Could This Little Gadget Clean Up Our Car & Truck Engines?

Leef2_Info_lrgAside from purchasing a new vehicle with cleaner emissions and higher efficiency, how can one reduce the amount of harmful tailpipe emissions? If this crowdfunding campaign succeeds, you may be able to add this little machine to an existing car or truck engine, which is claimed to reduce particulate matter emissions, increase combustion efficiency, and produce breathable oxygen, without reducing the performance of the vehicle.

The LeefH2 takes aim at the emissions of the dirty internal combustion engine, especially diesels, which account for large amounts of harmful particulate matter in the air, by functioning as a kind of mechanical leaf in order to feed the engine with very small amounts of hydrogen. By adding minute amounts of hydrogen to the combustion chamber, the existing fuel is said to burn faster and more completely, reducing fuel consumption and increasing efficiency.

According to the LeefH2 Indiegogo campaign page, the device can be integrated into any combustion engine, without any major changes to the vehicle, and can reduce particulate matter emissions by almost 50%, while also producing oxygen (from splitting water into hydrogen and oxygen).

The LeefH2 doesn’t store any hydrogen, but rather produces it in small amounts on demand, and the hydrogen isn’t the main fuel for the vehicle, which continues to burn gas or diesel as originally designed.

“The LeefH2TM (Leveraging Energy Efficient Fuel with Hydrogen) promotes combustion efficiency and reduces particulate matter emissions in all types of hydrocarbon-based fuels by adding hydrogen to the air used for combustion. Hydrogen increases the laminar flame speed of virtually all hydrocarbon fuels, causing far more fuel to be burned during the combustion process, thereby lowering the amount of unburned fuel exiting the exhaust. Less unburned fuels equals less particulate matter emissions. Increasing combustion efficiency also reduces fuel consumption and lowers green house gases.” – HNO Green Fuels

According to HNO, a single tree can produce up to 260 pounds of oxygen each year, and the LeefH2 could produce (on average), about 365 pounds of oxygen each year, so if the claims prove out, this device can essentially use a fossil-fueled vehicle into a virtual tree that produces breathable oxygen while operating.

  • These scams have been around for years- and that’s all these hydrogen “generators” are.

    Simply put, adding hydrogen to a fuel doesn’t improve its combustion efficiency. If anything, it takes up one of the free electrons in a fuel’s carbon chain that would, under normal circumstances, allow an oxygen molecule (O2) to bond with it. That bonding of O2 to the fuel molecule *IS* combustion.

    Further, almost all the “science” that backs these claims is politely referred to as “fringe science”, even by Wikipedia (http://en.wikipedia.org/wiki/Oxyhydrogen, the molecule left over when you remove a hydrogen atom from H2O). In real life, where we don’t have to be polite, it’s known as “bullshit”.

    Do something better with your money than give it to this snake oil-selling douchebag using the word “science” and your lack of knowledge of fuels and organic chemistry to make a quick buck. Buy some chicken nuggets. Give it to a homeless guy. Burn it. The choice is yours – but, seriously, f*** this guy with a cactus.

      Well just because you don’t believe in gravity doesn’t mean that it doesn’t exist. All you have to do is jump off a tall (or short) building to prove it.

      Hydrogen DOES increase the Laminar flame speed of hydrocarbon based fuels. It has been proven in experiments dating back to the 70’s. Thus improving combustion efficiency.

      Also, I would not necessarily consider Wikipedia a “scientific” source for information…..maybe Princeton or MIT might be better sources?

      First of all, just to prove some of the flame speed characteristics of hydrogen, take a look at this Non-HNO Green Fuels video. This is not a conspiracy. We did not have this gentleman make this video just to “scam” you.

      https://www.youtube.com/watch?v=65KIexy4New

      If you want to know what true “Scientist” and “Researchers” have done in this field, do a google search for hydrogen and Laminar Flame Speed.

      Meanwhile, let me give you a couple more NON-HNO Green Fuels reports on Laminar Flame Speed. Which is the reason our product does what it does.

      Please note, each of these documents have lot and lots of scientific references……beyond the likes of Wikipedia…not that I don’t appreciate Wikipedia sometimes…but not for this.

      So is it a “Scam”, only if we in the future were somehow able to get all of these researchers to write these papers in the past, just to try to “fool” a few people that know how to cut and past what they have heard other people say.

