Power, wherever we can find it.
We don’t have to try too hard to generate power. The energy it takes to produce just one breath is equal to about a watt, for starters. It’s no surprise then that researchers around the globe have been searching for ways to harvest energy in the unlikeliest of places. From the kick of a soccer ball to a stroll across the sidewalk to the flying of kites, the possibilities for generating energy are endless. We rank them on a scale from 1 (dim future) to 5 (bright idea).
