Now that you mention it, thats right.  The knob hill Van De Draff had a lab
inside the spheres with people inside them.  A TC would be no different. But
I think potential difference is why its possible for someone to be inside.
There is no potential difference inside the sphere or toroid because
resistance is almost zero.
