Coil on plug ignitions are commonplace now. I have it on two vehicles. I wouldn't be surprised if there are more new cars with this type of ignition than without it.
I don't know of anyone adapting a CoP ignition to an engine originally designed without it. Especially with the rotary's odd plug arrangement. Not to say it is impossible, though. Just a matter of finding parts that fit and will light the mixture.

Thanks Bill...........Are you aware of any other cycle or auto "COP" units that may be out there that can also be
checked out for possible rotary use ??.............

Kelly, I found these photos of the coils you can get an idea of what they look like. Bill

Bill,
Would you happen to have a photo of the "Coil On Plug" of your Yamaha ??...............Interested in how they
are secured to the sparkplug...............

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.
