1. Obeys physics Rocket Equation 

2.  Pressure Thrust based propulsion,  not traditional Momentum Thrust

3.  Passes low velocity choking two-phase fluid     (<50 ft/sec [15 m/s]) through non-expanding rocket nozzles, for the highest possible Pressure Thrust-to-Momentum Thrust ratio

4.  Recycles fluid while zeroing out Momentum Thrust, thus conserving Newton's 3rd law

5.  No mass leaves the control volume

​6.  Potential disruptive propulsion efficiency for aircraft, launch vehicles, and spacecraft
