LOX is easiest to make with LN2 since it boils a few degrees hotter at ambient pressure. All you have to do is leave some LN2 exposed to the atmosphere and it will form LOX in situ. A full red 16oz solo cup of LN2 (insulated inside a styrofoam cup) will yield approximately 4oz of LOX over the course of ~20min in 70 degF standard lab air. My lab was using LN2 to cryofracture SEM samples and (as the LCHO, or "safety guy") I had to purge the overnight pressure build-up on the vapor side of the high pressure storage tank and then purge about 2 liters of ambient pressure liquid to blow out any ice that formed from water diffusing in during the vapor side purge. Suffice to say, I had plenty of spare LN2 to play with for a while. Some vids of it dancing about in the lab hood should still be on my channel somewhere. Making LOX was a fun little side project, as was ozonating it and seeing just how high a concentration could be allowed before it got angry (all ozone is always angry at all times). Pure LOX can be made by distilling off the N2 from the liquid mix in situ. Simply combine many aliquots of collected LN2/LOX mix and allow the N2 to escape. This cascade will bring you arbitrarily close to pure LOX. Most trace gasses will freeze out and a coffee filter can be used to remove them. Just keep all sources of ignition away. Pure oxygen makes just about everything containing carbon explosively flammable. Also, oxygen can be quite toxic. Don't breath the pure stuff if you don't have to.
My guess is that perhaps it's related to piracy? Considering his name "hyperspace pirate". Perhaps he got arrested and convicted of online piracy of videos or games or something
Some Bits from a fellow Alternative Fuels Nerd: - I would 100% be down for a series where you try and run a Natural Gas / CNG Generator on a LNG System you make! (“Adsorbed Natural Gas” is a thing to check out too) - I mentioned this in my safety bit, but for not just that but also procedure/system design checking up on the Code Books and Academic Literature (that is if you haven’t already) for LPG, LNG, Cryogens/Odd HVAC Stuff etc may be worth a look. Sidenote “LNG Train” is a common term for a unit at a plant that makes the stuff (they can have multiple for more throughput) - FINALLY Check out “Dimethyl Ether”, it stores like Propane, Works well as Diesel (Cetane Value is higher than diesel, and as with Autogas (ie lpg in Spark ignition engines) it evaporating quicker can help with fuel injector effectiveness (also can condense air/generate boost *i think* ). It is made Catalytically, often from Methanol, so given your experience, i THINK you could totally make this. And again a series running it in a cheap amazon/ebay single cylinder diesel engine would be REALLY cool. Just a thought from a MAJOR DME nerd lol. Hope this helps/was interesting and keep up your great work!
Another great vid. I feel I have to say two things that you probably already know, but I'll feel better having said them: 1: Eliminating ignition sources is not enough safety. You need to be ensuring that you're not forming an explosive mixture in the first place, because sooner or later an atmosphere that can ignite, _will_ ignite, either through an unexpected ignition source (bear in mind we could be talking unexpectedly catalytic materials, not just something above the autoignition temp) or just through the Maxwell-Boltzman energy lottery. 2: It's pronounced "car-no", it's French.
I saw a video where a guy drove over an oil spill on the road and one guy commented that "driving over an oil spill is not only a traction problem but a fire hazard". Most of the replies were people telling the commenter he was dumb and that it is near impossible to make the oil catch on fire by driving over it. I am now currently worried by the self centered confidence of people thinking nothing will go wrong because they know better.
@asandax6 Like telling an aircraft mechanic they shouldn't step on liquid oxygen bubbling on the ground due to grease on their footwear could ignite 💥
0:48 In some countries compressed natural gas is a semi common form of vehicle propulsion, with cars using it being very energy efficient (good mileage per kg of methane) but not able to hold much. Liquefied natural gas is also used but only on heavy trucks and buses
12:01 I don't know if I just have good headphones. But the background noise in this video was messing with me. Sounded like someone was banging around in my house.
