- How to make a Hydrogen generator electrolyzer for a balloon, including what is an electrolyzer and how an electrolyzer works.
Note, using stacked plates as I did makes only a minimal contribution so you may as well go with one plate for each side. More on that analysis is on my webpage here:

So it was all fun, eh? Nice job on the video, you spoke well, kept it interesting with good explanations.
One of the best instructors I've ever learned from.
I want to make a big electrolyzer to inflate a small blimp so I can cruise it around the skies. Awesome video! 👌 👏
Me too! :-)
Your video is very well done and interesting.
Thank you
Wonderful informative video sir, thank you
Very cool and awesome demonstration!
Thanks Rimstar. I made a nice version of this before watching your video. had the same issues with corrosion, " pink water on the positive side. I used stainless and sodium hydroxide and the reaction stopped working after I left it run all night. It worked again after cleaning but not great once the steel degraded. I am going to replace the S.S electrodes with palladium plated titanium and see how it works using my new 100watt 13.5 volt power supply.
such a neat experiment, congrats
Awesome stuff as always! I’m not sure if you already know or if I mentioned before but, I’m The Pheuzitionist from before. You gifted the the Whimshurst machine and Cartoon Guide to Physics book a while back for helping promote your channel. It’s good to see you still making videos. I hope you have been doing well. I’ve been more on Twitch lately and only sometimes putting random things on CZcams here and there. I’m not sure if or when I might be as consistent here but, keep up the great work and stay awesome! 👊😉 Cheers!
Wooow. This is a very cool science fair project
Good, i love it!!!
Nice video!
Thanks! And thanks for your help on testing day!
It's a shame you don't make movies anymore. Were good. I like watching them.
I should have another one coming out soon, just a little more editing to go (though I keep saying that :-)).
The setup look cool, I did similar thing when I am in high school, I use pencil lead and vinegar instead, and I cut my dad old laptop charger for power. I tried using bleach before, it's go a lot quicker but later create a lot of chlorine gas. Super fun!!!
Cool! Thanks for sharing. I still think you're the real life MacGyver!
The quick and dirty method was nice🤣🤣
Cool, thanks! :)
Me: Yay! I successfully contained Hydrogen in a bag..! What now...?
Also Me: *tries to stick my nose into the bag to smell hydrogen*
explode it!!!!
Nice electrolyzer! regarding the pink water issue, likely it is bad quality steel, but, for optimal electrolization of water you only need like 2 volts, so running 13 volts probably does not help with electrode corrosion. That's why HHO generators have neutral plates, to act like a reverse battery, however that would mix the gasses. You could try 5 volts from a computer power supply, becaause it can deliver decent current. For that tho the resistance might be to high. To lower it I would suggest cutting the walls on the bottles and exchanging them with some sort of fabric, which would allow the charges to move, but not the bubbles.
Hmm... I was planning to make adapt computer power supply for another project. Good idea. We had thought of the fabric separator but I was going to try this approach first so I could do comparisons.
RimstarOrg comparison! Great idea! I always like when people do experiments with numbers and comparison and conclusions.
Can you do this to create oxygen to breath for a mood enhancer? Like they have those oxygen bars? Or are there contaminates in the oxygen that make it toxic?
I don't know how pure the oxygen output is. I certainly wouldn't take a chance with mine since the water became so contaminated.
I use salt water as an electrolite.
I also have made them with pill bottles real small reactors.
I'm trying to make one that's powerful enough but small enough to launch a model rocket I've already created one rocket but that was simply a water bottle that flew away very fast when It lit with my automatic ignition system I had set up.
I got about a hundred feet straight up
I think it is now nano coated at the left (positive site)
Chlorine gas.
I kept waiting for someone to touch a flame to the balloon. I was disappointed.
Me too.
Thanks.
you should have used the green bubbler for the o2 and the red for the flammable hydrogen.
Could this process be used for hydrogen cars? a drawback is lack of fuel stations so this seems promising
There are two types of hydrogen cars that I can think of (hydrogen internal combustion engine and hydrogen fuel cell). Both of them require highly compressed hydrogen (not sure on the actual pressure) to actually be able to run the vehicle for any length of time. So short answer is no, this would not work unless you had this setup to create hydrogen and compress it as well.
