- General purpose small homemade oxygen generator for using in the home workshop. Simple components you can find anywhere make it easy to put together this electrolytic device.
Caution: Do not breathe this oxygen, it is not pure. Usually water from the utilities contains salts which can contaminate the oxygen produced with chlorine!
I have been thinking of this set up since I was in Junior High School for our investigatory project..Now I know how simple it is...Thank you Chava Tarin.. you're a genius...
Of course, professional help is needed for developing a working project at a high generation level Thanks a lot!
sir..plz give me your contact number.
Ive just completed my first iteration of this generator on a much smaller scale for a small university project and it works great!! just need to play around with my amperage and NaOH concentration within the solution to provide the best conductivity. Thank you for making such an informative video!
Thank God, I am glad I could be of help to you!!! Thanks for your stimulating comment!!!

Wow what an absolutely excellent instructional description of an oxygen generator. Thank you sir. 👍
Thanks for your kind comment!!!
Very, very well done. Good script and good safety comments at the end. Thank you Chava Tarin.
Thank you,Brian, for your kind comment!!!
My school buddies dad had a machine in the back of his muffler shop that used this process to make oxygen. The machine looked very old in the 70’s so I would guess it would have been made in the 1920 to 1940 era. It took up about a 6 foot long bench. Just electric and city water hookup. He never had to buy oxygen for his shop. Plenty of pressure to run a cutting torch.
Thanks for sharing, Dan, indeed it's an old technology! It is a good practical way to generate oxygen, with the convenience of solar power, it becomes more and more inexpensive every sunny day!!!
Thank you very much, Chava Tarin!! You’ve shared an essential idea, complete with safety info; rn this could save lives.

Okay, I'm late to the party but you've explained this whole thing so well. I might try making this generator
Thanks a lot for your kind comment!!! Sadly, I think the party is not over yet.
I think it's awesome that two gases make a liquid! Separate the two gases and they burn but put them together to put out fires! Lol love it
As a matter of fact, Kevin, water puts out fire because water is already burnt. Water is the "Ash" resulting from burning hydrogen in oxygen!
@@eltunene lol
@@eltunene thats the coolest sentence ive read
I love this project Chava. It's simple and multi purpose. I'll be checking out your other projects too. Thanks,
Thanks, Frederick, for your kind comment!!! The generator was thought for using in a small welding torch, but with certain modifications, it can be used for other applications. First of all, the quality of the oxygen must be much better. Distilled water must be used, so no salts are present, which could pose a danger of producing other gases along with the oxygen, such as chlorine. A solar still can be used to save power in such a process. With regards to the amount of liters of oxygen per minute, that can be determined by the size of the generator itself, and MUST be checked by a health professional. Something else would be the energy consumed by a bigger generator, maybe solar panels can help here.

Thank you on your smart ingenuity of
producing oxygen .
This is a simple electrolytic separator. An important thing to note is that this process uses a LOT of electricity. It's a very costly process due to this. If you're considering separating out your own oxygen and/or hydrogen to save money, you likely won't. The cost of electricity will likely be more than purchasing the respective gasses from a manufacturer.
Yes, indeed, especially for large volumes, it becomes too expensive.
may be good if u have cheap solar power at home ..
Of course if you provide power from Solar panels you could bring the cost down.
It’s amazing that the water components are the elements of fire.
Welcome to earth 🌎! How easily we understand everything here is directly connected.
The components of salt are Sodium and Chloride (either of which on their own can easily kill you) but you can't live without salt!
Thank you so much for your easy-to-understand explanation, appreciate your generosity.
Dear Bahman, thanks a lot for your kind and encouraging comment!!!
Dear Glanze Epic, thanks for your comment; originally, the project was intended for a small torch, such as the kind used in jewelry. However, it can inspire somebody to keep researching and experimenting in order to produce larger volumes of oxygen. However, several things must be taken into account: Electrolysis consumes a lot of electricity; oxygen and hydrogen must not mix, they are explosive together; large volumes production involves a lot of heat production also, so the materials used must withstand high temperatures: any intention of medical use must be supervised closely by qualified medical personnel, even "known good" oxygen from tanks can be dangerous if excessive; water used in the process must be distilled water, since raw water from the tap may have chlorine salts dissolved as well, yielding to the production of chlorine along with oxygen; finally, if pumps are to be used to try to store the oxygen, they must be special, oil-less pumps, since oxygen is a strong oxydizer, and many objects, including metals, may burn violently in the presence of pure oxygen. Regards!

