When the ship was moving in one direction only we calculate that all of the
missing mass ends up as kinetic energy of the ship. But now that two
directions are used and we end up at the original starting point and velocity
we decide that all of that energy is imparted to the negative energy sea. How
do we reconcile these two very different sinks for the energy?
I seldom like to use the term magic in a scientific argument, but that is the
best way to explain this concept. We operate a device onboard our ship for a
long period of time while our ship vanishes into thin space. We have
absolutely nothing to show for the missing mass and no one can locate any of
it. That is a long stretch.
A second observer that was at rest next to the ship before the drive was active
is also confused. He sees the ship gaining kinetic energy while violating the
conservation of momentum by demonstrating no exhaust stream. But then, it
returns to his side with no motion remaining and contains potentially much less
mass than before. He must be totally baffled. This is especially difficult
for him to understand when everything would add up correctly had the ship used
a normal drive by ejecting exhaust.
There are too many inconsistencies for me to accept the concept as possible so
far.

The guy need only account for the loss of mass energy by adding the amount of
energy transferred to the negative energy sea.
Of course, if he does not consider a negative energy sea exists, he cannot
properly account. He is stuck with an observation that makes no sense to him.
His reaction less drive converted what was originally linear momentum of real
particles to the intrinsic property of angular momentum energy, which he does
not accounted for in measuring the the rest mass of real particles. The rest
mass of his ship has decreased from his counting of particles, the angular
momentum of the universe has been transferred to the negative sea--the Dirac
sea.

Yes, he can determine that he has changed velocity by looking outside the
ship at other objects. That is why I proposed the recent posting where he
returns to the original location and velocity. That procedure counters the
thought that a final velocity change can obscure any problems due to usage of
the reactionless drive. Special Relativity is generally considered capable
of countering the natural feeling that a particular velocity is important in
space, but with zero velocity change there is no need to play that card.
The guy must reconcile where the mass of his ship has gone after using the
reactionless drive.

You stated:
<<<After the drive is shut down the ship stops accelerating and comes to rest
in space. Even though the new velocity is different than the old one before
the drive operates, a guy onboard the ship can not determine that he is
moving. >>>
Yes he can determine he is moving. All he needs to do is look out the window
and see that he is moving relative to objects that were fixed before he
started his travel and are assumed to have remained fixed.

The fact that energy can be extracted from the battery to drive the
microwave source is certainly possible. No one will ague against that
point. The problem is that this energy can be depleted without having
anything to show for its loss. If taken to the extreme most of the ship
can be converted into energy by some nuclear process to supply power for
the drive mechanism.
After the drive is shut down the ship stops accelerating and comes to rest
in space. Even though the new velocity is different than the old one
before the drive operates, a guy onboard the ship can not determine that he
is moving. He will not have any kinetic energy relative to himself. He
sees that his ships mass has depleted but has nothing to show where it
went. With a normal drive the guy can see the exhaust that is moving
relative to him which contains all of the converted energy.

One thought here -- the "reactionless drive" that I am aware of being in
the recent news is the EmDrive. That one involves the generation of
microwaves and their reflection in a cavity. It's not clear whether anyone
other than Nasa and the inventor believe that it works as advertised. But
if it does, note that energy must be expended to generate the microwaves,
e.g., by a battery, to which the usual E=mc^2 conversion will apply.