Yes, same hydrogen
No. Splitting the molecular bonds of the water apart takes just as much energy as it can produce from being burned. It's sort of like taking a battery to charge another battery to then charge your car battery, you can't get more energy out of it than you started with and you're just going to lose a lot of the power to heat loss like that. You could make hydrogen like this to fuel your car up but it's just going to use and waste even more electricity so if you're using fossil fuels to provide the energy for producing hydrogen to then power your car you'll just end up needing way more fossil fuels as a result. The change would result in a net loss and just produce even more pollution at the end of the day.
It is hydrogen though, so yes you could power a hydrogen engine with it but there's no point of doing that if your goal is to save energy and you'll never be able to split the hydrogen bonds with electrolysis then burn the hydrogen to produce electricity and somehow create a perpetual motion device by repeating the cycle. Burning hydrogen just causes it to bond with oxygen and releases energy as a result but breaking those bonds back into free floating hydrogen and oxygen takes just as much energy as it released to begin with sort of like stretching a rubber band and then letting it snap back or rolling a ball up a hill then letting it roll down. It'll produce the same amount of energy you put into it from stretching the band or rolling the ball uphill, same with burning hydrogen to produce energy then using the energy to split the bonds again, the laws of thermodynamics makes it impossible to produce any kind of perpetual motion device because all you're doing is adding energy into the system and then taking it back out, it can have only as much as you put in to begin with exactly like filling a cup with water then expecting more water to somehow pour out than you put in it to begin with.
"Let's do this for zero dollars" proceeds to cut up a 157 dollar garbage bin.
I'm not sure how much the garbage bin cost originally but it cost me $0 since I got it from the garbage. But yeah, the bun turned out the be chrome instead of stainless steel so for stainless steel I would have either had to get lucky and find a different one or buy some sheets.
Not bad! This is a project I've been tinkering with for quite some time as well with mixed results. The hardest part of this is always separating the gasses while also needing to have the plates as close together as possible. The best ways I have come across involve using fabric as a semi-permeable membrane which when wet, allows ions to pass though while keeping the gasses separate. See this video: czcams.com/video/K7DJGCF8Sj4/video.html
I think your design could benefit greatly from cutting away the plastic lying directly between the plates and then gluing a piece of nylon curtain or tablecloth in its place with epoxy. Also, I think stainless steel brillo pads might be just what you need in a positive electrode. They're dirt cheap, available everywhere, and virtually always actual stainless. They also have very high surface area compared to flat plates. I've not seen anyone else try them for this and neither have I tbh but I know they do work as electrodes in general.
Is there any way I can contact you? I have an important question regarding one of your projects.
Sure. You can email me at my email address which is at the bottom of all my webpages on my website rimstar.org.
It does not work
It's an image, you have to type it in. Here it is: stevend@rimstar.org.
@RimstarOrg i need help, im using a 12v 1.3ah lead battery things are happening on the negative side but nothing bubbles on the positive side, the positive side is corroding, and turning brown but nothing else happens, please help im doing it for class
Since the positive side is corroding, I wonder if it's not stainless steel but something else that corrodes easily. I suspect mine turned out to be chrome instead of stainless steel and that's why mine corroded and my fluid turned brown. Maybe your material is even worse than mine.
@@RimstarOrg its galvanised steel but the corroding is much worse on the red side
@@RimstarOrg and it seems to be bubbling way more, and my sodium hydroxide source is drain cleaner
do you think this could fuel a genarter if you converted it
Tre Savage yeah we could
It will be very hard but possible... A device with a mix of regular fuel and this electrolyzer will be more practical and achievable...
this guy reminds me of Mr. Wizard from TV.
so i tied a string to the bag so it won't fly away, lol i like his optimistic thinking
:) Yeah, I did almost lose it at one point.
Rimstarorg can u test if it can be used as a battery???? Like charge it first and contain the gas in a bottle, then remove the powersource charging it and test how many volts/amps it produces. And if it can power a light bulb
That's an interesting question. Bubbles of different polarity collect on the different plates so if you turn off the electricity, you'd think that would release the bubbles and there'd be a tiny, brief current. But if you mean, can you feed hydrogen and oxygen in and get electricity, I'm pretty sure the answer is no. For something like that look at fuel cell technology, which does sound a bit like what you're asking for.
