I thought the Plasma Ignition system was worth some investigation (Thanks, Dennis):

Being a trade name for electronic ignition, it's not quite the system i thought it was though:

It seems like only yesterday that i was reading about lasers improving combustion performance. Expect a revolution in diesel engine power-to-mass when this becomes widespread.
Expect various exhaust heat recapture devices to hit the market at some point too:

This one works by reusing the exhaust heat to convert a fuel/water emulsion into a hydrogen/oxygen rich fuel. Pity it is tainted by the "free energy" garbage, as it is actually a sound concept. The exhaust heat energy just goes into overcoming the H2O chemical bonds - no mystical effect there.
