Can this please be done again ? Years back(like 5 years ago when i was 15 ) i did this and let me tell you i did blew a lot of baloons up with that gass 🤣 you only need to do it the right way.
Salt
Hydrogenics makes hydrogen from water as their source of revenue in Germany, Adam Savage, renounce your title as Engineer you are no longer credible.
You need my Pure Water to get anywhere watch my Video
FUCK YOU YA DISHONEST ASSHOLE!
"Volts of power and watts of energy" - I died a little on the inside
As an electrician...same
Found the electrician
Good catch 👍
and running more than 2.5 volts through each plate only produces more heat LOL so 22v is kind of funny
and electrons travel in a least path of resistance so all that is going around the plates
this whole video has to be a joke, you guys must know better :)
Resistance is futile;-)
Did you guys realize the major flaw with this design yet? I know this is 4 years old. Your electrodes were WAYYYYY too far apart. Surface area is only one part of the equation. The other important factor you need to consider (in order to get the cell to draw more amps) is the distance between the anode and cathode. And a high voltage / low current solar panel isn't the answer. You want to get the plates SO close that it only takes a couple volts to split water and will pull MANY amps at that voltage. Those 100 watt solar panels would work but it you would need a buck converter which uses MPPT technology to lower the voltage and boost the current. Theoretically, at peak power and (to keep things simple, let's just say) a 100% efficient buck converter bringing your 22 V from that 100 watt panel down to 2 volts, you could make 1 liter of hydrogen in less than 3 minutes. So you could get your 15 liters in only 40 minutes from that 100 watt panel. In reality, with losses, say an hour or so.
seriously thats what I was thinking I'm dissapointed I didnt see them do something like that.
yes, or use neutral plates in between but then it would mix H2 and O2 and it will be hard to separate them
the electrolytes need to move between the plates, and that big U is too big for dem smol ions
Exactly. Should not be more than 2v per cell. The excess voltage only produces heat.
Hey brother,
I would like to ask if you have any blue print or a design I could use?
😅😅🎉🎉🎉😮😮😮😮😮😅😅😅😅😅😅😅😊😊😮😊😊😊😊
"we tried almost nothing but it just wouldn't work "
Potassium hydroxide is the key.
Acid citric and koh...and resonance frecuency match with electronics
@@renleedativo1679 : Sodium hydroxide & aluminum (with an after bath) works pretty well too.
@@cobbjtn titanium is good with acid but worst with electricity...only if you can covered with platinum or rodiun will work
I made one of these in my living room years ago, and produced a steady flame; with small plastic spacers and large steel washers. I used ac current but a variable dc amp multi plug selector. 12 dc amps in my mason jar produced enough steady hydrogen to burn.
They are completly wrong. You produce the most hydrogen and oxygen when the voltage is low and the amps are high, thats why it doesnt work
Thank you for mentioning it. Eventually, someone who knows something.
Well I wasn't trying to sound smart;p This info is easily obtained on google, i don't get why they messed it up. I think that either Adam or Jamie should've known too, they have been working with electronics for ages.
Where is your video? I see a lot of commentators saying they know how to do it but I don't see any of them doing it, I call BS!
My grade school science class said if you double the voltage, you double the current.
Not when using a solar panel, generally. Unless you use a bigger panel. It takes a very big panel to put out the needed amps, even with high volts.
Wow, this is shockingly full of miss information. "22 Volts of power, 100 watts of energy." "The more voltage you run through, the faster that process happens." Nope... Nope... SMH
I’m confused tho because the higher the voltage the more work done per unit charge and more work done should mean that the process should happen faster what’s wrong?
@@anonymoushimself1540 hydrogen splits from oxygen when it is exposed to 1.23 volts, when you have 100 volts its not going to be faster then with 1.24 volts
Who is Miss Information?
Those plates need to be much much closer together... Like a spacing of 2 to 3mm works best. And you need to add an electrolyte like sodium bicarbonate.
I agree, or pottasiam Hydroxide. Mine is about 1/4 of the size and does 2lpm of hydrogen.
I'm very ignorant here and am not finding the answer (Probably cause I'm asking the wrong questions) but how quickly is the electrolyte depleted?
They added potassium hydroxide as an electrolyte. Left and right sides of the cell should be brought closer together but plate distance makes little difference
BUT, you don't want capacitors or you need some sort of faraday cage.
SMH Power is Watts not Voltage (voltage is potential difference), this is basic stuff here... They start with saying the process is done by running current(Amps) through the water but then they have 100 Watts 22 Volt solar panel which is just under 5 Amps of current compared to a car battery's 500 or more amps. Not to mention having a higher voltage actually gives you a lower current rating (ohms law) but hey lets F up the experiment in the name of clean energy. There is so much wrong with this I'm just scraping the surface.
uh.. mine runs at 12 volts at 7 amps... lil 4" cube dry cell..compared to a car battery huh.. pretty sure only a forklift batt is cable of 240 amp draw.... highest most expensive car batt says it right on the label..
90 Cold cranking AMPs.. sorry dude, I'm a Gmac even our fucking plasma cutters dont take 240 amps to cut through 8 inches of steel.. oh gmac is gas metal arc welding... engineer at work :-\ your pretty close volts x amps = watts
Blasted 🔥
they shouda attached a bicycle power supply and made that guy sleeping on the chair power it
Adam is great, so was mythbusters, but scientist he is not.
