All of that was reasonable and understandable.
To me, the realm of the fantastic emerged when we learned how Biosphere 2 "breathes."
|Caves of Wind|
There are two domes flanking the Biosphere..you can see them in the upper picture. These are its lungs..huge, circular rooms in which massive aluminum disks weighing several tons virtually float in the air, pressing the atmosphere, maintaining pressure throughout the connected, glassed-in laboratories. Walking into one of those "lungs" and looking overhead is a humbling experience. And when you leave..it practically blows you out the door.
Incredible. Beautiful science. Learning by doing--discovering what we don't know..making sure we maintain what you do know and, hopefully, improve it.
Biosphere 2, inside Biosphere 1.
What a marvelous day.
