  • How does a Crookes radiometer work? - HowStuffWorks
    A Crookes' radiometer consists of an airtight glass bulb with a partial vacuum and a set of vanes that spin when light is shone on them The spinning of the vanes is attributed to thermal transpiration, where light heats the black side of the vanes, causing the air on that side to be expelled faster and the vane to move away from the light source
