I was concerned about strikes to the primary from the torrid. I had not though
of corona's forming around the secondary, i a novice at this.  Also i had
considered insulated wireing with a porus spacer. I think this would overcome
some of the problems with dielectric breakdown in the wireing. Heavy wire or
copper tubeing would be used to construct a large flat coil.
