What whether you could recharge your phone battery by twirling it around your finger? That’s what a design concept Song Teaho and Hyejin Lee promises.

The yet unnamed battery design is similar to your normal cell phone battery. But thanks to the gap on one end, it’s possible to spin the potential pack around a finger, converting kinetic motion into useful energy. According to diagrams showcasing the design (see pictures above), 130 twirls makes up to 2 minutes of talk moment and 25 minutes of standby.

Unfortunately, that yet another design concept, with no official word on when that design will hit the mass market—if at all—and at what price. Let’s see whether Teaho and Lee can find some backers, and hope that putting a gap in a cell phone battery doesn’t lead to a significant loss in lifetime.
