Consider a scenario in which your mobile phone’s battery is about to run out and you see no possibility of recharging it. What will you do in these situations? Mobile phone operator Orange has come to our rescue in these situations as it has planned to fabricate a recharger powered by dance energy alone. It has teamed up with a firm called GotWind which is currently specializing itself in renewable energy. The prototype chargers are about to weigh the same as a phone and their size is comparable to a pack of cards. They are attached to the user’s arm, which is said to employ a system of weight and magnets that in turn supply electric current that boost up the charge in the stored battery.