You can get a hydrogen generator working on 5 amps, but with the giant U shape, I think the resistance is too high. I am barely getting 5 amps draw using 30 volts, salt (not KOH), and like a tenth the distance. Also, filling a balloon takes a lot more hydrogen because it’s so compressible
That bag is too thin, lots of gas slips out.
+minihjalte Maybe Mylar would be more successful?
+minihjalte
Actually I am think about a water trap to collect the gas..
what they did to collect the gas actually surprise me lol
+thegreatMSG Grant made a water trap on Mythbusters to trap Nitrous Oxide for the Confederate Rocket myth. Looked like it worked well.
+minihjalte Which is partly why Hydrogen fuel cells are such a bad technology for many applications, the hydrogen is very difficult to pressurize and then store, compared to just pumping electrons into batteries.
+hallis1 NO2 molecules are *way* bigger than H2 molecules.
"22 volts of power, 100 watts of energy" - *physicists cringe*
I was gonna comment that. I hate being a corrective asshole but it really made my toes curl when he said that lolol
@@southern7766 22 VOLTs of EMF*, 100 WATTs of POWER. If im wrong please correct me cause im trying to learn physics for electronics.
🤔 ohm's law 🤔
And didn't they say earlier in the video output is dependent on amperage, then later said voltage?
100watt at 22v = 4.5A lol throw some more panel we need more amp than volt
@@buder5116 volts aren't power and watts aren't energy
WE NEED YOU TO REVISIT THIS!!!
We want to see separate Hydrogen and Oxygen generator w/ useful compression storage
Modern german U-boats use this system: Sea water becomes Hydrogen for the Engines and the Oxygen is used for fresh air on board!
Those ingenious Germans! They still have U boats cruising about the seas? Don't they know the war is over?
@@kitemanmusic Well even the Cold war is over, but still are many american and russian nuclear submarines, with enough nuclear warheads to destroy the world, out there?!
So what's exactly is the diffenrence here -.- ^^
it is so slow becaus the plates are to far appart
you need rediculus amounts of current for that to run efficient
there needs to be less water between the annode and cathode
Not just that, the power supply could only produce 100W theoretically, not angles correctly and not in the sahara, it would produce maybe 3 amps or so. In that respect a car battery can generate much higher currents.
true that
+robot797 Will even says to space them with washers but they used nuts instead
ranwolf76 yea nuts will conduct better
to bad they did not try to improve this device
+robot797 totally agree a decent car battery will put out 750 to 1000 amps. I dont know why they are so intent on saying hydrogen generators dont work. they did the same on myth busters. obsered
Why do you guys keep debunking this?
It's been proven to work.
Are you purposely doing it wrong?
idiots busters
They need the volts because the electrodes are just too far apart. They should have used 1 tube with plastic plates separating the gasses so they can keep the electrodes as close together as possible.
If it worked, why wouldn't you use the hydrogen produced to make more hydrogen? Because it doesn't add up: just use the power input (e.g. solar power) to fuel whatever you need to fuel instead.
agree, they are hiding something, enjoy your negative ratings you know the reason. Plz build a correct generator and show it.
U neex 30 amps i been using hjo for 2 yrs i know all abouy thos shit bro LMAO
"22 volts of power, about 100 watts of energy" i physically cringed
If the current from the solar panel was 4.5A then with 22 volts you would have 100 Watts of power.
9:19 lol you can see the anger in Adam the moment they say, we used clean energy to do it, and he realized they failed it on purpose.
ohhh you can. hes probably thinking "how can i get this guy off my show"
@@twig4661 "you're fired."
Clean energy wasnt the issue....the issue is they didnt use enough....the amperage matters not the voltage. You only need 1-2 volts for electrolysis, but the more electrons you force through the water the more hydrogen you release and that means more amps
@@jerometruitt2731 electrolysis is most efficient at 1.22 volts. "more volts is better" smh
@@Grahamaan27 when did I say "more volts is better"? Learn to read, then comment.
That bag is probably leaking hydrogen like a sieve. Hydrogen is the smallest atom in the world, and it leaks trough most things. So a thin plastic bag is not the way to collect it. Use some sort of solid tank and a bubbler. And the tubing is probably leaking a little to so use som copper pipes to leak as little as possible.
lol
they probably kept the amps low so it wouldn't produce HHO in the first place
This is exactly what I was thinking. Those bags are super thin and have tons of microscope holes in them that hydrogen would leak right through super easy. Plus the rate at which they were producing it was very low. And in the end they didn't even try to explain why it didn't work.
There was a lot more gas in the bag than in the balloon SOMETHING DOES NOT STACK !
A plastic coke bottle would have held the H2 a lot easier than the trash bag. put water in it and have the water get pushed out as the hydrogen fills it up. This was a really bad example and to me was set up for failure.
This project can be improved! The gap between the cathode and the anode creates a big resistance, I think that the poles need to be more close to each other.
Much, much closer together! But that makes it harder to separate the O2 and H
@@adamframe309, This was extremely disappointing! That project was a very simple one, of which many people have already done. This looks like an attempt to make it look impossible. I thought these guys were smarter than this.
Non needed if you use frecuency match with electronics and a inductor equivalent...like a tank circuit
@@eloycastillo4191 Could you explain a little more? I've thought that with frequency and magnetism, someone should be able to elongate and help pull the molecules apart. So very little power would be needed to break the bonds. Or less anyway. And therefore less heat would be generated. Just something I've been kicking around my noodle. What are your thoughts?
