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

[-] el_abuelo@programming.dev 26 points 3 weeks 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.

What is helium used for when diving?

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 3 weeks ago

and to different degrees at different deaths.

Was that supposed to say depths?

[-] el_abuelo@programming.dev 5 points 3 weeks 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.

Privatization seems like a really bad idea to me. Helium is non-renewable resource. Privatization is about being 'efficient' at maximising profits. Do you think the people / companies that own the helium reserves are going to be interested in keeping helium available for centuries in the future? I'd say probably not.

For a profit based company, the only motivation to preserve the helium for future use is that maybe it will be worth a lot more money in the future. But there are two big problems with that. Firstly, the timescale is likely to be too long for the profit to be of interest. And secondly, the main reason the price would go up is scarcity; and that scarcity will come sooner if the helium is wasted in the short term. (Unless one company actually has a monopoly on helium, in which case they can create artificial scarcity by just not selling it. But that would obviously be bad for other reasons.)

[-] roguetrick@lemmy.world 4 points 3 weeks ago* (last edited 3 weeks ago)

The thing with helium though is that it's already privatized. The geologic formations that trap helium from uranium and thorium decay are the exact formations that trap fossil fuels, particularly natural gas. Whether it's worth it to capture that helium is purely market driven by private interests. Most of it is just off gassed into space instead of separated. All that government production has amounted to is making helium cheap enough to put in balloons and use on wasteful cryo applications with no recovery mechanism like it was subsidized, making separating it from natural gas uneconomical. Increasing the price would decrease the monumental waste we already do.

We should go back to filling them with hydrogen.

[-] FlyingSquid@lemmy.world 40 points 3 weeks ago

What could go wrong?

I mean other than that...

[-] shadowedcross@sh.itjust.works 26 points 3 weeks ago

Would make for more exciting birthday parties.

[-] Someonelol@lemmy.dbzer0.com 20 points 3 weeks 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 3 weeks 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 3 weeks 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 3 weeks ago

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

[-] Revan343@lemmy.ca 4 points 3 weeks ago

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

[-] Rai@lemmy.dbzer0.com 6 points 3 weeks ago

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 27 points 3 weeks 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 18 points 3 weeks ago

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

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 14 points 3 weeks ago

I want a balloon full of uranium hexafluoride.

[-] bjoern_tantau@swg-empire.de 10 points 3 weeks ago

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 11 points 3 weeks 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
