As far as car accessories go, we have to admit this one looks pretty silly. But the Samsung scientists who made it could also be onto something. The flapping tongues inside are actually coated with gold, and when they rub up against a smooth plate, electricity is created through something called the triboelectric effect. It could be a whole new way to harness wind energy.
