Strengths
Largest closed system ever created, contained 5 wild biomes plus agricultural area and human hab.
Weaknesses
Required huge air conditioners to control temperature, utilizing 3 times the energy received in insolation.
Oxygen began at air normal (20.9%), dropped to 14.5% over 16 months. System was boosted with external oxygen at 16 and 23 months.
Lessons
Daily CO2 fluctuation was typically 600 ppm due to plant photosynthesis/respiration.
CO2 reacted with exposed concrete to form CaCO3, sequestering the carbon dioxide and, as part of it, the oxygen that had disappeared.
