First off amazing game, that needs to be said. Secondly apologies if this was already suggested.
I recognize and applaud the decision to not allow industry on ships (why build a static construct when you can have a mobile factory) but I'd like to suggest introducing a mobile/dynamic fuel industry element and the same for a mobile scrap industry element that can be placed on dynamic cores. For balance you could restrict or reduce the output compared to its static counter-part, in the form of longer craft time/smaller output or decreased efficency. You could also limit the number of mobile elements by core size, until a suitable power system is in the game. From my point of view, it's benefits would be three fold; greater independence when exploring space/getting caught out less often out of fuel, something to do/manage during long space flights (I hope DU will get much bigger in the near future) and finally I think its fitting with sci-fi genre (deep space ships need to be able to autonomously refuel).
