Totally came to say that. I rinse but don’t use soap in some circumstances.

That was worth every second it took to read.

For number 3 and the slip ring. I have always thought, just make the stuff on the end self sufficient. Essentially make two spacecraft. One to run all the experiments in zero ish g. And the other to be like living quarters. You can even make them suit up to commute. But you would need one heck of a long arm to make the 2 palatable. Maybe 3 craft, two way the hell out there attached to some crazy long tethers. One in the middle. Then some kind of speed sled thing to get a person from the outside in or something. Probably need to worry about balancing out the change of weight due to the sled (and person) moving from outside in and such.

Ringworld is solid. Just about everything written by Larry Niven and Jerry Pournelle is good. When they work together, you get some solid stuff.

And books by Andy Weir are all very good. But you can cheat and watch the movies.

I read the chronicles as a teenager because of all the big obscure words that often ended up on the SAT exam. Helped my score. Decent story too, lol.

I’m awake, but I’d rather not be.
