This is true, but when you have a fire in the missile compartment of a submarine containing 16 missiles, each hosting xx nuclear warheads, you do want it extinguished.... immediately. The idea of a sprinkler system was a non starter.. so. That lot aside, you are never more than ten paces away from an Emergency Breathing System mask anyway. We did use halon at one time (in the diesel generator room) until someone pointed out that the halon will kill the watchkeeper quicker than either A. the fire or B. Nitrogen.

As far as expansion goes, I believe that they would both expand at the same rate for a given temperature rise. That said, the heat capacity of the two gases may differ enough (not likely since air is 78% nitrogen) to be measurable. That is to say that one gas *may* absorb more heat without showing the same temperature rise. Again, I doubt it.

Hmm I still can't get there, but, I suppose the air even bone dry, will still have the greater propensity to absorb water vapour. That however, will make insignificant changes...

I'm thinking as you mentioned earlier, with Nitrogen, tyre trial runs will be consistent, despite temperature, weather, ambient storage conditions for the gas.

Whereas with air.. more dedicated storage conditions are required.

End of it all, it won't make a witches tit's worth of difference to the average motorist.

Yeah,,,,, what he said.

Michael Moore: Nitrogen was invented by the white male majority dictators that we 'voted in' years ago. It does not even exist, and it is the reason that my family and friends can't find a job.

Ralph Nader: Will it get me votes? If so, I'm in.

The UK has NUCLEAR WEAPONS? How can that be? The UK can't even run a national health system, how can they maintain a nuclear arsenal?

I'm worried. Very worried.

Very Successfully, over fourty years incident free. I think we are the only nuclear nation with that boast!

But then again they are all trained on France so if there is an accidental launch... no big deal!

OK, so which one of you "Frenchmen" voted YES in the poll ??

Most of the shops that push nitrogen inflation, don't buy nitrogen. They buy nitrogen generators. These work by forcing compressed air through a "special membrane" which allows O2, moisture, etc. to pass, but captures the N2O. You then fill and vacuum the tire repeatedly until you have the correct nitrogen concentration. My question is this: when you first fill a new tire, you have to check the pressure frequently, but over time it stabilizes, only needing minor corrections. Doesn't this seem to indicate that the tire itself is acting as a "nitrogen generator" by slowly bleeding "contaminants" away? I know for a fact that a clean, dry air supply gives much more stable tire pressures than the typical gas station pump.

the u.s. has been incident free for 40 years, but lost a couple of subs (thresher and scorpion) just prior to.

still better than the russians.

How did this thread go from demagnetizing tires to lost subs?

I had posted a link to a page on 3 Mile Island, but my retard alarm went off just as I hit the "Post" key. 3 Mile Island didn't involve warheads, but rather knuckleheads.

I did my best to find out about the virtues of demagnetizing tires. Curiously enough when I searched for "demagnetizing tires" on Google, this thread came up first. I no longer trust Google to give me sites that are even remotely credible .

Anyway, as I scrolled past the link to this dribble, I found a couple of patents that suggest that tires might be magnetized in the manufacturing process. This patent suggests that magnetizing the tire would allow detection of the orientation or direction of the tire throughout manufacturing. This other patent deals with impregnating the tire with magnetic particles without reducing the life/strength of the tire. It mentions that the relevance for their invention is in tires that are used with a "Sidewall Torsional Sensor System" that "modern vehicles are often equipped with" (which is news to me).

So, using this tire demagnetization service will actually make your "Sidewall Torsional Sensor System" not work, and then, you will have to come back for more service . I think "tire demagnetization" is listed right next to "OEM nail add-ons" in the tire shop's price list.

Nope, haven't had one of them neither.

Yes, but we won't mention the Shettland Island that was contaminated with Antrax for the past 25 years, will we ...

....and furthermore, we won't discuss why and how it became contaminated will we.. If ya wanna throw %%%%, get some info behind it first.

how much iron is there in rubber? I forget...

Well, none in the rubber, but loads in the steel belted tyrewall

[Ext1jdh]

but a mass of rotating iron (steel belt) will produce a magnetic field.

It's a fact. I saw it in a movie once

Testing of biological weapons during WWII, to check the feasibility of infecting German cities ... at least that's what WikiPedia says.

Yep, that IS what wikipedia says, however, as has been proven before, wiki is only as well informed as it's contributors, unfortunately, I'm obliged to leave it at that.
