    I work the cryogenics plant in Panama for the Air Force. We used a Compressor to pull in air, compress through 5 chambers, refrigerate the gas, pass the gas through silica gel to remove moisture, then blow to vapor into a tray tower. This would super cool the gas into a liquid. The nitrogen and oxygen would separate and we could store each into storage containers. This works off the principle of Increased Pressure = Increased Heat / Decrease Pressure = Decreased Heat. Keep up the good work.

    I saw a while back a video showing of the first people (scientists) that were competing to be the first to get to 0º-kelvin.
    And it was mainly done, of course, by liquifying gases.
    And if i remember correctly, it was Dewar who had an apparatus of various stages of liquifying different types of gases, in sequence where each one had a lower liquid point than the previous. A chain of liquifying gases. Up to Hydrogen, and then Helium (which he didn't get to).
    But i'm saying, maybe you could try this, because the gases were not wasted. And you could maybe hook it up to a solar panel with a compressor, make it self running. IDK.

Nothing to cut, nothing to weld etc. But this was just an example... I'd like to build a lot of other things. But watching Cody kind of relieves this will to build things and do experiments I've had my entire life !

    Cody, I used to do this alot (work at power plants where we have tanks of liquid N2 to blanket our steam drums to prevent corrosion when not running) just for fun. Typically immersing a test tube in LN2 and putting pure O2 gas inside the tube to allow it to condense (from an oxyacetelene rig). The LOX will be a pale blue color when it is pure, not clear. You have probably figured this out by now, but I just wanted to mention it. Love your videos. Keep them coming!

When we went to buy the oxygen (we both were 15 at that time) we asked the dude from the hardware store if we were even allowed to own 350 liters of oxygen (compressed into two .9L bottles) and he just said "Eh.. A little bit of oxygen never harmed nobody.." i suppose rules for that just aren't that strict in europe..

  • @watcherwatchmen7785
    @watcherwatchmen7785 4 года назад +1

    Cody you could have brazed the stainless steel to copper no problem. You just need to use a brazing rod for that application. You can braze ALL dissimilar metals together as long as the alloy turns liquidus before the base metals being joined. Also having clean surfaces prepared before you start. Another cool thing is that if the gaps between the parts is a very tight fit you only need a tiny bit of brazing to fill it. The tighter the tolerance and the thinner the brazing, the stronger your joint will be. More isn't better.

      Light1500 it's not methane, it's CO2. The tank still has oxygen in it so the bacteria are doing aerobic respiration. For methane to be produced there must be no oxygen in the tank so the bacteria respire anaerobically.

    I did this same experiment when I was in high school and I didn't need to build any fancy equipment. I very simply filled a large styrofoam cup with liquid nitrogen and placed a bunch of empty test tubes in it, mouth up. Oxygen with some argon started condensing inside them. Of course there was some water ice/dry ice in it though. I then combined all the test tubes together and it filled one all the way. It was pale blue and magnetic. Igniting paper in it actually exploded and I have a small scar from it.

    If you think about it, it only makes sense that it would pull air in and constantly liquefy like that. The air already in the tube liquefies, presumably leaving a tiny vacuum, the condensation is pulled out the bottom by gravity, making it pull in from the other end so long as the tube is cold enough to condense the gases coming in.

    Love these videos. A follow up, it it hasnt been done yet, would be to separate H and O2 from water through electrolysis and chill the gas as it escapes. I cant help but think, submersing your welding O2 in liquid nitrogen would be easier than chilling the gas as it passes through the tubing. but then it leaves you with a cold sealed tank of O2 that you need to poke a hole in.. Maybe thats not such a good idea after all.

    I solder to stainless fittings to kegs for brewing all the time. Use Harris Stay Brite #8 solder, Harris Stay Clean Liquid Flux, and keep it VERY clean with some surface abrasion to get through the passivated layer. Cleanliness is very important (much more than Cu soldering) and the Harris products are high silver content compared to regular solder. But if your parts are clean and you use the harris stuff, it solders even easier than copper because to lower thermal conductivity keeps the heat where you want it and you can walk it around. It's easier to overheat stainess soldering than copper though for that reason too.

    Liquid in the copper pipe is the condensate of air as you know. But liquid use around 1000 time less space then gas. So, you have a pressure difference in the tube and It's constant because the liquid is evacuated and avoid and equilibrium of pressure with stand still liquid oxygen.

    You could use pressure swing adsorption with molecular sieves to concentrate oxygen. There are medical devices that do this instead of bottled or cryogenic oxygen for pulmonary disease management. Concentrators are also used in some fighter aircraft to reduce hazards of compressed or cryogenic oxygen.
    I am pondering an argon concentrator using the same process so I will never run out of shielding gas for my GTAW welding..which works very well on stainless steel ;) not that I am volunteering to be your welding guy but it could happen

    Hey Cody, I did a bunch more testing with the liquid Oxygen today, and I discovered a reaction I think is definitely worthy of video, as I couldn't find it anywhere. Kerosene and Liquid Oxygen. It explodes very quickly. I dumped an unmeasured amount of Lox into a tin can containing kerosene, and lit a fuse. Maybe 200 milliliters of the stuff created a fireball/flash about 25 feet tall. Definitely try it out.

