In Fires Over Omac an ore called “coltane” is referenced as fuel for Hammer ships. In Bloodstained Stars the author mentions refuelling at gas giants and tankers. Does anybody know what’s “canon” for this? Doesn’t matter to me either way, I just want to understand it.
If coltane’s the real deal, does anybody know what it is? Apparently there’s a real ore called coltan (tantalum ore or some such) but I don’t find anything called coltane. Is it just handwavium or is it based on a real substance? What are its properties? Is it volatile? Inert? Stuff like that.
