Instead of trying to find an explanation as to why the Wraith couldn't use thicker and denser hulls for their ships, he goes at length to butcher a rather simple statement made by McKay.
Despite the fact that we've seen MANY systems in Stargate being boosted by a ZPM, and that's not just FTL but weapons, shields and even sublight engines, which is of importance here since an Aurora-class warship, the Tria, did reach 0.99999... c on STL with a ZPM, he's trying to spin doctor some simple statements into something truly absurd.
Never mind if the explanation could be simple : the ZPM allows to be build bigger and denser hulls, perhaps because there's some unexplained factor related to power which means that the Wraith cannot wait forever for a ship to grow and the only way to make a better hull is to provide more power now before the hull hardens, but also because, by following what Rodney said, they couldn't maneuver and maintain the structural integrity without snapping. Now, the ZPM also allows that, which perhaps means that the part of the Wraith systems that builds the hull could build super alloys but needed a specific power to do that, that is, to reach a threshold, and now thanks to the ZPM, this is possible. Those alloys considerably increase the structural integrity. However that would probably not be enough, and in order to fit with McKay's statements, we may need to assume some reinforcing structural integrity field at play, all of which also allowing a greater engine structure which can tolerate higher pressures and temperatures, and eventually some better force fields there as well.
Add better sensors and better weapons as well.
And voila.
If the hull was merely larger, McKay would have just pointed it out, instead of saying that it was denser and larger, especially since by the time he said that, the ship was largely completed anyway. They didn't observe the ship in its infancy.
He's arguing for something stupid, like the hull is first grown super dense, then it's expanded from its current mass into a larger hull, so the density actually drops back to the usual density.
That's just so convoluted at this point! Not only that, but the analogies he uses to defend his position, like the crab hull, is not even relevant, unless he could prove that a crab grows a new and denser shell, and then "inflates" it without adding more mass.
Of course, anyone logical would say that the crab is just growing more "hull". Not that it's getting denser.
It's just so dumb. We've seen drones puncture hiveships left to right, even if fired in small numbers. That is, going through ships which are either 11 km long or at least around 5 km long.
Atlantis fired drones and they weren't even denting the damn thing, and McKay said it would be impenetrable.
Does Uncluttered Ears understand?
Impenetrable means which cannot be penetrated. It's not just more armor; it's better armor.
The amount of gymnastics is ludicrous.Enemy at the Gate wrote: MCKAY

It's growing.

What the hell are you talking about?
MCKAY
That's what they're doing with the surplus energy—using it to grow a larger, and if I'm reading this correctly, significantly denser outer hull. It makes sense. Normal hives have a limit of growth. I mean, any bigger or heavier and they become impossible to maneuver, let alone get into hyperspace. I mean, you make a simple left turn, and you're torn apart by your own inertia. But with a ZPM…
SHEPPARD
I get the picture. What does that mean for us?
MCKAY
When they're done, my guess is that hull will be all but impenetrable.
Now, this imbecility aside, we can also observe that a ZPM is indeed offering insane amounts of power. Simply put, on the same vein as the episode "The Seed", we not only have again a confirmation that Wraith ships grow out of energy and can tap ZPMs, but that said ZPMs can provide phenomenal amounts of power.
We're talking about adding substantial mass to a ship that is 11 km long.
That is not merely providing extra tonnes, but increasing by a considerable margin the mass of a ship that is bound to be worth several billion tonnes.
RSA had found that the Executor, while being 17.6 km long, might weight as much as 6.32 to 12.65 bn tonnes.
Contrary to a normal hiveship, the ZPM powered hiveship, or super hiveship, has armour covering sections which were usually not to much covered. Besides, the vast gap inside is now completely filled. A hiveship is also thicker than the Executor.
We can assume, at least, that the super hiveship would have a mass about two thirds of the Executor's.
That would be at least 2.21 bn tonnes.
In order to represent a significant difference between a hiveship and this new beast, the extra mass of the later, which is also stated to be denser and making it impenetrable, must be a large portion of its total mass.
Let's just round that to 1 bn metric tonnes.
That's 89.876 e27 J.
21.481 exatons.
Now, for how long as this amount of energy been used?
To answer that, we need to know since when the ZPM powered hiveship project began:
We can, eventually, take an extremely long period. Say a year.Enemy at the Gate wrote: WOOLSEY: All right, then tell me this: why now? You've had those ZeePMs for over a year.
TODD: The organic nature of the Hive creates certain incompatibilities with Ancient technology. I put my best scientists to work on this project and recently one of them succeeded.
WOOLSEY: Only he didn't wanna turn it over to you. He decided to keep it for himself. And now you want us to help you kick him to the kerb.
TODD: What you really need to know is that this Hive is a work in progress. It has yet to reach its full potential – which means if you attack it now, you may be able to destroy it, but if you hesitate it will be too late ... and this Hive will be unstoppable.
Ok, that's roughly 2,847,983 e15 W, nearly three million petawatts, low end.
That might get multiplied by 6 or 12 if the energy consumption was spread over one or two months.
This is not a surprising value. It works with the Tria's deceleration, it works with the need to tank a mass extinction blast, and it even works with depletion rates for ZPMs as obtained from other cases.
Finally, it clearly demonstrates that a ZPM does have that much energy to tap. More than enough to completely blast a planet apart on sheer DET.
