Reddit reviews The High Frontier: An Easier Way

You might be interested in The High Frontier: An Easier Way - the authors use newer information which says rotations of ~6 RPM or below can be adapted to in a couple of hours, allowing for smaller habitats. One they postulate is a mere 112 meters in diameter.

In reality though if we ever manage to build rotating space habitats I guess that they will start way more modest, and stay that way across Musk's and Bezos' lifetimes. (By the way, it's interesting that Musk seems to be more interested in planetary colonization, while Bezos is leaning towards orbitals.)

There's another book from another O'Neil follower - The High Frontier: An Easier Way . After 40 years of more studies, they advocate building the first habitats in low equatorial earth orbit (O'Neil suggested the Lagrangean points), thus avoiding the need of massive radiation shielding, and small habitats - they suggest circumventing the problem of high rotation rates simply first selecting people that are resistant to disorientation (yes that varies a lot).

Even though, I will believe it when I see it. ;) So far we don't even have a "cheap" and reliable method to access space.
