RT: I think Joss Whedon deliberately skipped the scientific techno-babble for one or more reasons.

[li]Continuity: By leaving out the techo-jargon, he can’t be pinned down or limited in later scripts by techno-purists.[/li][li]Artistic: he’s setting up the premise that the stuff just works; that it’s a “lived-in” universe and is taken for granted. What Lucas did for Star Wars. This allows the script focus to be on people almost exclusively.[/li][li]Money: He may not have had time (time=money) to concentrate on techy aspects, devoting his writing efforts in getting us hooked on the people, who are (usually) more interesting than machinery.[/li][/ol]
For instance, in Out of Gas, even though the engine is dead and life support is out, the ship still has power and gravity. Of course, a battery system is not implausible at all, or possibly a small auxiliary generator.
This leads to the possible conclusion that the artificial gravity is either a very low-powered system, or an ever present passive system which requires no power (this is lame, but think of the deck being made of an alloy of steel and a high-tech metal called Gravitium 256).
Me personally, I vote for “Artistic.” By leaving the techno-babble out of the series completely (well, almost completely), you resist the Star Trekkian impulse to lame together a script about the alien nannites infecting your computer core or establishing an inter-dimensional “beachead” in the middle of your warp core.
Out of Gas bears only a superficial resemblance to these techno-maguffins; it is clearly evident the story is about Mal’s love for his ship and crew, how they came together, and their care for each other. Plus, the ending was priceless.
Plus, there are instances where Kaylee says they need some (insert techno-talk) and Mal cuts her short and says, “Put that in Captain-speak.” By deliberately and kind of brusquely shifting the focus away from techno-talk the series can stay people-oriented.
I have watched only a very few episodes of Buffy, and none of Angel, but I have heard fans complain of later seasons being kind of lame; in all fairness, they usually point out that in those seasons, Joss Whedon has usually turned almost all the writing over to other people.
Maybe it’s a good thing, Firefly being a short-lived series; maybe now it can forever reside in our hearts and minds as the mythic, near-perfect TV show.
Instead of us, in several years, complaining here that, “Firefly used to be great, now it just sucks.”
