Is a Dyson Sphere worth the up-front cost if a civilization has fusion? If not, then maybe that's the answer, even without exotic power generation methods we haven't even imagined yet.
And yes, I understand that fusion is "always 10 years away" even with Helion, but it does seem like it's coming within the next 100 years sometime.
- AtlasBarfed 3y agoThe assumption comes down to whether that fusion is cheaper than solar in space. Considering fusion or fission can't beat solar on the planet with solar being hamstrung by our atmosphere...
- zabzonk 3y agowell, on my understanding the output of a fusion power plant is about the same as a fission plant, but possibly cheaper and/or cleaner. that isn't much compared with the energy radiated by a star.
