Okay...so I'm a loser-nerd for pointing this out, but I went on a trip to the Oregon coast this week and the forest smelled so good I had my friend steer the car while I undid my seatbelt and poked my head out the sunroof. I was up there for maybe 20 seconds with my eyes just above the wind deflector when I noticed that I could not breath AT ALL. I mean literally. I tried to breathe in through my nose several times and there was nothing to breathe in...like a vacuum. I told my friend about it was he was "Whatever moron!" until I convinced him to try it. Same thing with him. It was kind of eerie. It got our hearts pounding pretty good. If we raised our heads up or down a few inches we could breathe just fine, but there was that certain point between the top of the car and the top of the deflector.

Okay...freaky story, I know...but I had to share!!

I guess that means they designed the wind deflector pretty well. You don't want air back there (especially turbulent air which would increase drag) -- you want to flow smoothly over the top of the deflector and then gently back onto the roofline of your car. Of course, if you opened your window, that would kill the effect.

Man, I never thought studying fluid mechanics would've amounted to anything...heh.

 

I've experienced that too. Makes you wonder how people can ride motorcycles??????

 

That makes sense. If you're ever in the car on the interstate and you go through a brief thunderstorm, pull back the cover and look up...a bunch of water will pool right under the deflector...and stay there even after it has stopped raining.

 

If my sunroof actually worked I would try this. I just realized today that my sunroof will not slide back at all, just pop up. It worked when I first got it. Oh well, I remember reading many threads about this before so I guess its time to start searchin'!

 

Dude...that sucks!! Why don't you just take it to the dealer and have them fix it while it's still under warranty? Then you can deprive yourself of oxygen like I did!!

Tony

 

 

Yeah I probably will take it to the dealer before the warranty runs out. That was only the second time I've even messed with the sunroof since I've had it so its not really bothering me too bad. Just makes me lose even more respect for Nissan's workmanship.

 

Cool, I got to try this!

 

lol!

 

 

If you disconnect the battery for any reason, it will do this. The owner's manual will show you how to reprogram it & get it working again. hopefully this is the problem & it will save you a trip to the dealer.... worth a shot.

Yeah....what he said.

You must manually use the tilt button to reset the slide mechanism....or something like that.

It happened to me too.....

 

If you'll pay attention to my username, you might guess that I have some experience with oxygen intake at high speeds.

What you encountered was osmosis. You were absorbing O2 through your skin (and especially through the wet surface of your eyes) at a very high rate due to the speed of travel through the air.

Since you had all of the O2 you needed, your breathing reflex would not trigger.

Skydivers don't have to breathe at all until after we open our parachutes.

 

Thanks. Yeah the battery has been disconnected several times due to alarm and stereo installs.

 

Now I have heard it all!!

Even frogs cannot absorb enough O2 through their very moist and unobstructed (by clothing, etc.) skin, especially during physical exertion. Even diving nude with special eye moisturing (remember high air flow actually dries things out) will not provide enough O2 to your body...AND...the capillaries of your blood vessels are not designed nor sufficiently close to the skin surface to absorb the O2, no matter how much is present.


You may want to read the:

"HOW DO YOU BREATH IN FREEFALL?

There was some silly nonsense recently that you absorbed oxygen through your skin. This simpily is not true. The skilled skydiver who may appear to be not breathing is actuality doing "ram circular" or continous breathing. Proper positioning of the
mouth and nose will cause an almost laminar-flow air wash through a sufficent portion of your lungs. This is actually quite comfortable."

I got some Enron stock for you.... great deal, only $20/share!!!!

 

Osmosis???!!!???... Perhaps a quick lesson in anatomy.

The human body was not designed to obtain oxygen through the skin, the eyes, or any other part of the body except the lungs in sufficient levels to sustain life on their own. The skin functions as the barrier between the horrors of the external world and the intricacies of our bodies. It is a filter of sorts...allowing certain gas and liquids to permeate to the cells beneath. Some of what gets through is oxygen. Some of what escapes are waste materials.

However, the primary factor here is where the oxygen comes from, and how it is stored in the body. Normal blood carries in it a compound called hemoglobin. This compound is the primary oxygen carrier. When blood passes through the pulmonary system, it flows through the highly oxygenated parts of the lungs called the bronchi. Here it interacts with the air and the hemoglobin attracts the oxygen. The waste material (aka the carbon dioxide) is expelled from the blood back into the lungs and then exhaled.

Nowhere is there any provision for oxygenation via the eyes or skin. I suppose a nice simple test would be to take our skydiver, duct tape his nose and mouth closed and drop him out of a plane to see how well he breathes.

 

with all that 'experience' it is amazing he isn't at the bottom of some (literally) man-made crater!!

 

jjs, jonnyb, you can spit that hook out now ;-)

Shall I tell you why skydivers go up when we open our parachutes?

Or would you rather hear about hitting the pointy end of rain drops?

 

oh, and I was hoping for a story about how the skydiver doesn't really fall...the earth actually comes up to meet him!!

 

Well, now that you mention it ...

I suppose, since gravity is really the attraction of two objects ... no, I'm not going there.

But, I had a very, very smart person believing that it hurts to fall through rain drops because we are hitting the pointy end of the drops (after I made him realize that we DO fall faster than rain drops ... sheesh. and he was a physics major in college, too.)

And, to be precise, jjs and jonnyb did not take the hook. A real catch would have been someone that chimed in with "oh, yeah, I remember that now"

And finally (won't he ever stop) the 'ram-circular' explanation is just as bogus (but you can be sure that I'm going to use it.)

 

Pointy ends of raindrops....HAHAHAHAHAHA

Oh man...the earth really IS flat!

 

Yeah...I don't breath at all when I ride my motorcycle. It lets me concentrate on more important things like not running into falling skydivers as they plummet to earth because they've forgotten to breathe!!
