Designer Margot Krasojevic has developed a very unique piece: a 3D printed light that provides its own power. How does it do that, exactly?
The shape of the case is the secret. While it appears to be an attractive lamp, aerodynamically its actually a propeller! It's mounted on a rotating axis connected to a tiny generator that produces power when the wind turns the propeller.
Once again, something useful is created using the unique properties of 3D printing technology.
