12 volt generation of a sustained arc

chuck85210

I need help finding a device that can generate a sustained arc while utilizing only a 12 volt power source. Does anyone have any ideas? Arc should be able to jump a 1 and a half inch gap.
Also what materials should I use for the electrodes that would not degrade over time?

Ranger Mike

it takes 25000 volts to jump and air gap of 0.025 inch...with 12 volts...good luck with that 1.5 inch gap

how is that posible when a 60,000 volt stun gun can create an arc of 1 inch with a 9volt battery?
thanks for your input

I was going to suggest just that. Will it work for you? What in the world is your application?

chuck85210

application is ozone generater but I need an array of probably 8 arcs for the amount of ozone needed

also its an automotive application

it seems you are correct as I checked into tyhe stun guns and the ones capable of creating an arc that I am looking for requires 4.5 million volts. at 60.00 a piece I think they will work nicely

dr dodge

any air gap spark discharge can disrupt local communications based upon the frequency
be careful that the FCC does not get mad at you
those guys in black suburbans have very little sense of humor,
(trust me on this one)

will keep that in mind

just purchased 5 4.5 million volt stun guns for 35.00 each I'll use an ozone detector to see if I'm in the ballpark

I don't believe you need an arc to generate ozone, just an intense electric field. Passing air through an air dielectric capacitor charged to a high voltage should do the trick without creating an arc.

the arc also creates other compounds that are desireable for my application

For the people reading who aren't familliar with ozone generation:

In particular, breathing it causes permanent damage to lungs.

Good info! Especially this:

So Chuck, how much experience do you have in working with hazardous materials?

chuck85210

wow!!! thanks for the info but it is an effect I was counting on I will do further research before proceeding. combustion is part of the experiment and I will take extra precautions with ventilation. You are a wealth of information and I appreciate and take it under advisement.

dr dodge

additionally, ozone degrades any rubber, and speeds up the dry rot process
so...metal lines would be safer if pumping this
not sure about plastic

thanks for the info I am taking all advice into consideration you guys are saving me alot of time and money experimenting
