Amazing:

Invented by a group of engineering students at Harvard, it’s a soccer ball that harnesses the energy of play, using kinetic and inductive coil technology.

After a session of footie, an LED lamp can be plugged into the sOccket, providing light for activities normally impossible after dark. A fantastic solution in many developing countries, in those areas where families have limited or no access to electricity, and often use kerosene to light their homes. Tested in South Africa after last year’s World Cup, it provided three hours of power after a mere fifteen minutes of play.
