On reflection, I believe the nitwits actually named their failed enterprise, the Biosphere.

Actually, they were even goofier than that. They named it "Biosphere II" since our lovely planet is "Biosphere I".

Hippies are so silly.

Lots of mistakes were made with Biosphere II -- the most serious (and unforgivable) being cheating by pumping in fresh air.

Despite the mistakes (or maybe because of them) some valuable lessons were learned. One of the purposes of Biosphere II was to be a prototype for an extraterrestrial colony (e.g. on Mars). We now know all sorts of things about how not to build a colony on Mars.

BTW -- Biosphere II is still standing -- and open for tours.
