I don't think an ungrounded VDG would stop working, potentials are relative, you could replace the ground by a large plate at any potential wrt ground, and the VDG would still generate the same voltage relative to that plate as it was generating wrt ground. >> , removal of its support (the >> plasma) won't make it disappear.

I meant the capacitor's other conductor (the plate), to which the orphan charges will be attracted preferentially because they are close and of the opposite sign. If there is a dielectric in between, they will simply stop on its surface IMHO. Michel
