Dead Cell Phone? Just Dance! 
We’ve all been there. You’re at an all-day event like a music festival or work function with no way to charge your dead cell phone battery. What can you do? Try dancing! With this unique invention you can charge your phone or other small electronic devices just by moving around.
Mobile phone operator Orange UK recently announced teaming up with GotWind, a firm specializing in renewable energy, to produce a charger powered by dance energy alone. According to Orange, the prototype chargers weigh the same as a phone and are about the size of a deck of cards.
The charger attaches to the user’s arm and through a system of weights and magnets provides an electric current to charge a storage battery, which can then be used to recharge the phone. So now, with the help of some smooth moves, you can be back in action and connected to the world again in no time.
