The sOccket may look like a normal soccer ball. But flip open its secret panel and you'll discover that it "converts kicks and headers into off-the-grid power." Created by a New York nonprofit to benefit developing countries, the ball ($100) is made of a durable watertight foam rubber and generates energy thanks to magnetic rotors that are hidden inside. Future versions of the sOccket will be able to recharge a cell phone, but for now the internal battery can be used to power a water purifier or an LED lamp. Source: Popular Mechanics.
