i can already tell that all of these "advanced" designs will be absolutely annihalated when aeronautics comes out and the min-maxing sweats get their hands on it. the most efficient airship design will probably be like a netherite brick with interior propellers.
Wonderful job with all those airships. I'm hooked and started making some of my own. However, I couldn't find anywhere how do you refuel the ship? How do you pump water in and how you pump or convey the fuel. I'm still not versed in contraptions, is there a way to create retractable conveyor belts or something like that? Thanks and I'd really appreciate an honest answer.
