地球矿物将月球殖民者最想念?

在我的科学小说,月球殖民者需要收集一些罕见的或没有返回地球矿物(s)在理想的情况下,他们可能来自海水。矿物可能是……?

感觉就像一个space-ex问题我想了不少可能错过在我的帖子里,但这是一个有趣的问题,所以:月球没有大气的最大问题。其他问题没有从紫外线保护,免受宇宙射线和非常好,小和参差不齐的月球尘埃。烦人的东西,进入一切。从地球到月球是巨大的能源密集型和昂贵的,所以尽可能地,无论从月球可以获得,将和尽可能少的会飞离地球。基本像水、呼吸空气、真空密封的生活空间,所以他们不需要穿西装,压力土壤种植粮食和机械制造的东西(是没有意义的生活在月球上,它应该被用于采矿和建筑材料)。一些制造业将更容易在月球的低重力的情况,与地球不同,太空电梯是非常难以建立的,可以从月球建造太空电梯,以方便和廉价的发射。我认为月球上的能源问题是可以解决的,大概是通过太阳能电池板。可能由核,虽然这需要大量的设备。太阳能可能容易大规模生产。然后你需要电池,重。 All that would probably be built on the Moon which would take time, but cheaper than sending material from Earth. Some items they might be short on. 1) Nitrogen. Nitrogen is useful for fertilizer and it's useful to breathing. Breathing pure oxygen is unhealthy (or so I've heard). It may also be useful for some kinds of rocket fuel (I think I read that somewhere). There's not much nitrogen on the moon. (Mars has the same problem). 2) hydrocarbons. The Moon is dusty - really fine teeny tiny very annoying dust particles that get into everything. Oil keeps stuff lubricated and oil makes a good sealant. When (if) a colony is set up on the moon, they're going to want oil for a lubricant, and they'll want to manufacture rubber. There's no oil deposits below the surface of the moon because there was never plant or sea life that got buried and turned into oil or coal over time. There's very little carbon on the moon, no CO2, very little carbonate rock (er, I think). I think, those are the big two, Carbon and Nitrogen. 3) Lithium. This one I'm torn on. Used for batteries, it's lower weight than Lead-acid batteries, but the low gravity of the Moon, lead-acid might not be a problem. You can't burn fuel without oxygen in the atmosphere, so that leaves batteries or nuclear powered equipment. 4) Water, and I know that there's a report that there's a billion tons of water on the Moon and that may be true, but it's underground. There's only a little water on the surface in craters that's easy to access. Water would be a valuable resource on the Moon, not to be taken lightly. There's probably a dozen others that I'm not smart enough to know about and there's plenty of Carbon and nitrogen and water on comets and asteroids, (especially comets), so, it's not an unworkable problem. Capturing a small comet, harvesting it, while keeping it shaded from the sun, changing it's orbit - not easy. All the ins and outs of space colonization make my head hurt. It won't be easy.

\ begingroup美元优秀,userLTK !你真的认为这,我很欣赏你的想法。问题是完善的、自给自足的殖民地(使用充足的水和持续的阳光在两极)但就是只有地球能够提供他们需要的东西。这本书将是续集母亲月球——amazon . co . uk / Mother-Moon-Bob-Goddard-ebook / dp / B018W4GFRM / re ? = geolinker-21标签 \ endgroup美元

\ begingroup美元碳氢化合物实际上是不困难的生产如果你有二氧化碳(或C和O2),水,营养物质(如氮、磷、年代和微量)和能源(显然你需要所有这些支持生命在月球上)。你开始与藻类和生物质合成。这项技术江南登录网址app下载已经存在但目前地球上没有竞争力,因为石油是如此便宜。 \ endgroup美元

\ begingroup美元对藻类养殖@Roland + 1。你是对的。我没有考虑农业或藻类在我的回答,对月球生存和农业显然是至关重要的。但农业需要二氧化碳和月亮没有太多二氧化碳。在这方面,火星是容易,但捕捉小行星或彗星可能不是那么困难和供应所需的二氧化碳和氮气。有很多技术方面的问题,它就变得相当复杂。 \ endgroup美元