Thanks a lot, P N, for your kind comment!!
Nice explanation, but this oxygen generator has very low efficiency, since only about 0.5V of the 24V DC are used for hydrogen generation (actually even worse due to non-linear current flow after rectification). The rest is being converted into heat to warm up the water. You need way larger plates with a very narrow distance to each other and a much lower voltage per cell. That's why membranes for narrow spacing but good separation are the most difficul parts in commercial cells.
Yes, I agree. The idea was to have a generator anybody could build and use. Thanks for your kind comment!!
i join all comments praising the presentation, there is even a safety disclaimer i was waiting for, kudos for creating this, dear author
what about chlorine and other impurities? can anyone provide some input?
@@AlexanderBukh Dear Alexander, using distilled water is a must for obtaining high quality oxygen. Nevertheless, oxygen produced must be certified by professionals in order to be safe. An updated drawing is at ruclips.net/channel/UCmjQnuJwV0FkjdEyi3099RAcommunity?lb=UgwRGRtRxJVb63bdsUJ4AaABCQ . Improvements such as adding a solar still for distilling the water, solar power for saving electricity, are shown in this new drawing. I have known of people using the hydrogen to power a gas refrigerator. No amounts nor dimensions are given in this new drawing, since its purpose is to suggest improvements which suit the user needs. I suggest starting small and grow the system from there, using the principle given.
Mr.Chava Tarin, this prototype is badly needed by your people, it is for your immediate reply.
One thing i sugest is the negative connotation, the bolt that produces the hydrogen,, put the connection to the bottom end of the bolts, this maintains the conections in a submerged in water longer even when water level might lower, so prevents, inadvertant spark ignition...
Thanks to you again...sir...

Electrolysis is also very good for removing a rust from a steel, iron etc
but also very energy intensive, so this is a crap way to produce oxygen. oxygen concentrators do the same, with much less energy
Dear Christoper Eduardus, some gases are commonly found at standard temperatures and pressures as diatomic molecules, such as hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), and chlorine (Cl2). Other gases, which have their outer orbit completed, such as the rare or noble gases, exist as monoatomic molecules, these are are helium, neon, argon, krypton, xenon, and radon. Oxygen and Hydrogen, when separated from their compounds, naturally assume their diatomic molecule structure.
Great for producing very small amounts of gas, but if you want more volume I suggest using a whisk with copper scrubbers stuffed inside as your electrodes. They will provide far more surface area for electrolysis. Also, oxygen isn't just a good oxidizer, it is the ONLY oxidizer.
Thanks, Harold, for your contribution!!
@@eltuneneI Think the best should be inox!! copper or most of others metals ends by giving rubbish in electrolite! Never pleasant to clean and refill!
Why not use stainless scrubber pads 8n the wisk?
@@superjeffstanton Good idea! The copper does exude some nasty particulates over time.
Fluorine gas or chlorine gas are also oxidizers , much stronger than oxygen and thus not existing in free gas condition in our environment.
Great boon! during this COVID time!.
In India this is shortage now , system going out of control.
May god! if at all there let it come out through every doctor! and health care workers!!🙏🏻
People in India are very creative, they can use this or similar equipment and get oxygen, as well as hydrogen for running gas refrigerators to keep medicines.
brother u cant use this for clinical purposes as the amount produced is very less like 0.18 liters per minute where a breath takes in 0.5 litres oxygen(one breath)
@@harekrishnaparhi7943 you're right but it depend of the size and surface of electrode and also the power of electricity. But the real problem is using NAOH producing toxic gas
Does it matter what grade of steel you use? In other videos I've heard that low grade stainless steel can produce chromium along with the O2 which is very poisonous. What would be the best grade of steel to use for the cleanest Oxygen?
Mostly i know the solution is using platinum and silver electrodes then potassium hydroxide.

