    To push air through gasoline like that is a fire hazard, that maybe a reason they stick to liquid instead of vapor, at least until the gas hits the carburetor. The results are not surprising, it is just safer to use the conventional system rather than creating vapor like that. There is a reason why fuel tanks are sealed, to prevent to much oxygen to get in.

    Can you do a video comparison to show which is better overall for powering up a home furnace in winter & perhaps 2 appliances, I'm interested in longevity vs. noise / fuel consumed? A fuel-less generator or one that's run on fuel?

    That was a cool cool experiment! wouldn't have believed it if I hadn't seen it :)

    I experimented with this one summer back in the 80's after hearing about the "POGUE" carburetor in the local paper. I got my car to run off vapors for a few miles, but lost power, the more I drove it. Eventually it quit running, and had to switch back to liquid gasoline to get back home. I later found out I was siphoning off the lighter ends of the gas (mostly Heptane) which vaporizes at about 55 degrees. Once those were gone, the system was done. My set up was similar to his in many ways, except I heated the fuel with exhaust gases. The lawn mower in this video here is not really pulling vapors off, but misting the fuel and as others have said, just making a simple carburetor out of it. In short, he's not really running the mower off of vapors, just a gasoline mist. And of course, the mileage wont be much, if any, better.

    During the year of the first space shuttle explosion, Hot Rod magazine had an article on a mechanic in Florida (I think it was Smokey Yunick) that had altered a Ford 4 cylinder car to where it produced over 250hp and got 50mpg. According to the article, the mechanic blocked of 50% of the radiator, and used the engine heat to heat the fuel/air mixture to a certain temperature that maximized the energy output of the gasoline, which temp the article did not reveal, but was available in "any high school physics book." He did induce enough airflow to prevent an explosive backfire, but otherwise it was normally aspirated. According to the mechanic, the optimum fuel/air mixture temp would vary according to altitude, but with modern electronics, it would be simple to sense O2 percentage and adjust for that. Any thoughts?

    Well liquid doesn't burn anyway, it's the gas phase hovering above it.

    Exon actually in the 70's and achieved 400 mpg verified by the Guinness Book of World Records on a Ford Opal. The apparatus was different. It was a tray with a large surface area. Had a thin layer of gas across the tray with a wicking material over it. Steel wool it thought. This I assume was more fume than mist. This may produce more efficient results. And the car companies are not interested in efficient vehicles. Government around the world won't allow what is one off the biggest drivers in the economy to have it's profits to be virtually cut in half in months. Many good carburetors have come out over decades that prove this. Will share one if you're interested.

    Jezzuz if you Yanks stopped calling petrol, gas you might be more aware of "gas" engines running on propane, butane, methane, hydrogen - THOSE are gas(es) so petrol vapour which is a gas running a car engine should not come as a surprise at all!Oh yeah! One other thing, car starter spray is usually Ether - ANOTHER gas! Sheesh!

    I find this video very fascinating. It solidifies what I learned in physics, liquids don't burn.

    Carbs are supposed to atomise fuel, rather than turn it into a vapour, in the 70's when i was a kid, you could buy inlet gaskets with fine metal gauze covering the ports. This gave genuine increases in fuel economy, between 12-12%. I have seen better results than this video, where AV-gas is used, combined with dehumidifier filters used to 'wick' the fuel, rather than air-vaccum bubbling it. I imagine fuel-temp would also be a factor in economy, anythings worth a go, especially when fuel should be dirt-cheap , according to current oil-prices. Dave, NZ

    Do you think you could make an engine run on that sap saturated pine wood called "fat wood" or "rich pine"? I have always thought that if you used exhaust heat to heat that wood in a closed chamber you could use the vapor to run an engine and switch over to vapor only. What do you think?