@@RimstarOrg yep hydrogen fuel cell technology, coz I've seen a man with a store bought mini version of a fuel cell here on YT who charges it on solar and he then takes of the solar panel and then powers an electric motor with the hydrogen cell alone
Sir i have question on which side oxygen and hydrogen formed .
I mean oxygen formed on Positive side or negative side
Oxygen formed on the positive side and hydrogen on the negative.
From what I know you only need 2 volts to separate the water (closer to 1.8V) other wise the current doesn't do anything and converts it into heat.... If you still want to use a 12V supply just connect 5 more of this device in series...
I was surprised they needed a running car to drive this. When we are doing electrolysis for rust removal a battery charger is well enough. It won't go much higher than a couple of ampere, if that.
Low voltage high current does the job
if I put baking soda can it fly
Great project, did the car start afterwards :-)
It ran the journey home with only the electrolyzer as fuel ;)
Thanks. Yup. :-) The car was running the whole time so the battery wasn't drained. I wonder if it took less power than an air conditioner.
If you used a sealed H-shaped cell with only an oxygen outlet and a hydrogen outlet and not have anything open to the air, you could possibly get away with filling a party balloon if you also put a party balloon on the oxygen side to balance the sides. If too much water starts creeping up on the oxygen side, just squeeze the oxygen ballon slightly to balance the sides. But who wants to babysit it!! :) Nafion is the best way to go.
Sir can you explain how to make electrodes..??.. Can we use steel plates..??.. And how to use it.. Sir please help... Thnkyou
You'd have to use stainless steel plates. Plain steel plates would corrode. There are different types of stainless steel too and I don't know which is best. Either that or mine wasn't stainless steel at all. A long time ago I made one and happened to have the right stainless steel by luck and they didn't corrode.
Some other alternative plate materials include lead and graphite. Also, it may be possible (and considerably easier) to use stainless steel scouring pads (brillo) as electrodes. They are dirt cheap, available everywhere and have very high surface area compared to flat plates. Just don't confuse it for steel wool. The only problem is their high electrical resistance which can be addressed by connecting to them at several points.
JUST DON'T USE CHROME PLATED ELECTRODES
It will leech a toxic chemical, I think "chrome hexavalent" which will turn the water an ugly brown and is very toxic. It's also an illegal material to handle and pour down the drain or dump outside as it's very toxic and will probably kill any plants or animals it comes in contact with 😰💀
The water did turn brown so maybe you're right, they might have been chrome plated instead of stainless steel as I thought.
@@RimstarOrg Well the only way to be sure is to run a toxicity chemical test on the solution or check the steel through spectroscopy for any signs of chrome. But just to be safe I would dilute that brown solution in soapy water and just leave it in the sun to see if the suns radiation break anything down.
Awesome experiment. Any plans to build a hydrogen weather balloon?
Thanks. That's the Hack613 group's plan. They'd like to send one up to the edge of space. I made this as a sort of preliminary experiment.
Have you had a chance to do more with your robotic snakes?
That would be interesting. I was unaware of Hack613 before this video but it would be good to visit one of their meetings while I am in Ottawa this summer.
I have tinkered with a new joint mechanism for rolling up pipes/trees but progress is slow due to other commitments at work. I'm also thinking of testing the snake with smaller sg90 servos in an waterproof sheather for an underwater eel, although I am yet to do any buoyancy tests.
Awesome! Good idea going smaller for the eel, you can test in a bathtub.If you do go to a Hack613 meeting, let me know and I'll go too. With two meetings a week, I don't go every time.
Can we put ballon instead of plastic bag
I didn't use a rubber balloon because I figured the pressure of the hydrogen production would be too small to expand the balloon. My guess is that it would have just found another path instead. So I used a bag which didn't need to be stretched in order to inflate. So I have my doubts that a normal, unstretched balloon could be inflated this way, though I could be wrong. If your balloon doesn't require any stretching then I don't see why it wouldn't work.
