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.

so the efficiency estimate is. Pout Pin ∼ 0.003W 0.2W ∼ 1.5% ∼ 10−2 P o u t P i n ∼ 0.003 W 0.2 W ∼ 1.5 % ∼ 10 − 2. This is not great, and the effective efficiency would be much, much worse if instead of only considering the sunshine hitting the vanes for Pin P i n, we included all the light averaged over the radiometer enclosure.

First I got out the tripod and took some video of the spinning radiometer using my Olympus TG-3 point-and-shoot camera. (Conveniently, this camera has video capabilities up to 240 frames per second which will be useful when the radiometer is really spinning fast.) My plan of attack was to pick a pixel on the video and get a trace of the …

A light mill is also known as a Crookes radiometer: It seems like a simple thing: an evacuated glass bulb with some vanes that can spin around, black on one side and white on the other. When you shine light on it, it spins. Look which way it spins. It seems the light pushes harder on the black side of each vane than on the white side.
