Richard,

This is an interesting post.  I have considered ideas regarding
electrostatic waves (little or no magnetic component).  This is all a
bit
theoretical and forces a red blast of livid palor on the dyed in the
wool
electrodynamicist.

It is interesting to note that one of the main mission goals of the
tethered
satellite wire shuttle experiment was to investigate the propigation and
characteristics of "electrostatic waves"  in addition to electromagnetic
waves.  This formal printed statement must have gotten past the NASA
electrodynamic sensors!  Still, the chink is in the armour and lots of
mainliners are doing closet stuff or thinking closeted thoughts along
these
lines.  I am amazed at the number of retiring respected physicists who
are
writing books about the problems in physics and taking positions they
would
dare not have taken out loud when employed or accepting grant money.

I will let this go at that and continue investigating the most
intersting
aspects of the Tesla coil while having a blast just building and
watching
them, too.
