at 14:10 you should really be wearing some gloves for thermal safety from frostbite, aka frozen skin & body tissue. Which is very is nasty & painful to experience. You can quickly cause your hands to become damaged, in very a painful way as they thaw and the flesh may be necrotic. Requiring amputation. Freezing your flesh or "Frostbite"(the name trivializes how serious it can be )is something people climbing mountains like Everest fear more than falling. Cool experiment and great teaching video , just please think about preserving your body. I used to work with dry ice in large amounts on shows, often breaking big blocks from the storage coolers into small pieces so they hard more surface area for the dry ice fog machines. There few more safety rules you want to follow, but that bare skin contact is big no no for the risk. Even if just momentary.

Furthest away one was found 100 meters away, mind those bottles are really heavy even when empty. This one has less mass and pressure, but its still enough to be dangerous if you fuck something up, so learn what is needed to make it safely, well as consider all the risks constantly. Its better if you can do everything remotely from behind the brick wall or similar shield to hinder it and mind having well ventilated area that allows co2 be replaced with fresh air fast.

I used a very simple dry ice puck maker designed for special effects use. It was two disks of wood with velcro hook strips glued and stapled on them, and a pipe connector tapped into one the disks. In use, a larger velcro strap was applied around the two disks with a gap for the puck of dry ice to form inside. Then liquid CO2 was blown in until the puck started making slight creaking noises. When the velcro was undone there was a nice solid puck of dry ice inside. That was an impressive way of making enough CO2. I wonder if the first compressor was angry about being started under pressure, since they aren't really designed for that.

There is also a chance it melted some insulation because he ran a heavy load with no cooling (usually refrigerant provides cooling in addition to the oil.)

I think there is still a lot of potential to increase the yield by precooling the CO2 liquid to reduce the vapor pressure. Try using a bath of ice in saturated saltwater to get it below 0°C. Also you could take inspiration from the Linde process: Fix a copper tube to the CO2 pressure vessel and squeeze the end nearly closed, so that the flow of CO2 is throttled there instead of the valve. Put this upside down inside a thermos bottle or dewar - preferably a narrow one. The CO2 cools at the throttle at the bottom of the thermos. The escaping gas will then precool the liquid in the copper tube and increase the yield. Of course you must make sure the copper tube can take the pressure. It might be brittle at low temperature.

Your Embraco is a R134 refrigerant. In order to reach high pressure you should use a R404 or R410 refrigerant type of compressor. Danfoss series SC12CC or SC15CC. Also preferably look for a "medium back pressure" as they are suited for higher current through the stator. Putting current through the stator without the rotor running results in no counter EMF (Electro Magnetic Force). Every stator will burn if you do what you did. Notice that all hermetic compressors are protected with a bi-metal current limiter. So the click you heard probably is the over current protection, which will reset itself automatically. When you start experimenting with ethylene, make sure the first trap is at least -30'C, otherwise pressure will be too high. Use preferably R410 in your first stage. For the second stage you will be unable to find an expension valve. You can only run this stage using capillary. It is a long way to get a two stage system working from scracttch or know-how. You can reach me via linked-in, Roland van Hall - Tamson Instruments.

Something I was wondering in your last cyrocooler video, it did seem to be getting stuck at around dry ice temperatures. Given you were continuously taking in fresh air (and having to dehydrate it), perhaps you were getting CO2 freezing up inside of your system? At any rate, if you 'recycle' the exhaust, you wouldn't have to do as much drying. But, same goes for closed loop hydrogen, etc. If you do go the cascade refrigeration way, take a look at making some "R469" - its just a mix of CO2 and R410a (easily recovered from dehumidifiers, etc). Much easier to get than ethane or ethylene, but won't freeze at -55C (triple point at 5Bar) like pure CO2 would. I'd probably add some propane to the mix too for oil solubility goodness. (or better, "MAPP Gas", which is just propylene, boils 10c colder). Also, add a heat exchanger, warming up the suction line to the compressor, using the 'heat' left in the refrigerant after the condenser. Bit of warmth makes for more oily oil, and makes sure all the bits of the blend have boiled off. If you haven't played much with diy compression systems before, /other than running stupid high pressures which will cook the motor/ (or, near zero flow, depriving it of cooling) they're a lot more forgiving/harder to fuck up than various tradespeople on forums/youtube/anywhere will go on about - in terms of captube sizing, "fuck it, whats there might work" often does. BBQ tank propane+butane+stinkgas bastard mix will work in just about any system. There is roughly nothing in this world which needs to be brazed, (cheap-ish, "silver bearing", plumbing solder 100%. Cheap, by-the-litre-from-pharmacies "fatty cream" moisturizer+zinc oxide+Hcl= plumbing solder flux), and no brazing means no nitrogen purging (I use CO2 sometimes) - though I flush any flux, etc out of a system with ethanol first. Nothing needs to be vacuumed for more than 30 minutes, if it does, its leaking. (Oh, and try not to vent ODP/high-GWP refrigerants like the "professionals" do. Its so easy to recover them into old gas torch bottles for playing with later)

