Ok folks the thing is all you need is a SUCCESSFUL spark. It does not matter if the ignition is caused by a electrical spark or laser. The important thing is reliability. The motorcycle industry has been changing to coil-on-plug systems. Remember that many of the sportbikes have redlines over 13,000 rpm. These coil on plug systems can easily handle our rotary needs. Using a programer to control spark it would be easy to trigger them, and you could do a split or same time firing. We don't need bleeding edge tech. We need easy tech. My Yamaha 1000 uses the coil on plug technology. It is a 2008 model. We could harvest this tech for our use. The big advantage is only low-tension switching island needed. Using coil on plug you would have 4 coils on a 2 rotor. A single failure would only kill one plug.

If you've got a film building up on the rotor housing's chrome face, aren't you behind the curve already?  I could see
it being a problem in a piston cylinder's head.  I've had to chip off gunk with a screwdriver it had built up so thick.
 But they aren't constantly being wiped by an apex seal like in a rotary.
