How would it be possible to vent water vapour into space in a so called vacuum?
By exposing it to space.
All provided in the schematics.
Again, if you want to ask questions, stop claiming its fake, and admit that you have no reason to believe it is fake.
Otherwise, justify your outright lies against it.
Once more:
How much oxygen could that tank hold? Not as a time based unit, but either as pressure and volume, or mass (and show all working).
How much oxygen does a human need every hour, and what is your justification for this number?So far the closest you have come to addressing this is providing a useless 8 litres, with no indication of if that is 8 litres at normal atmospheric pressure, or 1000 atm, or as liquid. (And you also provided no justification for the claim of 8 l)
And for the second question, the closest you have come is a BS lie of 3000 l per hour which is easily shown to be pure garbage.
I don't think you understand.
Do you mean understand that you need to continually lie as you can't justify your claims? I understand that quite well.
Or did you mean understand you have no idea at all how units work? Because that seems apparent.
kW is not a unit of energy, it is power, it is a rate of energy transfer.
It doesn't matter if you have 1 kW for 1 hour, or for 100 hours. It is still 1 kW.
What you are thinking of are kWhr or J (noting there is a conversion factor of 3600 to go between those).
Your water, batteries and oxy issues are ridiculously wrecked. It's a no go and only fantasy keeps it as some kind of working pretence.
No, they are pathetically dismissed by you, with no justification at all.
That is not "wrecked".
You are the one promoting fantasy, not us.
You are the one rejecting reality, trying to pretend it is fantasy because you have no rational arguments against it.
You cannot boil to the vacuum of your space without having some kind of medium for it to boil off into.
And yet again you show you have no idea how basically anything works.
You do not need any medium at all to vent.
If you understood how gas actually works, instead of continually dismissing it with your fantasy, you would understand quite well that no medium is needed.
All that is needed for water to boil off is for the water molecule to have enough energy to leave the bulk. The only bearing the medium has is that if it contains some of the molecules it will be colliding with the bulk and potentially being stuck.
If you want to disagree, feel free to try justifying why boiling should magically require a medium.
You don't have anything, do you?
No, that would be you.
You have nothing to justify your claims. All you have are pathetic lies and dumb questions.
Do you not understand how insulation works? 
Yep and it would not work on the so called moon vacuum.
Why?
What magically stops it?
Take a look in the sky and see it lit up like a beacon.
Do you mean the night sky, where it is basically main source of light and your eyes have adjusted to darkness?
Or during the day where it is faint and almost blends into the sky?
Try being in a nice dark room, then stepping out to bright daylight, and see the ground lit up like a beacon.
No brick buildings and in a vacuum as we're told.
There you go ignoring the point again.
The point is not that there are bricks, it is that all objects have a thermal mass.
Things don't instantly change temperature.
In order to cool down, they need to dissipate heat. That thermal energy needs to leave the object and go somewhere else.
In order to heat up, it needs to absorb thermal energy from somewhere else.
On the moon, there is negligible thermal mass (other than the moon itself). That means there isn't really anywhere for the heat to go. Again, you have already admitted that. And that means that things wont just magically freeze.
The main way to cool things down would be evaporative cooling or radiative cooling.