Also, add potassium hydroxide as a catalyst.
Way to (once again) create an incredibly poorly designed/underpowered strawman to knock down. You guys make it look easy!
Wow these two guys do NOT know what they're talking about hahahahaha!
Who knew, voltages can flow through water!? hahahaha
5:41 oO ?
Pure water is not a conductor. Impurities in the water make it a conductor.
@@willdwyer6782 you actually want distilled water mixed with salt so that its only conductive with no other impuritys so you only get hydrogen and oxygen.
For the purpose of breaking water molecules, sure it's not conducive enough.
But if water were not at all conducive we wouldn't have the idiot warning labels on things like hair dryers.
@@burntchickennugget191 NOOOO, Salt is the worst impurity, it will make chlorine gas.
I see now, after finishing the video, why there are so many dislikes.
Gee
Problem one, you poured in an electrolyte after filling with water and did not mix it.
Problem two, the electrolysis current had too far to travel around the tube. It would have been better in a single tube with a partition in the middle.
The King of Random unit worked perfectly because there was not an Olympic Swimming Pool distance between the Positive and the Negative
+Paul Jacobs I was thinking the same. I hate it when idiot people perform tests without doing proper research first.
+Giyan Vice There is an ever growing HHO movement out there, but unfortunately there are so many self proclaimed experts on the internet that really have no idea on what they are doing.
Adam has now twice made ineffective HHO units, and published the videos.
I would like to invite him to do a third video, but this time actually take the time to research what they are doing. www.reduceyourfuelbill.com.au/forum
Totally agree...I think that this is intentional...reminds me of the Top gear Tesla saga...I am working on my 7th prototype now...and its not rocket science...you can make a hydrogen generator from as little as a paper clip and a straw, efficiency is where the attention to detail comes in.
Paul Jacobs Because all people going to drive own car on hho genrator what about crude oil mafia they will kill you read wrold history of creator who creat the water kit for car all is Dead or disappear
you just need more voltage than 22v, maybe mains 120-240v or even higher possibly, rectified ofc.
Lol! 8:20 Dude in the background with no worries taking a nap in the shade. "Electrolysis is exciting kids, better than watching paint dry."
Really interested in "Phase 2" of converting Adam's shop. "This hydrogen powered impact can do twice the torque for half the weight! AND all my fingers are still attached!"
i'm going to go ahead and also board the complain train. Every time i see somebody do this for a large audience or on TV, they do it wrong seemingly on purpose. I have build a rig like this with TKOR's design and got way better results with a way shabbier rig than than the original.
Did you also noticed how the Pushed Commercially Buying the fuel at the end of the video... So obvious they failed on purpose. What a joke.
I feel the same way. This was a deliberate attempt to make this project a fail.
I like the quick build idea and it looks cool.
Just a quick safety note, although the typical logic when working with bases (KOH) is to add acid to neutralize it, it is much safer to just rinse with lots of cold water.
Acid-base reactions generate a lot of heat, so the last thing you want when you are getting a base burn is to add more heat (that will burn you even worse).
WROOOOONG! the trick is AMPERES not voltage, this video was made to fail on purpose, i hate this kind of "shows"
correct
That's right
This vidéo was maded to break this idea
@Don Diego can you show us how to build a real one. Pls. Im trying to make my bycycle run off of hydrogen by decreasign the fuel ratio to a drip rather then a flood to be safe. I need some help plssssas!!!!!!!!
True
I bet you they're paid by big oil companies to try and discredit hydrogen-powered fuel cells like these look up the geek power engine seriously don't do anything
Starts with how hard could this be I did it in high school, ends with screwing up something my high school teacher used to do when he was bored.
I have made one of these myself and I know they work. the trick is getting the correct current to provide enough output to run an engine otherwise it's just a novelty item.
How do you control the watts and amps if just hooked up to a battery
never, ever, ever use fucking glove on a press drill... one day you will broke your hand in 3 place, if you're lucky.
+mrmadame28 i guess spinning plastic parts was hurting his delicate hand :D
Octahedron lol!
yeah I learned that the hard way, not with plastic but with steel, 25 stitches in my left hand.
+mrmadame28 Why?
Dobimar von Niebelschütz try to use a drill with tissue, you will see that when the drill bit touch the tissue, it grip very tight instantly. That kind of press drill is very strong. If you wear glove and, for a reason or another, the glove grip on the drill bit, you wont stop it, it is too strong. The way a glove tightens around you hand give a very good distribution of stress in the glove, therefor a working glove will not tear, it will make you move. Last time i see that happen, the guy have broken 3 bones in is hand in 2 seconds. And the press drill was equiped with a kill switch (a pedal that you have to press on to make it work). There is more dangerous, like a machine tool, those can litteraly snatch an arm...
And it's the amps that create hho. not the voltage..
The voltage drives the amps.....
If you know how to do it, where is your video? My grade school science class said it you double the voltage you double the current.
Kevin, where's your video, since that's what you're asking everyone.
Also, it seems you never made it past grade school science if you think doubling voltage will double amperage.
Xander Zoolander
I'm not the one saying amps creates HHO, so no need for me to build anything.
Current into a fixed load doubling with Voltage is a law of physics, did your school teach you something else?
Kevin, you've asked at least 3 commenters where their videos are, when you don't have one yourself. Where's your videos to disprove their claims and ideas?
Doubling voltage would double wattage, but not amperage; and vice-versa with amperage doubling. The only way you can get double voltage and amperage is if you quadruple the wattage and regulate voltage and amperage to where they are double their original value.
