   For historical purposes..
I could mention that in France (?) at one time, consideration was
given to an analogous machine, using 'dust particles' suspended in
a closed, airflow driven circuit. (plumbing.).  Corona combs
would have been sealed into the tubing, etc, etc.

I've no idea if the machine was ever built/tested...>>

This machine had been conceived around 1936 by M. Pauthenier and all. (La
Sorbonne , Paris ) They proposed  to used a flow of charged particles ( glass
spheres of a few microns in diameter), circulating in a closed insulating pipe
instead of the classical belt of the original apparatus. A blower produced a 60
m.p.s flow of these particles in the loop pipe. In 1937 a Pauthenier
Generator produced a voltage of about 1,8 MV.

This design was still described in first patents of Van de Graaff.