      Liquid oxygen is used to treat a variety of respiratory conditions. It is safe to breathe. However compressed gas is a much more common method of supplementary oxygen delivery. I work for a respiratory/home oxygen company.

  • @mathbc1984
    @mathbc1984 7 лет назад

    A way to purify the oxygen from the air is to use the same principle of a water smoke pipe but fill with nitrogen. The water will froze at the entry and form ice that will stay in the bottom of the jar. The the magnet you have and gravity (Oxygen is heavier) to separate the small amount of oxygen from the nitrogen. The Nitrogen melt at -210 °C and Oxygen at -218 °C. By the way, I love your videos of DIY materials production.

    why is liquid oxygen magnetic?

    • @lloydevans2900
      @lloydevans2900 5 лет назад +1

      The dioxygen molecule (O2) has a couple of unpaired electrons (one for each oxygen atom) which gives the molecule a dipole and makes it susceptible to magnetic fields. This isn't just true of liquid oxygen - gaseous oxygen has the same properties, but in the gas phase the material is not dense enough and the molecules have too much energy - they are moving around too fast for magnets to hold onto them. Liquefying the oxygen not only removes a lot of the energy but also increases the density by a factor of almost 800, so the magnetic effect becomes much more apparent.
      Technically, oxygen is paramagnetic. This means that it has no magnetism of its own - it cannot attract steel objects, for example. But in the presence of a magnetic field, the dipoles in the oxygen molecules align and become magnetic, which is known as magnetic susceptibility. The result of which is what we see when liquid oxygen is brought near a strong magnet - it sticks to the magnet. The effect is similar to ferromagnetism (seen in iron, steel, nickel, cobalt and rare-earth magnets), but a lot weaker: It takes a powerful rare-earth magnet to have much of an effect on liquid oxygen - a conventional and much weaker fridge magnet barely interacts at all.

      RuNe Voltage i mean, if it wasnt for the fact it would freeze your insides if you breathed or drank it, it probably wouldnt do too much harm, though there may be some issues with something so magnetic being in your body, simmilar to how people die if they consume small magnets from having crushed organs. it is noteworthy to say that drinking liquid oxygen wouldnt be the same as breathing

      Believe it or not, oxygen is very toxic in above normal doses even when breathed in at atmospheric pressures. If the oxygen isn't used up or expelled from the cells fast enough radical species can build up quickly and initiate peroxide chain reactions causing all sorts of havoc.

      @frizzykid100 7 лет назад +8

      It would immediately start boiling in your stomach releasing a lot of gas because liquid oxygen contains 4000x more oxygen then what you are breathing in from the air, which would build up pressure. This pressure would likely travel up your esophagus into your lungs causing them to collapse as well as tearing holes in your stomach.
      yes it will very likely kill you

  • @bengriffin4027
    @bengriffin4027 7 лет назад

    The reason the paper was difficult to ignite was likely due to two factors, but not liquid N2 concentration.
    The first thing is that the cold paper was condensing atmospheric water which tends to smother a fire.
    The second thing is the cooling effect of the evaporating gasses. Fire must reach and sustain a minimum temperature to continue. That temp is fairly high for paper to burn,

    Good video, I was unaware that you couldn't purchase liquid oxygen. When I was in the navy we serviced our aircraft with LOX (liquid oxygen) it was added to small round green bottles (about the size of a basketball) the service carts had large cylinders that were pressurized to 5000 psi all the wrenches and other tools were made of brass to prevent sparking. Occasionally some of the LOX would spill on to the ramp when the lines were removed while filling. and a buddy of mine decided to stomp on one of the larger drops of LOX and it blew the heal of his LOX boots off funny as hell to see his leg jump up when it happened.mid enjoy your video's keep up the good work. Don't let the easy u tube money distract you from your potential contributions to the betterment of mankind. Have you done anything with graphine? I believe there is allot of potential in Graphine.

    You need to run a drying filter to remove the water from your system. You can get one cheap from harbor frieght or any auto paint supply place. you can hook it in line before it gets to the cooling chamber. As soon as you started blowing through it I was saying,yup he is putting a ton of water vapor into it. In the winter when it is really cold,that is why people complain about having dry skin,dry throats etc. The colder temps convert water vapor to ice,essentually drying the atmosphere.

    Hey Cody, I have an experiment to think about if you are interested. It involves Foam Metal tubes wrapped in carbon fiber, and filled with Hydrogen at pressure. It is meant as proof of concept that you can build a strong low mass framework for a vehicle that acts as the fuel cell to power itself. I think something as small as a few oz would be enough. And it doesn't have to perfectly seal.
    I believe a rigid frame saturated with Hydrogen could be scaled to any size that would power mechanical force more efficiently than any foreseeable battery technology.
    Also the Methane would kill your animals long before there was any danger of explosion. A bit morbid, but at least you never have to worry about an explosion.

    stainless steel isn't a problem to weld. It's just more fluid like when melted than normal steel. you should be able to get special wire for stainless (most food grade stainless is 304). i would recommend tig welding it if you can though as it provides more control than mig.