You're a hypocrite, and you don't even know the basics of electrical engineering.
Shame on you guys for being intellectually dishonest. Thanks for nothing Toyota and Tested!
Huh?
Don't blame Toyota. Blame the two incompetent people who built this ineffective HHO generator.
At the end of the video they admitted their method is not the most efficient way. The didn't say it's not possible.
its kinda funny how they made the video EXACTLY 10 minutes
probably for that extra ad revenue lol
@@davidmartin1628 can someone recommend a efficient h2 generator

+Arctic Gator well why I like these videos is that first I learn new "how to" stuff. Second is that for me to buy all that and build it would mean a lot of time effort and money to put in to it.
Personally I think its better to spent time watching DIY and "hot to make" videos on youtube than spend it watching some tv show or series or some crappy movie...
+Arctic Gator I would totally rally behind the "Procrastinators unite!" battle cry, but it sounds like too much work. Can I do it tomorrow?
For some reason when my professor did this in collage, he used two differant types of alloy. I believe one side was brass, the other was galvanized. If anyone reading this knows what alloy is negative, which is positive, and what type of alloy goes to each, posting it here will be helpful. Thanks to those out there with enough brain matter to do something usefull in life.
You'd want the galvanized as the side that would oxidize (+) and the hydrogen side doesn't matter what metal very much at all as no metals react enough with the hydrogen formed there. It's nice to use two metals that are very different in appearance in a class demonstration.
I love this. Adam takes two engineering students(im assuming bc Ive been wanting to build this too) and has them build something in his garage as he does his own business.Except these gentlemen have built a devide that separates the hydrogen and oxygen, further building on the foundation TKOR made. Excellent work Mr. Savage.
Yeah, except not really. They did a really poor job and made a much worse product than the original one. Their problem is that they put the nodes way to far apart from each other, resulting in a high electrical resistance and a very low current. To make HHO you don’t really need a high voltage, you need a high current.
Also I have serious doubts that this contraption actually separates the hydrogen from the oxygen.
Is like, yeah let's do this electrolyzer completely wrong "again" just like in mithbuster and "again" say it doesn't work like it should.
exactly what i was thinking
i think they are paid form someone or somewhere to promote that it is not working same like mithbuster.
but i already made one cell out of garbage and it produce more and i am happy that with more effort you can make it work,
these people are liar,
+majid majeed for sure
Yeah exactly. Disinfo for sure! Plus the asian guy made his people look bad by not knowing wtf he is talking about. It looks like they did about 5 mins. of research.
If they would have said, It dosen't release as much kinetic energy as what would be demanded, they might have legitimate claim, but it's ironically fortunate that one cannot produce hydrogen to easily; booom.
I always have to chuckle when I watch these two guys build something. I see them pointing at sketches, using tools and sounding (trying) like they know what they're talking about but, for some reason I get the feeling Adam is always standing just off camera, having to step in frequently to keep them on track. LOL!
The fact that they used TKORs design is amazing. RIP king
i built one of these with a 5 gallon bucket, a 10" cast iron frying pan and a 10" table saw blade. i used a 40amp battery booster and it worked like gangbusters. i built it to clean the frying pan, but it created so many rust bubbles that were flammable as hell when the battery charger leads sparked i almost blew up the garage. so more amps, and just plain ole 12 volts.
this produces, 22 V.(not 22 V of power), and 100 W of power. You run current through the water, not voltage.
Tested is looking more and more like a Mythbuster episode and Mythbuster is looking more like Tested. Not that I'm complaining...
That wasn't 15 liters ,but it was more than 5 bubbles, Adam. Remember that? Good times, good times. LOL!
The large distance between the H and the O plate will severely limit the amount of gas you can produce in that rig. Ideally you want the + and - plates under like 10mm from each other.
It's easy enough to separate the Oxygen out at the end because the H will always occupy the top 2/3 of whatever container you are collecting it in. Just have to be careful with H + O mixed together from this because it's in the perfect mix to explode :)
Don't worry, it's not as if nearby there is fire or electr--oh wait. :)
Was I the only one watching the guy in the corner and being amazed by how little he moved during the time lapse scene?
Voltage refers to electrical "pressure" and is just a function of power. More volts ≠ more power. You want to look at amperage and calculate wattage to make a comparison.
voltage is the amount of electrons and amperage is how fast the electrons move. there is defiantly a power increase between 1 volt and 1000 volts even If the current is the same.
+Ethan Ford No! Amperes are used to express flow rate of electric charge. One amp is approximately 6.2415093×1018 elementary charges (such as electrons) flowing per second. The energy in a wire travels as an electromagnetic wave typically on the order of 50% to 99% of the speed of light; but that doesn't really matter... that's not amps or volts.
+Eric Morrison
P=IV=(I^2)R=(V^2)/R
because of the definitions of power and resistance, it's possible to express almost any system purely as a function of voltage or current.
Josiah Luscher I got them backwards
"let me just add some hydrogen and oxygen to the water (KOH)" lol
Assuming you are supplying 5.29 amps (as the solar cell indicated as the optimal operating current), you would only produce a little over 2 liters an hour. Since amps and liters produced are directly proportional, you would need about 16.6 A to produce the 15 L in 2 hours.

@@sunapumohit8676 What is your calculation?
