Thanks, Eddi, a much better description than I would have come up with for deuterium.
Colonists (PASS) - just renamed passengers. In addition to intercity transport, they can also be sourced from colony landers where they were cryogenically frozen.
Xeno-Diatomite (DIAT) - aka, Diatomaceous Soil. The sugar graphic is perfect for this. Basically, the alien version of that stuff I put in my pool filter. Its formed from algae and other micro sea creatures. In my sci-fi version, its the same idea, but there's some sort of alien property in it that makes it great for making a ceramic that acts like a lightweight metal. Realistic? No, but neither is red water or Martian trees
Colony Supplies (SUPP) - Basically goods. Nothing fancy. Can represent small items (in crates), food, large manufactured stuff.
Ceramic Alloy (ALOY) - Sort of a metallic ceramic. Super light weight, good heat properties, etc. Great for manufacturing. I figured the steel graphics would work best.
Chemicals (CHEM) - I had a few versions of what would come from the refinery - hydrogen, oxygen, water... eventually I just simplified to deuterium and a generic "chemicals."
Xeno-wood (WOOD) - "Martian" trees
Xeno-flora Lumber (LUMB) - I don't actually like this one, but I wasn't sure what to do with it. I almost changed it to wood pulp or something similar since it gets received by a bio-plastic extractor to generate items for the factory.
Bio-Plastic (PLST) - plastic from plant materials. Given the "bio" prefix to make it sound fancy.
Hydro-chemical Slurry (HYCH) - Basically just a sloshy mix of hydrocarbons, water, and whatever else is in the ground that gets pulled out in mostly (thick) liquid form. No idea what it would look like, but I bet the smell would be impressive
Mail (MAIL) - yup.
I'm certainly open to suggestions!
