A fascinating alternative is “a pressurized ETFE membrane… periodically anchored to the ground by steel cables.”
In plain language: Fiber-reinforced rip-stop ETFE (a thin, strong, light, transparent material used for yacht sails) is used to make a roof and walls with the area under it pressurized and anchored using very tall cables, hundreds of meters high or more, to create a sky. The covered area is huge, the size of a city, compartmentalized for redundancy. People are able to go about their daily lives without use of space suits and it doesn’t feel like you are “inside”.
Okay but what are we gonna do if some giant space cat decides to claw the barrier? I’ve always wondered what the inside of a air mattress is like.
Great link
