So we know that we'll mine resources of various kinds... and build things... and some of those things will be ships which need fuel.
Will the materials be ores that need to be refined at some sort of refinery to be made into the finished fine materials used for building... or into the fuel or fuels used by various ships engines?
I think it'd add another layer to the economy if miners sold to refineries ... and refineries had to be large constructs... with storage for their product which could then be sold to builders and explorers and shippers.
Also has any thought been given to power generation to power lights... or the hypothetical refinery?
