Biosphere 2

Wow, what an interesting place to visit. In short this was an experiment in creating a habitable space, or Biosphere, (Earth is Biosphere 1) to be used on other planets as we explore the universe. Almost like a big sealed capsule that allowed for the production of oxygen, water, food and allowed for the elimination of waste. The entire facility sat on a big deep "bathtub" underneath, so even the soil beneath it was sealed and wasn't a part of biosphere one, or earth. A fully balanced, sustainable environment. Fascinating story, I do remember news stories from when it was occupied. 9 persons spent 2 years living here. Do Google this!
Got out about 1 or so and stopped in south Tucson for a delicious Sonoran-style Mexican lunch with margaritas! Quick stop by the U of A for 30 minute look at their art museum, and then home before 5! Beat the clock by one minute!Læs mere
