As a physicist, I really appreciated this presentation, and I think you got it all just about right. Unfortunately, most people - and, in particular, most legislators - think helium is just a joke, used for party balloons. It's not. Helium is a critical non-renewable resource that is vital for many industries, and we have suffered from shortages. We need to hoard the stuff and re-fill the national helium reserve.

@@bearcubdaycare Sorry for the delayed response, but I just saw your comment. I have not used helium, but I have a colleague whose research at low temperatures was made so expensive that he spent a few hundred thousand dollars to build a helium-recycling facility. The huge price increase has cause a big hit to this branch of physics.

I work in vacuum carburization (heat treating to increase surface hardness) of vehicle transmission gears for a major auto manufacturer. We actually quench each load with helium at 18 bar (atmosphere pressure at sea level times 18). We reclaim the helium, put it through an O2 scrubber to keep the oxygen out (discharge is H20), and shove it back in our massive helium pressure tanks. Helium is second to only one gas at quickly quenching glowing-hot metal. Hydrogen is the best, but you can guess why no one uses it for that process. The industry is turning to nitrogen quenches. It's basically 80% of what you breathe, and can cheaply be generated in pure form. But it's messier and slower than helium. The quickness of the quench determines part deformation. Slower = bad. Quicker = good. I loved this video, and watched it for the science. But that threat that helium was getting pretty rare has made an irreversible seismic shift in my industry. The price-shock changed industry for decades to come.

For us, this is done by pulsing acetylene gas into the chamber, which then breaks down into carbon and hydrogen at high temps. The carbon is infused into the metal. The quench process is a way to immediately stop the heat treating process.

You know what I really like about your channel? Everything. Liquid helium is used in the whole body superconducting MR magnet’s to keep them in their superconducting state. There are now 3 types of superconducting magnets: Full loss (where the liquid helium boils to gas and is lost to the atmosphere); Zero boiloff, where the cryogenerator keeps the liquid helium at its liquid state and there is no boiloff; and the newest magnet which only uses a small amount of liquid helium in a cycle of convection. This new magnet never looses helium to the atmosphere. The consequence of loosing the liquid helium would be the magnet quenching and loosing its magnetic field. Usually, the magnet isn’t damaged and can be refilled with liquid helium and re-ramped back to field. I’m a professional MR engineer with 36 years of experience with MR systems. The picture of the MR system in your video is the company I work for. Love your channel very much. Please keep up the outstanding work you do. Someday, maybe, we will see you on the History Channel. That would be awesome.

What a wonderfully told story! I work at a particle accelerator and we use helium for cryogenics and leak detection. Several years ago a helium recovery and re-liquefaction plant was installed, and we now recover 90,000 liquid liters a year of helium that used to be vented from experiments. Its a big saving now that it costs about $15 per liter!

Point of contention: Helium, or liquid helium to be exact, in MRI is not used to prevent wear and tear. It is used to create the superconducting environment for the internal wire windings of niobium-titanium (NbTi) which display zero electrical resistance at a temperature of approximately 4 degrees Kelvin, allowing for superconductivity. This means that the electromagnetic high strength field generated by the large current applied to the windings is static and does not need a continual source to remain at field. A complex system of cryogenics and temperature shielding is used to maintain the near-absolute zero temperature, reducing or eliminating liquid helium boiloff. This is my job, to repair and maintain these machines.

This channel never ceases to amaze me in it's quality and content.

I never knew how important and complicated the discovery of Helium was until now. I have to admit I only thought of it as a gas for balloons and blimps too. Thanks for sharing this story. And your right, all good stories have pirates in them.

I learn from my colleagues who still work in the industry, that MRI magnets have become more parsimonious with their once profligate use of Helium. In my twenty-three odd years as an MRI Field Engineer, I must have used hundreds of thousands of litres of LHe - which is not cheap - yet I never actually saw LHe, ever. As HG mentioned, it has the lowest boiling point of any liquid and even with the full 'push pressure' (used when filling a magnet) expelling the liquid up through the dewar stack and through the fill line (essentially a half inch, flexible, stainless steel pipe) actual liquid Helium never comes out of the end of the pipe. Very rarely, droplets of LHe are spat out, but they are always surrounded by a covering of furiously boiling vapour and they vanish after less than a foot. You may wonder why, if He is so valuable, we just blew it out the pipe before filling the magnet? Precooling is the answer. The plumbing all starts out at room temperature (20C or about 300 Kelvin) and must be precooled to close to about 4 Kelvin or -270C, otherwise we would be blowing (relatively) warm gas into the magnet and that, to say the least, is not good. So many people mention the squeaky voice trick. We who used it, would never get close enough to our Helium, because it was so, so cold - freeze your eyeballs cold. Also, our safety rules forbade us from mucking about with it. Helium is a very efficient asphyxiant, because it not only flushes all the oxygen out of your blood that's already in there, it flushes all the CO2 out of your lungs, which is what triggers your 'breathe reflex.' If you play the squeaky voice trick too often or too much, you can die, quite peacefully and without struggling to breathe.

