@elonmusk@fermatslibrary Every idea will face difficulties but we could overcome it.
We may make use of radiators that equip with forced vapour chaner to accommodatethe vacum space and take advantage of the great temp diff.
For the freezing point, just choose novec or ammonia that with low freezing point
@fermatslibrary A solid sphere would be extremely inefficient and impossible to build with known materials, however a many-layered satellite swarm requires no new physics to work.
AI compute would be done locally by the satellite with only the results sent to in-space or maybe on-planet hubs.
In 1960, Freeman Dyson proposed a megastructure to capture all the Sun’s energy - the Dyson Sphere. That’s what a Type II civilization needs. At ~2.5% annual growth (like 1960–2025), we’ll need a whole star in 1,200 years. A Dyson Sphere isn’t sci-fi - it’s a forecast.
