Dropped a decimal -- should be 5.08e7... thanks for catching that. That
means the drive will only be 13,000,000% efficient. Oh well.

from my post:
>The problem is that the MT manuver drives are not rockets!

I was referring to Megatraveller. Check the Ref's Manual p.56:

"This new, artificially generated force pushes against a vessel's
`thrust plates' themselves, which make true reactionless thrusters
a reality for starship-sized vessels."

Not until MT was the power consumption of the manuver drive given
(High Guard had power plant energy point figures, but that was in
addition to powering the drives.)  There was never anything in the
old set that said the manuver drives were rockets, either. Everyone
I ever discussed it with assumed they were rockets, as did I, since
that was the obvious explanation for the high fuel consumption.  I don't
know what Marc Miller and co. intended them to be at that time. Metlay?
My guess is that they were intended to be reactionless all along, otherwise
why switch?

This would cause BIG problems for warship design, since the limiting factor
for many designs is power for weapons, and this would make it 1000 times
easier to get.....  It would probably work better to reduce the fuel needed
for the power plant, while keeping the output the same.