      • Laminar flame speed/flam-front travel does NOT equal thermal efficiency. It’s cool, though, because even if it did, it wouldn’t matter. These devices have been around since well before the 1970s, didn’t solve the fuel crisis then, or in 2008, and haven’t – most crucially – received CARB certification. That means that installing one of these on your truck, in addition to turning into a “tree” (LOL!), will net you a hefty fine. From $1000-10,000 per DAY if you’re a commercial trucker operating in Cali, because this is tampering with the certified fuel and emissions systems.

    • JackieB

      Laminar Flame Speed has been proven time and time again. Looks like we got another WikiScientist lulz

      • Memes do not make you right, and selecting which bits of data to use don’t make you look smart, either.

        SO, let’s assume this works. How much water would you need to get enough hydrogen into the air/fuel mix to get this to work? Assuming you get enough to make a difference on a conventional car (you won’t), how do you adjust the ignition timing to compensate for the higher flame speed? What device is optimizing the air fuel mix to maintain stoichiometric volume? That would would be about 15:1 with gasoline … what would be with a mix that’s 1% hydrogen? How about 10%? Since different amounts of fuel and hydrogen will be present under varying conditions, how would you continually adjust for stoich, compression, and ignition timing?

        What’s that? You have no idea *and* that little plastic box up there can’t possibly do any of those things?

        Exactly.

  • While I’m at it, tampering with or modifying your car’s fuel and emissions systems is illegal, and can be punished by state and federal fines of up to $10,000, with the vehicle being impounded (specific punishments vary by state). In addition, you *will* void your vehicle’s warranty by adding this BS hydrogen-enhancer nonsense, it will *not* work, and you will be required to spend a butt-ton of money to repair your car’s O2 sensors, catalytic converters, and (unless your lucky) the engine itself, since no part of your fuel system or drivetrain was designed to operate with the highly reactive hydrogen and oxyhydrogen gasses that this system will not produce in sufficient quantities to “enhance” combustion (ProTip: higher flame-front speeds do not always = more efficient combustion or greater thermal efficiencies) but will produce them in enough quantity to eat away at the nikasil linings common in many of today’s engine block cylinders.

    • DonSaidThis

      Apples and Oranges. Apples and Oranges.

      No Oxyhydrogen here. No Oxyhydrogen gasses. Only a very small amount of H2….just enough to speed up the combustion. Hydrogen IS NOT THE FUEL. The percentage to fuel is “EXTREMELY” small….I won’t post the percentage here but its smaller that most people can imagine. Hydrogen is just a catalyst. To do what hydrogen does….Increase the Laminar Flame Speed (you probably never heard of that term maybe?). Just because you have never heard of Laminar Flame Speed doesn’t mean it doesn’t exist.

      No one is “tampering” with the emissions system, no reason to.

      The O2 from the LeefH2 does NOT go into the combustion chamber, it is released to the atmosphere….This is NOT HHO. There is no oxyhydrogen gas produced. There is no extra O2 to be detected by the O2 sensors, because there is no extra O2, only H2….which has a proven (scientifically proven) track record of increasing the Laminar Flame Speed of hydrocarbon based fuels.

      Furthermore, our focus is NOT gasoline engines. Even though gasoline engines produce very fine particulates also, our focus is on DIESEL ENGINES and diesel engine Particulate Matter. We aren’t just making claims of particulate matter reductions, we have tested in EPA approved labs, doing EPA approved testing protocols.

      I can’t make you believe our testing results, but like gravity, that doesn’t mean it doesn’t exist.

      Don Owens – Inventor LeefH2

      • Fair enough, Don. Please see my answers to Ricky, which use H2 math, as opposed to HHO and HO.

  • Paula

    This is great. I hope they can get this on everything. They need to put them on those freight trains. They’re so bad for the environment with the PM2.5. I live right by a railroad and it’s terrible. If it reduces that and produces oxygen, sign me up.

    • It’s a scam. I hope they all go to prison.

  • Rick

    Rick to Jo Borras

    I am amazed at all the non scientist saying what they think. It’s almost like someone gave them some talking points. Facts doesn’t matter. Your lack of faith that someone may, just may have actually, truly found the real answer to a problem everyone knows the world has. Amazing. We would still be driving a horse and buggy if we listened to the guys that said a horse could out run a locomotive..

