Moller International (OTCBB:MLER) has successfully tested its Rotapower(R) rotary engine using a fuel composed of 70% ethanol and 30% water. The Rotapower engine is a key component in the future deployment of the Company’s volantor aircraft including the M200E and M200G models (see www.moller.com), anticipated to enter the market in 2008.

This fuel mixture had a number of remarkable advantages when used as a volantor fuel including:

– Reduced fire hazard since it is nearly incombustible outside the engine.

– Reduced emissions to well below the Super Ultra Low Emissions Vehicle (SULEV) standard set by the California Air Resources Board.

– Improved fuel consumption through the use of a higher compression ratio possible with the fuel’s high octane rating.

– Significantly increased engine power through the fuel’s cooling effect on the incoming fuel/air charge.

The Rotapower engine in the volantor and other applications is able to achieve nearly emissions-free performance while producing nearly two horsepower for every pound of engine weight. Only a turbine engine can match this power to weight ratio, but at a cost that is over twenty times higher ($25 per horsepower versus $500+ per horsepower for this engine power range).

An engine with a high power to weight ratio and low cost is a requirement for the volantor-type aircraft in development by the Company.
