After reading this story my mind was blown. I'm not a mechanic, but Bill Cain is. He's been rebuilding cars since he was a teenager. Recently he built an engine for a 1970 Plymouth Fury that recycled unused gasoline from the engine and converted its waste into power. This turns a 20 mpg engine into a 100 mpg engine. Let me state that he built this in the repair shop he owns. The story itself is actually very well written and gives us a taste of Bill Cain the man and his innovation. While not totally new, the idea seems to be working and there are experts who think it's viable. This is the kind of thinking we need while harder to develop alternatives are still in the planning stages. My only hesitation is, if a self-taught mechanic in St. Louis can do it how come none of the automakers have thought of it yet?

      Note that the "100mpg" figure is "in theory", and that no actual measurement of mileage has been performed. Also note that the article claims normal engines have about 20% efficiency (most of the loss being heat), and yet he's claiming to get 5 times as much per gallon. That looks a lot like a claim to 100% efficiency. In the Engineering world, to which I have only slight access, "100% efficiency" is a Giant Alarm Bell that someone is a crank or simply mad. (Notwithstanding the fact that using heated gasoline vapour reduce waste heat to zero. I'd doubt, in fact, that it could really reduce waste heat at all, though in theory it might gain some efficiency simply by providing more complete combustion.) I'm also absolutely dubious of "secret" methods for doing such things. If he's for-real, he should have already patented the principle and mechanism, and thus be able to share it without worry about being ripped off. (If, for example, Ford stole the idea from him, I'm sure GM would be happy to bankroll the lawsuit to stop them, wouldn't they?) The "100mpg carburetor" myth may never die, but it Just Ain't Possible. (A 100mpg engine, maybe. But an old, inefficient monster like that getting 100mpg from a change in carburetion? Literally impossible. The carburetor simply isn't the source of the inefficiencies, like waste heat. All it can address, at best, is incomplete combustion.)

      "After reading this story, my mind was blown." Doubtless so, but then again it was apparently blown prior to reading the story as well. Sucking off gasoline is notorious as a pre-cursor to that condition.

      have thoughts? mechanics? I think maybe this got by a lazy editor who didn't check out the facts.

      Well first of all, its not impossible. Mainly because, along time ago I thought about it a lot and did some research, and decided to make a chamber for a 1976 ford maverick. I used an 8 gallon empty propane tank with two check valves from the fuel tank and one into the carb. (Incase something went wrong). I used a separate reservoir to control a small amount of fuel into the tank, (almost like the bobber effect on a toilet.) I used the bobber to keep the fuel low in the tank, and an injector and coil out of a 91 Miata to inject fuel. Then i used a separate line on the top of the tank to pull the vapor into the carb. In order to get the fuel to vaporize you need heat, so I used a combination of three things (oil heat, coolant heat, and exhaust heat). Each being in separate pipes coiled around the tank to heat it. (Excess heat waist from the engine). I also used a modified diverter valve that injects fuel into the carb. until it gets up to operating temperature, then it uses the fuel vapor to run on. When the temperature gets two low, it senses with a custom temp switch that it needs to inject fuel momentarily. With this process I went from getting an average of 20 mpg to about 70-90 mpg. Give or take the temperature of the weather.

      I have developed a vapor chamber which atomizes liquid gas then separates mist from vapor leaving pure vapor while recovering condensed liquid gasoline back to the tank to recycle thru the vaporizer cycle 8 high pressure foggers fill the chamber pushing mist across the 200 degree heat elements to assist in vaporization down stream there are 3 chambers atomizer, mist and vapor. I have constructed my matrl from 304 stainless left over from projects at the cape. All machine work is compliments of the company. this enclosed system produces 40 psi pure vapor which will be introduced in a vapor carb ! 1 gal of liquid gasoline = 1600 gal of vapor HOW DO YOU LIKE ME NOW p.s. biily the kidd im takn it bto a whole new level VAPORPIPER

      If you think things like this are impossable, you should do a search for www.113 to 138 mpg.com . From what I know of engines, this is very likely to really work. Check it out.

      Hello, this device is actually probably a copy of Thomas Ogle's design patented in 1978. It actually used the vacuum produced by a standard V-8 motor to draw the vapor fumes produced from boiling the gasoline into the engine. Prior to entering the engine, the fumes passed through several charcoal and neoprene filters and finally into what Thomas Ogle referred to as the black box, which sit inplace of the carberator on the intake manifold. Thomas was actually offered $25 million for this design in 1977 by the oil agencies; however, he turned it down in effort to market his idea. Unfortunetly he died from an apparent drug overdose later. His patent was approved in 1978 and can be downloaded from the united states patent office. When he tested his design he installed it on a 1972 Ford thunderbird with a 429 cubic inch motor and was able to get approximately 100mpg+ on this design.

      nothing is impossible, but 100% efficiency from a self-taught mechanic is. The Jesus wall clock is what scares me. "he should have already patented the principle and mechanism" by Sigivald This is a self-taught mechanic with only a seventh-grade education, you can't hold it against him. he is trying to improve fuel efficiency, unlike some automakers. only time will tell if this turns into a myth or best practice.

      Over 100mpg is possible and has been acheived by the following manufacturers: Toyota ES3, Audi A2TDI, VW Lupo 3L and the 113mpg GM/Fiat. Why don't you skeptics type these names into a search engine and then tell the manufacturers they are liers. Vauxhall and Peugot also achieved 100mpg back in 1976 with their 4 door compacts. If you get 100mpg you are not running at 100% efficiency as the theorectical max for ICE is 420mpg. The efficiency figure of 20% is calculated for a vehicle traveling at 80kmh/50mph speeds above or below this optimum will result in efficiencies as low as 2 %

      the idea is not new the us army used it in the Africa corps in world war 2 if you wonder why the big auto maker dont use it ,, mabey you should ask why all cars are fuel injected today... it is so this technology can not be adapted to newer cars. this is the real oil company conspiracy. write to your senators and demand research in this feild today!

        i SINCERELY FEEL MY VAPORIZER CAN RETRO-FIT A NEW FUEL INJ SYSTEM iM COUNTING on the newer cars computer to mix my vapor thru the injectors

      See you guys need to understand that it is in fact possible. Lets focus on money for a moment. Who is making all the money. THE OIL COMPANIES!!!! Think about it. If we all had cars that went 70 mpg or more the oil companies would loose more money than they could dream of. Did you guys no that Ford was going to realease a certain Carb engine that would handle 70 mpg. But the oil companies payed them off not to do it.

        5 YRS AGO FORD MADE A FOCUS IN GERNANY 75 MPG MITUBI./ TURBO/ DISEL YA CANT BUY THEM HERE WHY THE F NOT IT COULD HAVE BEEN LONGER THAN 5 YEARS AGO THEY WOULDNT SELL ONE TO ME THERE NOT ALOWED IN THIS COUNTRY
