Generate Electricity While you Play
Energy Harvesting is a growing field that may become significant in our lives someday. Here’s a link to a great article on harvesting energy from a soccer ball. Looks like it’s making a debut on Kickstarter, too.
While the article isn’t explicit about real world application, I imagine a model where the kids go out to play soccer for an hour or two and then the ball is brought back so the energy can be consumed. What I’d like to know is do child labor laws apply? 😉
