This coil does not exist. It violates the "Freau Equation" for power vs. spark distance. See the archives on John's excellent work regarding this matter.

I told the guy 80 - 300 inches was more like it and asked if he had
ever run the device..... here was his response:

"Hi, my misunderstood what my boss told me, the device lighted the
flourescents in the building 300 feet away, the bolts went up an
average of 30 feet with some he thought topping that as they went
higher than the top of a commercial tiltup building and then some. A
police Helicopter was atracted by the display, he reported seeing it
several miles away. The device draws 50 amps single phase at 220v. The
coil was specially made and had extensive work and tuning done. I have
not personally seen the device work as the last time it was used it
damaged a lot of sensitive electronics within the building including
the burglar alarm. We have far too many sensitive things inside our
building to risk playing with something that produces strong EMP
fields. Aparently a DOD sat did note the device the last time it was
turned on, that was confirmed by the guy who built the device who
called someone he knew."

All I can say is someone is going to be mighty disappointed..

I want to know more about using an internal primary. It seems like it would
be over coupled but, I have no idea really. How is the coupling figured out
with an internal primary?

Operating at 6 kW (220 X 30 Amps) you would be luck to get 80"
discharges. I remember a guy who was running a 38 kW coil and getting
55' - 105' arcs. The coil was 5' in diameter, had an internal primary
and stood about 25' tall.