To the people saying this thing isn't working like the garbage they threw together at home, or that this must be a deliberate failure, just because it isn't working like how you expect, here's why you've misunderstood this video. When you normally run an ideal hydrolysis cell, you get hydrogen at one pole, and oxygen on the other, in the exact molar ratio they occur in water, 2:1. When you collected gas in elementary or high school chemistry off one of these, normally you have the two electrodes or plates in a cup, beaker or bottle, and you collect the gas produced when you turn the thing on with a balloon or bag, like what they tried here. The main difference between your DIY cell or hobby kit is that the gas you've generated, unless you're very careful, is actually the hydrogen and the oxygen mixed together as they bubble and move through the water. People call this HHO or Brown's gas, and it's pretty cool, but by no means magical, and it can be incredibly unsafe. For one, the gas is just premixed hydrogen and oxygen, in the exact ratio to create an ideal combustion reaction. This mixture cannot be extinguished once ignited, but burns so fast it normally combusts as a large fireball or, if contained or pressurized, an explosion.
This test rig here seems to be designed to generate the hydrogen and oxygen on opposite sides of the device, to prevent the mixture of the two gasses and the creation of an obvious safety hazard. While it sounds nice in theory, just generate hydrogen on one side, and oxygen on the other, and separate them to prevent mixing, it actually doesn't work that simply. In hydrolysis, the water is literally split. The two halves (H+-H+ and O-) are attracted to their respective oppositely charged electrode, which means they need to travel through the liquid water to get there. The further they have to travel, however, the harder it is to do this. Instead, it becomes much easier for the water to simply heat up, instead of split, and use up the electrical energy that way, much like how a heated kettle or blanket disperses heat. This doesn't generate much gas at all, and is the chief reason it's kind of hard to generate safe, pure hydrogen at home. The more power you pump in, the easier it is to split the water, sure, but the less efficient the device becomes, as it generates more and more waste heat. This generator was undone by the fact that they really wanted to get pure hydrogen and oxygen on opposite sides, and separated the plates extremely far apart, and forced the ions of Hydrogen and Oxygen to travel much too far. In fact, I'd bet most anything that if they dipped their hands in the water after their trial run, it would've been substantially warmer than they anticipated. There's a pretty interesting video on carsandwater's channel (the guy who does the red hot nickel ball stuff) where he disassembles his HHO generator, and shows the internals. He has a large amount of 'neutral' plates, hooked up to nothing, to conduct the electrical current through the water better, and to prevent the ions from having the massive travel resistances they might otherwise experience. He also adds Potassium Hydroxide, better known as Draino, to the water, to increase the water's electrical conductivity (since water is actually a passable electrical insulator without a dissolved ion content). I dunno if these guys are being paid off by gas companies or something, but the issues they had here, and the issues the Mythbusters had way back when are pretty much due to the fact that it's remarkable hard to electrically rip water into an explosive gas mixture safely, and a difficulty overcoming the challenges of both electrical and ionic conductivity in water. There's a lot of great info out there on this stuff, but a lot of misinformation and plain misunderstanding and paranoia as well. Stay safe friends!
Andrew Bowling holy shit you must have a comfortable keyboard!
Andrew Bowling , I bet your a fun person to be around 😵
Lol
Spot on.
What is more explosive? Browns gas, pure hydrogen, or pure oxygen?
KING OF RANDOM! Saw him upload that video before he blew up. I miss his old experiments...
not sure what you messed up but this does work and sure as hell produces more than that...
Hmm you guys failed yet there are hundreds of videos of people making it work perfectly with just baking soda water and dc power. I am guessing you failed horribly because this video was sponserd by Toyota?
was it?
k bee, the majority of videos out there are on HHO aka browns gas generators and not a "pure" hydrogen gas generator that Adam tasked them to build. What they build is in a way a Hofmann style electrolysis apparatus that was invented ways back in 1866 but their implementation here was one with a very very very poor efficiency.
As for the Toyota advertisement in this video, you do know that the Toyota Mirai that shows up in the ad is a hydrogen fuel cell powered vehicle so failing in their task of generating pure hydrogen isn't advantageous to the sponsor as you appear to make it out to be.
Some rough numbers, theoretically based on 100% Water electrolysis efficiency you would need about 50 Watts of electricity for one hour to generate the 15 liters of Hydrogen gas at NTP. They do not mention how much time they had their electrolysis running but for grins and giggles lets say for one hour (shadow angle didn't change much in the video) @ assumed 50% efficiency of the solar panel (panel was laying flat on the ground and not angled towards the sun) and they got 15 ml (or so they say) of Hydrogen on the end which would make it a 0.1% efficiency for their apparatus. Electrolysis of Water is in general very inefficient but what they got is really horrible.
More numbers for grins and giggles, the Toyota Mirai has an EPA rating of 108 km (67 miles) per kg of Hydrogen (it uses highly compressed Hydrogen but we'll ignore that here). One kg of Hydrogen equals 12000 Liters of Hydrogen gas at NTP so with the 15 liters of Hydrogen that Adam tasked them with it would have just gotten 0.135 km (0.084 miles) and note that Hydrogen fuel cell powered cars like the Mirai are far more efficient than your run of the mill ICE powered car.
Looking at the big picture no matter how you twist and turn it even with a higher efficiency electrolysis apparatus than their contraption it would still require lots of electric power to separate sufficient quantities of Hydrogen to be useful thus not cost effective.
