That thumbnail is a work of art! Hahah!

I always love when a company makes a claim and Todd gets that liitle smirk and says, 'we're gonna test that!'

That video was literally worth $200.00. Thanks to you Todd, that money is still in my pocket.

This reminds me of when I was 16 and bought my first car in the 60's. I bought every gimmick known to man from the JC Whitney catalog. Each installation would boost HP by 15-10%. By all accounts I should have had a 500 HP 283 Chevy, but alas nothing ever changed. I can still hear my dad LHAO. It seems that the products now days are higher tech labelled, but work about as well as I remember. Thanks for doing this, it brought back some great memories. 🤭

My friends and I used to make these in college, we had a Civic that we actually got up to 60 mph with. Everything was stock, except for the homemade HHO generator, BUT we did have to tune the ECU. We did learn that it makes a bigger difference with gasoline engines versus diesel engines. But we did get my 2004 diesel excursion up to 24 MPG. I swear by HHO, but you definitely have to tune the ecu to inject less fuel because the air is richer.

Before watching: It seems like one of those too good to be true things. After watching: it is too good to be true.

Can we all just take a moment and appreciate the time and effort this man and his team puts into these extensive tests. And this one in particular I'd say. Lots of hours in the making..

I appreciate your hard work. I trust no words on a box unless you’ve tested it

Made my own hho unit years ago. Did get noticeable improvements in mileage. Difference…I installed a simple potentiometer on the dash wired into my map sensor. I was telling the computer that there was less air flow than was actually present, thereby causing the engine to call for less fuel. I adjusted based on need and could turn it way down on the interstate allowing for incredible fuel savings.

He drilled holes in his air boxes to test this for us, that's dedication!

The only youtuber that hasn't sold his soul to marketing. edit: Thanks Patrick

As always reliable consistent content! One of the few youtubers who truly accomplishes that!!!

This is the way testing should be done. Thank you for this and all of the other great videos!

I just love his straight to the point with no 10min background story before he starts. Thank you

one of the best you tubers to date, no bs, straight up content, science, and no money farming from companies. MAD respect

I love your videos. When testing, you try to think of any aspect that could change the outcome. Very thorough testing. Great job!

Amazed how you keep your composure Todd. I would have ended the video by walkiung that thing over to a trash can and tossing it in.

This man has wasted countless hours for our enjoyment. I will watch every single video. Always amazing.

I love the symbolism behind giving the closing responses in front of an empty table.

I've seen homemade versions of these in videos claiming great results and have considered making one more than a few times. Guess I'll save myself the trouble... Great info as always. Thanks!

My man i appreciate everything u do on this channel thank you

One of the last few gems of quality content on KZfaq nowadays

"Hey Wilma, who's that nut that's been drag racing past our property a dozen times in a row?" Wilma: That's that lawnmower guy testing snake oil.

Wanted to say thank you for all the information on product performance, you are amazing brother, learning so much about stuff I've always wanted to know.

Parabéns pelo vídeo! A honestidade e a transparências dos seus vídeos deveriam ser modelos para todos os outros canais.

This is the only channel where I finish the whole video before heading to the comments.

Since you drilled that hole in your air intake, I can’t help but suspect a “Which aftermarket cold air intake is best” video in the works lol

Love the attention to detail that you do on your videos.

As always, amazed at how you even come up with the tests you do.

Project Farm: "We obey the laws of thermodynamics in this house, mister!"

This man is amazing. He cut a hole in his air intake for his vehicle, and generator, Much love to you Project Farm!!

Love the video Im a big fan. The biggest variable here is the fuel injected controller that is adding the fuel. The controller cannot see that there is another fuel (hydrogen) being added to the combustion chamber so it keeps running it's normal fuel trim. This means that selling these kits to people is just useless because they are not actually leaning out the gasoline mixture to make room for the HHO to work. If you tune the fuel injector controller (pcm) you can get some small gains in the V8 with the HHO. If you tune the generator or switch to a carb and lean out the gasoline and add HHO, you can get very good gains and maybe almost run 100% on HHO.

Thank you for your effort and testing. You are very thorough and precise. Thanks again for the demo

The 300+ people that disliked the video bought this contraption.

Speaking as a trained chemist, my brain hurts every time I hear "HHO" like it's some kind of mythic mantra. Well done on the debunking!

Thanks for the thorough research sir. It’s appreciated

Like everyone else here, I'm stunned with how much work and effort went into this experiment. Thank you.

This pops up every time gas gets expensive, you'll see it on Craigslist and other selling apps.

Really learn a lot from this channel Easy, simple and well explaining

I love your test on everything, very thorough.

The level of tact in this video cannot be overstated.

I watch all the ads for ProjectFarm. One of the best KZfaqrs put there

I support you! thank you for your work. it is very interesting.

