Neither of these innovations are new. Rotary engines will run on anything combustible. Propane conversions for the 12B motor run about $125 (Propane tanks, valves, and fittings.) Because of the simple nature of the rotary, it's been a strong favorite for the Russian KGB and military for over 40 years. The engine is literally, a pump, but instead of the transmission turning an impeller, the impeller turns the transmission.
Electrically assisted turbos were first made by Aura for use on generators. When I say generator, I mean building sized ones that need to spin up ASAP. A hospital generator must be at 3500 rpm (producing 65 Hz pulses at 440) within seconds of starting.
What the Rotary lacks in it's nature is the ability to put down more torque than hp. That's where I seriously believe Honda needs to come in and integrate IMA with a rotary. The electric motor has by it's own design, more torque than horsepower. If IMA were used as a "torque enhancer" only for a rotary to take over at high RPMs then you could make IMA behave like a supercharger... only a Supercharger straight to the wheels. That would be cool.
