The Oxygen Bottleneck For Technospheres
On Earth, the development of technology required easy access to open air combustion, which is only possible when oxygen partial pressure, P(O2), is above 18\%.
This suggests that only planets with significant atmospheric oxygen concentrations will be capable of developing “advanced” technospheres and hence detectable technosignatures.
