Something about air... I forget.

^^^That'd be the one!

Sorry, I got myself distracted with garbage night and then working on a project for my car.

Thanks. No frostbite!

It was not that hot. I wished that I had my insulated bag, I would have made it home with more of that unobtanium that we call ice.

Some of my decisions make more sense than others...

wouldnt a hot car be more aerodynamic? due to the less viscous air near the surface

[Xist]

It stands to reason, but I do not know how much of a difference it would make, like this:

That sounds like a blown flap concept.
They fell out of favor in the 60's due the huge power requirement for the compressed air.

I looked through the first hundred Google results for "plane truck compressed air Popular Science" and, of course, it was a waste of my time.

I was just thinking though, if a low-pressure zone, like the bottom of your windshield, increases drag, and so does a high-pressure zone that pretend Ecomodders have on their side mirrors, would there be any gain by piping air from the top of the hood to around the mirrors. How much of the wake could you fill?

These are the things on my mind when I try studying for finals...

See if you can track down J.J.Cornish III.He was the chief aerodynamicist for Lockheed Aircraft and published a related paper with the American Institute of Aeronautics and Astronautics (AIAA).
Alex Tremulis wrote of him in the 1980s,believing that by now,all cars would be using this technology.
I have only one example of an aircraft with STOL capability,built in Japan,which uses an entire jet turbine engine to provide the necessary air volume for the wings to function.

Sounds like the "augmentor wing" that NASA flew in the 80s. (70s?)

how about spraying a less viscous gas onto the surface , like ? only be good for a short run however, On the boats they vent air under the boat for a pretty big difference in drag at moderate speed, i think volvo patented it maybe 15 years ago , used on quite a few high performance boats now I think formula yachts uses it, in the james bond move, the world is not enough there is a sport cruiser driven in a chase scene in teh very beginning, we have the identical boat at the marina where i work and it has huge slots midship to carry air under the hull, heard it makes around 15 % improvement. course not really applicable but interesting.

One of the most innovative STOL designs ever conceived.

The Russians reportedly have a supercavitating torpedo, named the Shkval. It apparently uses the combination of a specially shaped nose section, and a rocket engine, to achieve speeds of 200+ knots underwater. The nose section supports a bubble that envelopes the entire torpedo, which significantly reduces drag.