    • You assume to much, Ricky. I’ve been working with racing engines and custom-built fuel systems for decades. That’s cool though, your PRESENCE of faith and DESIRE TO BELIEVE in this *OBVIOUS* scam won’t be swayed by mere mathematics.

      Here’s a fun experiment for you, though, just to be cute.

      Let’s assume that’s a liter of water in there. Let’s also assume that 100% of the hydrogen in it is “released” by that electric current in just 1 minute. (Hint: it ain’t, but let’s give you the benefit of the doubt).

      Now, let’s assume you’re using this on a 2 liter engine (small, even by today’s standards). With every revolution, then, that engine is moving 1 liter of air (assuming it’s a 4-stroker).

      At 3000 rpm at highway speeds (about right for must 2 liter engines) that means we’re moving 1500 liters of air, which means that- even using my insane “1 liter of water converted 100%” number up there, that would mean that you’d only get ~500 ml of hydrogen (not even that) … which, you’ll notice, is about one third of 1% of the total air entering the engine (in the video, you’ll see that the supposed hydrogen “released” from the water is being fed to the engine on the intake side).

      One third of one percent of the air, which itself interacts with fuel in a 15:1 ratio of volume, is not enough, plain and simple, to produce the massive results he’s claiming- especially when you consider that the limiting reagent in this chemical reaction isn’t the air *or* the fuel, but, rather, the oxygen density of the air being sucked up during the engine’s intake cycle … BUT EVEN IF IT WAS, you’d be out of air in sixty seconds.

      What will you do for a 30 minute trip, Ricky? Pack 30 minutes of 100% pure water? How much electric current would be needed, you think, to fry up that much water in just 60 seconds? How is that current produced in a car? By magic?

      NO! it’s produced by the fuel burning and turning a mechanical generator (the alternator!). Adding electrical devices increases load, and will require the use of more fuel to compensate … which, darn. You’ll need even more than those 30 liters to make up for that, won’t you?

      BAM.

      Science.

      Stop spending your money on stupid ideas that have no hope of working, please, and stop wasting your credibility by supporting scammers who prey on people’s ignorance of automotive systems/desire to believe/hope for salvation.

    Hello again, Jo Borras.

    You saying we’re a “scam” cannot, and will not, stop us from reducing particulate matter and producing breathable oxygen with diesel engines. We have a mission to help improve world-wide human and environmental health and doing so has been proven in EPA-approved labs.

    It’s a shame because a large chunk of the green tech industry runs into this same nonsense– people who don’t fully understand the science and technology behind their products and who’d rather spend time writing negative comments on blogs, websites, and twitter, than help those who know how to change the game and make a difference.

    As stated before, we cannot make you believe our test results. We’re not going to bother because it’s a waste of our time and we have a business to run. To be frank, we wouldn’t normally respond to this sort of comment because we see through this. But we’re doing so because we were asked, and we want to be transparent and give answers to anyone else who doesn’t know any better and could be so unfortunate to believe you.

    We have to wonder, did you watch the video? Have you visited our website? You were already greatly mistaken when you mentioned oxyhydrogen, or HHO. Had you watched the video, you would’ve seen at 0:33, we say “we separate water into it’s TWO chemical components: hydrogen and oxygen.”

    Hydrogen (H2) and Oxygen (O2). We never mentioned anything else, and surely not oxyhydrogen.

    To repeat, we do not separate water into oxyhydrogen. In order to make a criticism about a product, we politely ask you to first watch and listen to the video. Had you done that, you probably wouldn’t have written your comments in the first place. But that’s ok–what’s done is done.

    You said, “These devices have been around since well before the 1970s…”

    The LeefH2 has not been around since the 1970’s.

    Again, you are referring to devices that use alkaline electrolysis to chemically separate water into oxyhydrogen, or HHO. Oxyhydrogen is a completely different chemical composition.

    We use Proton Exchange Membrane electrolysis to separate water into hydrogen, and separately, oxygen.

    The entire mathematical scenario you wrote to commenter Rick is not scientifically sound or accurate. We have to be straight with you and agree with commenter Jackie B: Pairing words such as “ratio” and “rpm” with numbers unfortunately does not make you an engineer, scientist, or mathematician.

    We’re sorry, but it takes hard work, dedication, and years of experience.

    Did you read the studies from MIT and Princeton we referenced in our response to your previous comment? You still seem to be unaware of the fundamentals of hydrogen and its effects when introduced into the combustion chamber.

