Power play: electricity generating soccer ball

Three Harvard students have come up with “sOccket” – a soccer ball with an internal generator that in a typical game will generate enough power to provide light for a house for a day.

“The ball uses inductive coil technology–similar to flashlights that power up when shaken. Each 15 minutes of play with the ball generates enough power to light up an LED lamp for 3 hours, so a soccer game could easily provide light for a day.”