I just have to say thank you and congratulations! I normally watch videos on 1.5-2x speed. This video is the first ever that I am actually slowing down to watch. 💪🏽👏🏼
@13:25 Try suspension for thermal insulation! like some fishing wire and a small rig (or even thin metal wire fastened to ceramic coated something). It can be more trouble than it's worth, but sometimes it works like a charm.

When I used to make solid nitrogen from putting liquid nitrogen in a vacuum chamber I'd put the dish on a foam kitchen dishwashing pad. The kind of really soft yellow polyurethane type foam. It works better than syrofoam because sometimes when styrofoam expands the dish can fall over.
Hyperspace Pilot, Cold is the unexplored realm. Fascinating and love the numbers. Edwards Deming "without data youre just another person with an opinion", and HP numbers = data is good enough for me. Closing the loop on a calculation by coming at it from multiple directions , beautiful work. a few glass beads in the vacuum chamber before freezing the methane might lift off the base, just a guess. Inspiring channel.
They're pricy, but go to a nearby HVAC supply house. Some of them will sell to the general public, get 5 percent brazing rod. The silver content is lower than others, and it requires more heat and prep. But, it'll stand up to pressures high enough to ruin a compressor's internal bypass. That's somewhere between 400 and 500PSI. I've never had issues with 15 percent silver solder, but its actually more expensive than 5 percent, melts at a lower temps, but it's softer so it may not stand up to higher pressure.
Woohoo, another Hyperspace Pirate video! Thank you for the great content brother, love this series. Question... doesn't the glass wool make your hands itch like crazy? I get flashbacks to crawling through my attic space to insulate it with fiber glass batts /shudders
You need to let your refrigant pass through about half your exchanger, which will liquefy against the heavier hydrocarbons. Run it into a seperstor, then let the liquified refrigerant cool the bottom of the cooler. The stuff that doesn't liquefy is the lighter side. Let that run through the whole thing, which will make it liquefy and just use that against the coldest side. You'll end up much colder. Yes, people who are annoying me for NDA violation, Ive checked. There are google search PFDs with this design visible. Also, cold spots at the bottom means you have too many heaviest, including butane.
14:04 it’s funny, as soon as you showed that burrito reservoir I yelled at the screen “there’s no way those ends will hold!” Not exactly an Einstein observation, I know, it’s just funny later in the same video it did the thing. :) You’re amazing - keep up the great work!
Refrigeration has always been one of those things I knew very little about. I still do, but now I have a sense of how much I don't know. Maybe one of these days I can actually diagnose my AC issues without paying someone to do it for me.
If you don't like dealing with glass wool you can use vermiculite instead, it's a good enough insulator for the job and is dirt cheap at hardware stores. You could build the box out of foam and foil tape, drop in your coil, then fill in the bulk with the vermiculite.
Here in Sweden CNG(Compressed Natural Gas) is almost as common of a fuel for cars as gasoline and diesel, especially within the municipality, they even see it as a green alternative alongside with electric cars to gasoline and diesel. In my city it is beeing produced from the food waste fraction, at my local "landfill" recycling station.
In the rocket world we often hear about liquid methane being a particularly "frothy" cryogen. It really is! Awesome to see it visually during the beaker pours.
I don't know if you own or are renting your house but if you are renting it may not be code so you will want to revert the system back before inspection as I am sure such a use may fail inspection. Even if you own the house it may fail the inspection of the system to ensure it is still functional. Removing moisture is also good because moisture can destroy the compressor and even the oil. I think it causes the oil to become acidic and breaks down the varnish on the windings and causes a short.
One correction! Liquid hydrogen does not escape through metals as freely as you stated. While it is is true that hydrogen does diffuse through materials in the gas phase at a larger rate than most molecules, the same cannot be said for the liquid phase. In a liquid form hydrogen actually swells on the atomic scale, while at the same time the solid lattice shrinks. Therefore in a liquid form, you won't see nearly the same rate of diffusion through solids (I studied and ran liquid hydrogen diffusion research experiments in grad school). We're talking 20 years to fill a ping pong ball type of slow. Overall have been loving your videos! Keep it up!
