Skewon Propellantless Propulsion Spacecraft?

OK Skewon Field has w = -1/3 so it is not as good as ZPF which has w = -1.
Skewon Field DOES NOT WARP SPACE-TIME! It's gravity neutral so it is NO GOOD for WWD, but it still may be good for non-geodesic Corum EM stress-propulsion pulling g-force.

An anti-symmetric stress-energy source tensor permits propellantless propulsion I seem to recall. This may related to Jim Corum's idea. However, remember there are two kinds of propellentless propulsion:
1. Geodesic (e.g. Paul Hill's "acceleration field", G. Trimble's "G-engine")
i.e. Weightless Warp Drive WWD) pulling no g-force in sharp-turn maneuvers.
Here M drops out of the problem. M = mass of ship.
2. Non-geodesic, i.e. pulling g-force like James Woodward's scheme, Shipov's scheme, & Puthoff's scheme.
i.e. VdM/dt term without actual ejection of propellant.
I suspect a hypothetical skewon field engine will still be non-geodesic with g-force and not WWD.
WWD is what we want of course.

Hehl is a serious theorist. Thanks for the tip.

"The skewon field contributes non-trivially to the electromagnetic energy. In particular, it induces an asymmetric electromagnetic energy-momentum tensor, which can cause specific gravitational effects in the Einstein-Cartan-Maxwell system (with skewon)."
