"A dream. It's perfect": Helium discovery in northern Minnesota may be biggest ever in North America::For a century, the U.S. Government-owned the largest helium reserve in the country, but the biggest exporters now are in Russia, Qatar and Tanzania. With this new discovery, Minnesota could be joining that list.

Hopefully we stop wasting this limited resource on fucking balloons.

Edit: well this kicked off a fun and respectful conversation. The information I can find from actual scientists says wasting helium on balloons is bad. The balloon lobby says it is just a waste byproduct. The balloon lobby brings nothing of value to the world in terms of plastic or helium use, so I'm going to go with the science opinion on this one.

The helium used for balloons is of low purity.

The shortages you hear about are of pure or near pure helium. The stuff going into the balloons at Tommy's birthday party isn't the same thing used to cool superconductors.

EDIT: And I used to think Reddit was full of ignorant jackasses ...

Balloon helium is 3% helium. So every 33 balloons is one Balloon worth of pure helium. No helium starts off pure. It all gets concentrated/separated to get that way. "Balloon grade" helium can be concentrated just fine and considering that thousands of those balloons are filled every day, it is a lot of wasted helium.

*I had my percentage swapped, it seems. Balloon helium is 97% helium.

balloon helium has some air in it, it's still 90%+ helium, probably

Oh. I had that totally bass akward.

Last time I bought what I thought was a pure balloon of He, I’m pretty sure it had gotten cut with fentanyl.

How high did it get? Asking for errr... science...

[–] [email protected] 17 points 1 year ago (5 children)

What the fuck are you on about? Helium is an element. Doesn’t matter if it’s low purity it’s wasted and then gone. When the high purity stuff is gone we can’t be like “thank god we can purify the low wall quality stuff” when that’s gone too

Using it for balloons is still a waste because that impure helium could be purified for better uses.

[–] [email protected] 16 points 1 year ago (4 children)

No, no it could not.

The stuff used in balloons isn't pure enough to be used for cryogenic purposes, which is what people really want it for.

And before you ask purifying it is really difficult.

[–] [email protected] 8 points 1 year ago (7 children)

Incorrect. It is not found naturally pure, it must be distilled. Balloon helium vs cryogenic helium is like comparing ice distillation vs vapor distillation of liquor. One is cheaper but both are using up a limited resource.

No helium found on earth ever, was pure enough for cryo. Not even close. All helium is found in low concentrations and spun extracted to concentrate and start to purify it. Then there are additional filter methods to finish concentrating it. Removing the hydrogen is about the hardest because it's also abundant and small and light.

But helium used in balloons can absolutely be concentrated and purified.

I don't recommend fucking balloons. The squeaks are annoying and the pops hurt.

[–] [email protected] 18 points 1 year ago

You need more lube.

[–] [email protected] 24 points 1 year ago (5 children)

I think for balloons we should switch back to hydrogen. What could possibly go wrong?

[–] [email protected] 21 points 1 year ago

It would make birthday parties more fun

helium just boils off in MRI/NMR machines, this is the major use of helium i think. if you could recycle that in machines that already are out there, that would solve lots of problems. there are newer systems that do not require cryogens or just require liquid nitrogen which is much cheaper and less energy intensive. these things use closed loop refrigeration, but in turn you need to supply them with power

Thomas Abraham-James, CEO of Pulsar Helium

Oh my god, fuck this. Have we learned nothing? Nationalize that supply right now.

[–] [email protected] 15 points 1 year ago (2 children)

What should we have learned? I'm out of the loop.

That letting capitalists gatekeep access to essential resources is a terrible idea.

[–] [email protected] 12 points 1 year ago

Ah ok. I thought there was something specific about this man or company being evil, like that Massey energy guy is to coal mining.

[–] [email protected] 34 points 1 year ago

Don't waste your limited resources on party balloons

[–] [email protected] 39 points 1 year ago (4 children)

Somewhere in that mine we're gonna have a bunch of iron miners getting squeaky voices and start sounding like the seven dwarfs.

If there's so much helium inside the earth, then why doesn't the earth float away?

This is actually incredibly good news

[–] [email protected] 10 points 1 year ago (5 children)

Not really, because we're still pissing away invaluable helium because of capitalism...

If we keep doing that, it doesn't really matter how much we find.

We need to stop wasting it first, then finding huge supplies is a good thing. As long as we're not dumb enough to start wasting it again.

[–] [email protected] 19 points 1 year ago (7 children)

Ah yes, we're wasting helium, so finding more isn't a good thing. Of course. 🙄

How do you find helium? Did everyone suddenly start talking like chipmonks?

[–] [email protected] 12 points 1 year ago

[off topic]

"The Guns Above" by Robyn Bennis. What if Napoleonic armies had an unlimited supply of helium? The author does a great job of describing 1800's airships and their tactics.

Fun book.

This is the best summary I could come up with:


MINNEAPOLIS — Scientists and researchers are celebrating what they call a "dream" discovery after an exploratory drill confirmed a high concentration of helium buried deep in Minnesota's Iron Range.

Prior to arriving in Minnesota, Abraham-James was working in Tanzania, where another helium discovery was made, but at half the concentration as found in the Iron Range.

The inert gas is likely known by most consumers for filling balloons and blimps, but it's actually one of the most sought-after commodities in the world because of its versatility; as a liquid, helium is among the most effective and safest coolants around.

Dr. Grant Larson, a radiologist at Hennepin Healthcare, said the health system's four MRI machines rely on helium to operate.

"We're aware that it could potentially render us vulnerable to not being able to provide access to our patients," Dr. Larson told CBS News Minnesota.

"It's not just about drilling one hole, but now proving up the geological models, being able to get some really good data that wasn't captured in the original discovery," he explained.
