There are several ways one can harness natural energy. For example, the wind, the sun, tides and geothermal activities, and increasingly, the human body to producer energy to charge all sorts of electricity-hungry devices.
Music company Orange and
GotWind, a firm specializing in renewable energy, have teamed up to create Dance Charge. Weighing 180g, 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 on June 27 at this year's
Glastonbury Festival, the world's biggest greenfield music and arts celebration.
