Interesting idea
 

Here's an interesting idea. Anybody else run across anything like this.

That's the biggest load of **** I've heard lately.

Maybe that's the secret to the 60 mpg Hummer. Actually i was wondering if anyone had run across a place that specializes in High FE vehicles before.:)

I agree.

I personally put pixie dust in my gas tank... just a little though.. My car becomes lighter and my FE skyrockets.

Honestly, if people followed those ten they would save fuel...so let them wax!

Any surface irregularities that a wax job would cover up are buried in the air boundary layer. If you don't believe it, try sprinkling some fine grain sand (Florida beach sand) on the top of your car and drive down the road at 65mph. Those sand grains will still be there when reach the end of your trip (unless you run through some rain).

I dunno, i think it makes sense. I dunno what an air boundary layer is, but it seems to me it would have less friction for the reason basjoos said of the sprinkling of sand on your car, but I suppose pixie dust in the gas tank might be an easier way to improve FE than waxing on a regular basis.

Where can I find some of this stuff?

Gary -

At the Candy Baron of course :p !

But, I don't know the ratio of pixie dust to gasoline to use.

The air boundary layer is the thin layer of air right next to the surface that is stationary relative to the surface. As you move further from the surface you encounter air that is in motion. Typical boundary layers are less than 1mm thick.

To put a picture to what basjoos said ;)

At the point of contact, there's a "zero slip" condition. A tiny bit above that point - there's a tiny bit of air movement.

And easy way to feel this is to open your window and put your hand against the side of your door (while moving at faster speeds). You shouldn't feel too much in the way of wind.

In any case - nature knows perfectly smooth objects are not efficient at moving through fluids... Think shark skin and look at the bumps on whale fins :thumbup: Then look at dimpled golf balls, fuzzy tennis balls, and how frequently baseballs are changed in game.
