Ok, first things first, read
this article. It's a reasonably articulate, and superficially convincing argument as to why the trash compactor on board the
Death Star, into which Luke, Leia,
et al., ventured to escape imperial guards, is at best implausible and at worst completely absurd. However, being a huge nerd, I have a number of bones to pick with the author's arguments, and I DO recall promising to include a number of posts of a science-fictioney nature. So without further ado:
0) The author explicitly assumes the Death Star ejects all its trash into space, based on an extrapolation of the fact that ISD-class ships (and let us further assume lower-class ships as well) eject
their trash into space, as evidenced when the
Millenium Falcon sneaks out with the trash. This is an invalid extrapolation, for several reasons. First, The sheer size differential between an ISD (Imperial Star Destroyer) and the
Death Star dictates that different trash disposal systems may be entirely necessary. While able to travel through space at will, the
Death Star, as the flagship battle platform of the Empire, may often find itself in extended geostationary orbit about a planet. As
this article indicates, the station requires literally
millions of workers, soldiers, and managers to operate to its full capacity. Millions of active people produce a LOT of waste. Even assuming the station has ample temporary waste storage facilities, it must eventually dispose of that trash in some manner. Ejecting it into space while stationary seems to be an absolutely disasterous approach, as the flotsam and jetsam created by such a process would create havoc among the massive force of accompanying starfighters and support craft. Imagine having to dodge every frozen flying turd while trying to dock!
So what solution apart from long-term storage and ejection is there for proper waste disposal? Keep in mind that the
Death Star is nothing more than a platform for the galaxy's most powerful super weapon, the oh-so-imaginatively-titled
Super-Laser. Apart from the ancillary and support services requiring power on board the station (and providing power for millions of people simultaneously is no simple task!), the laser itself requires an
incredible amount of power. I won't even begin to guess as to the pure wattage required here, but as we know from Return of the Jedi, the reactor core is, in scientific terms,
friggin' huge. So the simple solution is: why not use the waste-heat, or the core itself, to incinerate the trash? Seems simple enough. Of course, delivery to the incinerator requires some sort of transportable form of waste material, hence the compactor: nice, neat blocks of poo, ready for burning!
Now for his specific points, which I paraphrase in each case:
1)
Why have a ventilation system leading to the trash compactor?
Proper one-way airflow and suction could have prevented any "out-go" of effluvia, hence the VENT COVER and the fact that she actually had to BLAST the thing to remove it. The "vent" might have ventilated
out of the hallway rather than
into it -- perhaps an air-purifying vent that trapped and removed impurities from the air, much like the CO2 scrubbers on board our own space facilities.
2)
Why have a two-walled system of trash compaction rather than a single moving wall and a more stable, fixed second wall?
I promised myself that I'd only use this argument once: George Lucas is an idiot-manchild who got very lucky 2 1/2 times (woulda been three except for the ewoks).
3)
Why does the trash compactor move so slowly, and why does a relatively thin metal rod nearly stop its compaction altogether?
The author makes the assumption that this particular trash compactor is
supposed to compact metal and other solid trash. First of all, assuming this is true, I would imagine a slow, steady compaction is more safe and robust than a quick smash -- have you ever seen your own kitchen trash compactor at work? It takes a significant amount of time, and that's only for cardboard and paper products. Moreover, I call this assumption flawed. Two points here: first, while the
DS was a relatively new facility, it WAS complete. How many of you working in fully-built buildings that are NOT production facilities of any sort throw away large pieces of scrap metal on a regular basis? Just because it's made of metal does not mean you'll be toting around and disposing of metal. Thus, it is highly likely this particular compactor may not have been designed to handle metal with any efficiency.
That brings me to my second point: if not designed for metal, why was there metal in the compactor? Well, here the newness of the structure plays into my favor. With millions of employees on board, you would be bound to have more than a few stupid or ignorant workers who are not familiar with the rules and regulations, and would thus attempt to dispose of their garbage improperly. I'm sure those workers were dealt with in the usual Imperial manner, which is to say a laser blast to the back of the head.
4)
Why only compact the trash in one dimension, resulting in large flat pieces of trash to be ejected into space?
See my comment zero. You're not ejecting into space, but rather preparing it for incineration. Additionally, this assumes that the two-wall method was the only part of the compaction process -- perhaps the ceiling would descend at some point, and then the other side walls? We only saw this process because the remaining compaction process was thwarted by our intrepid heroes.
5)
How did the critter living in the compactor survive? I actually like the author's suggestion that the creature living there was actually put there on purpose, to devour organic trash, although I would suggest an alternative. My first point in rebuttal three addresses the presence of inorganic material. Then keep in mind that there are
millions of people on board the Death Star. Those people must be fed. Rather than have to import food constantly, I would suggest that some of the massive space on board may be set aside for the growth of nourishment, perhaps through hydroponic methods. This, of course, requires fertilizer, so it's not a stretch to think that the designers would employ some method of recycling organic material for greater efficiency. Thus, I propose that the creatures is there to serve a purpose similar to our own earthworms: it "churns up" the organic material, aiding in the process of decomposition of organic material. Larger bits get compacted for disposal, but the heavier, decomposed bits fall to the bottom, as suggested by the author, and are collected for reuse in the food production facilities.
This may be a bit of a stretch, however. A simpler solution is as follows: Much like our own alligator-pets, some mid-level commander had an illicit pet one-eyed space eel (or whatever it was) that just got too big for his dinky quarters, so he just happened to have surreptitiously disposed of it after the last compaction cycle, so it was a relative newcomer to the area, just as scared as our aforementioned intrepid heroes (although if they were afraid, I guess they'd be
trepid heroes rather than
intrepid, right?).
6)
Why have separate organic and inorganic waste disposal systems?
See response #3.
7)
Why would an evil empire care about the environment?
I address the notion of trash dumping in my argument zero. Assuming the game
Tie Fighter is canonical (and it was so friggin' awesome that it could be nothing BUT canonical!), we are presented with a much more sympathetic picture of the Empire. Sure, the overlords are evil bastards, but at the end of the day, they are out to control the universe, not destroy it. Even evil dictators can be good, if not "nice", stewards. If they trash up their empire, it's not much to brag about at the annual Convention of Evil Imperial Overlords conference, is it?
8)
The worm-compactor combo is more inefficient than, say, a trash-ship to tote the trash away.
My arguments 0 and 5 rebut this complaint.
9)
Space is so huge. Why bother compacting at all?
How many times must my argument zero counter his arguments? At least this is the last point he makes.
Therefore,
quod erat non demonstrandum. The Empire was not in the business of creating hassles for itself. Ruthless efficiency indeed!
