OT: Revised Edition Star Trek

[Suicide Junkie]

If they were able to reverse entropy on a closed system like a cloaked ship, they'd have no need for fuel at all...

Also, I don't see any evidence that the "warp core" does anything out of the ordinary...
It just generates gobs of energy via simple matter/antimatter annihilation (with a technobabble reaction mediator).

As far as I can tell, the nacelles do all the FTL work.
The "fact" that the impulse drive and even the computer core use the same type of TB field when running off of simple fusion or emergency battery power is also telling.
