I used a nitrogen membrane and Stirling cryocooler to liquefy nitrogen out of the air. For this video I partnered with Starbucks to celebrate their Nitro Cold Brew. Order one here: starbucks.app.link/derekmuller
Making liquid nitrogen is hard - in fact up until 150 years ago scientists doubted whether it was even possible to liquefy nitrogen. In 1823, At the royal institution in London, Michael Faraday first produced liquid chlorine, kind of accidentally by putting it under high pressure. He similarly liquefied ammonia.
Borrowing a mixture from Thilorier in France, a combination of dry ice, snow and ether, he reached a temperature of -110C. By 1845 he used this mixture plus a hand pump to pressurize gases to liquefy all the known gases except six, which included oxygen and nitrogen. These became known as the “permanent” gases.
A French Physicist Aimé compressed oxygen and nitrogen in tanks and then lowered them into the ocean over 1.6km deep, where the pressure got up to 200 atmospheres. Still the gases didn’t liquefy.
Only at the end of 1877 were the first droplets of liquid oxygen and liquid nitrogen produced, by Cailletet in France. He first tried oxygen by compressing it up to 300 atmospheres, cooled to -30C, but that wasn't even enough to liquefy oxygen. But when he suddenly released the pressure, the expanding gas cooled, he estimated to -200C and he saw a mist and then droplets slide down the walls of his vessel.
It's amazing how far we've come in that now I can purchase a helium-based cryocooler. It compresses and expands the gas to absorb heat from the tip of the cold finger and eject it into the surroundings at ambient temperature.

I don't think it's bubbles moving down that you are seeing. It's liquid falling past the bubbles that gives this illusion.

I'm dumbfounded😮. So you know just about everything about everything? I'm over here afraid to plug in my air compressor out of fear the tank will bust! I mean, how did someone know how to filter out oxygen for goodness sake? And a piston pump with helium!??🙁 Whaa!!? How did ppl learn how to get different gasses like that form the earth in the first place? I'm glad ppl like you are in this world to help push us forward. I'll be a test dummy..the world needs those I guess..lol

Where did you get this Stirling cryocooler from? By the way, the first systematic production of liquified gasses was by Carl Siemens around 1857. He patented it.

After the compressed air passes through the nitrogen membrane, does the concentrated Nitrogen come out of the unit pressurized or did they have too use the air compressor to pressurize the Nitrogen? To my observation it looked like the pressure line that was connected to the membrane produced the pressurized Nitrogen through the line into air tank. So my question is is the concentrated nitrogen coming out of the membrane already pressurized?

To make liquid nitrogen from "scratch" u will need a cryocooler. Total price so far: $2000 I'm gonna stop right there

Ever heard of the irish beer Guinness? well it's very famous in the non america world (not surprising that muricans are ignorant of the rest of the world afterall), and it is also made creamier with nitrogen and has a coffee flavour to it. What starbucks did was kind of copy it and present this to the murican market! pity you didn't mention it in the video!

Who wants cold coffee? Who wants cold coffee with bubbles? I dont even like coffee, but that starbucks stuff is really beyond me. Seems to be to be the same disusting thing as bubble tea or the like. Its all pointless, you can not improve on something as coffee or tea by creating "products".

Nitrogen is great for car tires! The nitrogen molecule is bigger than oxygen molecules, so the pressure doesn't leech out through the rubber as fast

Great video, I didn't know the oxygen was attracted to magnets...I wonder if liquid air could be poured through a large tube filled with electro-magnets to remove the oxygen? Then when you turn off the EM field the liquid oxygen would fall out as well, thereby acquiring both liquid nitrogen and liquid oxygen.

What were the energy demands on these methods? Would you say any of them is less than the energy you get from burning a fuel with the equivalent amount of oxygen you removed?

Why cant this be turned into a motor to make a superconductor and make something float in the air. Im sure this is a key to antigravity. Larger scale needed. UFO motor. Regenerative capabillitys.

Dude, use an audio filter to trim down the oxygen alarm beeps. My neighbors thought it was a smoke detector and called 911. “Fire? No a guy on TRvid was purifying nitrogen on a dare from starbucks and....I...need to get out more.” It’s just a pet peeve that comes up again and again when people record some kind of alarm or alert sound and let it go on and on and on. Same for police and fire engine alarms. Given that you can use videos to make people’s Alexa order things from amazon just remember you’re steaming realism into people’s home and office environments and alarming sounds are...well...alarming.
