The RDA can't do physics

[Clarke]

It is the Meissner effect, which is different to the normal repulsion between two simple dipole magnets, as I already said.

Yes, but they still drop off at 1/r^3, which means that no magnetic field in the universe could support the mountains.

Earth's varies by as much as 2-3x the strength over different areas.

That's not hard when the difference is so tiny.

I mean that you mistake consistency for possibility in the current day. I would bet Dr Who is consistent, despite not following real physics.

And you'd be wrong. Almsot the entirity of Series Fnarg was poking fun at the complete lack of consistency. At one point, the universe never exists, for instance, and it's the Doctor's job to make it... have existed.

Star Trek is consistent despite following something between realistic and implausible physics, but it always woks the same actual way.

However, the important thing is that the important bits of ST do not rely on actual science, and so it's impossible for the writers to get it wrong. (That particular episode of Voyager involving "cracks in the event horizon" is disliked for mostly that reason, AFAIK.)

Nothing in Avatar contradicts itself...

This is, on its face, true, but compare it to looking at a stage backdrop. From the audience, the set looks believable, but then the director starts offering backstage passes, (read: background material) and when we actually start poking at it, we find that the backdrop is just that: a paper-thin facade to tell a story in front of.

You've been continually complaining about how it is 'not consistent' without even understanding the definition.

I can do formal logic, thank you very much.

Things that are not plausible beforehand have happened throughout human history as understanding has improved, but hat does not make the reality inconsistent.

Which is why I'm continually saying that plausible and consist are not related. Avatar is perfectly plausible (which is perhaps a failure if you want cutting-edge sci-fi) but not actually consistent with the sign it has which reads, "Like reality unless noted."

Trust me, you can't argue canon with me

Where else would it come from? Nuclear fusion is the second most energetic reaction in all of conventional particle physics.

A fusion reactor explicitly allows a higher capacity without the danger of producing a critical mass when not operating. The only known upper limit would be the largest known star - clearly, that is impractical on Earth, but it does not suffer the same limitation as fission.

You'll notice that the fusion reactor template in my plan above is 2-3 times as powerful as DEMO's projections. It needs to be 4-5 times more powerful again for the RDA to require less than 1,000 reactors.

There's no mention, but there's no denial of one. All there is is a mention of how poer is produced on Earth, which is said to produce more energy than people can use.

So, wat, we've solved biology? Particle physics? We've done all the data processing we could possibly need?

Remember that robots will weigh just as much.

O RLY?
...Seriously how on earth coudl you know that?

1. Wrong. you seem to believe unobtainium is the only profit source just because sefridge said that, but that doesn't make it true. there is a lot of genetic research, for example in using plants that absorb metals form the soil in cleaning up contaminated areas on Earth.

Why do you need any of that? You've cracked genetics. (I infer this based on the Avatars being a mix of human and Na'vi DNA, which doesn't make sense unless we've basically made organic chemistry our pet.)

2. If you actually watched the film, you'd know that that is entirely the point, because being seen not to be harming the Na'vi does help their image, even if many people do realise what's really going on. Using robots everywhere would totally destroy that perception and then some.

Again, what's with robot == war machine?

Lasers do not exist in a useful form (weapons on Earth are gauss-type). The RDA can not use those because they do not require advanced military hardware. This is not an invasion, and they are not supposed to be causing any damage.

...So you use a weapon that can also be used to stun?

They're being limited by governments and organisations like the UN here, in that a species of sentient beings deserve equal rights, even if unobtainium is useful. That means the RDA are not going to have advanced military hardware for some kind of invasion like you wanted to see (in which case, there is plenty of fiction for you, don't try and use false logic to rationalise Avatar into something you wanted with spess mehrens killing everything).

So Quaritch gets court-martialled, or...? Because that wasn't even hinted at in the film.

Again, there's no need to do so, because they aren't going for mass slaughter. What they have is enough for their actual needs that they are supposed to be using it for.

You don't want enough; you want the most effective solution.

Actually, it uses He-3 from Polyphemus.

Fusing water would probably be easier.

The presence of energy for hell's gate doesn't mean they will have ridiculous military lazor weapons that aren't even mentioned on Earth.

It makes using them more economical, though.

Again, nobody has ever stated where the actual energy for the ISV comes from.

Earth has too much power to actually use -> it comes from Earth seems a reasonable inference, IMO.
