You know what, since I made this topic, I have had a completely different idea for airship inflation instead of this one. You see, I'm no longer interested in building vacuum airships, but hydrogen airships with their density reduced. You know what, since I made this topic, I have had a completely different idea for airship inflation instead of this one. You see, I'm no longer interested in building vacuum airships, but hydrogen airships with their density reduced. I would rather just have hydrogen-based inflation, with the hydrogen evacuated in an inflatable skin only enough that it's danger is greatly reduced, since in a puncture air will seep in, rather than the hydrogen bursting out. At the same time the airship no longer has to deal with hydrogen leakage, a significant bonus. With this idea one can return to using large airships and even the Zeppelin military ship without making significant changes to them, besides reducing the weight by kiloliters of hydrogen and a heavy aluminum shell. Now, what would be the limitations to that? Please do share.

I wasn't talking about the airship, I was talking about the speculative honeycomb LDH technology. It can be used to make lighter weight rigid parts I said. So rather than having to lift all the weight of the rigid parts of the airship (like the machinic and nonsensitive parts), they will be inherently lighter in weight and thus the airship can have more lift.

I know now that making a full on vacuum airship is unfeasible for it's compressive properties. So why not just make a rigid airship that is evacuated enough that the hydrogen is no longer significantly dangerous to it's surroundings, using say 25-30% density of neutral hydrogen? What's the weakest compressive material I cod use for that? Could I, in practice make any rigid, non-curved part out of a honeycomb-like structure of LDH-cells? This could be revolutionary in creating lighter weight rigid parts where volume isn't too sensitive and lighter weight is an advantage. Can someone give me a formula(and tell me all the dependent/constant variables) to get real values on this and fact out the feasibility myself? Thanks.

@lemur Provided you need to use rigid materials anyway, instead of using a complete vacuum(which you must know requires too much by now) why not just make a hydrogen one that is evacuated to the point that the hydrogen is no longer significantly dangerous, can that be done? I don't know for sure but something like that should be possible. Say a 25% hydrogen balloon. Unless your specific application doesn't allow that? I'm about to ask my own question that's similarly related to that, so it's good to know some background information before then.
