The Space Toilet
-
0:01 - 0:02When you go to the bathroom on earth,
-
0:02 - 0:05your're relying on gravity...pretty, pretty heavily
-
0:05 - 0:09Imagine if you're half way done and somebody shut off gravity
-
0:09 - 0:13It'd be a mess and you'd float of the toilet
-
0:13 - 0:17So, when we designed our space toilet
-
0:17 - 0:19first to a seat belt on it, to hold you down
-
0:19 - 0:27and then, we decided to separate solids and liquids because it is easier to store that way
-
0:27 - 0:32So, we just have tube that you pie into, and have air pulled to the tube
-
0:32 - 0:34so it's not a big deal
-
0:34 - 0:35For the women, there's a cup that fits-up against them,
-
0:35 - 0:38For the guy , it's just a little tunnel, you just pie into the stupid
-
0:38 - 0:40it goes into a sewage tank
-
0:40 - 0:45But the solids that come out of your body ,
-
0:45 - 0:47that's a harder problem to solve
-
0:47 - 0:49And it's an important medical one,
-
0:49 - 0:50because on Earth everything falls in the floor
-
0:50 - 0:52But in space it's gonna float around
-
0:52 - 0:58So it'll really make you sick
-
0:58 - 1:01If you re-ingest something that came out of your body
-
1:01 - 1:03it will really make you sick
-
1:03 - 1:04And we can't afford to get that sick
-
1:04 - 1:06So we designed a toilet that,
-
1:06 - 1:08instead of gravity pulling everything into the toilet,
-
1:08 - 1:10it has air flow
-
1:10 - 1:12There's air pulled down into the toilet
-
1:12 - 1:13-- Sort of windy when you're sitting there
-
1:13 - 1:15But it pulls everything out of your body
-
1:15 - 1:17Everything that comes out of your body
-
1:17 - 1:19gets pulled down into the toilet by the air
-
1:19 - 1:23and then in the storage tank we just expose that to the vaccum of space ,
-
1:23 - 1:26so it basically just freeze-dries everything
-
1:26 - 1:27So it killes all the bacteria
-
1:27 - 1:29so there's no smell
-
1:29 - 1:31And then we store it
-
1:31 - 1:34And then when we have a whole bunch if stored
-
1:34 - 1:36we put in a little unmanned supply ship
-
1:36 - 1:39and then we undock it and then it burns up in the atmosphere
-
1:39 - 1:46So the next time you see a beautiful shooting star going across the sky
-
1:46 - 1:48that's what it might be