    I do see where this can possibly could be as an advantage. If you have contaminated fuel or dirt in your fuel or water in your fuel something like that that's all going to stay in the tank and not evaporate separate possibly water but even then it's going to be mixing with the gas Vapors

    Good day I'm from Ont. Mennonite had 5 hp engine sitting there with no carb, but a water tap threaded on, asked what it was. He took some ginger-ale, pour some in a pail, I guess gas was in pail, pull cord after 3-4 pulls it started. He controlled speed with tap. Thanks

    Carburetors and me don't mix so I have run numerous engines, generators, boats and a truck off of vapors over the years until I could get the engines fixed. Some for a long time. I have yet to get any noticeable fuel savings. I'd say the carburetor does a pretty good job, but maybe adding some hydrogen would do the job. I know that works. I have done it and got about a 45% fuel savings.

    I think we use liquid fuel instead of vapor because Liquid is more compact and condensed than vapor, and easier to store, the fuel injector/carburetor pretty much tries to vaporize fuel anyway, so I think you gained an extra minute by kinda skipping the carb/FuelInjector, I could be wrong though. I'm just theorizing from what i know...

    While everyone’s saying you made a carburetor basically, your invention still lasted longer on fuel in comparison to just pouring fuel in the the tank and letting the carburetor on the lawnmower do it’s work. Basically a massive carb upgrade

    "Gas vapors" and "liquid gas"... Who decided that a gas is a liquid to begin with?

    Regular carburetors actually deliver a vapor for combustion.. so is there another side or unknown factor that should be considered?

    I actually thought it would work, after all engines will run on LP or propane. Nice job!

    I saw a video using Xtreme Green engine treatment. After using the treatment, they drained the oil and ran the motor with no oil and the engine ran perfect with no issues no matter how long they ran the engine! The company stated they will replace your engine if after using their product and the engine fails due to lack of lubrications. Is it true the engine will run once treated with Xtreme Green?

    I had to use a push mower growing up. And a walk mower when I mowed for a golf course. If It came back down to me walk mowing my yard again I would kill the grass with round up.

    Try using hydrogen gas instead of gas vapors. (Extracting the hydrogen yourself with electrolysis would be awesome!) I plan to try getting a lawnmower running on hydrogen that I extract myself this summer.

  • Andy P

    I think I suggested this, some people are making Hydrogen; with electricity; from water to run their cars using electricity or course, BUT, I also know Hydrogen can be split out from water; another way; using the metal Gallium, AND the Gallium can be reused, just an FYI though it Gallium breaks-down Aluminum and some other metals, and can be very destructive if splatted around your nice garage so be careful when you try this, you are going to try it aren't you? please please.....I'd like to see it done, then patented, then $plit 50 50 with me, LOL, take care, . .. ... .. .. .. . ;-)p.s. High-efficiency, triple-junction gallium arsenide solar cells cover the sides of U.S. Naval Academy satellite MidSTAR-1, so it must be good stuff!?

    What's funny is how silly this video is. Love your vids. But gasoline ONLY burns in vapor form. It will not burn in liquid form. This is the basic principle in carburetors. Also modern tech efi is agonizing the fuel so much that it vaporizes by the time spark ignition occurs. Furthermore top fuel car commonly blow up engine from no ignition and the gas hydro locking the engine. A single non spark event is enough to blow up the engine due to how much fuel they are spraying at wot.

    stoichiometric ratio has to be achieved one way or the other. The benefit here is probably better vaporization, which is where the small percentage comes in. But, I doubt that carburetor is dialed in perfectly. Fuel injected engines get damn close to perfect stoichiometry anyway.

    I don't know what people think the carb does? It vaporizes the gas. That's why I like throttle body injection better than port injection. Of course, i prefer a carb to any fuel injection.

    That milkyness is atmospheric moisture from the air.

    Not entirely sure why you went to so much trouble. I just took the air filter out of the circuit, stuck a 1 inch hose into the top of the fuel tank (without it touching the fuel) and stuck the other end of that into the (existing) air intake on the carby. Worked like a charm.
