Recorded or estimated? Also, BPS has nothing whatever to do with

That was reported in O'Neill's biography. I would take such reports
with a very large dose of salt. Clearances between the mast leading
up to the tower and the opening in the roof were ?? My suspicion is
that a mains resonant in the primary charging circuit was
responsible. That, or possibly the kind of kickback that kills the
insulation in our beloved NSTs? Note - the generators were miles
from the gap system.

He saw the earth as a confined conducting medium which concurs
with that view. It is a terribly lossy medium none-the-less.

Robert Golka reconstructed the CS machine in the hopes of making
ball lightning. There is no record that he succeeded in that goal
either. In fact, his reversion to the use of large accumulators melting
iron attests to his lack of success. Surely high power machines
(some modern ones operating at far higher powers than Tesla ever
did) should be causing all sorts of mayhem ?

It has been done and nothing unexpected has resulted from the
