Paul, Terry, Ralph, Randy, All
Thanks for bringing the discussion of this issue back OT in such a rational
manner. Since the spiral and the helix are topologically equivalent, the
equation transformations should be doable. If this were only 30 years ago, I
could probably recall exactly how. ;-)))

You do have a good point there. I was just thinking the other day
that we hadn't seen any crank stuff on here for ages, and I 
confidently recommended www.pupman-dot-com to someone who wrote me with
some newbie questions that I couldn't answer too well.  I think that
to stiffen the moderation, Terry would have to spend rather longer at
his screen than he already must do to attain the existing standards.
Having considered what would be involved, I think I was a bit though-
less in asking Terry to do even more.

Well I'm sure we can.  Just a slight mod to the tssp software will
do.  There's nothing special about a flat coil - it can be obtained
from a solenoid by a continuous deformation with no changes in
symmetry.  Proximity of the primary could be a real problem, I'd
expect to see a lot of wasteful and damaging corona around the
secondary.

Me neither.  I did model a flat spiral coupling transformer for
impedance matching, but the huge amount of mutual C coupling between
primary and secondary made the thing unsuitable for what I wanted.

Terry, I'll bet an evening with E-Tesla6's code will give you an
E-Tesla7 that will do flat spiral secondaries.  No big deal.  No
new physics.  I still recommend shrinking your Gaussian sphere down
to a conformal cylinder, or in this case, a pancake.  You'll get the
same answers but with simpler and quicker code.

Hardly surprising, if what you call a longitudinal wave is what
everyone else calls a displacement current.  You won't get a 'wave'
because the displacement current 'field' can't have any turning
points - the maxima and minima must be on the boundaries.

I'll calculate it, if you're prepared to measure it as a check on the
program!

You mean a dipole source, surely.  I've never seen a point source 
of alternating charge - conservation of charge prevents it. The
flat spiral secondary will look just like a solenoid at a distance, ie
a very weak dipole source.

> this thread has caused a fun "stir"

Yes, shame really.  A few weeks back someone posted their results
on a mammoth piece of work on SSTCs - a thorough writeup on some
excellent work - surely months of meticulous effort, and the guy got
hardly a response at all.  If I were to post up a mere paragraph on my
highly successful experiments on the anti-grav properties of bipolars,
we would have loads of encouraging and applauding responses!

> See,, it's good for something!!! :o)))

Well if it makes folk like me think about the effort you put into this
list, then it's done some good.  And if it makes folk consider whether
they know what they're talking about before hitting the send key, then
even better.

Cheers All.
