be given a test run at this year's Glastonbury Festival, the world's biggest greenfield music and arts celebration that opens on a farm in Somerset on Wednesday.
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 that provide an electric current to top up charge in a storage battery.
This can then later be used to recharge the phone.
A spokeswoman for Orange UK said the company wanted to create a fun, engaging and interactive product that would encourage users to have a laugh while charging their mobile phone and at the same time test out a new energy-efficient prototype.
