One of the things I've looked into rather heavily is Thermoaccoustic Refrigeration, as well as Cryocoolers, after seeing an article on an article on an electricity plant that stores excess generated off-peak power as Liquid Nitrogen, as well as an automobile converted to utilize that for power. There are a number of ways to reach cryogenic temperatures. The liquified air can be selectively purified, if necessary, but not worthwhile, imho, unless there is a specific need for it. Liquified air can be stored at relatively low pressure, in an insulated tank, as is easily seen at hospitals, in the form of Liquid Oxygen. Re gassifying the liquid air is where it becomes high pressure gas, by absorbing heat. That heat can come from any source, such as refrigeration, air-conditioning, solar heat, the air or seawater. The high pressure air can then be regulated and used to drive generators, power tools, even engines for propulsion, as if it were compressed air, or steam. energystorage.org/energy-storage/technologies/liquid-air-energy-storage-laeswww.highview-power.com/abcnews.go.com/Technology/vintage-car-runs-air/story?id=18738263en.wikipedia.org/wiki/Compound_steam_engine#Multiple_expansion_enginesIn the case of using a compound engine, it would be beneficial, as pointed out in the car story, to add more heat, so a radiator could be used to absorb more atmospheric heat, and used to keep the engine warm, as opposed to cooling it.
