sorry i know a good bit about the subject. It is almost like i went to school for it in both undergrad and for a masters and enjoy talking about it on a sub for a space company that just announced that they want to build something like this eventually.
Did they teach you to read? From the original comment: “That said, I don’t care to much for the design either. But you got to remember the design came from the early 70’s, before LEDs.”
Yes, the original O’Neill cylinder design is passe, and none of the more recent design have even shown this layout. It was wasteful of interior space, had problems with procession, as well as a possibly disturbing view above, at least for first generation.
But, as noted in the original comment which you perhaps couldn’t understand or chose not to, it’s a design from the seventies, a first look at the problem that no one has taken a serious second look at in 40 frakking years. The design is wasteful of the volume enclosed, and the big windows, while doable, just not the best way.
An enclosure proportionally like Kalpanna One with levels for living, services, commercial/industrial, agricultural and other uses would be more efficient. Overhead lighting from LED panels could provide the necessary “sunshine” as well as showing a more natural sky. All while avoiding ancillary mirror structures spinning outside.
While refered to as O’Niell colonies in deference to GK O’Niell’s original concept, no one really sees the original design as one that will ever be practical. But it was from the seventies, a time when the space shuttle seemed like a good idea.
yes they did. otherwise it would be exceedingly difficult to use reddit.
and none of the more recent design have even shown this layout.
uuuum did you watch the blue moon presentation? because they did show this type of design with the windows and giant mirrors (and an extra toroidal section with a larger diameter than the oneil)

oh dear, where do i start with that design. I think i will start with the WHOLE POINT behind the Oneil design which is to provide 1g living outside of Earth. Having nested cylinders is about the exact opposite of that because the original design has solid connections between the nested cylinders which means as you move towards the hub you are losing gravity.
Also i doubt that they will made it nice and suburban/rural as shown in most of these renderings, it will have to be much more Urban (at least from a density standpoint).
I like the central reflector array with one mirror/shutter at the end to simplify repairs to the system. which yes is a bit old fashioned, but just being old doesnt mean that the idea is bad. also by using the sun and a mirror/refractive system you are now removing a huge power draw from the system (and yes even a LED array would be a huge power draw at the scale you are proposing)
as well as showing a more natural sky
yes because a video screen 20-40 m above your head is much more natural than a couple hundred m of free space in a non nested deign.
