Crookes Radiometer

Description:

The Crookes Radiometer is a device that converts light radiation into rotary motion. It has an airtight bulb with a partial vacuum for measuring radiant energy. Inside the bulb is a set of vanes which are suspended on a spindle and rotate when exposed to light. The bulb is crystal clear polycarbonate with a plastic base. A perfect learning tool to help students understand thermodynamics.

Excellent demonstration tool of the effects of heat and the conversion of solar power to mechanical power. Consists of a set of vanes each shiny on one side to refl ect the light and blackened on the other to collect the energy. It is mounted in an evacuated glass bulb. When exposed to the sun or source of intense light it causes the vanes to spin.