Genius Chava Tarin! Thank you.
Thanks, Alex. As a matter of fact this method for obtaining both oxygen and hydrogen goes back to the nineteenth century.
The homemade oxygen generator is actually the most basic example of the process of Electrolysis of water. One simply places a container over top the electrode(s) and collect that gas (be it oxygen, hydrogen, or both. The problem is ... the amount of gas type ... that you need to collect.
Using 24vdc, you will collect 3.33 milliliters of oxygen (per minute) for each 1 amp of current (120 watts of power). That is not much gas (oxygen). Hydrogen amount will be double that. (about 10 ml total gas)
Then there is the heat to consider.
2 volts (electrode voltage) is about the lowest heat producer in the water. Anything over that will dramatically increase water temperature; which will increase amperage flow. Now you need a voltage regulation circuit to control the rise in amperage, or temperature will runaway from your control.
Of course, one can add more electrodes ... in parallel ... to increase gas production; but each electrode will draw its own amperage amount .... which will also add to heating the water; and increase the wattage draw.
So, this is possible ... but not practicle.

There are a hundred different tutorials on how to make one of these, just look up Electrolysis or HHO Generator. Only difference between this one and those is this is focused on collecting the oxygen while an HHO Generator is focused on collecting both while mainly producing larger amounts of hydrogen.
@@b-rad7708 regarding medical purpose, the hydrogen will have to be oxidised at generation to create water vapour, so it does not get explosive.
That way the product will consume atmospheric oxygen and give out pure oxygen.

2 make sure the stainless surfaces are very clean before use ... even the oils from your hands can reduce the effectiveness
Excellent contribution!!!
Dear Gorilla Disco, the project is for supplying small amounts of oxygen for a mini torch, the amount of hydrogen produced simply goes to the atmosphere, where it recombines with oxygen to form water, ignited by static electricity discharges. It can also be collected and used to feed a propane fridge, however, I omitted this in order to keep the project free from the dangers of hydrogen accumulation and explosion. However, with due precautions, both gases can be stored and used separately.
DANGER!
During the electrolysis of water, ozone is generated at the anode and hydrogen gas is produced at the cathode. While you recognize the flamable dangers of these gasses, you seem to be oblivious to the dangers of ozone. YOU CAN NOT BREATH THIS!! It will damage your lungs. A simple Google search can confirm.
Was thinking the same but wasn't able to find proper diagram ❤️❤️❤️ well done thank u

Hydrogen when compressed is dangerous. If it's not pure it explodes.
Yes hydrogen can be stored however the cost of cleaning, compressing and storage make burning wood more efficient than hydrogen.

Dear Ismoyo, thanks for your kind comment!!
Great video. I want to know what is the proportion of caustic soda to be mixed with water. Please share.
A 40% ratio should be fine, that is, 40 grams of caustic soda per liter of water. You can slowly add about 10 grams of caustic soda to half a liter of cold water, then pour the solution into a bigger container, and repeat the operation. CAUTION: CORROSIVE AND DANGEROUS SOLUTION! do not add water to the caustic soda, but caustic soda to one liter of water little by little, since the solution generates some heat and if using a small amount of water, the water can boil and burst. Wear safety goggles and rubber gloves to prevent spilling of caustic soda to your eyes and skin in general. Always use enough water so it can absorb the heat and dissipate it, and add the soda into the water and not the other way. It is better to dissolve a small amount of caustic soda first and give it a try for operation of the cell. You can make the solution in a tall glass of water stirring slowly and adding some grams at a time, handle the solution with care. Do not touch eyes or mouth. On the other hand, the oxygen generated may not be suitable for breathing, due to other salts present in the water. Please check with a physician as to purity of the gas, before attempting to use it for clinical purposes. This project is intended for a small torch, with low volumes of oxygen produced.
Pure h20 is can't pass electricity easily. So it have to do mixed lemon juice costing soda salt anything

