So I'm in the throes of a duranium crunch - Earth is out, I have mines, automines, and asteroid miners wherever I can in Sol (but that's not much), and the other solar system I'm exploiting has very little duranium. Since I need duranium to build everything, I can't seem to escape the crunch. I can't build more mines or automines, ships to explore for more, or even infrastructure so I can get more colonists to work the mines on Titan. Any suggestions on the most efficient way to use the duranium I have, and eventually how to escape the crunch?
