Scifi and realism

[Eldan]

"Your calculations indicate that powering a non-ship thing will require diverting roughly 27.3% of total reactor capacity for a little less than 8 minutes"

But surely, you'd want some kind of basis for those numbers.

"All the rebels have exhausted the power packs in their laser rifles! For how long can we keep those lasers going with the fuel in our spaceship reactor?"

That's a question that might come up. And, well, you probably want a rough idea, at least.
