FFF,

The proposed electronic ignition system I am talking about comes with a secondary 25 (or so) Amp alternator that fits on the back of the engine. This gives you two alternators and a battery.

This solution is a lot more practical for existing airframes than re-engining with diesels. The PRISM system is expected to be certificated early next year. The price may be somewhere between 5 and 10K$, a diesel engine would probably be 50 to 70K$ (300 hp turbocharged class).

Also, over here, MOGAS is about 40 % cheaper than AVGAS.

In the long run it will be diesels ... :p

Hmm, seems this is a far more complex issue than I'd imagined. Thanks for your input, guys!