My budget is not very fat, and due to health situation, I cannot just go shopping for parts, nevertheless, I already experimented with getting oxygen in the past, when I was a thousand years younger!!!
@@eltunene nevertheless 👍🏻 appreciate your efforts!!
@@eltunene However, if you do not have practical experience, you cannot pretend your fantasies work. First of all, you have the wrong electrodes (screws). Minerals will accumulate on them. After a while, the "screws" will not work (they will not produce gas). A small source of weak voltage and current is more suitable for galvanizing than for the production of oxygen and hydrogen. You cannot absorb hydrogen in the free space of the box, but in the bell, as you have with oxygen. Replenishing water with a "toilet" mechanism is very optimistic - you probably expect a large production of gas, but this is a complete mistake. If you industrially produced hydrogen by electrolysis with a power input of several kW, it would be understandable. In the domestic embodiment, the water is replenished through connected vessels, i.e. by another "toilet" mechanism. It is also necessary to make the water conductive, preferably table salt. My hydrogen and oxygen (Brown's gas) generator has the right design and power source. It can continuously supply a small burner with which it melts glass.
It's electrolysis of water. HHO generators are a BS gas mileage scam device.
@@loctite222ms Scam device? They aren't a scam device to be honest, but yes plugging one into your vehicle and expecting it to power it is a pipe dream. The process of separating hydrogen and oxygen from water is a real thing.
Simply superb explanation Sir.
Thanks, Sreeramachandra, for your kind comment!! I sincerely hope this will be useful for someone!!!
I think there is a big mistake here: *ONE* screw only? there in no surface area there, it will only produce a minuscule qty of O2, no? Thanks
edit: i went back,and you did say that the surface area may need to be increased; anyway,that is the principle,and needed cautions, good video.
You´re right, the larger the area the more contact with the solution and the higher the amount of O2 produced. The problem is if oxygen is too abundant, there is the risk of a fire. Anyway, the principle is valid for bigger plates, generator cells and amount of water. You can even work with much higher voltage than the one I suggested, and get several liters of oxygen per minute.
@@eltunene several liters? i didn't know that,i thought you'd get much less; i will try that,i need a oxy-propane torch; but i do not want accumulation of that H2 anywhere,not even on top of the water either,may have to use a second bottle for that,vented to the atmosphere thru a just enough thin hose.
@@josepeixoto3384 Good idea! If you use separate hoses, maybe it will even work by feeding oxygen and hydrogen to two nozzles separately, and replacing the propane by hydrogen. By using larger electrodes, and maybe a higher voltage, you can get more hydrogen and oxygen (separately, in two independent hoses. You can build it differently by using two cells for oxygen and hydrogen, using PVC pipes. One basic thing to keep in mind is to leave the PVC open in the bottom and the electrodes at the proper position in order to have the liquid down until the electrode is not making contact with electrolyte at all, so the reaction will stop when the PVC pipe is almost full with gas. This will insure the reaction will stop and the gas wo'nt "spill around" the electrodes, allowing both gases to mix, which will not be safe at all.
An excellent presentation. Thank you sir.

Thanks for your good video..
But can you tell us how many NaOH% must be mix with the water %.. thank you
Nice to know.
NaOh acts as electrolyte to conduct DC current through water. The percentage is usually decided by current limit of power supply, but not everyone will have multimeter at home. So eyeballing the bubble and wall socket temperatures works just fine. If you add too much you will burn the wall socket.
For practical purposes. Start with very little until you see bubble rising, and then keep adding until you see whole screw covered with bubbles. Keep and eye on wall plug temperatures every 5 minutes, warm is ok but hot is not. If you add too much NaOH you will burn the wall socket.
I'm sure your homeowners insurance agent and building code inspectors will love the fact that your attached a flammable gas creating unit right on the side of your house.
Ohh, good contribution! The amount of gas is not much, but indeed, you are absolutely right!
@@eltunene I'm just saying that if you have this on the side of your house and your insurance agent sees it, he will likely drop you from your insurance.
Very good explanation.👏👏 Can we also use a full wave rectifier? Do we need to pour more NaOH after sometime? How much dc volts are necessary if we want to use this for medical purpose for one person?
Dear Santosh, thanks for your kind comment!! The diode bridge IS a full wave rectifier. If no contaminants get in the tank, no more NAOH is necessary. The amount of DC volts is determined by the medical professionals, depending on each case. However, if your application involves a human life, a qualified physician must check the quality of the oxygen being produced, as well as the quantity. This project was suggested with the idea of using in a non-critical application, for medical purposes, qualified assistance is necessary!

