Default Water crisis at ISS, a stupid suggestion

There is a lack of water at ISS, mostly because there's no urine
processor on board. There is a water condensate collector, which is
helping to reclaim some water and stretch the limited supply.
Inquiring minds want to know: couldn't the crew just somehow boil some
urine, and let the condensate collector capture the resulting water
vapor? This water could be used to supply the Elektron and other
systems that can use technical water.

Didn't the russians have a urine processor on Mir ? (as I recall, they didn't
use for for human consumption, but it was good enough for the water processor
that feed water to elektron.

Was this the case ? If so, why was this not installed on Alpha ?

ahh no offense would you like to sit around in a room with a boiling pot of
urine water?

End the dangerous wasteful shuttle now before it kills any more astronauts....

with the shuttles excess water dump they probably didnt feel it necessary. no
doubt dropped during budget cuts........

Just a quick question. How would you go about boiling an open container of
water in zero-g?

IIRC the figuring was that since the Shuttle almost always has an
excess of water, that excess could be used.

It wouldn't be an open container. Those aren't allowed in Space :-).

Now a vessel under pressure...

- Strip the ends off a lamp cord.

- Connect exposed ends of cord to steel wool, heavy gauge.

- Loosen potful of water to center of room, let equalize to medium sized
drop(let). (Need a new name for a drop of water the size of half a cubic
foot or so in volume.)

- Insert the electrical device into the drop and let the water coalesce
around it until equilibrium has been achieved.

- Plug in end of lamp cord to wall socket.

Easy.

Of course there is the low tech way that involves a big magnifying
glass, but you need to work out orbital issues, as well as craft
rotation on the long axis and positioning yourself near a porthole.

And you separate the gasses how?
