just my guess, I think this may be the next green car engine.
Also fits the description that the Navy was looking for, mulit fuel, and 2/3 lighter. The 42 HP size is only 6 inches by 6 inches,
and the military is already looking a it.
Could be the one AFTC will be designing high pressure fuel system for?
And it would explain why S Korea and the car mnf in Europe is taking so long to get a finished test vehicle out. Ele/DME hybrid car with this small efficient diesel rotary engine will be far ahead of the old piston type, diesel conversions. JMHO
