Does it run on Windows?
In terms of AVGAS engines, effort would be better spent on making a magneto that was more "solid state" with fewer moving parts, that still generated its own charge and used very little electronics to time the collapse of the field. Lets face it guys once your trained and familiar three levers ain't that hard to do.
As for this piston diesel that you guys keep raving about. It will never happen, with the advent of nanotechnology and advanced manufacturing the micro turbine will become the standard. Its bad enough swinging four and six pistons of the size and mass in an aircraft engine at a compression ratio of say 9.0 to 1 on average. Now try and do that at 22 to 1 and manage the harmonics/forces/vibration. Why bother when a micro turbine is smooth as silk, will be thermodynamically efficient, more reliable etc etc etc.