This is actually the best informative video I've seen. You're wasting NO time at all explaining the stuff your talking about, and you're not leaving out any important details. Great work man, you've earned yourself a subscription.

3:05 "I'll go ahead and remove the plastic shavings from the intake so we don't try running the engine on plastic as well." EPIC!

I appreciate you doing this testing because there's a lot of people posting videos to tiktok and Facebook about these and how they get amazing fuel mileage but anybody with any amount of technical background knows it's not going to do anything.

Love Your Channel! God Bless You Bro!

I give props to you for somehow managing to maintain composure throughout this video.

Some say big name manufactures consult him first before making a product and that he once taught a giraffe to curtsy. All we know is, he's Project Farm.

Well done video! I tried this some years ago on a 61 pickup..zero gain in mpg

You use the scientific method so well on all your videos. I love it, thanks.

Would love to see electric pressure washers put to the test! This is the only channel that I will give a like before the intro is even over. Awesome work 👏

PF constantly reinforces the old lesson your mom taught you. If it sounds too good to be true, it probably is.

THANK YOU SO MUCH FOR MAKING THIS VIDEO AND DOING ALL THIS FOR US MUCH APPRECIATED

Very innovative way to test the effectivness of 'HHO" - it indeed clarifies lots of doubts and misunderstandings, thank you for a detailed vid

I have been binge watching you for 3 days, and I am extremely impressed with your engineering skills, dedication, and attention to detail in your videos. To me, your reviews are as good as Consumer Reports reviews in the old days. I am really glad I found you.

This channel has quickly turned into one of my favorites, great content no BS and great editing

Problem is AF mixture is set from the mas and the o2, these systems worked on old Beetles because we would manually adjust the carb to lean out the AF, simple procedure HHO off set carb lean till it sputters, turn on HHO to remove sputter, gently rich the mix until it runs smoothly and you get your MPG increase. Yes oil Temps were checked as was timing to prevent detonation issues. Modern engines see a cleaner burn as leaning out, so the ECU enriches the mix to offset and you get poor MPGs. These systems work better on Diesel as its a static rate of diesel going in versus a variable rate like modern gas engines. Good test but it was missing this variable.

You're simply the best! You are making a big difference in this world. Thank you sir.

i remember a friend of mine around 2006 was trying to convince me that these kits would make our cars get better MPG. Snake oil never dies.

Project Farm's thumbnail game has truly ascended to new heights

Never tried one of these, but my hats off to you for trying. Kind of expected it to be a scam. My cousins and I did a homemade electolysis-gasoline hybrid some 20 years ago. The results were kinda neat with ours. We doubled fuel economy, but only during the first 20 minutes of driving. After that economy tanked big, but still remained slightly above normal. As far as we could deduce, it was something to do with the computer module, and we didn't have the ability to really toy with that. Ended up converting a few family members engines, until there was a little bit of an accident, then we all switched back lol

Thank you for all this testing you are doing . Hope you can continue . If you have not done so would love to see testing of various plug-in Performance Tuning mileage increasing modules for modern vehicles. From personal experience using HHO generator results were a net loss of MPG due to the drag on the engine to produce electricity to power the HHO gas production.

Dude - I'm really impressed. I've seen enough of your videos to know that you're plenty smart enough to know that you're testing a scam but you went ahead and gave it a more than fair test with no opinion at all even though I'm sure you had one. An excellent review. Good job!

It may not have cleaned the plugs, but it sure did clean out your wallet.

Appreciate you making content like this.

thanks for this review , was wondering about that for past 5 yrs but was waiting for jusy this review

You’re the man for making all of these non-sponsored videos for us to see how products really perform! Keep up the good work boss 👍

I remember before everyone had the availability of the internet at anytime, a lot of people automatically believed anything they heard on TV or in magazines. Thanks to your channel and a few others we now see the real results of these products.

Great test. Very nicely carried out!

I dig the research you do. Way to call out the BS garbage products! Thanks man!

I feel like his BS meter is so finely tuned that you can tell the outcome just by the way he says "we're gonna test that.."

Bro I love the tests u do keep it up bud

I can really appreciate Project Farm's dedication toward controlled testing, going the extra step by not allowing companies to muddy the waters by sending him free products.

Another GREAT comparison and SO well done and explained all the way through. Thank you for your time and expense in trying these new ideas that make sense but do nothing.

You are the person I trust for the truth of all the things on the market. I greatly appreciate your honesty, hard work, time and channel sir👍.

Great job as usual. You are the new Myth Buster. I didn't even know these existed. I will keep it that way now. Thanks!

I’m 76. Can’t remember how many ‘new inventions’ were advertised in my life time to improve your car’s performance. None of them worked. They were usually seen in Popular Mechanics, Mechanics Illustrated and Popular Science. Small ads in the back of the magazine.