I have scrapped a lot of MRI magnets, and for a civilian, I have a good grasp of what is going on here. Actually, in some cases MRIs do indeed use LN2 liquid as a first stage cryogenic process. Actually one probably now obsolete MRI was the Oxford dual-cryo magnet that had both forms of liquid working the system. Now, a little-understood principle is sacrificial refrigeration in cryogenic storage. Since the CTP of gases like O2 N2, Helium and others is just so fuckin' extreme that there is no way it can be contained in a reasonable reinforced container. The pressure would rise to tens of thousands of PSI as the liquid warmed up. It would blast the container open, and one that would hold up would be unable to be moved! SO, what they do is contain it in a Dewars container, with a relief valve that "pops" at a reasonable "extreme". As pressure over a confined liquid rises, the boiling point does too. This feature means that as the liquid warms up. the pressure rises, and when the valve "pops" the escaping vapor causes a vigorous boiling of the liquid inside the massively insulated container, and this boiling robs latent heat stored in the liquid and lowers the boiling point of the liquid. When the available heat is depleted, the valve closes. This goes on and on as the pressure rises and falls. A locomotive boiler is the exact duplicate of this feature, except water has a boiling point higher than our native heat on this planet, so we add fire to boil the water. There is the cold head on the MRI and I think this thing is the pump that runs the gas helium above the iquid through a pressure-colling circuit to prevent the otherwise loss of helium vapor to control the rest of the liquid in the MRI.. I am of the belief there is no escape of helium normally occurring in an MRI. I DO KNOW THOUGH that if you hit the "QUENCH" button and turn on the heating-wire grid deep inside the MRI innermost tank with the Neodymium wire and spool it will instantly boil the liquid inside it and rupture the burst disc in the cupola and waste all the helium in a SPECTACULAR display of a jet engine sight and sound at the end of the discharge line!!! They said it costs $50,000 to re-ramp a magnet! Also, I have transported magnets to my demolition yard that still had small amounts of helium even after weeks of storage since thay can't recover all of it. Once you pierce the outer shell with a torch or saw (if the burst disc was still intact) within seconds after the vacuum is gone, the disc will rupture and roar away as the last of the helium vaporizes and escapes!

Helium, nitrogen, and maybe to a lesser degree CO2 work supremely as a painless way to go, and I think if you don't realize your oxygen-rich air supply has just been replaced with a straight no-oxygen supply you won't even realize it before you die!!! A lot better than all the torture- methods, even the "needle"!!

My wife and I have had this conversation several times - we both hated History in school, loved it as adults. I blame it on the focus on testing in schools... nobody really cares when the Edict of Nantes was signed. In contrast, I recall a tale of Ireland when Cromwell's army was marching through. Defenders in a particular area knew the fortress they had would come under attack, where the cannons would be set up, where the wall would be breached.... That all came to pass, with the invaders pouring through the breach, the rest waiting for the fortress gates to be opened. The gates never opened, and soon invaders could no longer enter. Piles of bodies blocked the breach. The defenders had set up a pen with a catwalk that enclosed the predicted breach. The catwalk was heavily manned and loaded with rocks that were thrown onto the heads of the invaders. Now, _THAT_ is history worth remembering, although I don't recall exactly where it was. I remembered the parts worth remembering.

I seldom miss your programs, and this one of your best. As usual, it is packed with useful information, some of it new to me, and I ain't no slouch. And presented with your easy, conversational, and non-threatening, touch. Good reminder on helium as the second most common element, and it being discovered in the sun before we found it on earth. Thanks a million for your valuable work!

Great story as usual history guy. Your channel is one of my absolute favorites.

THG - I recently decided to stop freeloading on your wonderful videos and clicked the "Join" button, and I am now doing the same with all my favorite channels. I hope you never stop making such quality content, and I thank you not only for what you have already given us but also for whatever you put out in the future. I hope my small contribution helps keep you "on the air" for a very long time!

