The Artchitechs must have been on an LSD trip when the designed that idea.
Who the hell would want to be in a structure hanging on cables thousands of miles long?What a nightmare.
I would think the cables would break just from their own weight, much less a huge building attached.
Plus that asteroid won’t stay in orbit with a constant pull downward......................
The “space elevator” concept has actually been around for decades, since Arthur C Clarke thought it up in a sci-fi novel. People have been trying to engineer it into reality since then. Lately we’ve actually created materials capable of withstanding the incredible tensile strains; problem now is actually building the >30,000 mile strand and getting an orbiting rock big enough to tether it to. Once the cable is built, then running elevator cars up & down it is quite simple, and cuts to-orbit costs to near free.
This “hanging building” concept is clearly just a variant of it, solving the problem of tethering the Earth end of the cable by, well, not tethering it.
Stone-cold sober engineers can come up with some pretty wild concepts if you encourage them to. We don’t think like the rest of y’all...
