SolePower is another contraption that lets you charge your smartphone through a very basic action that everyone does at some point during the day: walk. Similar concepts have been proposed before, but a group is finally taking action and their proposed device is called SolePower. It’s dubbed as a “power-generating shoe” that allows the wearer to charge portable electronics like smartphones, MP3 players, and tablets as they walk.
Instead of being embedded into the actual shoe, SolePower is a separate, removable insole that you can swap and insert into whatever pair you’ve chosen to wear.
SolePower is currently in its alpha prototype phase. Its creators have launched a Kickstarter campaign with the goal of raising $50,000 so they can start working on a version that can be mass produced. You can get your own pair by pledging at least $100.