I use a PEM electrolyzer (fuel cell in reverse) to inflate balloons. You can generate a lot of pressure with those. But you could also fill normal balloons with a similar setup to Rimstar's. He used bottle tops that were just open on the bottom though. In that case, the pressure from the balloon would just force the bubbles out of the bottom of the bottle top. If you used a sealed system, you could collect the hydrogen in a balloon. But, you would have to put a balloon on the oxygen side as well or the pressure from the hydrogen balloon would just force the water down and out of the electrolytic cell and right into the oxygen bubbler.
That thrash can probably was made from cheapest ferritic stainless steel (if it even has enough chromium to be called "stainless"). That can be easily tested with magnet: it should be strongly ferromagnetic, while proper austenitic stainless is usually barely magnetic. Also making electrodes from multiple parallel plates in configuration like that is not improving anything: there's no electric field between plates of same voltage to move ions.
Alexander Mishunin true. There's plenty of youtubers making vids they have very little Understanding of.... I unsubscribed
Interesting. I just did the following. I used a different needle each time.
1. I held a neodymium magnet against a trash can sheet to magnetize an area of it and then the area lifted a needle.
2. I tried lifting the needle using a sheet I hadn't magnetized and it didn't lift. (Done as a control.)
I repeated steps 1 and 2 with a stainless steel knife and had the same results. To get the magnetized materials to lift the needle, I had to touch the needle so I couldn't tell if the trash can became magnetized more strongly than the knife.
Regarding the mulitple parallel plates not having an electric field between the plates, I have to question that. The spacing here is pretty big, not exactly a good faraday cage. Also, it's hard to know for sure but check out Thomas Kim's video here czcams.com/video/gZJEDe_HUcw/video.htmlm14s. It could be the bubbles are all coming from the bottom edge but it's not clear either way. I'd need a top view and to compare the number of bubbles coming from the outer edges compared to between the plates.
Edges of internal plates may still kinda work up to depth of something like distance between plates. "Bottom edge" effect may be a consequence of another problem: if electrolyte resistance is high then electrolysis is happening only at the very bottom edges of plates (where current travel distance is lowest), and it seems to be the case, since, as someone already pointed before, voltage needed for moving electrons from oxygen to hydrogen is 2. volts. I think if sheet metal was shiny enough it can be seen where current was passing through by discoloration at anode.
Oh! @Alexander, good idea. I still have the electrodes but not where I can easily get at them. They were definitely discolored so I just have to get them and take them apart. That may give some hint as to whether or not stuff was happening to the plates in between. It may take a day or two but I'll get back on that.
Alexander, I took apart the electrodes and did an analysis. The evidence indicates you're right. The three inner oxygen plates (out of five plates) were discolored at the edges only. The discoloration was rusty brown. The hydrogen plates were similar except black. However, the three inner hydrogen plates were also coated in rusty brown on all of their faces. My guess is that this was from rusty brown fluid which came from the oxygen plates.
Hmmm... But why didn't the inner oxygen plates also have a coating for the same reason. Darn. There's still some mystery. Maybe the rusty brown particles in the fluid were positively charged?
Anyway, analysis photos and write-up are now at:
rimstar.org/science_electronics_projects/hydrogen-generator-electrolyzer-for-balloon-stacked-plates.htm
In future I'll try with single plates, no stacking.
Plzzz sir teach me how to make dc negative ion generator 12 volt for magic of electric touch
Can we produce sufficient hydrogen to do serious work
if you have a better method to collect the hydrogen gas, such as slim plastic bottles (reasonably thick) or syringe type containers, you can collect it that way and yes, you can create enough H+ to do serious work, it really matters what's powering the electrolyzer that determines the rate H+ is created. Hope this helps!
And if in the HHO Generator pour alcohol 90%?
basically nothing happens
Is it possible to use a balloon instead of a plastic bag?
The problem with a balloon is that the balloon needs to be stretched in order to expand. That means you need a lot more hydrogen to create the high enough pressure to stretch the balloon. The plastic bag I used didn't need to be stretched.
@@RimstarOrg since the hydrogen comes out as a liquid i think, can you put it into a small tank that becomes high pressure when it vaporizes?
The hydrogen comes out as a gas. Otherwise what you suggest would have worked.
