A few random comments:&lt;p&gt;- It’s underlaid by a dense sprawl of machinery the size of a football field, which is constantly working to create and maintain the above biomes.&lt;p&gt;- The “lungs” are auditorium-sized rooms with a ceiling that’s free to rise and fall as air pressure changes due to temperature, reducing stress on the structure. You can walk up inside it, with air rushing past you in the connecting tunnel.&lt;p&gt;- There’s a library at the top of a short tower, maybe two stories. We were told the crew didn’t use it because food and oxygen deprivation kept them too weak to climb the stairs.&lt;p&gt;- Golf cart sized air vents create what really gets subconsciously recognized as natural wind, not artificial blowing. It was so pleasant that I’ve become determined to replicate it in my home someday.&lt;p&gt;- There wasn’t a predecessor, “biosphere 1” refers to Earth.</text></comment>
