An evening pause: How things will be built and manufactured in the future, on Earth and in space, though in space they probably won’t use concrete.

    Actually they might use concrete. McDonnel Douglas and the Shimizu corporation worked up some lunar base ideas ( http://www.shimz.co.jp/english/theme/dream/moonbase.html ), and did testing on a new concept to cast concrete made out of lunar soil in a vacume. Worked great and the Lunar soil made the best concrete they ever saw. [Course the moons pretty dry, but water is common in near Earth space.]

    I wonder if you could use liquid metal? Say melt the highly pure nickle Iron of a asteroid, and pump it outto lay it up to form a station or colony platform.
