True except if the "plate" is not there and all we have is a tiny bit of wire, and we don't want a relative voltage but an absolute excess of electrons in a part of a circuit that is starved for electrons (constantly giving them up to the environment)... I am correct in stating that a VDG would stop working, if the part that sprayed charges onto the best was not able to replace them. > > > >> , removal of its support (the > >> plasma) won't make it disappear.

Well that can tend to happen, however the collapsing plasma gives them great velocity (they pass through the glass), also in the design they are effectively on the inside of a cylinder which acts much like a Faraday cage, they don't see the electric field of this "plate" while inside, but the "plate" is a wire mesh designed to avoid collisions with speeding particles, a but like the reverse of a Farnsworth fusor electrode which successfully avoids too many collisions despite the fact the particles are attracted to the wire. I think you need to read my "On Topic" post to appreciate what I am talking about. It points out that charges are emitted from disrupted electrical circuits and deposited on distant metal objects, this phenomena has a quality of speed unlike ion wind and is very well reported/proven.
