>Why are rotating part exposed?
"Space cave," is what I >>11308309 said. No windows.

>filled with water and hydrogen
Pretty much, but not free hydrogen. Instead you can just use plastic. Like polyethylene. The ratio of carbon atoms to hydrogen atom is 1:2, respectively. There are programs to develop plastic shielding with as many hydrogen atoms as possible squeezed in. It seems to be the cheapest and lightest material to use that works well with primary and secondary particles.

Much of the artwork is rather old and newer stuff is normally based on the old designs. All of which are incorrect. The biggest error is having windows. You simply can't have unshielded windows in space. even the coupla on the ISS is heavily shielded(pic) and those shields are only open when someone is inside for a limited amount of time.

The best you can hope for are interior lights simulating sunlight or whatever your needs are.

why do so many hypothetical space habitats use such large windows, wouldn't that be unsafe
