Brilliant, simple idea. Kick a soccer ball around, have it capture some of the energy, then give a plug so you can get the energy back out. Then give it away in Africa.
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.
In most African countries, 95 percent of the population is living off-grid with no access to electricity. With sOccket, people in developing nations will no longer need to walk 3 hours simply to charge their cell phones. The power will—quite literally—be in their hands. The sOccket ball can be used to light an LED lamp, or charge a cellphone or battery.
