A Charged Battery Is But 130 Twirls Away

We've seen batteries charged by outlets and by cranks, but this concept from designers Song Teaho and Hyejin Lee is the first that charges with a twirl.

However, like all things tagged concept, this battery doesn't *technically* exist yet

Still, Teaho and Lee both hypothesise that this battery, should it become the real deal, would require about 130 twirls for two minutes of talk time.

From what I've seen of crank-charged batteries, that seems relatively plausible (and tiring). Get to work, fellas. [design(dot)fr via Engadget]
