Weight and Bose Einstein Condesate questions

Here is something that got me thinking, and i hope someone more knowledgeable can think about it, answer it.

Imagine that in the future we could cool gases down to near 0K in a practical transportable matter. We could use the Bose - Einstein condensate state of matter to compress the gas to a point where it would take a fraction of the volume needed now. Would be great for space ships if the required system to keep the gas in a BEC state of matter is lighter in weight than a normal compressed tank with the same volume of gas.

If i understand correctly, the weight of a BEC of atoms does not change, only the volume yes ?
Since the atoms are occupying the same space, the volume would be less, but the total mass remains the same right ?

Would it ever be possible to slowly pick up the needed atoms and heat them up to a temperature that is usable ?

Can theoretically a BEC state be created with billions and billions of atoms and not just a few ?

Phase doesn't change the mass of an object. Volume barely matters in space since there's almost no resistance. Keeping an object colder than space requires energy...and energy is highly limited once you get far enough from a star. Really the two variables that are probably most important for deep space travel are mass and energy, neither of which the BEC has any positive effect on.

(Weight has nothing to do with any of this, hence why I ignored it.)
