What gap in the secondary circuit? I see a ball located just inside
the tank connected to a gap outside the tank. The arrangement is
designed to measure the output voltage by the external gap being
calibrated to fire at a known voltage and the ball inside acting as
the pickup point for what is essentially a voltage divider. In the
fact the secondary as shown isn't directly connected to anything and
it appears that the apparatus as shown is useful only for finding out
how high a voltage the machine is generating given its energy input.
