Helium isn’t exactly an abundant resource either, is it? I’m all for a future with a sky dotted with airships, but how could you possibly scale this up?

I thought it was an abundant resource just not here, awkward places like the moon and sun.

Man I can't wait till we're able to harvest helium from the Sun! That means that we made to the big leagues.

Dyson sphere or ring world which do like better?

Dyson Swarm. Makes more sense to me.

[-] Maalus@lemmy.world 2 points 2 years ago

Yeah, it's expensive as shit.

Hydrogen has about half the density of helium. The fire risk is notoriously unpopular, however.

Wide-spread adoption of airships would almost certainly have to use hydrogen.
