“It has lousy swimming capabilities and gravid females — females with eggs and juveniles in her pouch — are especially non-agile. This is in contrast to some species [of the same family of isopods] which are free-living and can occur in such large numbers that they can deflesh a fish or body entirely.”
Solid louse joke…although technically an isopod. I’ll never look at a rolly polly the same…



CO2 is a nice substance for this due to its relatively high temperature of fusion at modest pressures (and cheap ubiquity). I’d wondered why this wasn’t more of a thing with air, using excess energy to liquefy it, to later let the LN2 to be vaporized/expanded in a turbine and the LOX to be used in rockets or something. But deep cryogenics are more challenging.
Or maybe use excess power to electrolyze water for fuel cell use later?
But yeah, CO2 makes a lot of sense despite its relatively poorer specific heat ratio for adiabatic expansion compared to mono and diatomic gasses.
