Power to the people, and power from the people. When IBM came up with a list in 2011 of the five technologies it thinks will change the world in five years, kinetic energy--power from people--topped the list. Advancements could come, they say, from developments in devices that might harvest power from your shoes, your exercise, and even the soccer ball you kick. Green gyms are also cropping up. And now the idea has come to playgrounds, where kids’ movement can be harnessed and funneled into powering schools and toys.
