Of Water and Ice...(Seriously?)

Well, considering we're in space, if you need ice of anything it's enough to open an airlock after depressurizing the compartment. You wouldn’t even need metal boxes: a condom would be all the recipient you would need…
Just repeat it, repeat it ad nauseam.
I hardly think you need a specialized facility to convert gaseous or liquid matter in its solid form, when you’re already in space (not with the technological marvels you already have on the Arks/Nexus). Or, better yet, just jury rig a conduit and make it pass outside the Nexus or the Arks: by dispersing heat in the vacuum, gas would liquefy by condensation. The trick would only be regulating the flux so that the conduit doesn’t obstruct itself with the ice: so, if you need liquid CO2, or O2, you can’t use the same “exposed” length you would use for water’s vapour (Of course, I’m implying you already have reserves of the resource you need to liquefy/ solidify).
You need it frozen (I would ask why, but ok)? Just build a container of omnigel, fill it and exposed it.
Dissolve the omnigel and rebuild the cage and do it again and again…
But again, this is a basic solution with very limited in universe tech.
From ME, I expect at least a laser cooling system, similar in functioning to the Avalanche heavy weapon from ME2.

For this blunder, I’m going with a mistake on the writer parts: maybe it meant hydrogen (who was used in its metallic state to fuel the engine of the SR2). The word “Hydrogen” shares the root with ὑδρο, “water” in ancient Greek. So, maybe it was meant water & hydrogen (metallic), and instead we got water and ice.
What surprises me more is that the mistake got the green light… no one said or thought “what am I reading?” and decided to solve this inconsistency?
I suppose they are wasted by the stress from the upcoming launch, but come on people: good stories are built in their details…
