sOccket to me!

...four Harvard students are betting that the popularity of soccer around the globe can help reduce the use of kerosene.

They came up with the idea for the sOccket, a soccer ball that generates and stores electricity during normal game play. The stored electricity in the ball can then be used to light an LED lamp, or charge a cellphone or battery.

“Soccer is something you will find in every African country,” one founder, Jessica Lin, told Green Inc. “People play for hours a day, so we thought, ‘Why not try to get a little more out of that energy?’ and that’s where the idea ultimately came from.”

...Early prototypes of the ball use an inductive coil mechanism similar to the technology found in shake-to-charge flashlights. The movement of the ball forces a magnet through a metal coil that “induces” voltage in the coil to generate electricity. For each 15 minutes of play, the ball can store enough energy to illuminate a small LED light for three hours, according to initial trials.

Now if we could only get that kind of performance out of our politicians!