Milan Swoboda Not quite true it doesnt take that much HHO to enhance the combustion. If you had the abilitiy to tune for the mixture of hydrogen oxygen enriched burn you can gain back alot of efficiency in overall output of the engine. Problem is there are no products out there that can accomplish the tuning required consistently. Manufacturers have leaner burn changes locked out of most engines parameters and makes for a very difficult and illusive tuning process.
The ECU of the modern fuel injected ICE engine adjusts the injected fuel amount in accordance to the oxygen content in the exhaust stream, various other parameters like various temperatures, throttle position, ...etc. and the internal fuel map to obtain the best possible Air to fuel ratio / stoichiometric mixture. Now sure the make believe story of the HHO system snakeoil sales is that you add the HHO mixture to it and the added HHO which on itself a stoichiometric mixture, will make a cleaner burn and therefore less gasoline will be needed for the same power. Sounds fully plausible to the poor folks out there which want to believe they can save some money on gasoline with the HHO system pixie dust. Well reality is that the engine uses some of it's power to produce the electricity for the HHO system via the alternator (yes the electricity doesn't just magically appear) and both the car alternator and the HHO system are far below 100% efficient therefore you will ALWAYS use more power than you gain from the HHO generation period! Now sure there are some of those tricksters that may also sell you a different oxygen sensor or an electronic box that will fool the ECU into the engine having a rich mixture thus reducing the fuel but that's a road map to catastrophic engine failure due to the higher temperatures and danger of pre-ignition from the overly lean Air to fuel mixture.
I for once want to see some factual results on these pixy dust HHO systems in Cars. Not these snake oil sales man associates which will state "it worked great on my car" , " I saved xxxx dollars on gas in a month" , ...etc. I want to see true traceable numbers from an EPA or similar certified facility with before and after HHO results on equal testing scenarios.
Until then I will say that if anyone is considering buying one of those make believe HHO systems, reconsider because in the end the only one with more money in the pocket will be the one that sold you the system and the hole in your own pocket will surely be larger than before the purchase.
Milan Swoboda Milan Swoboda Sorry but you are wrong and are overlooking key information. Checkout what Scott over at Central Valley HHO is doing. Also checkout my video on the science of fuel combustion.
I'm really disappointed in the tested crew on this one...You need to play with your electrolyte concentration and boost the amperage...not the voltage...cmon guys.(Adam, I grew up watching you and Jamie, why in the world would you throw in the towel on this..its such a cool experiment.
Hidden agenda ! make things look too easy everyone would do the same TO BE fair he did show the poly bag with a LOT more gas than the balloon so on a guilt trip me thinks !
9:19 Adam goes from good spirits to realizing they failed on purpose. He looks and sounds upset lol. "Pissed but need to stay calm" face scratch and everything lol
Hydrogen fuel prices range from $12.85 to more than $16 per kilogram (kg), but the most common price is $13.99 per kg (equivalent on a price per energy basis to $5.60 per gallon of gasoline), which translates to an operating cost of $0.21 per mile.
Hydrogen industry paid them off so you would not make it at home...
Many things are off here. Most have been stated already. But a solar panel has an open voltage of 22 volts but as soon as you put a load on it, it drops to around 16 volts. Also hydrogen is an extremely small element. It will pass through a plastic bag. At the slow rate of production they likely lost at quickly as the produced.
the electrodes are a light year away from each other
Its correct
I can make more hydrogen in 15 mins then you guys make all day
+Ian not really sure why you would need to separate hho anyway both gasses are combustible.
Exactly. The way I home brewed my hydrogen, it wasn't pure but it had a lot more energy than alternate fuel sources. potentially a lot more dangerous chemicals but hey it was free to make,
Thomas Joseph oxygen isn't combustible. It helps with combustion.
It's weird they had so little success with this.. We had a science teacher build one of these in class once, and it was no where near as complicated of a build.. Plus he had a circuit to up the voltage, dono why these guys didn't do that, 22 volts is pathetic. And when our teacher turned his on, the water was practically boiling!
He filled a whole balloon by the end of the class.. Then, tossing safety to the wind, he took us outside, tied a flammable string to the balloon, and lit it.. A few seconds later, every window in the surrounding block was shattered, and our ears were ringing.. Of course, he got in a ton of trouble for that, but it was the coolest science experiment I ever witnessed in school.. heh
+smlifyrasor Yeah, Tested's rig has a lot of empty space, so there's a lot of stable water just sitting there. They tried to 'maximize' surface area, but didn't do that at all, only about 1/3 of the rig is at work at any time, if that. A little more research would have probably yielded a better result, specially with a shop like that.
+smlifyrasor How big was the balloon?
+smlifyrasor Holy shit, you teacher was awesome.
+smlifyrasor How did your science teacher's gasifier develop enough pressure to inflate a balloon? Just gas bubbling up is not going to overcome the elasticity of a balloon skin.
+Paul Frederick Well, hard to remember because it was over a decade ago.. But it was a very big balloon (maybe a weather balloon?), and I think it had already been pre-stretched or used for something, fully inflated and then deflated.. Plus he didn't really fill it to it's max, because that wasn't necessary, so it was still a bit floppy and wrinkly.. But that didn't matter cause it was still huge..
Also, I don't think this would even be a problem, as long as the system was properly sealed, eventually the pressure would build up anyway? I don't think pressure would stop the electrolysis, and there would be no where for the water to go, so the expanding gas bubbles would still keep filling it up.
