Spark length at 20x mix

[benstern]

What would be the maximum spark length of a 900,000 volt stungun be under the conditions of a 20x mix? (291 psi)

Are you hinting something here, like you are going for 20x. That would be like a 2000 PSI combustion.

Is this for your secret DOBA launcher?

I scrapped the doba cannon for this project. (this is louder, cheaper, lighter, and more powerful than the doba) And yes, I am going for around 2000-2500 psi. The chamber and burst disk would easily be able to take that.

Holly shit.... You sir are going to die.

Um, you'd have to do some test. A 900,000 volt stun gun is NOT 900,000 volts though. 900,000 volts should be able to jump in the range of 75cm in air, and I'm pretty sure it wont be able to do that. A neon light transformer with a 2mm spark gap should do the trick though if you have wall electricity avalible.

You stealin' my idea for a 20x hybrid benny?

I see an explosion comming!

Geez!- I see that nothing has changed, as far as hairbrained ideas are concerned.

Does anyone even consider the fact that "if" a propane/air mixure were compressed to 20 atm, that it would autoignite? - There would be no need for a spark.

I see a darwin comming.

It depends on how fast and HOW it is compressed DR. If it was filled out of a HPA tank, it would be cooled, due to expansive cooling.