Thanks, Carmen, for your kind comment!!!
Wonderfully explained, thanks.
Use sheets of stainless steel(cheapish) mesh or sheets of platinum(very costly) mesh. The key to increasing the production of oxygen is surface area. The larger the electrode surface area, the more oxygen/hydrogen is produced. Sheets of stainless steel mesh can be bought in rolls of 20 meters and anything from 20 to 120 cm wide, maybe more. The oxygen produced must be cleaned in order to use it as medical oxygen. Mist of the electrolyte will follow the oxygen, but if bubbling the produced oxygen through a separate bath or two of water, it should be ok for emergency use until medical grade oxygen can be acquired. I would use bottled water for this, and when refilling, always add water to the extra bubbler and let this water again flow into the electrolytic bath. That way the cleaning process always has some freshwater added to it, and the electrolytic bath will keep at a constant strength.
Good enough, but production can be doubled by making the anode from aluminum metal and using dissolved (in water) sodium bicarbonate instead of aquious NaOH.

Dear Mayur, this suggested project is by no means a new invention, obtaining oxygen from water is a very old system, as early as the nineteen century, used at first to measure electricity (hofmann voltameter), and later for torch welding. However, a formal project could include a solar water still (to get pure distilled water), and solar panels for the electricity source. Please follow this link to a drawing I made illustrating improvements and updates for a more practical system. ruclips.net/user/postUgwRGRtRxJVb63bdsUJ4AaABCQ .
tu peux aussi utiliser du bicarbonate de soude, qui est moins dangereux. Le volume de gaz dépend de la surface des electrodes. Comme la tension de pincement est de 2.5 V environ, un transfo de 6 ou 12 volts est suffisant.

