Which raises the question:
What defines a Tesla Coil?
Commonly: an air core, resonant, RF transformer based
system.
Tesla Experimented with 'iron' core coils...
Modern workers routinely use non spark gap drivers
and have experimented with VHF frequencies.
I have proposed that the classic (now obsolete)
gas engine ignition system is a form of
Tesla Coil, with a steel core. I admit to
not checking for resonance.... 8)>>