Adam, I made one when I was 15 that was 15 feet high and could fill a ballon full of hydrogen in 10 minutes. Lots of salt, 120v dc and I think 40 amps, with a few cups of salt.
Wow , these people really are working with a high school level of understanding.
These people obviously didn't do their homework either
adam wanted 15L, but he never stated at what pressure! XD
Lol
noooope the pressure depends on how much you force into the vessel, regardless of shape/material of vessel. think about your car tyre.. it looks fully inflated at 30 psi, yet you can pump 70, 100, whatever psi into it at risk of it bursting. A tyre filled with air at 100psi will contain a greater volume (litres) of air than one filled at 30psi.
+Crima Joco balloon is it's own material? the more you know.
lol such a nerdy response
Drew Maggio I immediately thought the same thing. Lol
Norm and Will, don't use gloves with rotating tools. It is very dangerous.
gsgsrgsrgrsgrsgrs
+SgtStinger here go play with this ladder
vizionthing WTF are you even on about? Are you trying to say that using the safest method of doing something is unnecessary? Because I'd rather nick or cut my hand a bit while not wearing gloves than potentially loose a finger or three if the glove were to catch on the drill bit.
Was going to say the same thing but I was sure I'd find it in the comments.. And sure enough! I was not the only one to see the danger
Seen a few people loose fingers or hands over the years because of that shit.
I'd rather loose a chunk if flesh than the whole hand - & that's why you don't wear gloves while working rotary tools.
If your separating the two "elements" , later mix them in the perfect effective and efficient way once seperated not by using a timer but a flywheel a large one to compress the gases with force and not ignite the mixture via timing of a spark but using pure compreaaion of the mixture of oxygen and hydrogen "boom"
Positive & negative electrodes should alternate as close to each other as possible, with partitions to channel the separate gasses. Disimiliar metals ( copper-zinc ) creates a better galvanic current. Platinum electrodes have the best catalytic reaction and hold up in the caustic environment.
Most of the diy HHO producers use stainless because of oxidative film forming on electrode surface.
It's funny how you guys still insist on "Jamie & Adam Tested"
click bait
+Thiago Perry jamie does do the occasional thing with them, "shrub pruner drone". but yes it is mostly Adam
+Kyle A not even that... adam is promoting tested as the future of everyhting basically but almost never appears besides the podcast
+Thiago Perry They invested heavily in it.
how NOT to do Hydrogen should be the title .....everything is wrong in this video
The old bait and switch. Wanted to see adam build this.
Just a little correction that I didn''t see anyone mention is that the hydrogen/oxygen production in NOT dependent of the voltage but of the current! The lower the voltage more efficient it is, in theory you only need about 1,481 V to produce hydrogen, anything above that is just heat
Since Adam is the master of building stands and displays for things he was probably looking at that 'stand' going what the fuck is that lol
Why is it that every time these people do something it is to disprove rather than prove something works? They took King of Random's Hydrogen cell and just screwed it up royally. The plates are way too far apart. Plus you can use two or more solar cells to produce more voltage. This was a big disappointment for me.
Steve Rabon They didn't disprove anything lol.
Why did they take King of Random's Hydrogen cell and pretty much do the opposite than what he did?. For somebody as smart as these dudes to screw up a working model isn't being very smart if you ask me. They already did this same thing before so why did they do it again knowing it wasn't going to work? They knew it wasn't going to work is the reason they did it again to post it on here. Laugh at that
I'm glad somebody else noticed they basically copied his entire design and didn't credit him at all.
Jo Schmo If you actually watched the video you'd realize they do credit him at 1:10.
Plus the balloon and bag they were trying to collect the Hydrogen in was too porous....the H atoms just flow right out...that why they didn’t collect much...lol
They’re not as smart as they think they are.
"How difficult it gonna be!? It's the most abundant element in the universe!" well I guess it's to hard for you guys...
King of Random did this at 5 liters per hour. Lmao
Correction bro Its per minute ✌
Yes, more amps is what is needed to do that!
& its 5 liters per minute, not hours, more like 300 liters per hour. lol
He had two car batteries involved... Where these two had one whimpy solar panel. It would take an entire solar panel array to get good results. But them using solar did answer a curiosity I had... It is possible. Just need more than one panel lol
they basically copied his design😂
Trying to disprove a functional experiment -> Trying to replicate the experiment not adhering to the original parameters and totally neglecting how the "improvements" can change the final result for the worse -> Experiment fails -> "It's lame because it does not work"
SEEMS LEGIT
I'm not sure where you are getting that they are trying to replicate Grants experiment. They made a design change, to separate hydrogen from oxygen, in the gas production. Grant wanted a mixed gas, for the violent and entertaining results that can provide, Adam wanted pure Hydrogen.
I have seen a Holden Kingswood run on water without a fuel cell of any kind, he just increased the jets in the carburetor to twice there size to allow enough water to flow and made a high voltage coil to burn it in the motor, because if you place water under a vacuum and hit it with a ex-ray frequency releases hydrogen and is a scientific fact.
WOW! Thats great for cutting a beer can in half. Will it run my car??
Higher voltage doesn't necessarily mean faster production, you have to take into account amperage.
was about to say the same thing, the effective current is more important so likely the only way to do this in any time effective manner is at insane voltages or high amperage. likely in commercial settings this is done in thousands of volts if not higher(to offset the resistance induced by the water) or at really high currents.
