General
This mod is designed to alleviate the common hassle of storing huge quantities of gas in a reasonable amount of space, in particular on salvage ships which usually collect the cargo of their targets before deconstruction. Gas compressors are basically gas tanks, with 8 to 16 times the capacity of the vanilla tanks...if you ignore all the extra requirements that come along with such capacity.In order to achieve such capacity, the gas must be cooled and compressed so far that it condenses into a liquid, and then it must be kept cold so that it does not revaporize and rupture the container. What this means from a usage standpoint is that these tanks have a significant idle power draw - on the order of a few megawatts - and a large power cost to actively pumping gas in or out, more than ten MW.
It also means that should that a failure in power supply will result in failure of another, much more violent sort. This will also occur if a pressurized tank is disrupted in some way; you do not want to make the mistake of suddenly releasing a large quantity of pressurized, possibly explosive gas, by grinding or shooting a hole in the tank.
