Spark gaps make use of the very low impedance of an arc once the arc is established.

Floyd Sweet referred to rapidly changing impedence in his "Nothing is Something" article.

(side note: is the disharge of a capacitor analogous to BEMF?) (edit - I mean the tempic field aspect)

Grumpy,

I did your circuit in the simulator linked here.  (Copy and paste the text file contents below into the import window of the simulator.)

Interesting results.  Thank you.

did you rectify it? to create pulses only - half wave is sufficient
