BTW Paul Moller is not pushing the envelope on rotary engines.
Abel Ibbara in Riverside CA IS pushing the envelope on
rotary engines getting 800 HP out of a 250 pound
turbo Mazda RX7 two rotor at 10,000 RPM.

A rotary engine, of the size Moller is building, could probably run at
15,000 RPM. If he built a small planetary reduction gear
box to keep the ducted fan speed reasonable he could, if he solved 
the cooling problems, get as much as twice the HP.