Thanks, Ginong, for your kind comment!!
What if I use 110V AC directly to a 600V rated Bridge Rectifier instead of the 24V that you are demonstrating to generate O2, would that produce more O2 and HH2?
Dear G RP, you are right! The more the energy, the more of both gases you get. However, you must exert some caution and proceed by gradually increasing the power applied to the device, since some heat is also generated. Maybe you could start with a smaller amount of NaOH dissolved in the water and watch for overheating of the solution (by disconnecting the power before checking the solution temperarure). You could also add an external limiter, such as a light dimmer you can turn back and reduce the amount of energy flowing through the cell and thus control the reaction. Please be very careful to check the two gases do not mix. Please let me know about your results.
@@eltunene thanks for the quick reply! That's a great idea using a limiter on the supply voltage and gradually increasing it. I'll use my thermal gun to monitor the temperature. I will let you know the results. Cheers!
Oxygen amount generated is proportional to the current in amperes or coulombs. So higher voltage doesn't mean high amount of oxygen, but making heat. The best is using a variable dc supply has voltage and amperage indicators.
Good narration, we learned this in our science class in 6th grade.....ELECTROLYSIS.
You are right, John, I used to enjoy my chemistry and physics classes. Thanks a lot for your kind comment!!
There is a world of difference between a few bubbles of oxygen in a jar in a science class and generating a useful amount of oxygen continuously, ideally without any explosion. You may know how a piston engine works but that does make you able to build a car.
Can we use this to fill oxygen in cylinders? Helpful in medical field now especially at places like Brazil where people are in high need for oxygen cylinders to fight covid.
Dear Justin. This suggested project is by no means a new invention, obtaining oxygen from water is a very old system, as early as the nineteen century, used at first to measure electricity (hofmann voltameter), and later for torch welding. However, a formal project could include a solar water still (to get pure distilled water), and solar panels for the electricity source, as well as special pumps to store the oxygen (and the hydrogen) in cyliners for later use. Please watch this video by a fellow youtuber ruclips.net/video/DFf0vP3Dtb4/видео.html and this article in Wikipedia en.wikipedia.org/wiki/Oxyhydrogen . By combining the oxygen cell, a solar still and photovoltaic electricity, large volumes of oxygen (and hydrogen) can be achieved at a low cost.
One of the problems that you can have is the chromium in the stainless steel that it is released as a result of the corrosion of the screw. Maybe, it is necessary to put some filters to clean the air and make some measurements.
to clean the oxygen
The ocean, the poles, the earth.
Great!! Few questions:--
1. Is the o2 such produced of medical grade
2. If there r impurities in o2 than how to filter out on o2 delivery tube itself
3. Can we attach flow meter in the o2 delivery tube to measure the oxygen prodced/delivered.
4. Should we used normal tap water keeping in mind the purity of o2
5. Hydrogen gas is highly inflammable & explosive..will it be wise to release it directly in the atmosphere.
6 how to store o2
Thanks buddy...if anyone can help
if positive electrode change to a bigger one, get more oxygen than hydrogen??
Dear Anjaly, water is made of molecules containing one atom of oxygen and two atoms of hydrogen. When electricity separates them, you get one volume of oxygen and two volumes of hydrogen, all the time.
@@eltunene thank you
@@eltunene I don't think so, the quantity of H2 is twice O2 provided that the two electrode are the same, otherwise the O2 quantity are bigger if the positive electrode is bigger than negative.
Beautiful simple tech. Thanks alot
This is old days tech. This method for splitting water into Hydrogen and Oxygen has been around since the XIX century! However, as you say, it's simple enough to build many medium size units for saving people! They can add a solar still for using distilled water, as well as a few solar panels for running the homemade generator.
THANKYOU OLD MAN!!!
Thank, you, for your kind comment!!
What if you distill the water (boil-condense) or us an R/O filter to remove all dissolved solids? Then would the oxygen be safe to breathe?
Thanks for your comment! As a matter of fact, You could use a solar still. In my section My Community You Will find a drawing of a simple solar still connected to the generator. Please keep in mind that the oxygen produced must be certified by medical personnel, and also that the amount of gas produced may not be enough for such application. There is a full explanation included with the drawing.
Thank you, great video
Remember to keep in a flame free place. Higher oxygen levels also means risk of explosions
Yes, indeed, oxygen is also an excellent oxydizer, which can make most substances catch fire, even some metals, but common materials such as bedcloth, drapes, pieces of furniture, can burst into flame, at room temperature. You are absolutely right!!
Kindly specify how much oxygen will be generated .will it be sufficient to treat Kovid patients.
