Dallas Cowboys Stadium Seating and Atmospheric CO2

Posted on 01/27/2014 11:31:06 AM PST by rktman

With the possibility of the coldest Super Bowl ever coming this week, this story about CO2 concentration seemed appropriate.

Ryan Scott Welch writes:

Anthony as you know, many people don’t know much about the earth’s atmosphere. For example, when questioned about how much CO2 is in our atmosphere most people give me a guess of somewhere between 30% and 70%. When I tell them that CO2 is only 0.04% or really about 395 ppm (parts per million) they generally look at me as if I was speaking some kind of foreign language. The layman simply cannot convert 0.04% of the atmosphere or 395 ppm into anything they can picture or relate to. In searching for some way to help the layman to understand the earth’s atmosphere, CO2, and the human contribution to atmospheric CO2, I came upon the idea of relating a sample of the atmosphere to something that nearly every person has seen, a football stadium.

I suppose they could have used any stadium. LOL! Reminds me of my last airplane flight. When booking there was a box to check if you wanted to "contribute" to their "green" initiative to help pay for some of the CO2 emitted during the flight. Strangely, I didn't see a box to check that asked if I would like the plane to use more fuel and thus "spew" more CO2 emissions during the flight to help save the plant life on earth. I woulda checked that one. I didn't check the "saviors box" either.

Kinda like the nitrogen filled tire scam.

Helium yes. Nitrogen no. Helium makes your tires last longer since the basically float above the pavement. No. Really. LOL!

Make it easier on them; express it as four tenths of one percent. Otherwise they'll take away anything from four percent to forty percent when they hear zero point zero four!

human caused CO2 is less than 1/2 of a seat out of 100,000 seats (molecules).

Nitrogen fill is used in race car tires because it’s “dry” and the pressure rise with temperature is more linear.

Lib response. “BS. We all KNOW it’s 40%. The scientist known as algore told us so and we even bought some carbon credits from him to help counter the cursed CO2.”

I fill my own tires up with 70% nitrogen gas!

How do you empty the tires completely before adding nitrogen?

You would need a tire machine and air compressor in a room filled only with nitrogen and the workers would have to be in spacesuits...

Makes me wanna run a scan where “Fill your tires with Argon because argon is inert and won’t decay your tires”...

They also use it on airplanes and other high performance machines.

Not sure how the average streetcar needs anything about the 78% concentration we are accustomed to using.

I did notice some of the posters on WUWT were taking the article to task but to me it’s a simple way to show how “much” we contribute as opposed to natural means. Of course if you dig deeper and toss in a bunch of algoreitisms you can show it’s much more complicated but is simply a way to show some that we aren’t much of a problem. “Save the plants. Drive your truck!”

So does hydroplaning on bald tires... lol

We used nitrogen in our race car tires.

Heat build up in the tire caused less expansion in the gas in the tire. Equals less messing with chassis and suspension set up.

LOL. I worked at a tire shop many years ago (high school). We had a couple of race teams that we mounted tires for. They never wanted us to put air in the tires, just set the beads so they could fill them themselves with nitrogen (pure nitrogen). When I asked how they did that, since air was 78% nitrogen already, they seemed surprised. They did say they sucked all the air out and re-filled with nitrogen several times to get it pure.

Every once in a while we would have a customer ask us to fill their new tires with nitrogen. We had one guy that would say, "We can put 78% nitrogen in them for free. Will that do?"

I also include 0.04% CO2 so that there’s not as much in the atmosphere, thus reducing my carbon footprint.

That would be four hundredths of one percent. Yeah, math is hard... Just tell them "almost nothing" next time.

If it is 80% nitrogen and 20% oxygen, where are all the other gasses?

How do you set the beads with pure nitrogen? I assume you have to "suck" all the oxygenated air out of the tire before you put pure nitrogen back in. Obviously this would unseat the tire beads.

I know they do it. But how? Curious.

The point is that pure nitrogen is “dry” - no water content - compared to plain old air. It’s the water content that drives pressure changes disproportionally with temperature changes - if the air compressor has a dryer it’s just as good.

I understand that point. I also understand the scam for passenger vehicles at tire shops. But for the race teams that do it (if they still do), how do they go about it?

Set tire on rim, bleed some nitrogen into tire and use nitrogen to pop the tire and then fill with nitrogen. By the time the bead is set, some air has already been displaced by nitrogen. What air is left, is at atmospheric pressure, by the time usable tire pressure is achieved, the percentage of air to nitrogen is very small.

Dry air is made up of 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide.

By using compressed nitrogen, you're raising the nitrogen content to 98-99%. Also, air chemistry is affected by humidity.

Scuba tank air is also dry, so you could probably get the same basic results from filling your tires with compressed air from a scuba tank as you do from filling with compressed pure nitrogen.

CO2 was the POLITICAL PICK. The environmental leftists could never make it the warming catalyst for obvious reasons. That’s why they have had to MANIPULATE and CHERRY PICK the data, then lie like hell to advance their agenda. Next time you see Al Gore ask him if he knows the CO2 concentrations in the atmosphere.

Well that wasn’t my intent but thank you for your help. There seemed to be a connection there for me. Perhaps I was mistaken.

Just guessing here, but either filling the uninflated (atmospheric pressure) tire with N2 is "good enough" or they go through an inflate/deflate cycle with N2 until the moisture content is negligible (one cycle should be sufficient, IMO). Probably the former. It's not *that* big of an issue. You just don't want to press a lot of moist air into the tire.

exercise increases CO2. there should be a carbon tax on health clubs, sneakers and treadmills.
