Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Air ships should make a comeback Throw some solar panels on for electricity

because hydrogen is famously inert and helium is abundant?

[–] Vikthor@piefed.world 9 points 5 hours ago (1 children)

Jet fuel isn't exactly inert either and we now have another 90 years of advances in technology since the Hindenburg.

[–] Buffalox@lemmy.world 5 points 5 hours ago

Hydrogen is a 100 times harder to contain than jet fuel.

Or environmentally friendly if leaked. And leaks will happen.

I am somewhat confident that we could get a reliable H air ship, to be fair.

That’s why you put a vacuum in there. It’s made of nothing, so it doesn’t react, and there’s plenty of it in the universe. Besides, it’s also lighter than anything else you could throw in there.

If there is ever a tiny hole you go from a small hydrogen leak (dangerous but repairable) to a collapse of the entire airship and instantly falling to the ground

No risk, no reward. You wanna fly the coolest airship or not.

[–] arandomthought@sh.itjust.works 7 points 4 hours ago (1 children)

Perfect. Now you only have to find a way to contain that vacuum that doesn't involve thick, heavy walls and we're good to go!

[–] RedGreenBlue@lemmy.zip 4 points 2 hours ago (1 children)

Fantastium fibers should do it.

You can also use unobtanium plates with adamantium rivets if you want to make it look cooler.
