Its purpose is to provide: dense distributed launch/capture corridors large-scale routing geometry attachment points for high-temperature radiator fields buffering volume for material and coolant traffic alignment and vibration-control structure for the mature transport system...

Reading the "endgame" section, and I feel that some serious thought ahould be given to what the replicator colony will do after it has finished dismantling Mercury.

This reads like an LLM plagiarizing this video from Kurzgesagt:

Kurzgesagt didn't invent the concept of disassembling Mercury to build a Dyson swarm. Stuart Armstrong proposed it in a lecture in 2012[0].

Bootstrapping an electronics supply chain on another planet seems harder than building the dyson swarm itself.

> The mirror fleet does not increase the total power available to the project; Mercury still intercepts only a fixed amount of sunlight.

I think I must be missing something important, because this doesn't make sense to me. If you put your mirrors in orbits where they don't block the dayside surface (sun-synchronous?), then they increase the total surface area receiving solar radiation.

Yeah, orbital mirrors essentially expand the radius of Mercury, increasing the sunlight available. Terrestrial mirrors would ensure that light makes it from the sunward side to the dark side of the planet.

1-6 years can't be realistic can it? does someone have a better estimate of how long this would take?
nacozarina [3 hidden]5 mins ago
this seems to ignore the fact that Mercury is way too deep in Sol’s gravity well to be useful, all it’s looking at is Mercury mass.
Stefan-H [3 hidden]5 mins ago
Why does being so deep in the gravity well pose an issue? If you are assuming the Dyson swarm is intended to go back up the well then sure, but that isn't necessary.
ethmarks [3 hidden]5 mins ago
Could you elaborate? Why would being deep in the gravity well be a non-starter? I thought Mercury's proximity to Sol was a huge advantage because of the ample solar power which would make planet-side manufacturing easier.

What about orbital mechanics? Wouldn't that create issues with/for objects in the solar system?

I encourage Dyson sphere enthusiasts to listen to the interesting argument that Dyson spheres they may be deliberately designed as an "sounds neat but is impossible" filter joke, ref: https://www.youtube.com/watch?v=fLzEX1TPBFM .
MarkusQ [3 hidden]5 mins ago
Sped through that, couldn't stomach the whole thing. Is there more to it than "argument by sneering dismissal"? (Basically, so far as I can tell, her point seems to be "this was intended as a joke to see if you're stupid, so if you believe it, you are, neener-neener!")

Somehow I new before clicking that it was going to be Angela.

Please someone, send grey goo to Mercury.

Does Mercury not have any useful radioactive material to provide more power?
andrewflnr [3 hidden]5 mins ago
I guess it might. I wouldn't plan on it without a very detailed survey though, to say the least. Whereas solar is definitely right there. (And you still have to worry about cooling either way.)
NoMoreNicksLeft [3 hidden]5 mins ago
Are there reactor designs that could work up there? There's not much water for coolant.
ethmarks [3 hidden]5 mins ago
There are other substances that can be used for reactor coolant. Molten salt reactors are actually substantially more efficient than water-cooled reactors because they have a higher operating temperature. You can also use liquid metal as coolant, such as lead or bismuth.

I am such a sucker for technical Aspie writing. I've seen it mistaken for LLM output many times but this is not that.

its not? how can you tell?
