Re: Fusor Capacitance

It may be difficult to separate "theory" from "application," but let''s see if this helps facilitate the discussion.

Can you explain what you mean by "sheet" capacitance?

This is an old concept and is part of electrostatic theory.

Basically, If you make a hollow chicken wire sphere (or geodesic) of some size whereby the holes are a small enough fraction of the sphere's surface area the device has the same isotropic capacitance as that of a perfectly smooth and solid sphere. At some further point of closure of the holes, the field about the hollow wire sphere will also be close to having no detectable field irregularities over that of the solid ball either.

With the inner grid of a fusor, we are, capacitively, close to a perfect solid ball but no where near a smoothed out field near the surface.
