You are right, Jesse - no conflict here. If both a
reciprocating engine ( which is normally a iron block(or steel sleeve
inserts) with an aluminum piston) and a rotary loose coolant, my bet is the iron
block will at some point seize from overheating. Because the aluminum
piston will expand faster than the iron/steel due to the heat. Just the
opposite with a rotary (as at least two/three folks have proven), the aluminum
housing expands (and some compression/power is lost) faster than the iron rotor
- so no seizing even though the engine is cooked.
Never said you wouldn't damage a rotary with a loss of
coolant, just that it would keep running as long as then engine had fire
and fuel. Landing with a damaged engine with some power available beats
dead sticking in a seized engine in my opinion.

NPG for Rotary Engine use
Now wait a minute there Ed. I thought that was
supposed to be one of the rotary good points, not as likely for seizure
when/if coolant loss, etc..

other engines (like the
Subaru) that can stand higher metal temperatures, NPG would seem more
attractive.
