Product Details

Solar Engine Radiometer

Invented in the 1860's by William Crooke, it is also referred to as Crookes Radiometer or a light-mill. It is typically used to demonstrate the active conversion of light energy into mechanical energy. Within the evacuated glass bulb, a rotor rests atop a pin or nail with a sharp point, allowing the vanes to rotate. One side of each vane is light, while the other is dark. The darker vanes allow for the absorption of light rays, while the lighter vanes reflect them. This fascinating property of color allows for the entire rotor to spin around the tip of the nail or pin, as it converts light energy into mechanical.

The intensity of the light is directly proportional to the amount of energy transferred. As the intensity of the available light increases, the vanes will spin faster and faster. As the intensity begins to diminish, the vanes will start to slow down.


The radiometer measures 4.6x3.6x3.6" (HxWxL), and has a diameter of 3.1 inches.
