Posted originally in the General Discussion thread, but posted here too for futher discussion: Originally posted by Akito01: If a robot is sentient, then what is the process by which you modify it's behaviour?
By teaching it a lesson! Teaching it acceptance through experience - exactly what happened. My guess is that Bender was hooked up to the port that we saw in "Hell is Other Robots" and "Love and Rocket" and a vision was injected into him. The vision was customized (hence the "everyone experiences the upgrade in a different way" comment) to Bender's personality type and the experience he would learn the best from. Also, that explains the fact that Amy's hair grew back for the next episode in production order. It doesn't explain how "Bend Her" was in 3004 and "Obsoletely Fabulous" was in 3003 (made clear by signs in each). They did it to confuse us!

In "Love & Rocket" Bender were pouring alcohol into an auxilliary tank. Probably for some generator or whatnot. That's probably what we saw leaking out.
In other news: Bender apparently have taught himself how to get up when he's on his back.

Once again an episode where Bender says "Neat!" and take a photo. I've already noticed this in those eps:
1- 308 - That's Lobstertainment During the visit of the town, a plane crashes by the fault of Fox's projectors.
2- 410 - A Leela of Her Own When he meets real Hank Aaron head in the jar.
3- 504 - A Taste of Freedom When the oppressors show the "Mobile Oppression Palace".
4- 505 - Kif gets Knocked up a Notch When Kif gives birth.
And it's always with the same camera! If someone knows others...

Originally posted by canned eggs: Yeah, and the ship runs on dark matter. What was that gasoline doing? Maybe I missed something, but: 1) I thought it was liquid dark matter: Dark matter burns, that's why the PE ship has two furnaces in the engine room. 2) Perhaps gasoline, or some other chemical fuel is used to burn dark matter in the engines? And, 3) Does it seem crazy to anyone else to power an intergalactic starship by combustion? You know, burning? That requires oxygen, from the air; which, on a starship, is in very short supply. Or am I missing the point?

You basically need two things to make combustion: an oxidizing agent and a reducing agent. In modern rockets it's usually liquid oxygene and hydrazine (N2H4) respectively.
The rocket engines doesn't power anything but themselves, though. You need an auxilary power for other systems, so I'm with canned eggs here. The leaking fuel could for example be for a generator or fuel cell that produces electricity for the ship. An obvious choice of fuel would then be methanol since it's dirt-cheap and can be converted into hydrogen with relative ease.

@canned eggs: ethanol is just as cheap as methanol (about $0.40/liter). You're right that they both burn with a clear flame, although various impurities could change the flame colour. If you want a fuel that looks a bit more like the stuff that leaked out of the ship, it could be rape oil. It's being used today as a diesel alternative, because you can use it in diesel engines with only a small modification to the engine. It's also a long chain hydrocarbon so the flames would be more visible than those of ethanol/methanol. It isn't very expensive either, but Hermes is probably just being a bureaucrat. And then again it could just be whale oil.

I wonder if the wooden Bender design was based on the one that they were planning on using in the episode "Fishful of Dollars".

Originally posted by SpaceCase: 3) Does it seem crazy to anyone else to power an intergalactic starship by combustion? You know, burning? That requires oxygen, from the air; which, on a starship, is in very short supply. Or am I missing the point? No, no. In the future, it's incredibly easy to create oxygen out of thin vaccuum. When you see them walking around without helmets, that's because their clothes are generating tons of oxygen (most of which just boils off into space/dissolves into the atmosphere, but enough gets into their respiratory tracts to keep them alive and comfortable). That's also how Bender continues to burn alcohol while floating through space. So, with a super-dense fuel source, plus a nearly-free oxidizer, why not use combustion rather than something tricky like fusion? But who says the combustion is being used to power rocket propulsion? Their coal-style combustion engine is powering some kind of multi-dimensional-physics-based technobabble-engine; the flames coming out the back of the ship are just to vent heat.

Fine. In what episode is this explained, or alluded to? So, with a super-dense fuel source, plus a nearly-free oxidizer, why not use combustion rather than something tricky like fusion? How can I answer this without sounding arrogant, condescending, or giving some boring, 3-hour long college physics lecture... ? 1) Reaction propulsion is inefficient. 1a) Only half the energy goes into pushing the ship. The other half goes into pushing the reaction mass. 1b) According to some NASA study, there isn't enough reaction mass in the universe to push the Space Shuttle to the nearest star in less than a gazillion years. 2) Energy density: Combustion just doesn't produce enough energy per pound to get the job done. Nuclear power shows great promise for interplanetary missions; and antimatter reactors might be used for interstellar missions, though they'd be hideously complex. In a thousand years, they might be using gravity amplifiers. Who knows? But it ain't gonna' be combustion! But who says the combustion is being used to power rocket propulsion? Their coal-style combustion engine is powering some kind of multi-dimensional-physics-based technobabble-engine; the flames coming out the back of the ship are just to vent heat. Possibly: The ship does have a 'gravity pump' and we don't have a clue as to how much energy it needs. Still, combustion seems unlikely. <Scotty> Bu' Capt'n, I Kinna change the laws o'physics! </Scotty>

