How these power cells are called?

"Isotropic Fuel Rods".

As for the rest of the crap you posted, again, you lack creativity. 40k is not a hard science setting, nor is it really even a hard-set canon type setting. All of the things I described are well within the technological capability of each of the factions I mentioned. Just because an Ork has not yet been recorded as having invented what I jokingly referred to as a "sunblasta" doesn't mean they couldn't. They developed shield and teleportation technology on par with the Necrons, a faction that is capable of bending the laws of nature to their whims without using the Warp. And unlike the Necrons, the Orks have access to warp-technology. It would hardly be that strange for a crazed Big Mek to create a temporary portal between a star and the battlefield, that even if it existed for just a split second, would cause a massive explosion of heat at the target.

What I'm doing is pointing out that, if GW wanted Dyson Spheres to exist in 40k, they'd barely have to do anything to justify them and their use for any number of factions. They could even make it a battleground for armies to fight on, just for funsies, without ever even describing the actual use of the thing.

You confuse creativity with fantasy and lack of understanding of rules within universe runs by. While W40k was always scarce on technical details, it remained consistent on a general scale of what each faction is capable of. Sometimes they do have detailed explanations of how things work, locked away in arcane and unknowable tomes which even most hardcore W40k never read. Examples which I had heard here is simply nonsensical and it is the issue with authors too as a whole. Nowadays writers are lazy, they create nonsensical story with no research, no effort put into it. Long gone are days that even names of characters meant something and were taken from bible or other culturally influential sources. What we get in the end is a bolter porn which is disgusting to read, sometimes it gets so obscene that I just skip action all together as outcome of it is extremely predictable, unrealistic and bothering. As for stories itself which writers come with are called as magic plot macguffins. It is considered as lowest form of literal excellence as story in itself is inconsistent with world at large, falls apart under logical scrutiny and is most clique way of writing any story.

And then there's another idea-- why not transport that energy directly to a target, weaponized?

What would you call it? Starkiller base?

Think big - a Dyson sphere with the radius of the earth's orbit has the same surface area as half a billion Earths. If it captures the energy of the sun, it has 3x10^26 Joules to play with - every second! That's 300 million million million million Watts.

It has an equatorial radius of 942 million km, and will take 21 thousand years to walk around. At Earth's current population density, assuming handwavium gravity, it can support a population of 350 million trillion. Entire civilisations rise and fall without your civilisation even hearing about them. Or... you can transmit radio or light messages across the thing in about 1000 seconds 16-17 minutes)

If it rotates to create equatorial gravity, to withstand the tensional stresses, it needs a material as strong as the strong nuclear force. Congratulations, you've created armour impervious to anything short of a strike by an astronomical body.

All that energy - you're going to need it. To simulate 1G of gravity round the equator, it will take tens of thousands of years worth of solar output to spin it up to the correct rotational speed.

These things are vast beyond understanding on every scale.

And frigging awesome! Lol

To be honest I'd love to see them actually have one of their battlefields be on the outer surface of a dyson sphere, with the armies in question essentially fighting over its control nodes.

Let's avoid porting Halo into 40k, please?

I was more thinking Total Annihilation, because TA's machineworld and dyson sphere battlefields were amazingly fun.

Ernesto, I just can't take your posts seriously. People have actually given examples of dyson spheres existing in 40k. Your complete lack of creativity and complete lack of knowledge of 40k combined with your arguing that things can't be possible within the setting is just annoying at best.

I pity you. And I'm done here.

Necrons during War in Heavens were entirely in league of their own and it is foolish to compare races of today to Old Ones. There are some entries in lore which do not make any sense all together too and it is best to ignore them. This is why we have constant retcons for anyways.

Literally wrong.

Um, Lazarus for starters. You know what someone interceding is, right? Bile's ship being named the Vesalius? One of his former pupils being called Oleander? And those are just off of the top of my head from incredibly recent stuff.
