In Pisa, Italy, mad genius Enrico Dini is building sandcastles on the moon. His giant 3-D printer is the first of its kind with the potential to print whole buildings, and it makes them out of solid rock, cutting down a thousand-year-long process into a few minutes. It uses sand, but someday it’ll use moon dust. … As part of the European Space Agency’s Aurora program, he’s talking with La Scuola Normale Superiore, Alta Space, and Norman Foster to modify D-Shape to build with moon dust. Voila: instant moonbase. (via Fast Company)