Why 2 flame arrestors?For the hydrogen side I understand, but why for the oxygen side?
I guess in case there's any hydrogen in that side too.
I don’t think the hydro and oxi are comming the water as water does not conduct electricity. It comes from the electrolizer and breaking down of the cathode and anode. I would like to see you test the gas with different electrolizers, in essence proving water is not h2o..
You're right that pure water doesn't conduct electricity. That's why the sodium hydroxide was added, that makes the electrolyte conduct electricity.
RimstarOrg well I think when you desalve the sodium hydroxife in water the water breaks it down taking care that the sodium ions conduct the electricity. in my opinion the gasses come from the Sodium Hydroxide not the water. Some may come from the electrodes depending on what matarial you use (the impure stainless). So lets test the gasses comming from different electrolytes to make sure the gasses come from water or electrolyte
We can also create the gases we need batteryless simply by using aluminium foil and sodium hydroxide and walah! Batteries not required
We did that afterwards with the leftover distilled water.
fidel catsro But that doesn't give you oxygen, incase you want to make some HHO, and it also releases irritating gases.
hehehe i never claimed i was a chemist...
Even real stainless steel would not have been of any help. Only Platinum or gold electrodes (or cladding of these two metals on an appropriate substrate) will completely resist electrochemical corrosion and yield oxygen only. Carbon electrodes may be used but will wear off and form a cloud of carbon particles.
That is not entirely true. In sufficiently concentrated sodium hydroxide, nickel electrodes can work as an anode. Lead will work fine if the electrolyte contains sulfates and not much else. Several oxide anodes should work sort of fine too, at least as good as carbon. I am not sure about gold, I've never seen a succesful use of it. It is not as inert as platinum, I guess. And there is boron doped diamond, but that is probably too expensive.
If some wear is ok, copper may be fine, as from my experience it forms a thick sludge when corroded electrochemically in alkali solution, that sticks to the electrode (and forms beautiful green mix of copper compounds when exposed to air for long enough). On the other hand copper in NaCl forms a fine suspension of Cu2O. If you want some green pigment or copper (I) oxide, you may be able to kill 2 birds with one stone.
Do you have an idea of how pure the hydrogen is? As in how much oxygen accidentally mixes
Nope, I don't have any idea how pure it was. Given that the tubes are not really airtight, I'm sure there's normal air mixed in.
as long as the balloon flies, it doesn't matter
@@gulshanchaurasia2233 yeah but i'm not planning on making balloons, and when you pressurize hydrogen it can be dangerous to have oxygen mixed in
@@hansvangrunsven2073 what are you making, bombs? You would see droplets of water if oxygen mixed with hydrogen.
@@vassilyknigge850 No you wouldn't, it only converts back into water if you bond the hydrogen and oxygen back together by burning it. It releases energy in the form of heat when it reforms the bonds so if what you were saying was true then the hydrogen gas would just spontaneously combust upon coming into contact with oxygen...
why do we need add something to water? if H2O gets divided into H2 and O, then shouldnt it work even in pure clear 100% h2o?
My understanding is that it's needed because pure water doesn't have enough charge carriers or ions. The thing you add makes the water more electrically conductive.
You could try without adding anything but it won't work as well.
@@RimstarOrg Thank you!
Can i use baking soda
I'm pretty sure you can't use baking soda. That will turn it into an electrolytic capacitor instead. You can use salt though.
@@RimstarOrg That Will create chlorine gas.
@@sa6kod154 chlor alkali process
Incorrect, you can and should use Baking soda its Cheap and very good. Adding salt is Bad it will produce toxic chlorine gas instead of oxygen.
This might be dangerous. Why would you expect the anode (oxygen side) not to oxidize? Stainless steel contains chromium, and hexavalent chromium is a carcinogen. You probably don't want to dispose of the pink stuff in the sewage or environment. If you want to be on the safe side, use a sacrificial anode, for instance rebar steel, or use an inert material like graphite (or platinum) if you can get you hands on this material.
I'm no chemist and so I tend to stay away from chemistry... but I worked with an electrolyzer for around 3 months a decade or so ago. The electrolyte was potassium hydroxide (IIRC) and distilled water and there was no visible oxidation, corrosion or discoloration of the electrolyte and it was in use for hours each weekday. So that's one reason I expected the anode not to oxidize.
