Mobile phone operator Orange said on Tuesday that it had teamed up with GotWind, a firm specializing 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 begins on a farm in Somerset, England. 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 completely charge a storage battery. This can then later be used to recharge the phone. This is another breakthrough for a world that is engage in an Environmental Crisis.
