Re: 3 phase resonators

Hi Thor,

	Very impressive three coil system!!

I think the reason you see the frequency difference between the in and out
of phase situations is due to the space charge capacitance around the
coils.  When they are in phase, there is equal potential between the coils.
 There is not much energy storage in that space since, in effect, the
voltage across that space capacitance is zero.  When they are out of phase,
there is significant energy storage and, in effect, that adds secondary
capacitance to the system lowering the frequency.

	I would think as a streamer is formed and the voltage of the individual
coils starts to kick around, that the capacitance and Fo frequency of each
coil would be unstable and the system would have problems resonating at the
constantly varying Fo frequency.  Perhaps this is contributing to the
problem of getting all the coils to run smoothly at the same time.  Making
the system less sensitive to terminal capacitance and the effects of the
other coils would help this but I have no idea how to actually do that.
Perhaps some kind of grounded or floating "shield" between the majority of
the coils would help but that would just introduce a strike target unless
one were very tricky in placing it.  Perhaps a cage around the coil to add
capacitance outside of the triangle of coils and around the top would add
stabilizing capacitance to the system...

Cheers,

	Terry
