I would like to start by thank every one for there help so far. But there 
are two critical things that I still don't understand.

First of all on Richie Burnett web site, which btw was very help full, he 
talks about notches in the primary and secondary voltages wave forms where 
all of the energy is transferred from one to the other. In my mind it seems 
that as a current is induced in the secondary by the primary it would then 
begin trying to induce a current back in the primary. So that it would be 
losing energy at the same time that it was gaining it. There would still be 
a periodic nature to the transfer because the transfer rates will still be 
dependent on the resonant frequencies. But instead of all of the energy 
flowing from one to the other it would reach a equilibrium where the 
current in the primary was trying to transfer energy to the secondary at 
the same rate that the current in t! he secondary is trying to transfer it 
back. (It is very possible that I simply don't understand the nature of 
problem properly in which case simply tell me it doesn't work that way and 
I will go work through the math and see what happens.)<?xml:namespace 
prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Second I simply don't see how the secondary can behave as a LC circuit in 
that it is grounded at the bottom and it clearly has enough voltage at the 
top to ionize the air and discharge that way. So how is it that it can 
resonate with out extreme damping from the top discharge and the voltage 
simply flowing away in to the earth when the peek voltage flows to the bottom?



Thanks for your time
