Artificial Biospheres In Space

Mike, I want people to thrive, not simply survive.

"You have to weigh the issues of quality of living against the risk
of a habitat-wide disaster. The odds of such a disaster are
considered extremely low by those who have done actual calculations
rather than relying on gut-feels (which may derive more from science
fiction than anything). One advantage of large volumes is that even
given a rather large hole, blow-down times are long, meaning a
routine repair rather than a sudden emergency. And as to the
quality of life trade-off, what is the longest time that any
human being has voluntarily lived inside a small metal room?"

The O'Niel designs are appealing and aesthetic and I expect like
designs will be built in the future. They can them easily drawing
future tourists and become profitable and I'd like to see one made
in L5.

On the practical side they might play an important part in child
development. I'm concerned about how kids will develop up there.
