This mod provides a source of artifacts for players on peaceful modes, by adding a new set of recipes and intermediate components for crafting alien artifacts from stone, copper and iron:

1. Combine stone, copper, iron and sulfuric acid in a chemical plant to produce rare earth
2. Smelt rare earth in a furnace to produce superconductors
3. Combine superconductors with plastic in an assembler to create superconducting wires
4. Combine superconducting wires with processing units in an assembler to create alien artifacts

I recommend combining this mod with Artifact Retexture to retexture alien artifacts as "advanced processing units"
