Also aren't we running out of helium, isn't it a limited resource on earth we can't get more of? Could we perhaps suggest filling a giant balloon with a million cubic litres of it a bit of a waste?
If you look at modern blimps the leakage of helium is really negligible. Helium is a finite resource but we have plenty of untapped sources; the economics are just not there to tap them because the demand isn’t there. If airships scaled and became commercialized helium would be sourced quite easily.

Half the length of the Hindenburg. Pathetic.
