It's pretty well known that fools who heard of Mr. Pogue from Canada buy into this type of engineering quackery!
FACT: There is absolutely NO incentive or valid business reason why ANY automotive manufacturer would NOT want their products to get good or great fuel mileage.
Do you think that GM, FORD, DCX or others would sit by as their businesses crash from HIGH fuel costs? These firms are loosing BILLIONS of dollars each year.
If such an invention existed they would be the first to go after it as it could well mean their survival.
If the "Big Oil" firms had bought this device to keep it off the market they would have been dragged into the courts years ago by every firm that uses fuel.
Nice try - but it never happened.
I think you should do a little reasearch on Mr. Pogues invention as well as others that have greatly improved gas mpg's before you post a reply. I have and it is a fact. I'm sure the car makers have made a decision that to let the high mileage inventions out of the bag will hurt their profits alot more than any poor sales that are usually temporary. They are also financially intertwined with the oil companies and of course if everyone got 100-200 mpg's that means alot less gas tax revenues. I think you are a bit naive about this subject. I'm not saying that the car and oil companies are evil...they are just protecting their profits but it is very short sighted of them. By the way, when I was 20, I copied some plans for a simpler vapor system using the radiator water for my big plymouth fury and went from 13 to 28 mpg's. The gas is formulated different now and takes a higher temp to vaporize or you would be seeing alot of simple hot water vapor systems on the market.
