Lowest voltage where spark occur?

[Neo-X]

Hi to all overunity builders. I was thinking to build a low power, low voltage teslacoil (cause im afraid of high voltage) using voltage multiplier circuit thus eliminating bulky transformer but i dont know what is the minimum voltage where spark occurs? Sorry for my bad english im not really native english speaking.

The lowest voltage at which a spark occurs depends, among other things, on the width if the spark gap. You could probably get a spark at 50 volts or lower with a very small gap.

Thanks for reply.. I tried 220volt from the mains and when i put the terminal as close as posible it didnt get a spark. So that means spark occur more than 220volts.

1000volt is a lethal.. Maybe i should use a gas which has lower dielectric breakdown so i can use the 220volts from mains.