Dear Avinash, The amount of oxygen generated depends on the size of the cell, as well as the amount of current available. The main thing is to make sure the oxygen is pure, and that can only be evaluated by a qualified health professional. Please try with a small device first and check the quality of the oxygen produced, if this is correct, you can expand the system, always keeping in mind that hydrogen and oxygen must not mix in the machine, since they are an explosive mixture, and also the reaction involves a small amount of heat, so you must check for that also, if the machine becomes considerably large. First of all, oxygen quality and secondly, check for heat generated. I have a drawing with suggestions, no amounts or sizing specified, but the main features such as layout and electricity sources. This drawing is at my community.
@@eltunene thanks
Water in itself is non-conducting. However the salts from the tap water make it so. Thus the byproduct of this process can include chlorine gas and other oxides.
You are absolutely right! That is why distilled water is recommended, please find an updated drawing at ruclips.net/channel/UCmjQnuJwV0FkjdEyi3099RAcommunity?lb=UgwRGRtRxJVb63bdsUJ4AaABCQ . Improvements such as adding a solar still for distilling the water, solar power for saving electricity, are shown in this new drawing. I have known of people using the hydrogen to power a gas refrigerator. No amounts nor dimensions are given in this new drawing, since its purpose is to suggest improvements which suit the user needs. I suggest starting small and grow the system from there, using the principle given.
Good presentation... but pl. Can you try to explain practically rather than theoratically?
To split 1 liter of water you need around 10.7 MC ( mega coulomb)
1 watt/ volt = 1 coulomb/second
If you use. 150W 24v power supply, you'll get 6.25 coulomb/second
That will take around 475 hour to fully electrolize 1 liter of water.
If 1 liter of water can contains 620 liter of o2, means you'll get a 620 liter of o2 in 475 hour. Approximately 1.3 liter per hour.
An oxygen concentrator can deliver 5 liter per minute or 300liter oer hour
If you want to get the same 5lpm flow, you'll need to multiply the power wattage to 300 times. Means you'll need 45k Watt
Wow! It takes a lot of power! Thanks for your contribution!
@@eltunene yes. You will have better deal by creating an oxygen concentrator. It can supply up to 15 lpm oxygen with standard household electricity. Harvesting oxygen from air and concentrating it to 100%
@@davidhutagaol4860 Well, for a small jewelry torch, buying an oxygen concentrator would be a little bit too much. But, yes, it takes a lot of power to electrolize oxygen from water.
finaly ,clear as water.
We need this in India right now!
Dear Richard Pagan, I just uploaded a video in Hindi (machine translation) please check it out and give me some feedback. People in India are very creative, they can improve the generator to suit their needs!
Fantastic 🙏👍
Dear friend, thanks for your kind comment!!!
But what material is the oxygen and H2 gas contained in the tank? thanks just help
Liked and subscribed .. thanks a lot for the information .
Thanks, Alien, for your kind comment!!!
Very valuable !
In these pandemic times...
Thanks, Chandana, for your kind comment!!
3:32 the word "i guess" threw me on the floor and made me laugh uncontrollably.
The intended word was "a gas", not "I guess". Sorry for the accent!
I think you also see it in RUclips captions 😀
stupid monolinguals...
Can it generate oxygen fast enough to help a covid patient ?
Dear Shirish, it can be possible to generate oxygen as fast as you want, however, beware, there are some other vital concerns. If water from the tap contains some foreign substances such as sodium chloride and other salts, as well as chlorine in solution, the oxygen can be badly contaminated by chlorine and other lethal gases. On the other hand, only a doctor can determine the rate the patient needs. Another high risk is handling both oxygen and hydrogen, if a considerable amount of oxygen is present in a room, virtually any object becomes violently flammable, such as drapes, fabrics, plastics, even some metals can burn in a pure oxygen atmosphere. Other than that, the bigger the generator, the more gases produced. Using stainless steel plates instead of screws, a bigger power supply and a bigger piece of equipment, you can get any amount you wish.
Hello, change the stainless steel electrodes to avoid Hexavalent Chrome, change them for titanium, platinum or graphite (the cheapest).
For electricity use a source with more amps like the battery of a motorcycle or vehicle, with voltages between 12v will give you good results.
Add a bubbler to the oxygen outlet to add moisture.
Be careful with the duct that carries oxygen, check that it does not have water drops because it contains caustic soda, it must be dry inside the duct.
Use distilled water to avoid impurities.
--------------------------------------------------------------
Hola, cambia los electrodos de acero inoxidable para evitar el Cromo Hexavalente, cambialos por titanio, platino o grafito (el más barato).
Para la electricidad utiliza una fuente con más amperios como la batería de una moto o vehículo, con voltajes entre 12v te dará buenos resultados.
Agrega un burbujeador a la salida del oxigeno para agregarle humedad.
Ten cuidado con el conducto que lleva el oxigeno, verifica que no tenga gotas de agua por que contiene la sosa caustica, debe estar seco al interior del conducto.
Utiliza agua destilada para evitar las impurezas.
Yes. Fast enough to burn his lungs.
This ^^^ or maybe in future on other planets where no oxygen is present 🤔
