Hi Wayne. Plasma Jet Ignition has been around for 40+ years far as I know. Developed for jet engines and industrial apps I think.
All ignition sparks technically are plasma.
Would take me a while to try to explain this, better if you google it. Google these terms:
Ignition Secrets by Aaron Murakami | Plasma Ignition
Blue Phoenix Ignitions
Mad Hornet Ignition
Blue Phoenix and Mad Hornet sell systems to do this. I recommend buying Aaron Murakami's Ignition Secrets download pkg.its $37 I think. That is for the DIY'er. Most of info around is from benchtop builds, demo's, etc.
Once you get the download, study it and try to understand what Aaron and Peter Lindemann
are doing. They have a lot of videos to explain it and break it down. There is also a support thread for this at Energetic Forum.
I've decided to not completely reveal the exact secret cause I think Aaron deserves credit for figuring out the "trick" here, his $37 download is worth every cent IMHO.
I learned far more DIY ing it than if I had just bought a pre made system. I dit it as a "layered" build. I would still have a kick-butt ignition even without the Plasma. Very robust bad-boy parts needed to get Plasma, each contributing to final result, like non resistor plugs and plug wires. A Capacitive Discharge Ignition box is recommended too, like MSD, etc. But there are a few Tricks involved, Aaron is very clever to have figured it out, it involves a shortcut.
In other words, ya gotta DIG for this one. Its Worth it! Get Aaron's download. I WILL help anybody who does that. It's a bit like the Groove, I'm not going to encourage tool makers to copy Ron's bits for example, but I do help Gadgetfolks. We all regret how TPTB treated Tesla, right? See my Point?
