Charge the battery with ... dance

What do you do when you're stuck in a cramped pop show like a wedge, but the cell phone in your pocket is going to turn off because of the battery out?

But thanks to a brand new device, all you need to do is listen to music and . dance. The battery will be full again and the phone will call again normally.

Sounds like a myth?

Yesterday, British mobile network Orange said it would cooperate with GotWind to produce a rechargeable battery capable of charging with . body energy generated when dancing.

GotWind is a technology firm specializing in recycled energy and clean energy.

This "dance" battery (temporarily called it) will be tested at the Glastonbury 2008 Music Festival, scheduled to open in Somerset, southwestern England on Friday.

According to Orange, the rechargeable battery model will have the same weight as a mobile phone and is about the same size as a deck of cards.

When worn on the user's hand, the magnetic magnet system will automatically activate. Every time a user's body is physically active (such as when dancing), the energy generated by the muscle will be "sucked" to store it in a storage battery.

Later, the storage battery will "power" the phone when needed.

"We want to create a product that is both highly applicable, interactive and fun. Users will both charge the phone and feel refreshed, happy .

Equally important is that we save energy and protect the environment , " said Hattie Magee, Orange's Director of Cooperation.
