So Jim means frame invariant rest mass m by "inertia" in the quote below. He does not mean the global geodesic pattern solution of Einstein's GR field equations in matter
Guv + (8piG(index of refraction)^4/c^4)Tuv = 0.
Now Jim claims a bare mass cosmological screening.
m is from Higgs field, + Quantum Chromodynamica + Low Energy Nuclear + Atomic + Molecular + Solid State Physics.
Jim claims
m* = m(Cosmological Screening Factor) = mC
C =/= c = speed of light in vacuum.
and his Mach Effect Thruster claims to control C.
Personally I think, MY BIAS, this is astrology and that his effect in the lab is simply bad measurement. However, I may be wrong, and since I am writing my own book and my review of his book will be the in it - I continue.
We now know that Einstein was naive about the Origin of Inertia, Mach even more so. We have come a long way since those pre-quantum theory days.
The Origin of Inertia is
1) Higgs vacuum coherent Glauber state field post-inflation
2) SU(3) strong force Quantum Chromodynamics & it's low energy tail - Nuclear Physics
3) Atomic, Molecular, Solid State Many Body Problem - models of binding energies on different scales.
Inertia m is a FREE PARAMETER in Einstein's GR which is a local gauge theory of the T4 group.
The origin of inertia needs the U1, SU2 & SU3 internal groups + Higgs-Goldstone-Anderson "More is different" emergence of order in the spontaneous breakdown of symmetries in the ground states of complex many particle systems both real and virtual.

Jack Sarfatti There is no way to change the internal energies by a large fraction without destroying the material!

I fundamentally disagree with Jim Woodward .The inertia of the starship has nothing to do with real warp drive or the construction of a benign wormhole star gate time travel machine.