5acv01, S6E01, "The Wizards Come Clean." How can I answer this without sounding arrogant, condescending, or giving some boring, 3-hour long college physics lecture... ?
Go ahead. I can handle my physics. I even majored in it for a semester or so. 1) Reaction propulsion is inefficient. 1a) Only half the energy goes into pushing the ship. The other half goes into pushing the reaction mass. 1b) According to some NASA study, there isn't enough reaction mass in the universe to push the Space Shuttle to the nearest star in less than a gazillion years. 2) Energy density: Combustion just doesn't produce enough energy per pound to get the job done. Nuclear power shows great promise for interplanetary missions; and antimatter reactors might be used for interstellar missions, though they'd be hideously complex.
But you're missing one important fact: You don't need to push the reaction mass! 1a) Dark matter is orders of magnitude heavier than any ordinary matter, and yet Fry and Bender can (with a little effort) shovel it.* So you're getting, say, 20 million tons of fuel in 20 pounds' worth of inertial mass. Problem solved. 1b) What kind of study could show this? On the other hand, a simple calculation could do it, without the need to get those messy experimental physicists and all their engineers and grad students involved. And this is only close to the truth if you use chemical propulsion. With antimatter annihilation, you only need a few pounds to get to Alpha Centauri in a lifetime (twice as much if you want to stop, four times as much if you want to get back home). With fusion, it takes significantly more, even more with fission, and with chemical reactions you'd have to convert a decent-sized planet to fuel. Still not all the matter in the universe. 2) Combustion of ordinary matter is a definite problem (see the last paragraph to understand why). But if you're getting orders of magnitude more bang for the buck thanks to the odd powers of dark matter, it may be good enough. And burning stuff is a lot less messy than fissioning or fusing stuff. As for nuclear power in space, why bother with controlled fission reactors?** Just set off a big uncontrolled fusion explosion behind you and let it push you forward. It's easy, it's safe, it's relatively cheap, and it means we can do something constructive with that huge arsenal of h-bombs we've built.*** The easiest thing to do (once you're clear of the atmosphere) is set off fusion bombs behind your ship. It's safe, it's easy, and it's relatively cheap. Or build a giant laser in orbit and aim it at a reactive plate on the back of your shuttle, and you can accelerate as much as necessary without any reaction fuel (chemical, nuclear, or antimatter). Although this won't work for the first ship going to Alpha Centauri (unless aliens have been nice enough to build a deceleration laser there for us), it'll work for the second. I know these both sound wacky, but most serious propulsion scientists who don't work for NASA support one or both. <Scotty> Bu' Capt'n, I Kinna change the laws o'physics! </Scotty> What kind of scientist are you? Anything is possible if you believe it is. * This just shifts the explanation to, "How does dark matter pull this off?" but nonetheless, it is a clearly observable attribute of dark matter on Futurama. Here's an explanation for you. Inertial mass is caused by either the gravitational attraction of all other matter in the universe--Mach's Principle--or by an as-yet-undiscovered force--Higgs' Principle. Either way, dark matter, just like all characters dressed all in black, obviously has no principles. Plus, the wizards are scared o' the goofa man. And is this really any sillier than dilithium--especially the way they tried to explain it in the novelizations? ** The answer is mainly "because the bigwigs in charge of NASA's funding are busy golfing with the bigwigs in the nuclear power industry," and partly, "because the geeks at NASA are playing Half-Life with the power-plant engineers." *** I'm not saying that keeping them aimed at Russia just in case they become Communist again, rebuild their army overnight, convince most of the Warsaw Pact to rejoin, and invade Germany with overwhelming force isn't a constructive use....

Well, not entirely, Vintage Dave. Everything I said is not only just barely plausible (assuming dark matter as it's presented on the show, which is incredibly unlikely), and certainly fits with what we do know from the show.
We see Fry and Bender shoveling it into a flame-belching furnace. If this isn't combustion, what is it? And we see flames coming out the back of the ship, which certainly looks like rocket propulsion. So, this is chemical-propelled rocket propulsion. And we see Fry and Bender shoveling millions of tons of dark matter as if it weighed (and inertially massed) a few dozen pounds--which explains why it's efficient enough to work. (Raising the speed of light helps, too.)
I can't imagine anything more plausible that this fitting with what we know from the show. That doesn't mean that I think the writers have thought out exactly the system I suggested. It's more likely that they haven't bothered to think out a completely consistent set of physics and engineering principles before designing the ship. So, the fact that the most plausible explanation is pretty ridiculous is to be expected.
And I'm glad they've done things this way. The pseudo-science-babble explanations of Star Trek are often quite funny, but not in the way we expect from Futurama.
All that being said, I don't think the best avenue for futuristic aerospace research is looking for material that acts like the dark matter on Futurama. Just finish the space station, retool the space shuttle into a vehicle for carrying ships from the station to a little farther out in space, then use h-bombs the rest of the way.
P.S., An ion drive is still a propulsion system. Whether you take advantage of Newton's Third Law with a jet of flame from chemical combustion or a jet of ions from an electrical generator, it's still propulsion.
If you really want an alternative to propulsion, you can look at warp drives, relativistic or quantum wormhole creation or manipulation, exploiting quantum nonlocality (tunneling the whole ship). And you could still have the flames to vent heat, or to give you the little push you need (most of these systems still require a little propulsion, they just let you move through more space than you're actually paying for), or just to look cool.
For a real fun future technology, increase the friction coefficient of the interstellar vaccuum and use wheels to drive to the stars!

Whoa, man! I didn't bargain on 35 lines of closely-worded defense/rebuttal. It can read as humor: smart, dense humor that dances on the edge between plausible and not. Especially when delivered with a straight face - that's the best way to get 'em Oh oh, now you've got me paranoid. Checking my mouth for hooks, Vintage Dave
