Soccer Ball That Is Also A Portable Generator
Many children around the world don't have electricity but they do play soccer. The soccket is a soccer ball that captures energy with every kick. Fifteen minutes of play produces three hours of light.
The sOccket harnesses the kinetic (motion) energy of the soccer ball during normal game play and stores it for later power needs. After play, an LED lamp can be plugged into the sOccket to provide light for reading and other activities normally impossible after dark.
It's a clean, portable generator that can provide light to families in need around the world. Four Harvard students created this project for the American Express-sponsored Take Part program.
