Hi Terry,

I just got to this post.

This is good information.  Thanks.  If the potential remains
about 20KV, then each spark is releasing 2950 hp.  Tesla
commented on this several times.  It's pretty amazing that the
copper pipe picks up 805 hp per break.

That's pretty clear, now.

It is also interesting that a 38% increase in current makes the
ground spark seem much brighter.  I wonder if the luminosity of
the spark increases only by 38%, or if it is much higher?

Well, it can't be "significantly" greater.  It is only 38%
greater.  We still don't have a measurement for the potentials to
know whether they are equal or not.

It would seem to me that since the spark appears much brighter
than a 38% increase that some of the potential coming from the
topload to tube might be converted to current between the tube
and ground.
