I was watching TMP today and I got to the V'Ger cloud entrance when I heard something that has long nagged at me.
Approaching the cloud, Spock says it is "A twelfth power energy field." Sulu reacts with shock to this by repeating "Twelfth power!". Decker later says "That measures twelfth power energy? Thousands of starships couldn't generate that much-" whilst Kirk says "No vessel could generate a power field of this magnitude."
There is no explanation of what "Twelfth power" means, so it could have pretty much any meaning. Two things stuck out to me - first that they pretty freely intermix the words power and energy. There's nothing new in that, of course, Trek messes it up all the time. And actually it's not that bad a mangling here compared to some. Spock later says that V'Ger is radiating energy greater than the Earth's sun (I think this is cut from the special edition).
The other thing that was that it seemed not to be the "twelfth power" aspect specifically that bothered people, but rather that an object so big could be that. Although not certain, the implication seems to be that whatever scale it is, it's a measure of power/energy per unit area or volume, or perhaps radiated power/energy over a particular solid angle.
I often wonder if there is some sort of Starfleet scale of energy fields. Maybe it's like phaser type numbers... containment fields are 1st power, ship's shields are 5th power, etc? That would work with the idea of size being a factor, since we know that larger shields require more juice to maintain than small ones for a given shield strength.
As with many things Trek, there really isn't anything like enough info to judge, but it had me musing and I thought I would put my musings here.
