Generating electricity while playing sports, it's a combination that doesn't immediately come to mind when I think of a game of soccer. Still, four Harvard students managed to design a soccer ball that generates electricity when being kicked around. Why let movement go to waste when you can convert it to valuable electricity?
Designer Kyung Guk Lee came up with a cool idea, a skip rope that lets you recharge batteries. Skipping for about 20 minutes will not only burn fat but allows the E-Rope, as the product is called, to fully recharge an empty AA battery.
