Very interesting. Sounds too good to be true. The Pogue carburetor was invented in the early 1930's, but today it seems it is only investigated by tinkers. I could only find hearsay on 100-200 mpg road tests. No supposed test was well documented.
One of the comments on Hasslberger's blog may explain why car companies aren't interested.
"Modern computer injection systems go exactly in the opposite direction, by injecting all droplets with almost no atomization. Because the volume of fuel vapor occupies 600 times the volume of liquid fuel, pre-vaporization of the fuel removes space for air intake, and reduces engine power (which is sometimes confusing, because it could lead to increased miles/gal, but at lower power level)."
Car companies and many consumers are interested in power. Vaporization makes the combustion fast and hot which leads to high efficiency, but low power. You can get more gas (and therefore power) into the combustion chamber if the gas is injected in the more compressed liquid form (drops) than in the vapor form.
X Prize Foundation, to "inspire a new generation of super-efficient vehicles," held a contest with a 10-million-dollar prize that was divided between the winners of three competitions. Use of vapor carburettors was not used by any of the winners. That seems to indicate that pre-vaporization is not all what it is said to be.
