sorry steve i almost edited your post by mistake ...

Yes the outer conductor (electrode) is not connected to the coil and there is also a plastic tape insulation maybe 1 or to maximum turns of tape and one turn at each layer of coil... the coil is connected to the inner tube anyhow... internally... i didn't connected to the outer electrode just for measuring purpose but should be connected in function...
if you make the equivalent circuit than its exactly the vic matrix impedance circuit!!!
It ends up that the coil is inside the capacitor and thus it forms a resonant tank and the electric fields of such capacitor are acting directly at the polarization in the coil...in macroscopic manner..
In theory if this work than its exactly what meyer talks about all the time! Restricting amps to allow voltage do work in a dead short condition. If the amps are not allowed to flow no power is consumed of course.
I mean maybe meyer was trying to improve the tay he han patent idea or working in parallel in the same concepts!!! very strange !!! anyway is hard to say nowadays...
But if that is so than there can be some sort of pulsing style that is possible to benefit if its applied at the resonant frequency of the circuit!
If amps are restricted the electric fields applied to the water can be really high.
Pulsing at the resonant frequency makes sense since the capacitance part of the circuit gets charged first and the coils get charged with some current during charge times, and then the capacitor must discharge thru the coil after in parallel and as such the coil reverts polarity wow strange lot of stuff.
The idea is that the high voltage pass thru 90ยบ ahead of current like stan constantly speaks about...
I think the coil will save the insulation from suffering high stress somehow....