Also remember that glass wool is moisture permeable, so at low temp. it condense inside insulation making less effective insulating material. Use Polyurethane Foam for or styrofoam .
There is no need for a moisture filter between the compressor and the natural gas. Natural gas is usually dried to a very low moisture content to avoid condensations in the gas pipeline.
I was thinking of creative ways to go off grid and maintain pure self sufficiency without having to do everything by candlelight and silly stuff like that. So I looked at biogas as a regenerative fuel source. It contains methane, CO2, hydrogen sulfide, water vapor and other trace gases. So I found simple ways to remove everything but methane. I then considered condensing it into a liquid propane is. I then found that is insane as illustrated by this video. It had me realizing why rural areas are supplied with propane and urban areas with NG. NG is plentiful. If every home in America had a pipe running NG to it like powerlines. That’s a ton of gas filling the NG pipes. So much unused gas. So it’s more practical to have the two most common fuels used the way they are. Meeting the need at the cheapest prices possible. Btw biogas is so labor intensive. The inputs rarely equal the outputs. Y
Try putting an auger on a small cylindrical evaporator and making a slurry / slush puppy thermal battery for AC storage. If you get a time of use tariff it can load shift into the cheaper hours of the day.
12:35 Clever idea to use the evaporation to cool it off as you drop the pressure to approach the triple point. :) I think the slope of the PVT chart not in your favor here?
I just tore down a rather large compressed air cooler/dryer, So if you need a bigger compressor ive got one with a lra och 48A 11A normal. This is altho 400v trephase. Shiping to the states will be a killer tho.... Cheers.
Is it possible to effectively accumulate a cold buffer of 100-200 liters? How quickly will it heat up given its maximum insulation? and can such a buffer somehow help such a system?
I wonder if it would be possible to take advantage of phase separation to be able change refrigerant mix while the cryocooler is operating. Build it like a separatory funnel So you get down to the methane liquifaction temperature and dump the liquid into a storage tank, then start introducing argon to make up the difference in pressure drop.
Try to remember that when you're insulating you want to not "pack" it, you've said it a few times in videos and IDK if you mean it literally or not but its really the airgaps in the insulation that insulate it not the product itself so packing it tight only lowers its insulation vaue.
1:42 you forgot the biggest hazard of hydrogen: en.wikipedia.org/wiki/Spin_isomers_of_hydrogen "If orthohydrogen is not removed from rapidly liquified hydrogen, without a catalyst, the heat released during its decay can boil off as much as 50% of the original liquid. " That means if you liquefy hydrogen quickly, it can escape through solid material... with gratuitous and destructive force.
Radiant heating becomes a larger issue as the differences in temperature (room vs cryo) become larger. I’d love to see your setup inside a large chest freezer!

The safety warning is legit. Look up house natural gas explosions. Think 'crater filled with finely-shredded house'.

Try to remember that when you're insulating you want to not "pack" it, you've said it a few times in videos and IDK if you mean it literally or not but its really the airgaps in the insulation that insulate it not the product itself so packing it tight only lowers its insulation vaue.
Of course the burrito exploded 🤣🤣🤣🤣
1:42 you forgot the biggest hazard of hydrogen:
en.wikipedia.org/wiki/Spin_isomers_of_hydrogen
"If orthohydrogen is not removed from rapidly liquified hydrogen, without a catalyst, the heat released during its decay can boil off as much as 50% of the original liquid. " That means if you liquefy hydrogen quickly, it can escape through solid material... with gratuitous and destructive force.
Can't wait for the solid methane vid
One interesting thing you could do with this setup potentially is make methane clathrate, or flammable ice.
Radiant heating becomes a larger issue as the differences in temperature (room vs cryo) become larger. I’d love to see your setup inside a large chest freezer!
Very impressive!
Welp, you may wanna test burritos with a water pressure washer, they tend to go 100+ bars or use relief valves. Awesome setup.
8:45 that's a classy bathroom right there
