Fluffers and gas milage



Fluffers and gas milage

A ceramic  fluffer glued to my jeep surface

It is often surprising for folks to discover just how dense and sticky the air around really is.  While we, at our normal speed of movement (approaching 3 mph) don’t notice the surrounding air, just stand in a pickup bed going 80 miles an hour, or observe the nozzle end of a vacuum cleaner and you will quickly realize that “at speed” air has an unusual ability to grab, hold on to, and pull along near by objects.   If air really was as harmless as we usually imagine then tornados and hurricanes would not be a human problem. 

When air slides over a car’s surface it grabs the surfaces and holds the car back.  If we can break this suction somehow, we can reduce air resistance and increase gas mileage.  Car designs and surface treatments, such as car wax, might help reduce surface cohesion, but often, these methods, because they stress flowing lines along smooth surfaces, really don’t help much.

Small fluffer mold for making fluffers

The only solution to breaking the suction of air to the car surface, at speed, is to fluff up the air along the surface somehow, just enough to allow the car to slip through the air with the least disruption of the stable air possible.  To accomplish this successfully, air must be “fluffed” up at the car surface in some uniform way. In other words, we want to move just the air necessary to travel through it and not push gobs of air aside as this represents “work” and results in loss of gas mileage.

 After studying this problem for some time my friend (nameless of course) and I have discovered a way to efficiently fluff air at the car surface.  We do this the way a shark cuts the resistance to water; by “frothing” the air successfully at the surface.  After much thought we designed the fluffers shown in this post.

The next problem was constructing enough fluffers to test this scientific Fcat  (my computer for some reason won’t allow me to type the word “fact”?? not sure why).  This post is mostly about how to construct your own fluffers from ceramic material, much like the ceramic tiles that coat space rockets.  But to move on.

formed green clay fluffers to be dried and  fired

Here is the ideal fluffer shape.  To accomplish this I made molds of thick clay slabs.  These forms of mine are fired in a ceramic kiln at 1835 degrees f, the standard bisque clay temperature, utilized through out the world and clay classrooms. 

Any clay student can then hand press clay into the forms or pour clay slip and allow it to dry.  In either case, the dry bisque form will “release” the puppy fluffer (in it‘s “puppy” state) for firing, again at bisque temperatures. 

A single fluffer glued to a car, not much effect!

Next the fired fluffers must be glued to the car in an organized manner.  We have solved this problem with silicone glue.  Works great.  The fluffers must be glued in an organized pattern all over your car in such a way as to distribute the fluffing evenly.  I estimate that it will take about 40-60 fluffers per car.

Now for the final glue on.  Find a willing friend and glue the fluffers in place.  You should have no problem as this will almost certainly result in improved gas mileage, even for a Geo metro or other small car that has difficulty reaching 100 mph. 

and, a closer shot

DISCLAIMER:  as of today, in-spite of the great idea presented in this post, I still haven’t found a friend who will let me glue fluffers on their car.  Well, I’ll do a follow up post just as soon as that happens.  

I hope you like this post, it took almost 6 months of “R & D’ to develop this remarkable idea.  We think it would work most effectively on race cars, gopher vacums, and hand held tornados.  Any ideas you might have to further the “fluffer” are appreciated, and professional “fluffers” are ask to not join in on this electronic interchange.

Anyone can observe that if a tree, like this Garry oak In Tieton Canyon, had to sustain wind forces based on it's square foot cross section, they would fall down at the first gust.  However, the individual leaves break up the moving air (fluff it) and reduce the drag of the wind through the willows.  Without leaves, a tree would topple over almost as fast a leaves without a tree, or as we always say, "if there are more trees in a forest than leaves on any tree, than there will be at least two trees with the same number of leaves".  Not sure what that proves???  Oh well, stay tuned for an actual magazine review in a week or so, you'll like it!!!

  1. I'm still waiting for an entire car covered in fluffers. Have you contacted the mythbusters yet?
