Washing clothes: As e.g. NASA astronaut Karen Nyberg, and CSA astronaut Chris Hadfield demonstrated in a video, respectively, astronauts can wash their hair and brush their teeth in microgravity with little effort.

Only maybe more of the precious water can be saved by developing alternative washing techniques; AIUI from my practice, for washing clothes the clothes only have to soak up water, then the washing agent has to dissolve in the water to get the dirt and sweat out of the threads, and then the soapy, dirty water has to be removed. Certainly this can be done in space. But probably the best way to solve this problem would be using special threads in the clothes that cannot get dirty or sweaty in the first place.

But I bet SpaceX is working on the other aspects, too. If they had worked on the other aspects, they would not be presuing it, unless they are going after Gov R&D dollars, our tax dollars. it is a marketing pitch to capture government funds which float and pay for his other companies, Tesla and SolarCity. Nonsense. FUD. wrong, Musk runs those two companies on Government funding, and they are both in the red. Try to keep up. It does not address RADIATION at all, Musk addresses the radiation issue in the Q&A section after the talk. Basically he says that it is not a problem with a little shielding. Wrong, you can only use 18 feet of water surrounding the astronoughts., this is well known. Lead ? how many pounds ? and what about secondary radiation from the Lead? nor food, nor water, That is not SpaceX’s main department, but that of other players NASA is already working on self-sustaining environments. For example, the air conditioning and sanitation systems on the ISS is amazing, there are chemical toilets on the planet already (the “Burning Man” guy asking about the prospect of “****ty Mars” in the Q&A section obviously did not know that), and they are successfully growing “space salad” on the ISS: enough salad for one byte a month ? nor how to wash clothes in space. Really, who needs clothes in a climate controlled spacecraft? A climate-controlled spacecraft that could be punctured by a micrometeorite any moment. Besides, astronauts/passengers are people, too, with a natural pudency. Washing clothes: As e.g. NASA astronaut Karen Nyberg, and CSA astronaut Chris Hadfield demonstrated in a video, respectively, astronauts can wash their hair and brush their teeth in microgravity with little effort. the reason was to minimize the seriousiness of the problem of washing clothes in space. they do not do it now for many reasons. [1][2] I can see no great difficulty washing clothes in space in a washing machine designed for microgravity once you have it there (I think the main problem is designing it and bringing it there). so you have soap, water, agitator, that part is easy. Now seperate the water from the dirt, the soap, and clothes. (think about this) how much energy does it take? can you seperate the dirt from the soap, what gets discarded ? Only maybe more of the precious water can be saved by developing alternative washing techniques; AIUI from my practice, for washing clothes the clothes only have to soak up water, then the washing agent has to dissolve in the water to get the dirt and sweat out of the threads, and then the soapy, dirty water has to be removed. Certainly this can be done in space. instead of skipping the details, list it on out... did you know ISS all the clothes are washed on Earth, new clothes are shuttled up. But probably the best way to solve this problem would be using special threads in the clothes that cannot get dirty or sweaty in the first place. [3] but that is what the clothes are there for, to capture that stuff. |
