A soccer ball generates electricity while being kicked around

Yes now Africans parents will tell their children it's time to go play football :-)

A team of four engineering students at the Harvard University have come up with an ingenious idea that could change the lives of rural African people. The students have designed a unique soccer ball that generates electricity when being kicked around.

Dubbed the SOccket, the ball captures the energy from impact that is usually lost to the environment. The generated electricity is then stored in the ball, which after dark can be used to light an LED lamp or charge a cell phone.
