I have never, on a single resonator, found one instance where the spark
"turned around" or started to drop off with any size toroidal increase,
provided I poured in more energy.  I am confident the limit is very remote
and is as Tesla said limited purely by the geometry of the system,
insulation, air breakdown and the ability of the experimenter to control the
intense electric field energy.  I think maggey 11-E is a prime example where
a 12" tall 4" diameter coil is now throwing 11 foot arcs!  I am now
"building limited" and have little doubt that the 11 foot arcs could be
increased if only I had the room.  RH
