Re: Concentric spheres- an hypothesis

Actually a lot of work has been done on this very subject by Prof. 
R.G. Herb, Univ. of Wis. alumnus, now the Chairman of National 
Electrostatics in Middleton, WI.

Prof. Herb published several papers on on the use of concentric 
shells in very large Van de Graaff generators, many of which were 
used at Sandia National Labs during the Manhattan Project (building 
the first A-bomb).  I don't know how many of them are still classified though.

Concentric shells Van de Graaffs allowed better control of the 
powerful electrostatic fields in tandem VDGRFs.  The physics is well 
understood in this area of research.
