A high-level Mechanical <l:6,66>Advance<e>, Nano-Assembly exceeds old limitations, synthesizing new materials atom by atom. In special <l:2,55>Nanite Factories<e> built only in space, assembly costs plummet: Rush Buy costs equal costs of production. With the <l:3,46>Nanopedia<e>, which doubles the effects of all <l:6,119>specialists<e>, Nano-Assembly offers a new hope for the future. Nano-Assembly also allows space cities to build <l:8,15>Advanced Assembly Modules<e> to provide even more <l:6,93>production<e> power. Finally, introducing clean methods of production lessens the <l:6,91>pollution<e> throughout your Civilization considerably.
