Again, it refers to what it takes to PRODUCE the concrete. The base materials are baked at a very high temperature before the mixing product results for use down at the concrete and gravel pit.
THAT'S A GOD DAMNED MYTH AND IT'S NOT TRUE!!! EITHER POST FACTS OR GET LOST!

You two haven't heard of Trump's latest solution?
BOTH Democrats AND Republicans will be happy!
Illegals will be issued Green Cards valid ONLY in sanctuary cities/states.
Arrest, castrate and deport if caught anywhere else.
Benevolent states, such as Arizona, will compromise and ship all their illegals to Massa2shits >:-}
You will be so-o-o-o happy... your economies will thrive... all work will be performed by your new "service" class ;-) ...Jim Thompson

ould be hopelessly ineffective and the environmental damage would be huge.
Believe it or not, the military is not the last word on climbing technology . Almost everyone knows they're 10-20 years behind the curve in all they do , and any advances they make are by adopting technology and techniques from the civilian recreational industry. Any arborist can tell you in 5 seconds how to get over that joke using low tech gear like ropes, and, if you go m echanized, a bucket truck on the Mexican side will make even shorter work o f it. You've been conned, brainless.
Here's another one for you, stupid:
So once the point man breaches the wall and sets anchors on the opposite side, any number of rope ladders and inflatable chutes can make easy work of getting over by the less able people.

That's not how carbon footprint is computed, MORON. The calculation compute s all the energy required to quarry, transport, heat, pulverize and even mo re transport of all the raw materials into a finished product, MORON. All t hat does not come free and requires fossil fuel energy and hence greenhouse gas emissions, MORON.
I've not seen that thread. But for once you did ask :)

funny how people talk about eh carbon footprint of a wall yet no mention of the carbon liberated by continuing to guard it without a wall.
And no, I'm not going to takes sides on the wall.

That may be what they meant, but not what they said. THey said a kilo of steel embodied 1.8 kilo's of CO2.

NOT "embodied". More like "Total cost to produce".
So it "embodies" it ONLY from a COM POV. DIG?

Dan has difficulty with complicated ideas. The 1.8 kilograms of carbon diox ide emission "embodied" within a kilogram of steel are not physically conta ined within the steel itself, but reflect the carbon that had to be become CO2 to transform the original iron ore into that kilogram of steel.
Fe2O3 (ferric oxide) contains two atoms of iron (atomic mass 55.845) per th ree atoms of oxygen (atomic weight 16) so it takes 1.43 kilograms of iron o re to make one kilogram of steel. That 0.43 kilograms of oxygen has to be c ombined with 0.16 kilograms of carbon to get it off the iron, generating 0.
59 kilograms of CO2. You have to get the iron ore and the coking coal quite hot to get this to happen - in fact the oxygen initially comes off as carb on monoxide - and you get this heat by burning more carbon than is strictly required by stoichiometry.Dan may have studied science at a high prestige university, but doesn't see m to have retained much of what he was taught. The word prestige does come from a French root meaning deceit or delusion.

Yes. But speaking of walls, don't we have lots of walls already in place, and upgraded in many places? Trump talks like there aren't any walls at all now. They've found tunnels 100-feet deep and a mile long, so higher walls can't work in high-traffic locations.

Hadrian's Wall is still standing. The Scots don't use it to keep out undesirable immigrants (and Cursitor Doom would clearly be one of them) but they don't need to - the Scottish climate does it for them.
I was once in Scotland when the sun was shining - it doesn't happen often - and went around telling the locals that I was there "last week" in payback for the times that they'd told me that I should been there the previous week ...
