Necessity is the mother of all invention, but creativity is no man’s legacy. We’ve seen some innovative bike chargers for cellphones, created out of necessity maybe, and now here’s a creatively thought charger concept by Soledad Martin. So whether you’re a skateboarder, or an athlete, or just fond of walking, this nanogenerator or charger, which creates electricity through kinetic energy, is what you need. The charger can be tied to the shoe, so that whenever you’re involved in some activity that requires walking or running, you are creating enough energy to power your cellphone via its USB port.
