When we go to Mars we need to take the industrial revolution with us...a scaled down version of industry that can deliver a range of products.

With that in mind, this demonstration of what can be achieved with scaled down machines and simple solar power, is very interesting:

http://www.popsci.com/technology/article/2011-06/video-3d-printing-glass-using-sand-and-solar-power

From the Popsci article:

"Markus Kayser’s Solar Sinter Project takes the desert’s two most abundant resources, sunlight and sand and puts them to work manufacturing glass objects. Kayser loads the sand into a solar-powered 3-D printer where it serves as the raw material for glass.

In a process that’s fascinating to watch, concentrated sunlight replaces the laser typically found in 3D printers, melting sand (instead of resin) in patterns to form an abstract sculpture or, more usefully, a bowl."


I think this type of machine - scaled down, marrying robotic technology with human oversight  -  is just the sort of thing the first humans on Mars need to bring with them. Although the amount of solar radiation available on Mars is nowhere the intensity of the Sahara, reflectors could be used to concentrate the solar power and achieve furnace-like temperatures.  The production of the bowl at the end of the video shows that useful objects can be produced.

Of course, I am not suggesting that the Mars pioneers would take exactly this type of machine, but it shows that small scale smelting could take place and that a variety of objects to be used in the kitchen, in farm areas, or in exploration could be produced.

I think on Mars the pioneers would probably take with them small furnaces to use in conjunction with solar power.

  1. Hi Louis, it's GW from the NewMars forums, also a follower of yours on your blog here.

    For terraforming or colonization purposes, I have run across a big difference between minimum adult human life support vs life support when pregnancy is involved.

    Minimal life support is 180-190 mm Hg pure O2, while life support to avoid deadly problems in pregnancy is apparently 1 full atmosphere of Earth-normal air. That seriously impacts what we permanently live in, on Mars.

    I'm going to present a paper at the Mars Society convention in Colorado this August 2013. It's about a really oddball heat shield material that Mars landers might use, stuff I last built about 3.5 decades ago.

    I made this stuff for a completely-different application, and I am the only person who ever built this stuff.

    It should raise some eyebrows. Wonder if you might be attending?

  2. Hi GW,

    Sadly I shan't be there. But if you want to preview your paper here or write about it afterwards here of course you are very welcome to do so.

    Pregnancy is going to be a big issue for full human colonisation of Mars. It's not just the atmosphere, it's also the gravity that's important - or so I've read. For successful pregnancy it might be a case of women giving birth in Mars orbit in special 1G habitats .
