Strengths
Chlorella algae were used to recycle air breathed by humans,cultivated in stacked tanks under artificial light.
Weaknesses
Twenty 6 kW water cooled xenon lamps supplied a level of light comparable to sunlight in each of the 4 compartments. The facility used 400 kW of electricity.
Lessons
Each human needed 8 m2 of exposed Chlorella. Air was purified of more complex organic compounds by heating to 600°C in the presence of a catalyst.
