	Same as the first, save that the lower brush is
	driven from a DC supply, to allow faster build up,
	higher currents.

	Could be but:
	Injection source needs to be DC.  Tesla coils are
	mostly AC.

	Also:
	15KV or so is plenty for the injector, mostly.
	Using a TC system for this would be MASSIVE over
	complication.  (eg: CRT supply, laser toner
	ion spray supply, etc, would be apropos.)

	(Olde Phart Story:
	Buddy of mine in HS hotwired The School TV Set
	video B+ to the HS van De Graaff attempting to
	do this.  Sort of worked....)

	Takes some care.  van de Graaf currents go up with
	such a rig....
