I wonder if the small generator will have enough power to feed the
low primary inductance of the transformer. Something that surely works
is to rectify the output and charge a capacitor with it, and then
use an SCR to discharge the capacitor over the primary of an ignition
coil, that could then power a small Tesla coil. The SCR can be triggered
when the voltage in the capacitor is high enough, by just connecting
a pair of neon lamps and a resistor, in series, between the anode and
the gate.
