Energy Generating Soccer Ball Brings Clean Power to Off-Grid Areas
“The ball works by capturing kinetic energy through an inductive coil mechanism, which works in a similar manner to those flashlights that are powered by shaking. As the ball is batted about, it draws a magnet through a coil, creating current that is stored in a battery. According to the designers, the device weighs little more than a standard soccer ball, and 15 minutes of play produces enough energy to illuminate a small LED for three hours.”
