It looks like a battery-eating iPhone case, but the reNEW Solar Battery Charger concept is actually a clever little device that spits out fully-charged batteries while attaching to your windows with suction cups. Your back-of-the-house, no-one-will-actually-see-it-here window. Updated.

The way you'd use the reNEW charger is simple. You toss your batteries in the top portion and they'll be ready at the bottom once they're fully-charged. Cool idea, but I'm not entirely sure that I'd want to plaster my windows with it.
