Couple that with the centrifuge idea someone else had.

And you separate the gasses how? "Greg D. Moore (Strider)" wrote in message ... "Explorer8939" wrote in message om... 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? |

We are now entering the realm of "things astronauts can't easily cobble together from existing items on ISS." :-) besides with time so short what other essentiakl item do you cut to build this? .. .. End the dangerous wasteful shuttle now before it kills any more astronauts.... |

I know I know. Nothing is easy in space except floating! :-)

We are now entering the realm of "things astronauts can't easily cobble together from existing items on ISS." :-) Obtain some PTFE or similar tubing. (alternatively, are there general purpose tools, such as drills/bits/screwdrivers on the shuttle? If so, you could use an aluminium block heated.) Now, wrap this round a heater heated to 130C (?). Connect one end to a bag of urine, with weight on top (or elastic band). On other end, put nozzle. Now, this produces a fine spray of boiling urine (at 100C (or a bit lower, is ISS at sea level?)) from which a fraction of the water immediately boils due to the superheat. Around the spray goes a can with air blowing over the outside, and a towel is placed so that it can draw off the water condensing on the can from the rim of the can. It will need squeezed out quite often. Could you assemble this over the toilet, which might deal OK with the result. |
