> MOLLER INTERNATIONAL ACHIEVES BREAKTHROUGH IN ROTARY ENGINE
 > PERFORMANCEDavis, CA, May 14, 2008 Moller International (OTC-
 > BB: MLER) announced today that it has
 > achieved a major breakthrough in rotary engine performance. A
 > version of the Company's
 > Rotapower® engine is designed in such a way that the engine
 > two rotors operate in series rather
 > than parallel. This design allows the first compressor/expansion
 > rotor to supercharge the second
 > power rotor while the exhaust from the power rotor is further
 > expanded in the
 > compressor/expansion rotor, extracting additional power. In
 > effect, the engine operates in what is
 > termed a compound cycle. Because of the additional energy
 > captured from the exhaust gases,
 > engine noise is reduced by 93% and exhaust temperature is
 > reduced by 47%. Moller
 > International non-compounded Rotapower® rotary engine has
 > already demonstrated a fuel
 > consumption 12% below that of the new Mazda Renesis rotary
 > engine. Compounding is expected
 > reduce the Rotapower® engine fuel consumption by an additional 25%.
 > Rotary engines are particularly small and light relative to
 > their power output and nearly vibrationfree
 > in operation. Compounding makes the Rotapower® engine
 > potentially much better than the
 > piston engine in fuel consumption as well. This was the major
 > limitation that prevented the rotary
 > engine from supplanting all piston engines. It now becomes an
 > attractive candidate for the Plugin
 > Hybrid Electric Vehicle (PHEV) market where weight, space, fuel
 > consumption, emissions and
 > vibration are all critical. The Rotapower® engine previously
 > demonstrated its ability to meet
 > California Super Ultra Low Emissions Vehicle (SULEV) standard
 > without exhaust after treatment.
 > Moller International is in the final phase of negotiations to
 > license worldwide production and
 > marketing rights for its Rotapower® engines to Rotapower Engine
 > Systems, Limited of
 > Southampton, United Kingdom.


93% noise reduction and 47% heat reduction  This is phenomenal!

Nothing really new as Rolls Royse built something similar.
What they are not saying is the weight of the engine will double
and the displacement is half as it becomes a supercharged one rotor.
The HP will go down. The size per HP may be closer due to the
supercharger. The HP per cubic inch of the one rotor would also go up due
to the supercharger. It would be easy to make
a p-port version out of a two rotor Mazda 13B.
