I just read a 2002 paper , Engineering the Zero-Point Field and Polarizable Vacuum for Interstellar Flight by Puthoff, http://www.gravitycontrol.org/pdf/jbisZPE.pdf and think there is a loophole regarding propellantless propulsion where his statement that the center of mass must remain constant can be broken by use of a secondary mass contained inside the primary mass but with a different temporal co-ordinate - inertial frame. That is to say that you can move your spaceship with vacuum engineering of gas molecules along an axial coil made of changing Casimir geometry. For whatever reason molecular gas opposes changes in energy density brought about by changes in nano geometry while atomic gas does not. This property allows us to use the gas molecules like "etheric" oars in one direction while repositioning the oars for another pull by either removing the suppression or disassociating the molecule to unbalance the inertial reaction. I am not creating something that "thrusts" against space time but rather am varying the inertia of the gas in alternate directions. This creates a needed displacement where the nano geometry center of mass resides at X,Y,Z,T while the gas center of mass resides at X,Y,Z,t' . The gas molecules oppose change in energy density and must be forced through the changing geometry while being kept cryogenically cooled to prevent disassociation - essentially the tail is wagging the dog instead of employing the chaotic nature of flux on gas in suppression to produce energy we want to use energy to drive the suppressed molecular gas to interact more strongly with the flux/ temporarily changing the inertial properties of the gas in one direction.
IMHO the Rossi, Mills, Arrata energy anomalies are all INITIALLY based on ashless chemistry where changes in this nano geometry are enough to disassociate heated gas that is kept near the threshold point by extracting thermal energy in a carefully balanced reaction. The initial heating doesn't effect the balance because the oscillation between h1<>h2 is endless and only limited by the migration speed of the gas relative to changes in geometry inside the cavity. Propulsion however requires keeping h2 from disassociating while driving the gas through suppressed geometry in one direction while returning it in the opposite direction without suppression. Two axial supression coils on the length of the outer hull of your spaceship with a common return in the center would negate any rotational forces. Regards Fran
