Description

This product consists of a set of vanes, each with one shiny side and one black side, mounted on a spindle in a partially evacuated glass bulb. When exposed to the sun or other intense light, the vanes begin to rotate with the black side trailing. The black side heats the air next to it more than the shiny side, so the air pushes harder on the black side.
