This soccer ball is more than just fun and games: the Soccket stores the kinetic energy generated as the ball is kicked around. A removable tab on the surface of the ball covers an electric outlet, where an LED lamp or cell-phone charger can be plugged in. A half-hour of play should translate into three hours of light or, when fully charged, provide power for 72 hours.
As you play with the Soccket, a small pendulum inside the ball harnesses the kinetic energy of movement by turning a generator connected to a rechargeable battery. Simply plug the included LED lamp into the ball and you have a light!
The Soccket was designed by Harvard students Jessica Matthews and Julia Silverman, who originally were thinking of poverty-stricken countries where soccer is popular and electricity is unreliable or unavailable. But the ball and its six-watt output also could be useful at the beach, on camping trips or during blackouts.
The company Uncharted Play plans to sell the ball for $99 or less. It is available for pre-order now.
