An evacuated glass bulb encloses a rotating shaft with vanes painted black on one side, silver on the other.
WebDec 3, 2024 · Crookes' Radiometer. This strange looking windmill is locked in an airtight chamber at near vacuum conditions, so how the heck is it moving? The answer is light! This isn't a windmill; it's a light-mill! Chemist William Crookes accidentally stumbled upon the effect and created the contraption in 1873. WebFor this Fermi estimate, the details of the ramp (e.g. exponential vs linear, factors of 2 or e) are not significant, so our very rough estimate for the mechanical output power of the radiometer is. P o u t ∼ 0.03 J 10 s = 0.003 W. so the efficiency estimate is. P o u t P i n ∼ 0.003 W 0.2 W ∼ 1.5 % ∼ 10 − 2.

WebA Crookes radiometer consists of a glass bulb from which most of the air has been removed, thereby creating a partial vacuum, and a rotor that is mounted on a vertical support inside the bulb. The rotor bears four light, horizontal arms mounted at right angles to one another on a central pivot; the rotor can turn freely in the horizontal plane.
