Bob: Nonononono. Actually, personally, I'm pretty relieved that you're *not* going with a forcefield. My mistake there. As I'd said, the right sort of biomodded plant could do that pretty quickly and easily. You could likely come up with a not-quite-plant that could do it as well, if you didn't want the dome to be green. It actually makes the whole structure *more* plausible, rather than less.
(now, if you'd wanted to try to build the dome with hardtech and sweat, that's... bizarre, and also a tch worrisome.)
