Given its scarcity, helium should be more expensive, to the point where filling party balloons with it is decadent profligacy.

[-] el_abuelo@programming.dev 29 points 2 months ago

I mean it is expensive, it's just the amount required for a balloon is insignificant and thus seems cheap.

As a diver who uses helium I can tell you it is, compared to air, so much more expensive they actually charge me for it (rather than just rolled into the cost of a dive) - to the sum of about $300 a dive - depending on depth.

[-] FeatherConstrictor@sh.itjust.works 10 points 2 months ago

What is helium used for when diving?

[-] el_abuelo@programming.dev 39 points 2 months ago* (last edited 2 months ago)

Reducing the amount of narcotic gases in your mix so you don't act like a drunk idiot when in a life threatening situation.

Those narcotic gases are nitrogen and oxygen (although there's only so little oxygen you can have....and also only so much!)

Edit: extra info: oxygen and nitrogen are narcotic at depth, nitrogen is better understood and so often we talk about nitrogen narcosis, which tends to start hitting people after about 30m, but each person reacts different and to different degrees at different deaths. I personally notice it at about 50m or so. If I was more relaxed while diving it'd probably hit me sooner.

[-] tektite@slrpnk.net 7 points 2 months ago

and to different degrees at different deaths.

Was that supposed to say depths?

[-] FeatherConstrictor@sh.itjust.works 5 points 2 months ago
[-] el_abuelo@programming.dev 6 points 2 months ago

Most welcome! I can talk endlessly about diving so welcome the question.

I added an edit with some more information incase you're more curious.

We should go back to filling them with hydrogen.

[-] FlyingSquid@lemmy.world 43 points 2 months ago

What could go wrong?

I mean other than that...

[-] shadowedcross@sh.itjust.works 28 points 2 months ago

Would make for more exciting birthday parties.

[-] Someonelol@lemmy.dbzer0.com 22 points 2 months ago

The alternative is to use extremely limited quantities of gas crucial for MRIs, chip making, metallurgy, and a few other high tech applications. But hey, pretty balloons.

[-] RedEyeFlightControl@lemmy.world 11 points 2 months ago

Only a matter of time before they can't get any because we wasted such a limited resource on vanity instead of the pursuit of science.

[-] el_abuelo@programming.dev 4 points 2 months ago

Perspective my dude. An insignificant small amount is spent on vanity.

I've used more helium on a single dive than I've ever used in balloons in my entire life.

When I was a kid, Dave Berry had a column where he made fun of the US Strategic Helium Reserve. This taught me an important lesson: when people make fun of what seems like government waste, 75% of the time it turns out to be really important. Not always, but you should look into it more.

Am I missing a joke? Airships used hydrogen gas

[-] Blaster_M@lemmy.world 6 points 2 months ago

Specific airships made by a specific country that had no access to helium...

[-] Revan343@lemmy.ca 5 points 2 months ago

Not exclusively, hydrogen being lighter and cheaper meant it was still sometimes used when helium could have been.

When I was in school decades ago, my science teacher brought in a big balloon filled with hydrogen and lit the string on fire without telling us that it was filled with hydrogen.

I could feel the explosion in my bones. It was neat.

I’m not sure you could do that in schools today.

[-] julysfire@lemmy.world 31 points 2 months ago

There will absolutely still be a customer that takes a balloon from behind the sign and asks for it to be filled up in the store.

[-] Beldarofremulak@lemmy.world 20 points 2 months ago

They will demand it or else poor Kayla'lin 'da Leeigh Lynn Lee's princess party will be ruined.

I think you just summoned an Elder God.

The Eldritch God of over eccentric suburban moms is somehow more terrifying than anything Lovecraft came up with.

Fuck! How am I going to refuel this fusion reactor I brought back from the future? You can't have shit these days.

[-] FlyingSquid@lemmy.world 11 points 2 months ago

May I suggest food waste from someone's garbage can? I hear that works.

Just use hot air. Lots of that to go around.

[-] FlyingSquid@lemmy.world 15 points 2 months ago

I'm afraid it's already in use by politicians.

I could have sworn they were hot air generators

It's endlessly recycled.

[-] Cagi@lemmy.ca 17 points 2 months ago* (last edited 2 months ago)

Mylar balloons should be outlawed. They get sent free and land on power lines WAY too often. Over a thousand mylar balloon caused power outages are recorded in just Southern California alone in a typical year. The cost of repairing the damage might even exceed the revenue of mylar balloon sales.

[-] Abnorc@lemm.ee 15 points 2 months ago

I want a balloon full of uranium hexafluoride.

I really wonder what power plants will do with the helium once they get fusion working. Maybe a balloon business on the side isn't such a bad idea.

[-] subtext@lemmy.world 12 points 2 months ago

I mean too much Helium isn’t a problem. It’s one of the few (only?) elements that will just disappear if you don’t do anything with it.

It’s light enough that it rises to the very tip top of the earth’s atmosphere and is then stripped away by solar radiation. That’s why is a depleting natural resource, not because it’s burned or used or anything, but because it just escapes.

In a perfect world stick it in a secondary reactor and make lithium. But that's obviously even further off than hydrogen fusion.

The amount of helium produced is truly miniscule, in the order of a few cubic centimeters. They'll just pump it into the ground somewhere, assuming we ever get fusion working

Good thing I finally finished voice training and no longer need Helium to pass 👍

Don't you mean "outlaw α-decay" instead?