Also, Alexander Mishunin below mentions it might be because my metal was made from the cheapest ferritic stainless steel, so I guess there are different grades.
Theo0x89 There is likely no hexavalent chromium isn there, as that would make solutions yellow. Instead the solution becomes pink what suggests formation of ferrates, which although strongly oxidising, are not very stable and quickly decompose into iron hydroxide, which is harmless. Although the solution is strongly basic, that is not a problem, as the sewage system is able to deal with ist all the time-sodium hydroxide is a drain cleaner.
Easier and cheaper method of getting large amounts of Hydrogen gas fast. Just put aluminium foil in a sealed container with sodium hydroxide solution. A used fire extinguisher is ideal but purge it of any air before use or the resultant gas will be flammable having both oxygen and hydrogen in the one pressure vessel making it a bomb. As the pressure builds you can fill balloons like you would be able to from a helium tank. The difference is that the balloons will be flammable if exposed to fire or an ignition source so beware. Hydrogen is actually lighter that helium so your balloons will float way better too.
👍
Aww man I really thought you were going to hold a lighter to that balloon
sandpaper electrodes gives better surface area
Thanks. I was worried about scratching off the stainless steel coating, if there is such a thing.
need a bubbler if you pump with air because hydrogen explodes if you add preasure implodes when you have it like your doing another trick is steel marine cable more surface area theres some dangerous videos somtimes involving fridge compressors but you can cook with it or vaporise metals carefull vaporised steel gives of nitric acid same as welder the worst acid ?also carfull iff you add different preasures together but you must read a bit aveagood one
may i ask what role play those two bottles with water out
The two bottles are often called bubblers or flame arrestors. The idea is that if there's an explosion in the balloon then the fire will not be able to get back into the electrolyzer because the flame can't go through the water in the bottle. I probably didn't need the other bottle on the oxygen side though.
Don't use salt it produces chilirne gas
If you put salt instead of sodium hydroxide would you get chlorine instead of oxygen
I'm not sure but my guess is no. The sodium hydroxide doesn't get used up, only the hydrogen and oxygen atoms which make up the water. So the same may be true if you use salt. But I'm no chemist.
Hi chemist here,
You will produce both chlorine gas and oxygen on the anode side if you use sodium chloride. You can use sodium carbonate (soda ash) or sodium bicarbonate (baking soda) instead, but you will also produce carbon dioxide with the oxygen.
The better option is Borax (sodium tetraborate decahydrate) the laundry booster. It will provide the needed sodium, won't produce any borate gasses, provides a buffering capacity between ph8-ph10, can prevent bacterial and fungal growth if you want to let the water sit for longer periods while not running, and is relatively non-toxic (you still don't want to drink it) and can be poured down the drain.
@@DRS8503 I hadn't thought of using borax for this. I'm definitely going to have to try that next time.
Another suitable electrolyte which springs to mind would be trisodium phosphate, often sold as "TSP" where ever painting supplies are sold. It's highly soluble, stable and cheap while also being relatively safe to handle and discard.
@@DRS8503 would it be bad to use the oxygen as a ..how to explain..like mood booster? or to get more energy by making the oxygen this way and breathing it? Or would there be dangerous gasses on the oxygen side also?
I wonder if he even knew that he was using the tin snips wrong...green handle snips are for the left hand.. Red is for the right hand...and yellow is straight..and small (scissor part that does the cutting) yellow handle is called bull nose.. For cutting thicker stuff that is hard to cut with regular snips..
First off, I have only green handled ones so I make do. But the green and red colors are for the direction of the cut: green are for straight cuts and cuts to the right (clockwise) and red are for straight cuts and cuts to the left (counter-clockwise).
It's port and starboard not left and right
And they, who ever they are, say it's to hard to do this and that's why there are no cars running on hydrogen. Someone is lying.
Thanks for the video
Limited amount of water.
Hydrogen does actually pose some tough engineering challenges. It's a tiny molecule, so it's harder to contain, and is also extremely flammable meaning lots of precautions need to be taken in transport and storage. Not unsurmountable I'm sure.
