My thoughts on this is that if you have a region equaly distant from both
coils, but offset from the center line, the electric field vector their will
be a rotating at the sum and difference frequencies, causing ions to swirl
in the vortex.
The ion-cyclotron resonance of ionized air, in the Earth-ambient 1 Gauss
field, will be in the frequency difference range of the TC's. The excited
ions will absorb energy at their resonance (pressure-temperature-density and
energy will match the frequency) and not kink or pinch as in typical
filamentary discharges, but be diffuse and spherical in the diverging
electric field.

My understanding is that if you have enough energy, (since E=MC^2, energy
and mass are equivalent) space and time itself will warp, until it finaly
tears when it gets sucked down into a singularity, A.K.A 'black hole'. This,
I understand, requires a non-trivial energy source.

An interesting article on microwave oven ball lightning is:
"Experimental Investigation of Large Volume PIA Plasmas at Atmospheric
Pressure" by Brandenburg and Kline in vol26, 4/98 IEEE Transactions on
Plasma Science.
It describes how to put a spark plug in a microwave oven, which then
initiates a diffuse vortex discharge which persists with the right gas flow
rate.
Add a little CO2, and you could turn your microwave into a kewl CO2 laser :-)
BTW, what's the address of the laser list? Is anyone on it?