Not gonna lie, I'm a little disappointed History Guy didn't open the video with a high-pitched voice. XD

Hi Mr. History Guy. You have have the greatest stories. I am continually amazed to hear new historical vignettes, of which I had never before heard. Thank you

Hot Dang man.....You sure done your homework on this one....It is beyond me how you got....All of the out so very well....My Hat is surly off to you...W0W....Thanks so very much..!!!!!!!!!!

The history guy meets the chemistry guy😂😂😂 thanks H.G.....another interesting one!!

*Firstly, keep up the AMAZING work!!!* I do greatly appreciate the time, research and effort you put into keeping history relevant and actively available for all to experience! This is a super important endeavor!!! Second: This is easily my FAVORITE video from you!!! I love history, but even more, I love science and the like, so this video was a real treat for me!!!

Wow! One of the longer episodes, and this on a scientific topic. I learned a lot more than I expected because it challenged so many preconceptions I carried. Fantastic story, painstakingly researched, wonderfully told. Thank you, Mr History Guy!

This channel is a gem. Also you should do a video on Sam Byck's attempted assassination of Richard Nixon by hijacking a 747. I'm in the production of Assassins at our theater and his story is super unique and completely forgotten

this episode was a gas!

I really loved that this one was unabashedly longer. Very good video, i learned a lot!

An excellent, complete and entertaining video. Very well done !!!

Your videos are very well presented and enjoyable. I miss the days when you could find succinct information like this on tv without somebody declaring everything is because of aliens.

I really got a rise out of this interesting story THG. Thanks for lifting my spirits!

really well put together history lessons from this guy. He makes history interesting. Thanks for the vids

I love this stuff. One of my favorite channels. Thank you

Interesting but even better for me you had a short shot of the ZMC-2 blimp which was built between the World Wars of Aluminum.

Excellent summary - learned so much I'm light-headed.

Pete - It must be all the helium.

The bigger store here is how one scientist built upon another scientists findings, over and over again. They opened unforeseen areas. How powerful is the unfettered sharing of scientific knowledge!

Love your history videos! Keep it up!

Besides history. I find the sciences fascinating. Thanks for making a connection.

Helium is still used extensively for scientific experiments such as X-ray absorption spectroscopy, or in layman's terms the study of materials and samples under pure X-Ray light, and observing the spectrum given off in a pure helium atmosphere. To put things into perspective, the Synchrotron physics lab where I work, uses about $30,000 worth of helium per month!

Where I work we make fire protection equipment for aircraft. The sensors have to be sealed so we inject a bit of helium into them right before welding them shut. The sensors are then put in bell jars attached to spectrometers, the air pumped out and then checked for traces of helium. I had no idea that test went back to WWII.

@@JeffDeWitt Helium is an impressively tiny molecule, and we also use it for leak checking our vacuum system on the particle accelerator ring. Very cool that your method dates back to ww2!

Excellent and informative! Thank you.

Happy 4th of July.. History Guy..thank you for what you do.

I'd love to see an episode about the Acre of Massacre in the Second Boer War, especially because it involved both Winston Churchill and Mahatma Gandhi.

There are 150 thumbs down on this... what kind of viewer could not admire this?

This was a fantastic video. I hope it means we will be seeing more science history videos from you.

Wow. What a great job you did explaining the molecular side of this element. The rest was great too but that middle section was so dense with facts and delivered in such a faultless manner it seemed to me it must have taken ages to get all those ducks lined up, delivered and recorded in a seamless stream that must have lasted for 5 minutes. Bravo.

Well, MRI scanners and hadron colliders are great, but helium's most important use can only be noticed by inhaling it and then saying something weighty.

Interesting topic to me. I work in industrial cryogenic liquid / gas production. I use Helium on a daily basis as a carrier gas for on of my laboratory instruments.

Quite an amazing presentation. Well worth listening to and a very informative piece of history. You are looking nicely dignified with your bow tie and all, Thank you!

You are a great storyteller. I'm going to watch your entire catalog.👍

Love it when you include pirates!!

I grew up in Kansas. I had no idea of the contributions of the state to the helium industry. I’m sure that there’s a bunch of the stuff in Oklahoma due to all of the wells in that state.

You probably saw them and never gave them a second glance as you traveled down Oklahoma highways. Helium is transported primarily in "high pressure tube trailers" from the processing/refining plants to end users.

It was and still is used for some applications....for example....it's used in tri-mixed gases for mig welding stainless steel and in argon helium mix for certain aluminum alloys

Always welldone. Thank you

This one was very well done Sir. Thank you for sharing your knowledge with me. As i work late I usually have YT on at work and like to listen to you.

If helium is a noble gas, then it follows that methane, as a contributing factor to flatulence, must be an ignoble one.
