I had an idea for a space habitat once that was sort of like a hybrid between this and an O'Neil Cylinder. I mainly came up with it for a sci-fi story I had, and it was intended to solve the problem of a day/night cycle without mirrors. I jokingly call it a "Daniel Torus" (because my first name is Daniel and my last name is hard to pronounce lol). Anyways, it is like a ring or torus, but the length of the tube is roughly similar to the diameter, thus making the length from one end to the other the same or almost the sane as the diameter. It would have a transparent inner edge or covering, stretching out to the sides to allow as much view as possible. It would be anywhere from 5 to 30 miles in diameter and relatively thin, or at least as much as the superstructure allows it to be. It would rotate at the speed required to simulate .8 to 1.0 Earth gravity, but here is where it becomes different. I don't know if this is possible because I not an engineer, but it would also have a slight sideways rotation or drift. While it spins much faster around the axis, it would also spin or rotate much more slowly along the axis perpendicular or sideways to its main axis of rotation. This secondary axis of rotation or drift would require 48 hours to complete, so it would go slowly, but the idea is to generate a day/night cycle. Because the sun would be blocked out when the main axis of rotation (the one required for gravity, let's call it the X Axis) is facing away from the sun, as it rotates so the X Axis faces the sun, the sun would become unblocked as it comes out from behind the outer body of the cylinder eclipsing it, and moves into view of those inside the cylinder, before reaching the highest point in the place directly in the direction of the X Axis. Then, as it keeps rotation around the secondary axis (the Y Axis, the much slower one), the sun would go back and be concealed by the outer body again. Since it rotates along the secondary axis, the Y Axis, every 48 hours, this would provide roughly 12 hours of day and 12 hours of night. First, it would be 12 hours of 'night' as the sun is concealed, then as it rotates along the Y Axis, the sun would become unconcealed again, and it would be 'day' for 12 hours. Then, the sun would become concealed again for 12 hours of 'night,' then become unconcealed again for 12 more hours of 'day,' and as it becomes concealed again, it would finish the secondary rotation cycle. So 48 hours in total to complete one rotation along the Y Axis, for two 12 hour periods of 'day,' and two 12 hour periods of 'night.' The rotation would be kept in check and adjusted by small thrusters along the edge, and there would be a central system of cables or fixed structures going to a central terminal, with elevators attached, allowing boarding craft to dock in the center and descend into the habitat. Inside would be a pressurized environment, with cities, houses, and parks to create a more livable atmosphere. The highest point the sun would reach during the day would be about 45 degrees from ground up, from the view of those at ground level. There could still be smaller mirrors at the center terminal to aid in temperature regulation and bringing in more sunlight, but the goal is to provide a more naturalistic day/night cycle, and so the inhabitants can directly see the sun. The outer transparent covering would need to be strong, and would likely be made up of a honeycomb-like metallic structure holding the window panes in place, to allow easy replacement in case of structural compromise. The windows would likely be made of several layers of translucent materials, reinforced by a woven microscopic and macroscopic fiber structure to absorb micrometeorite impacts. There would likely be an advanced detection system to detect larger meteorites and dodge them. There would also likely be a system of emergency sealing fluid or gel in the windows, supplied by pipes, that would rapidly seep out in case of structural failure of one or more windows, that would then accumulate and freeze up, sealing the hole to prevent catastrophic structure failure. There would also be emergency safe rooms with emergency oxygen and supplies in case of total structure depressurization and failure, so that occupants can get to safety before all the oxygen leaks out and be rescued later. Anyways, I don't know if anybody had this idea, but that is one idea I had for a space habitat.

If Starship really becomes as cheap and reliable as SpaceX thinks it will it would allow resource harvesting and manufacturing on the Moon to become a reality. That opens up every other cool space thing we've ever imagined, including giant space habitats. I really hope those are the kinds of things we decide to do with it and any other reusable space vehicles we come up with. Living anywhere accept somewhere like Earth isnt going to be good for us. Once we have in space resource utilization we can build Earth like habitats wherever we like. As hard as it seems building these huge things its a lot easier than trying to rebuild an ill suited planet to be like Earth. We could power Earth with energy we beam down from space, zero pollution or finite resources required. The conversion losses of beaming power down dont realy matter when the energy source is free and abundant. We really could change the world for the better. We just need to learn to harvest and build out there first. I wish more people talked about things like that instead of the flashier ideas like going to Mars.

"Starship" lifts only about 100 tons to orbit, about the same as the Ssturn-5. NASA planned to quickly move beyond such small things. Very large boosters have been designed since the '60s. There were and have been no technical problems with them, just contrary political will. Look up "hazegreyart" videos of things like the Boeing "big onion" or Douglass ROMBUS or Boeing AMLLV, or Convair Nexus

Given that this is entirely feasible for us, now (anytime since the '70s, for reasonable costs), I've always thought that it deserves an episode deep dive. No fantasies about the O'Neill "Island 3" (which never was a real design proposal) or Bishop rings or the bad SF so-called "dyson spheres" included. This was worked out in hard numbers and nuts & bolts, and with real economics. This isn't from fiction and isn't just for a lark "wouldn't it be cool if..." or just someone's brainy daydream. Mining engineers who consulted in the NASA studies said that the mine on the Moon would barely keep one tele-operated bulldozer occupied, and the open pit mine would be like 3 football fields ("futbol" for international units), ~4 meters deep on the Moon. Using what they knew from Apollo samples, and bringing up all the water and process chemicals from down here. They said that if NEAs turn out to be more numerous than what they knew then, it would be even better (NEAs have turned out to be very much more numerous and beneficial than they knew)

Larry Niven's Ringworld...and maybe even Philip Jose Farmer's Riverworld. Hah! The 70s were the greatest decade.

Boosters bigger than the hopefully upcoming SpaceX BFR (100 tons to orbit is about like the Saturn-5) have been designed since the '60s, but congress decided to go with the hyper-expensive and incapable Shuttle, and to spend far more to build big military to fight over oil. Also note that when you're mining the Moon or NEAs especially, you've ended all scarcity of raw materials like metals, and you've dropped the price of previously rare metals down through the cellar. This habitat was to be for workers building Solar power satellites, so you've ended scarcity of energy, and oil is not used for primary energy anymore.
