energy to matter building

[Deantwo]

well i did i like having each planet making metals

All worlds have ore, so you already can. ^^;

If worlds don't have unique resources, resources only found there or some that aren't found there, then there is no reason to colonize. So really don't see the point of this being a building.

But I still do like the idea of it being a spacecraft manufacturing module. Maybe using some energy and a little bit of raw materials, to make basic components and tools for emergency repairs.
