Awesome!
Jessica Lin and three other female Harvard University students—Jessica Matthews, Julia Silverman, and Hemali Thakkar—created sOccket to produce a soccer ball that generates cheap, clean, off-grid electricity when rolled. The sOccket ball captures the energy from impact that is normally lost to the environment when the soccer ball is kicked, dribbled, or thrown and stores this energy for later use.
Their project started as a team project for an engineering sciences class at Harvard. They were inspired by dance floors that capture the energy of dancers jumping and moving around.
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.