Excellent 👌 been wondering about these

Great video and effort on testing the HHO generator! However, it looks like there might have been a crucial component missing in your setup - a fuel regulator. The main idea behind HHO systems is to supplement the traditional fuel, allowing your engine to operate on the lowest possible amount of it. A fuel regulator can help control the flow and ensure that the engine uses minimal gasoline or diesel, while benefiting from the higher octane level provided by the hydrogen. This adjustment could significantly improve your system's efficiency. Would love to see how this change impacts your results in future tests!

The entire skateboard, inline skate, scooter, roller derby, and longboard community is patiently waiting for a test on the longest rolling and most durable bearings.

Just wanted to thank you again for doing the HVAC filter video, I upgraded to a merv 14 filter and I swear I haven't sneezed at home since

Pensé en comprar un kit de estos, pero gracias a tu vídeo he cambiado de idea, gracias por el contenido.

This Man is fantastic. I really appreciate his work!

If you don't already have them, you need to make a t-shirt that says: Project Farm "We're gonna test that!" :D

Snake oil. Unfortunately a lot of people still fall for this :(

There are some issues you weren't aware of. The electrolyte works optimally at 165F. Ideally you want 'ported' vacuum to draw in the brown's gas. Drilled hole in the intake is not ported vacuum. Most cars no longer have ported vacuum. If you have a PVC valve and connect to that, the benefits are reversed (you want more of the gas when you accelerate not less and PVC vacuum is reverse of that). You want no more than 20 amp load. About 10amp is optimal so as not to place drag on the alternator. You want a brown's gas output of 1 liter per minute per liter of engine size. Additionally there are other things to trick the engine into utilizing the brown's gas effectively (deals with the upstream O2 sensor and IAT). Just slapping one on can improve things a bit up to about 20% increase in MPG without other modifications. I got double on the wife's car, but for a day. Her 4 cyl ran like a 6 cyl as far as power and acceleration went. Seems the computer didn't like the car getting that great of MPG and brought the mapping back into what the manufacturer's specs were. I even installed 3 lights too. Green meaning it is on and working. Yellow meant it was low on water. Red means pull yer arse over and see what the problem is (usually blown fuse or loose wire or something but could be worse). Car would work with any of the lights on. Had to keep resetting the computer every time I used the system. Finally removed it due to the hassle. The hydrogen in that will slowly remove built up carbon. When there is no free carbon available (takes a LONG time) it will pull carbon out of any steel parts (this is called Hydrogen embrittlement). Those plates are made from stainless steel. Best plates are made from Platinum. Plate spacing is roughly 1.1mm for great results. One hot plate and at least 5 or more neutral plates before the negative plate. Some use electronics to pulse the DC current to to cell around 44kHz. The water you must use has to be store bought distilled water. Other water has contaminants in it that reduce efficiency, eat plates, draw too much current, create too much heat, and create sludge in the system. Never use salt in a system like that. It creates Hydrogen chloride gas which can be explosive in sunlight. With the dry cell, you don't have to worry about hitting bumps and drawing the electrolyte into the engine like you do with a wet cell. Remember, there is no free ride with anything. It takes more energy to break the water molecules than you get out of it. But the advantage is more efficient combustion and resulting more power and better MPG if you keep your foot out of it. Just a few tidbits for everyone. Author - redo the test but drive the car for 1 hour SANELY in warm weather so the system gets to operating temperature. Then test it again. We saw you run that stop sign! lol

Thanks for your time investment on this test! Good job!

You're one of the few youtubers i really appreciate. No bs, straight to the chase, superb content. I feel warm and fuzzy on this side of youtube bc it reminds me of how youtube felt a long time ago! Thanks for being so unbiased and transparent as to throughly showcase exactly how you evaluate these gizmos, so that if in doubt we can go ahead and test for ourselves. You seem like the kinda fella I'd chug a cold one with. Rock on!

thanks, Todd another great money saver and time and trouble. I am still amazed where you get all the testing tools.....awesome.

Next time make sure you place a pyramid on the device and cleanse away the bad MPGs with healing crystals

Thanks for this detailed , very well explained expirment.

thanks for making this. well done

"I'm going to install the HHO with zip ties cause as soon as this test is over I'm taking this crap off".

I knew what the results would be, but I still watched and appreciate the work. Thanks Todd!

Have made my own using a mason jar. It did increase mileage a lot . Chevy 350ci V-8 went from 15 mpg to a bit over 50mpg.. The Chevy 4cyl went from 40 mpg to over 100mpg.

I learn a great deal watching your show. Thank you so much.

Looks like it's about as effective as Uncle Rico's time machine, but without the physical pain.

A better way of saving fuel is to fit small wheels at the front and big wheels at the back, then you are always driving downhill except for steep mountain roads.

Thanks for your channel !!
