Oh, good, can I help?

Yup. No current, no energy transfer, no light.

Er, recall that charge _in motion_ = current.

Along about here I started wondering whether anyone else
is noticing the 'capacity area' of the topload and the
'capacity area' to be added to the fluoro tube form a
capacitor. In order for the tube to carry current, the
current has to get past the capacitor.
Now, most of us will agree that this will work in a
vacuum. Is this a demonstration of displacement current?
