The radiometer, also known as a light windmill, is a instructive physical object for demonstrating a theory, which was invented by the English physicist Sir William Crooke in 1873. This small physical and technical miracle shows in a simple way how the smallest sun power plant in the world converts light into energy. Depending on the power of the light, a rotation of approximately 2000 revolutions per minute can be reached by the radiometer.
