Could anyone recommend a primer on designing plasma ignition, i.e. very=20 high energy spark ignition systems? My idea is to seriously improve the=20 tired old ignition system on a 2-cylinder 4-stroke motorcycle, and I'd=20 like to experimentally create the fiercest spark that's reasonably possible= .. I notice that a few plasma ignition experimenters appear to be chasing=20 after running traditional IC engines on water, given that plasma=20 sparkplugs do make a heck of a crack when you squirt water vapour past=20 them. Not me in this case, I'm still entirely petrol/gasoline based here=20 for now.