It isn't hard to do, it's just inefficient. Making one Kilogram of Hydrogen and compressing it to 700 bar (for use in an automobile) would take 100 kWh of electricity. You'll go 75 miles, but a Tesla electric car can go 75 miles on only 30 kWh of batteries.
Hydrogen doesn't get used because it's more expensive than other forms of fuel. Electrolysis is very inefficient, the hydrogen's hard to store, and we don't have enough engines that can run on it to make it worth our while.
There are special cases where hydrogen makes sense. Iceland, for instance, has a huge fishing fleet, tons of hydrothermal energy, and no petroleum resources. So they're in the process of building hydrogen plants so that they can stop importing diesel.
Hydrogen production is also a possible use for certain types of green energy (solar, wind) where you can't just scale up production to match demand. If the wind is blowing but the demand for electricity is low, why not produce hydrogen? We're still at the design and planning stage for that, but it's something to look forward to in the future.
It takes a lot of time and money to build an industry and a market from scratch. We're probably 10% into that process with Hydrogen. Give it two or three decades and you'll probably see it around a lot more.
Edit: typo
@@jeffspaulding9834 Hydrogen generators will never be used large scale, it takes just as much energy to split the hydrogen/oxygen bonds as you'll get from burning it, sort of like filling an empty cup then pouring the water out, you'll never get more energy than you start with but you'd also get a lot of heat loss and several other forms of inefficiencies to lose energy along the way as if you were spilling some water every time you converted it.
We might make a few hydrogen storage systems for like you said, overflow from excessive production when demand drops from things like solar panels or wind turbines with nowhere else to store it but it would mainly just be battery banks for excess. No way we're ever using it for cars on any real scale because it just uses more energy than just running the car directly from the electricity you'd otherwise be using for generating hydrogen with electrolysis.
Hydrogen combustion temperature 2000 degrees celsius
Don't forget it )
Wiki said it's 500°C hmmm
it's a ignition temperature )
in mix with oxygen you can reach 2500 degrees
extremely flammable and dangerous gas
just be very careful especially with sparks when you connect wires
Yum yum fuel for my bike engine
Almost zero $157
A filipino used this method to make fuel for the cars.
Yeah but it doesn't work.. en.wikipedia.org/wiki/Water-fuelled_car
Well, maybe it's just good for entertainment. Not for machines.
thank you . i made one before with no flame arrestor. it was a small device i new it could explode..it did. was a safe explosion and exiting...use a arrestor or else i can kill you. great video thank you!!!
Ok I'll use a flame arrestor plz don't kill me Stephane :p
Use polithin plastic bag as balloon save earth
an easier way to make hydrogen is with aluminium and dish soap
The other guys with me did that while I did the electrolyzer approach. We had a lot of fun. I went with the electrolyzer approach because many years ago when I did it with proper stainless steel plates, the fluid was reusable, you only had to add more distilled water and it remained clear. I was hoping for the same reusability this time but the plates were wrong. I didn't want to do the aluminum and dish soap approach myself because the fluid isn't reusable.
Dish soap? Clearly you've never made hydrogen.. or done dishes.
Hydrogen gaazzzzz!

You made a hydrogen balloon and didn't put a match to it?!
:) I knew people would want me to, but it was a public park and I didn't want to scare anyone with the loud bang.
Hahahahah
You should use sand papper to scatch the surface of the stainless steel plates to give it more surface area.
ELI5 why sandpapering the steel plates give it more surface area?
Because why would a flat surface have more total surface area than a scatched and rough one?
I thought I had corrosion resistant materials i.e. stainless steel. It just turns out it wasn't.
RimstarOrg better luck next time.
Rick Sanchez thanks for the info

， 😜 I think your electrodes are not straight
Ever lit hydrogen on fire?
I've lit HHO on fire, never pure hydrogen. The electrolyzers I worked with in the past didn't separate the hydrogen from the oxygen.
Well what you lit, then, was far more explosive! One can shatter their ear drums lighting a hydrogen-oxygen mixture at close range. Pure hydrogen needs to react with the 21% oxygen in surrounding air and is much less explosive.
Can you make more video fill balloon
much better than anything any indian can try to make.
Dats waaacist!
