There's some biodomes in England (The Eden
Project in Cornwall, England), but they're not sealed. They're a tourist attraction and research center. Amazon (the
online seller) recently made a biodome (also not sealed).
If you like fiction reading that is a mix of scifi,
permaculture, and fantasy, the Biodome Chronicles (
https://www.amazon.com/Legacy-Biodome-Chronicles-Book-1/dp/0991345371) might be up your alley. I really enjoyed them! The
books are set 50 years in the future, where a group of SCD (Society of Creative Anachronism--aka "renaissance fair") people made a biodome where they did a Live Action Role-play of living in medieval times, using
permaculture principles, to survive in a totally enclosed environment, and raised their kids to know no advanced technology. Really fun and thought-provoking books!
