There's a bunch of cell phone charger alternative (like solar chargers or using batteries) but this one is unique: it's a phone charger powered by dance!
Orange today unveiled a prototype phone charger which harnesses the kinetic energy of your dance moves to allow you to make calls.
The device - which weighs 180grams and measures about the same size as a pack of cards - will be strapped to peoples arms and tested at Glastonbury Festival this week.
As the dancers moves their arms along to the music – a specially designed system of weights and magnets creates an electrical current which provides a top-up charge to a connected mobile phone.
