If you go beyond this and start talking about using the intake
air itself to cool the rotors and rotor housings, the achievable 
overall efficiency of the rotary configuration in fact considerably 
exceeds that which can be realized in a piston engine, a fact which 
the Moeller rotary has already demonstrated.

I think what Zachary is saying here is you trade off a little breathing
ability for better overall thermal efficiency. The waste cooling heat is
ingested into the combustion chamber and comes out the e-shaft in the
form of
usable power. This waste heat would otherwise go into the oil and
coolant and be lost forever as usable power. Global warming... for all
you Greens. :-)

The drawing From Mr. Ansdale's book illustrates this quite well.

This is sort of like a turbo compound engine recovering waste heat
in the exhaust.
