Move your body, charge your phone
Dance Charge uses the kinetic energy generated by your body in motion to juice up your phone.
There are several ways one can harness natural energy. In addition to the sun, wind, tides, and geothermal activities, the human body itself is increasingly being used to produce energy charge all sorts of electricity-hungry devices.
Music company Orange and GotWind, a firm specializing in renewable energy, have teamed up to create a device called the Dance Charge. Weighing 180 grams (about 6.3 ounces), you strap it around your arm. Dance Charge then uses the kinetic energy generated by your body in motion to juice up your phone.
It also uses a system of weights and magnets to produce electric current to top up the storage battery, which can later be used to charge your handset. A prototype of the device will be shown and tested at this year's Glastonbury Festival.
