Title: How to Build a Dyson Sphere - The Ultimate Megastructure
Post by: Unbeliever on December 22, 2018, 03:32:40 PM
I couldn't find an existing thread for this, so I started a new one. I wish I could be around for the day we complete one of these!


QuoteIf humans want to expand into space, it will take us incredible amounts of energy. How do we do that? Easy: we will just use the sun’s energy by realizing the most ambitious construction project in history. This is how it works.

I'm surprised we'd only have to use one planet for this, I was under the impression we'd have to use all the planets we have access to.

We'll need something like the Fireball XL5 to get stuff off of Mercury.

Is this an all-or-nothing deal or could we build a partial Dyson swarm and gradually extend it?  Because doing it all in one go sounds too complex/expensive to realistically accomplish anytime soon.

It probably would take a long time to finish the whole thing, but I don't see why we couldn't take a while to get the whole thing done. Once we get started we could already use whatever energy we'd be getting in just the partial swarm. And as we continue the energy we get would constantly be increasing.

It would take a long time......like the first part would have outhouses and clubs and the last part would have devices that attach to your parts and literally suck the crap out of ya and alongside the shitter is a swinging bubble with 2 mag nuc bullets that can blow apart a moon. And all the peeps be like..."hey, lets go check out the outhouse"....and there ya have it, our fascination with bodily scat will make it impossible to finish the damn thing.

Looked it up.  A dyson ring (a swarm of satellites, all with the same orbit) would suck up a lot of energy while being a relatively simple, easy-to-maintain option.  And the cherry on top is that it can be perpendicular to the Earth, so it wouldn't block any sunlight coming to the Earth.

We could call it Ouroboros, perhaps.

Hopefully not a Mobius strip, I think that would be unstable.

I've been waiting to see if we could detect a Dyson Sphere being built.  Its "possible".  And  a suggestion of one (though a couple years old)  https://www.sciencealert.com/researchers-just-found-a-second-dyson-sphere-star.
