Summer is the festivals season, where thousands of groupies gather around stages, equipped with camping tents and cellphones, dancing all day long, as the music rocks and the beer pours down for 3 days of euphoria. To keep your mobile devices charged, telecoms company Orange has decided to test a new mobile phone dancing charger at the Glastonbury Festival in the UK. This experimental Dance Charger prototype works on kinetic elements, allowing to convert your movements into generated energy in order to charge your attached handset. Designed as an arm strap, the 4.25 x 2.5-inch velcro and elastic band houses weights and magnets that produce an electric charge, once you wave with your hand or shake your body. As mentioned, it was presented at Glastonbury 2 weeks ago, but you might find it in some other places, so if you happen to be in one of those summer festival and need to charge your phone, just hand it to Oranges Dance Charging Man to see if it works.
