| Oct 11, 2016 at 23:21 | comment | added | Schwern | That's really cool! But it's a 10 meter hull. An ark needs to be larger than a supertanker at 300+ meters. It gets worse. Because of the cube-square law you can't just scale things up linearly. If you double the length you quadruple the weight, and quadruple the needed strength. So... 0) Using a technology still in prototyping 1) design and build the largest 3D printer in the world by a factor of 10 2) build an enormous hull shell for it to print onto 3) print the hull 4) wait for it to cure 5) hope it doesn't collapse because of the cube-square law. | |
