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.


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






- 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.
