- New idea for inflating airship with LDH(at most 30%hydrogen)

What is the formula for finding out the minimum shell compressive strength?

Beyond possible, is LDH "inflation" for a large airship practical? What would be limitations or things to consider?

Would making regular machined parts out of LDH honeycomb be possible&practical? If so, it could be revolutionary.

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 could use for that?

Could I, in practice make any rigid part out of a honeycomb-like structure of LDH-cells? This could be revolutionary in creating lighter weight rigid parts provided volume isn't too sensitive and lighter weight is an advantage. And of course, individual parts can be made out of their own honeycomb, with variation in shape, dimensions, hydrogen densities and what not depending on their allowances and needs.

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.
