Cryotank In science fiction, cryogenic tanks are used to freeze people. "cry-" is a Greek prefix which means "cold or freezing", hence humans are stored in the tank frozen until a future date. Cryotanks are found in some science fiction films such as "Prometheus" (2012) and "The Host" (2013). Cryotank Cryotank or cryogenic tank is a tank that is used to store frozen biological material. The term “cryotank” refers to storage of super-cold fuels, such as liquid oxygen and liquid hydrogen. Cryotanks and cryogenics can be seen in many sci-fi movies, but they are still currently undeveloped. All that needs to
Helium cryogenics Helium cryogenics In the field of cryogenics, helium [He] is utilized for a variety of reasons. The combination of helium’s extremely low molecular weight and weak interatomic reactions yield interesting properties when helium is cooled below its critical temperature of 5.2 K to form a liquid. Even at absolute zero (0K), helium does not condense to form a solid. In this state, the zero point vibrational energies of helium are comparable to very weak interatomic binding interactions, thus preventing lattice formation and giving helium its fluid characteristics. Within this liquid state, helium has two phases referred to as helium I