    If you read the studies from MIT and Princeton, you would have understood only a small amount of hydrogen is necessary to see increased combustion efficiency. No one needs, in your words, “massive amounts” to see increased efficiency. We highly recommend taking the time to learn about the process of Laminar Flame Speed from reputable sources, not rely on Wikipedia.

    Increased combustion efficiency in diesel engines with the LeefH2 leads to a 50% reduction in particulate matter. And because we use a process of PEM electrolysis, that oxygen does not go into the combustion chamber–which means the oxygen will be emitted into the atmosphere. This has been tested, and there’s nothing we can do to make you believe that.

    Jo Borras, we sincerely do appreciate your passion displayed when talking about new green technology, but please do your research before you try to discredit our work.

    Thank You,
    HNO Green Fuels

    • I watched your video(s). They’re garbage. So is your site. Very well produced garbage, of course, full of shoddy claims, bad math (if you can even call it “math”), and peppered with the word “science” and seasoned with an extra helping of fear monger and messianic promises, as if saying “science” makes the actual science irrelevant.

      That said, you can ABSOLUTELY make me, and everyone else believe your test results thanks to this awesome thing called scientific rigor. See, that means that you can publish your lab results, along with your methods, and make your hardware available for independent testing and verification. You could also try 1) refuting my math, or 2) getting the EPA/CARB to endorse your results and verify your claims.

      My guess? None of that will happen, just like generating a few paltry ml of hydrogen can’t produce the results you claim … which, I suspect, you already know.

      Here’s hoping this is the last I, or anyone else, ever hears from you or your bogus product.

      • DonSaidThis

        Joe,

        I really have no idea why someone would be so quickly willing to trash someone’s work and discoveries so vehemently. Calling my videos garbage. Garbage? Give me a break. What exactly are you disputing? That Hydrogen does not increase combustion efficiency? That our test results in EPA approved labs are not true? That I would take the time to just make all of this up? That I would set up a facility and hire people to do research and design work, just so I could “scam” a few people like you?

        I agree, some of the claims made in the HHO world over the years have been outrageous. In my testing over the years, I could never figure out why my test results were no where near some of the claims that were being made by the people promoting “car electrolysis” (as I have heard people refer to electrolysis). But I was also testing in an environment that most wouldn’t spend the time or money to test in. It cost money to test in EPA approved labs. Relatively “big” money. But we tested because we needed to know the truth. What the results in EPA approved labs would show, not just test results we did in our own environment.

        And all of the test we did were not stellar. We had to tweak and regroup and tweak and regroup. We just didn’t show up at the lab one day and have a 50% reduction in particulate matter after one test. And as we tweaked and regrouped and tweaked and regrouped, our thoughts were certainly not “let’s keep this up so that we can scam this guy named Joe one day in the future”.

        All I know is this, when we started I thought like every other thinking human being would think (like you currently think) that “the more hydrogen the better”. The very first series of test proved that to be wrong…..because there ARE limits on the amount of hydrogen you can produce by the alternator and still have a gain, especially when it comes to fuel economy with gasoline engines. There are limits on the load that you can put on the alternator. And most “Hydrogen Generators” exceed those limits. But as we continued our testing, we found out a lot of things about hydrogen, more things that I care to mention in this reply.

        Bottom line, we discovered what we discovered. That there is a significant reduction in particulate matter in diesel engines if the “proper” amount of hydrogen is used. And that “proper” amount is less than most would think.

        And we have made applications with CARB, but if you know anything about that process, it also does not occur overnight.

        So go ahead, take the time to look at the youtube video on the flame speed of hydrogen versus other other fuels. Take the time to read the research done at Princeton and MIT and others on how the Laminar Flame Speed of virtually all hydrocarbon based fuels is increased with a small amounts of hydrogen addition.

        If you do, you will know what we know, that hydrogen does do what hydrogen does….which is speed up the combustion and increases combustion efficiency. If you don’t, you will always be in the dark spewing hate and nonsense.

        • Michael

          Not only that, but they have their white papers on their website. He probably didn’t even look at that.

    Oh I wish I’d found this article 2 months ago. I was busy arguing with their bogus science on Twitter, and even did a big scientific write up about it, similar to your response to Ricky. Check it http://pastebin.com/Rr6vMRvp
    Just waiting now for these guys to get arrested, because clearly Indiegogo won’t do anything about it.