You will always burn compressor without starting device what is sitting on connector to steel egg that compressor sitting in. compressor have double winding... one for working and one for starting. This starting winding gettin power thru thermistor in starting device only for few seconds, because thermistor getting hot and resistance rise rapidly. Normally spark and boom comming from thermistor and many times You just have to change it to keep compressor starting again.... You can even use crued methood and use momentary switch to energize starting winding. Best regards.

Refrigerator compressors need to have the oil coming back in the return pipe. This lubricates the motor, cools the winding and provides the wet bath to seal the piston in the cylinder bore. Maybe drip some compressor oil into the intake? It will mean that the output from the compressor will be expelling an oil mist, which your set up will probably need to deal with.

Actually most of the oil does not dissolve in the refrigerant, with stationary home style compressors the oil usually stays in the compressor (unless it gets hot like in this circumstances). You really don't want the oil to get into the gasses being compressed, so, hmmm, using a little compressor like this one would need to fine a way to cool the oil. In automotive uses the lubricant, at least with R12(mineral), r134/R152a (PAG, etc.) the oil is soluble and flows with the refrigerant through the whole cycle.

This is AWESOME

I have a 20 lb CO2 cylinder for making soda water. It is not expensive to refill so that would be an option for CO2. Back in the 1980's I worked for Liquid Carbonic and we took CO2 from a fertilizer plant (waste CO2 from the manufacture of nitrogen based fertilizer) and processed it then filled railcars and trucks with the CO2. The plant had sold dry ice also (but by the time I started working for them they had stopped making and selling dry ice). The industrial equipment for dry ice was still there and we could still make some.

I think even if the motor was still okay powering the windings without the rotor like that can set it on fire, because if there is no ferrous something for them to magnetize their inductance is way lower.

I'm impressed 👍! Ty

Great channel! I am your newest subscriber. Great presentation! Awesome demonstration, excellent pacing, digestible graphics...and O THANK YOU for using your human voice!! On THAT note, consummate job with the audio! Your voice over is so easy to listen to and the music is perfect choice and so expertly tempered against the V.O. throughout!

love the video and the info is amazing and u keep it interesting the whole time!!

With no load and not all ferric parts in place resistance will be very low in the windings and will thereby very easily be heated up if used incorrectly. Very nice video! I've been working with dry ice production for a few years. Nice to see some hobby production!

This was fun. I was not expecting to stay for the whole video. Good video

Very entertaining!! Basic chemistry! Awesome and amazing

Beautiful , Interesting and very well explained, congratulations and thank you for shearing your knowledge

I love this stuff.

Fascinating!

Amazing dude

Love the KSP soundtrack in the background

I figured out how you figured this out .. the dog 🐕... The brains of the operation... Dude your amazing! Thanks for the video!

Put salt in the ice bath. It will get colder and you can condense the gas at a lower temp and pressure. There are other things you could add also. In addition you might want to make sure you purge air from the hoses. Good luck.

Super cool. 👍

I love the homebrew chemistry/engineering astetic

This is how a lot of my experiments go ! At first everything just fine going good and then all of a sudden my hi quality equipment pops and starts to smoke ; i can dig it

VERY cool!

Absolutly loved the video! All aspects of it. Subscribing and looking forward to more!
