CO2 has to be pressurized to 74.97 psi to remain in the liquid state. At any less pressure, it goes straight into it's gaseous state; it will become solid (aka 'Dry Ice') at 14.7 psi (1 atmosphere) at below -78.5 degrees Centigrade. Therein lies the problems to be overcome to use it for FE cooling purposes. I’ve been thinking about this for a while, but not very seriously, as I don’t have the resources to fully explore the possibilities . . . .
