We ’ve seen battery charged by outlets and by grump , but this conception from designers Song Teaho and Hyejin Lee is the first that explosive charge with a whirl .
However , like all things tagged concept , this electric battery does n’t * technically * exist yet .
Still , Teaho and Lee both theorize that this stamp battery , should it become the literal flock , would require about 130 whirl for two - moment talk sentence .
From what I ’ve seen of grump - charged electric battery , that seems comparatively plausible ( and tiring ) . Get to study , fellas . [ design(dot)frviaEngadget ]
