A closer look at the SolePower insole
Two years ago, University of Wisconsin–Madison engineering researchers Tom Krupenkin and J. Ashley Taylor developed a device designed to harness the power of walking to charge an internal battery. Now, a new product called SolePower is looking to do the same thing, and its designers are turning to Kickstarter to bring it to the masses. The difference between this and other devices is that it comes in the form of a removable insole, so it can be used in different kinds of shoes.