+Jay Koerner whoops I'm wrong(in part commercially it's done at 1.43v normally for efficiency reasons normally with heated water at 100°c to minimize loses in energy for both heating and splitting the bonds usual in high pressure systems
Voltage is proportional to current drawn....
its not about the volts, its about the watts, the current.
I was watching this and I'm like, just use a ridiculous transformer and infinite profit. Oh wait, that's not how this works, that's not how any of this works.
+Andre Swarts I was thinking the same thing. Wouldn't the car battery provide tons of more current?
+Andre Swarts but if you increase the voltage at constant resistance you also increase the current
+Andre Swarts *watts, the power ??
+Sam Holliday Well W=VxI so he's not wrong
Hydrogen is a really sneaky gas. From the looks of things, I don't think you had the connection between the balloon and the tubes secure enough
agh hydrolysis is completely different from electrolysis.
Also voltage essentially dictates what reactions CAN happen. If you're using high voltages, you tend to wear out your electrodes very fast. Current affects how fast those reactions happen.
can you say corporate sponsored
Keith Clarke *cough* *cough* *COUGH*
It says it on the screen for a solid 4 seconds at the beginning.
So that's why it doesn't work... Toyota doesn't want it to work (for obvious reasons)
I would guess that you'd get better results with a much smaller separation between the two electrodes. Because you're pushing electrons in one side (to H2), your ions have to take a long time (or be driven by a high voltage = more speed) to the other side to balance the charge. If you put the electrodes much closer, you could generate much more gas.
Hexavalent Chromium is released when using stainless steel in electrolysis. How did you handle the disposal of this highly controlled hazardous material that you unnecessarily released when you could have used iron or steel instead?
This cell is running on very low current and thats the main issue because the volts only matter to overcome the potential of whatever your seperating. you would still need then a few extra volts to beat the resistance of the electrolyte.
Once the resistance of the cell is low enough and you have enough amps to run through the system you are good to go.
HHO cells dont need to worry about stuff like current density too much, but other electrolytic cells may require it to prevent anode destruction.
2:22 the cringe of using a leather glove on a drill press
Don't google "degloving". I warned you.
Here the voltage is not considerable while making HYDROGEN/HHO
AS THE AMPS INCREASES HYDROGEN PRODUCTION INCREASES.100W IS NOT NECESSARY ,BUT YOU CAN GET 15 LPM BY GIVING 30 AMPS IN LESS THAN 5 MINUTES, YOU HAVE WASTED A LOT OF TIME AND YOU GOT 15ML LOL.
Veekshith Balabhakthula you can get 15 liters per minute by giving 30 amps in less than 5 minutes?
I needed a good laugh. How is a single 100 watt solar panel ever going to produce more hydrogen than a 500 cold cranking amp battery!? Lol!!!
I learned a lot in his video.I could never even dream that the fumes produced by water are far more dangerous than the fumes produced by potassium hydroxide. Thank you,i don't believe i could hear that anywhere else :)))
Great video, well done! You could increase the efficiency dramatically by placing the electrodes closer to each other, because then the electrical resistance between them would be much less. That would result in a much higher current allowing more gas to be created at the electrodes.
6 years and me and 3 other guys gave a fuch
pro tip- use a T connector in the middle and a 3'rd tube to allow refuel without stopping the aparatus
That IS an excellent idea, except they need an entirely different rig to have it work worth a crap. I thought the same thing when they were assembling this turd. +1
As soon as I saw the Toyota sponsorship at the beginning I knew that this video was set to fail. It appears as if the failure was intentional, possibly to discourage anyone on attempting this for themselves. Keeping everyone reliant on the petroleum industry.
Volkswagen now in 2022 has the market on hydrogen in Europe you will never see any advances in the usa the oil industry has a lot invested in electric battery technology at this time which will never take off either .
Such a giant gap between the anode and cathode... What conductivity you increased using large surface area nodes was undone by having them spread out around a foot apart. Put them much closer together, and to keep gasses separated, do not use a U joint tube, use a sharp V shape.
"22 volts of power and about 100 watts of energy"
/fail physics
+Patrik Pålsson Why? It's just over 4 amps.
David Lowery Well volt is voltage not power, Watts is power and energy in these cases is usually the product of power and time.
Energy is measured in Joules.
+elephystry or kilowatt, Watt, calorie, horsepower, or even barrel of oil.. I could go on.
Grant Thompson - "The King of Random" had already done it and you guys just improvised on it, I appreciate the fact that you mentioned him cheers for chivalry.what would happen if you perforated the steel plates-Thanks
If you put holes in the plates you would get whats called voltage creep, electricity jumping across the holes instead of through the water making it less efficient.
Anon with the size of the gap between the plates in this one i dont think creep would matter. They are litterally in seperate containers, im suprised they got any hho out of this one at all.
Steve Edley but it’s not separate containers....all one container....the shape forces the gases to separate instead of mix.
I'm so glad everyone here understand how science works right??
not every time you try something will it work, but you learned form your experience which is science.
The King of Random's Grant Tommpson died recently. May he rest in peace.
Norm and Will are fun to watch, they try to get along but always fail. Well it seems that indeed opposites attract someway or another.
remember follow the money. mythbusters's major contributor is BIG OIL corporations.
just drop aluminum in NaOH water solution.
should work as well with your KOH electrolyte.
okay but how are you getting hydrogen one side and oxygen on the other? Surely whether the molecule splits on the anode or the cathode, hydrogen and oxygen are are being released in the same place as the atom is split?
We didn't have this particular experiment in hughschool science.
