"SUVs spew out 43 percent more global-warming pollutants - 28 pounds of carbon dioxide per gallon of gas consumed..."
Ok I have seen this figure elsewhere. I think it is bogus. A gallon of gas only weighs 6 pounds so how in the he!! could it produce 28 pounds of carbon dioxide? It sounds completely against the laws of physics.
Or in a tree hugger’s world, does the 28 pounds of CO only come out of SUV's?
I don't know, I used to have a 8 pound cat that produced 15 pounds of crap and 12 pounds of hair a week.
Tree huggers should love SUVs, they are pushing out 28 lbs of plant food per gallon of gas.(If those figures are true)
www.fueleconomy.gov has pollution stats on cars and SUVs.
Your cat:
ROFLMAO!
I think I have your cat's brother.
Gosh I wonder how much comes out of private jets of movie stars,or yachts of the rich and famous,or Kerrys SUV,oh thats right it isnt his its the family's.sorry.
A gallon of fuel weighs in under 8 lbs. How they can get 28 lbs of exhaust out of that is beyond me.
A pound of fuel weighs about 8 pounds, but it is mixed with a whole lot of air. Most of the oxygen is burned in the combustion chamber but not all.
SUVs don't burn any dirtier than Yugos, probably much cleaner.
So, I'm wondering. Sometimes my job requires that I go off road with a substantial amount of gear that needs to be secured, rather than exposed in a truck bed. Sometimes my job requires hauling farm feed and gear. Sometimes I just need to get from here to there on the road or with my wife and child.
So does this genius think I should have a pickup, a van, and a touring car? And how much energy was spent and how many pollutants emitted in the making of three vehicles compared what is spent and emitted making one SUV?
Just asking ....
Because it chemically reacts with the oxygen?
Based on the atomic weight of carbon (6) and oxygen (8), even if gasoline were pure carbon, a gallon (which weighs 6.25 pounds) combined with air to form CO2 would produce about 23 pounds by my calculation. So they're off by about 20%.
I think this number is true if you include all the hot air and bullsh-t {methane source} that the left belches out lying about the subject.
It's a mistake, I'd be willing to bet that a typical combustion reaction with gasoline will produce 28 pounds of exhast (I wouldn't be suprised if it's more) if the figures you quote are correct (6lbs of gasoline), if it was pure carbon and assuming we could get the same reaction (C bonding with O2) it would give us 22lbs. based on that if the reaction is compleatly clean (unlikely though) we still have to account for the hydrogen which when burnt off forms another common compound H20. So 28 pounds of C2O is over the top. and I'm willing to bet that a stanard combustion reaction "creates" more than 40lbs of waste vapor (much of that water).
But to find that out would require google and I'm too lazy to either find out the "exact" chemical properties of gasoline, how cleanly it burns, and do the math to figure out exactly how much waste it would create.
How can a gallon of gasoline, which weighs approimately 8 1/2 pounds, produce three times as much carbon dioxide? Unless this is magical gasoline that violates the laws of the conservation of matter, not only is the suggestion absurd, it's impossible. I can't believe that even a green weenie is THAT stupid.

IT REFUTES ITSELF
You got caught by a bizarre misinformation campaign.
Lawn mowers and old cars are terrible sources of pollution. An order of magnitude greater than recent cars. If they were serious about pollution they would have a campaign against older cars and lawn mowers.
They don't.
SUV's are a ruse.
Don't trust anyone.

C+2O---> CO2 ( 12+32=44) X .333
2 Lbs carbon present/gallon requires 10.6# O to form 14.66# of CO2.
I haven't even had to think about Pound-Moles in decades, so I could be off. I could even be off by a factor of two, and that would agree with the figure given
However, given constant stochiometry between IC engines (Not diesel) is should be stressed that no MPG figures are used. Therefore a hybrid will produce exactly as much CO2 per Gallon of fuel.
This all changes if one calculates pounds per MILE, but then if an evil ASSAULT SUV got ten Miles/Gallon, then it would produce 1.46 Pounds of CO2 per mile.
Now, for those who want to calculate the stochiometry of dextrose oxidation, I would dearly love to see how many Pounds Per Mile a JOGGER produces. Or a person on a treadmill. Or me, on my EnviroCorrect™ Specialized trail bike.
As far as I am concerned I would LOVE to have an extra two weeks growing season for my Super Beefsteak VFN Tomatoes, so
