Question

Did old Crookes Radiometers ever have a pair of terminals?

Answer 1

This is a question about old physics lab equipment.  This and this question led to the question in SciFi SE Crookes Radiometer at the end of a telescope in old movie scene, something about a comet? which led to the image below.  Of course one does not use wires to couple a radiometer to a telescope.  However, my question is about the (now old) Crookes Radiometer shown in the image from 1965. There are two terminals in the wooden base of the radiometer.

Answer 2

Hey !

Yes, they have a wooden base because the excess electricity may not harm the person using it.
