Sure, but for context, normal atmospheric pressure is 101 kPa. 1 GPa is a lot closer to ambient than 250+ Gpa. AFAICT [0], nothing with a critical temperature

Sure, but for context, normal atmospheric pressure is 101 kPa. 1 GPa is a lot closer to ambient than 250+ Gpa. AFAICT [0], nothing with a critical temperature above the freezing point of water (273.2 K) has yet been discovered, and everything with a critical temp above "dry ice" temperatures (194.6 K) needs at least 155 GPa. As such, this would seem to represent truly exponential progress in terms of both critical temperature and required pressures. With luck, we'll be able to carry these things a bit further to make it actually practical for some applications that currently require cryogenic temperatures.
