Hightide – Radiometer


A radiometer is an invention from 1870 by the British physicist William Crookes, who called it a ‘light mill.’ Originally, radiometers served as laboratory instruments to investigate the conversion of light energy into kinetic energy.

The wings of the radiometer inside the evacuated glass bulb are activated by electromagnetic radiation, e.g., light. The rotation speed of the radiometer changes depending on the light intensity and the light source. When more sunlight or other “warm light” such as incandescent bulbs falls on it, the rotation speed of the mill changes.
