Crookes radiometer - Wikipedia

To rotate, a light mill does not have to be coated with different colors across each vane. In 2009, researchers at the University of Texas, Austin created a monocolored light mill which has four curved vanes; each vane forms a convex and a concave surface. The light mill is uniformly coated by gold nanocrystals, which are a strong light absorber. Upon exposure, due to geometric effect, the convex side of the vane receives more photon energy than the concave side does, and subsequently the gas molec…Crookes Radiometer, Light Mill - Arbor Scientific,See the energy of light! The Radiometer features an evacuated glass bulb that encloses a rotating shaft with vanes painted black on one side, silver on the other. Light energy differentially warms the vanes' flat surfaces, imparting energy to the gas molecules which "kick" the vanes into a rapid rotation.
