: Effect of Light on the Speed A Rotating Radiometer Science
The radiometer was invented by Sir William Crookes in 1873. Crookes' radiometer is the result of serendipity, the act of making unexpected discoveries when looking for something else. In this case, Crookes was looking for a means to weigh very small amounts of chemicals as part of his research (the research eventually resulted in his discovery of the element thallium).

: How does a light-mill work?
In 1873, while investigating infrared radiation and the element thallium, the eminent Victorian experimenter Sir William Crookes developed a special kind of radiometer, an instrument for measuring radiant energy of heat and light. Crookes's Radiometer is today marketed as a conversation piece called a light-mill or solar engine.

: How efficient is the Crookes radiometer? - Physics Stack Exchange
It is hard to make a precise determination of the efficiency, but we can make a Fermi estimate that it is of order $10^{-2}$.. Efficiency is the ratio of output to input, but even defining the input here is not easy. A 100 watts of heat is mentioned, but what does that mean? Is 100 watts of light shining on one of the radiometer vanes or is 100 watts of heat applied over the radiometer's glass ...

: The Crookes’ Radiometer: Apply Light Pressure
I first encountered the Crookes’ radiometer as a child, when I saw a storefront display with a couple dozen of them: light-bulb-shaped things with odd little vanes inside. I had no idea what they were or how they worked, but I was impressed. Years later, in high school, my physics teacher explained how a radiometer operates.
