Suppose, as has been claimed, the drive is somehow exchanging
momentum with the entire universe. The momentum of the universe may
have a (?local) velocity - which would be mathematically equivalent
to a preferred frame of reference.
If so, there need be no violation of either of the conservation laws.
Even that wouldn't be of any practical use for propulsion.
There's basically zero chance that you would moving close the preferred
frame of reference's speed. And if you're not.. .big trouble in little
china.
To see this, consider that we're already going at (say) >300km/s due to
orbital speed, the speed of the Sun within the local cluster and the
orbital speed around the Milky Way, and the speed of the Milky Way
relative to other galaxies...
According to the cosmic background dipole, "369±0.9 km/s relative to the
reference frame of the CMB (also called the CMB rest frame, or the frame
of reference in which there is no motion through the CMB) in the
direction of galactic longitude l = 263.99±0.14°, b = 48.26±0.03°"
wikipedia, "Cosmic microwave background", "CMBR dipole anisotropy"

BTW, it continues:
"From a theoretical point of view, the existence of a CMB rest frame
breaks Lorentz invariance even in empty space far away from any galaxy."
so it takes enormous energy to make quite
modest increases in speed because energy goes as 0.5 m V^2.
Indeed - but it depends on which direction you want to accelerate in.
But none of this really matters, it's all bullshit, there's no such
device, and there's very, very, very good theoretical reasons for
thinking no such device can be built,
And what are those? I don't know of any.
I don't believe the drive exists - but I don't know of any theoretical
reasons why it would be impossible.
and that the current results are
experimental error, and that even if you could, that you couldn't use it
for propulsion.
I agree about the results - and as I have said, I don't believe in the
drive - but I'm not quite so sure about not using it for propulsion,
especially if you weren't in a hurry.
