At a utility a friend of mine worked at they found a halfway house sourced day laborer who stopped showing up to work the week before.

He was in the basement with a literal death grip on a hacksaw attached to a bus bar.


The funniest thing I ever saw on television was a security video of a man using a warehouse loader to drop a 20,000 pound coil of copper into a small Toyota pickup truck that was backed into the dock.

'Remember how last year we heard of discoveries that about doubled our estimated oil in the ground?'

Fact: Oil production peaked in--quoting from memory--1971. It has fallen steadily since and will continue to do so. Doubling or even quadrupling the miniscule fraction that is known to be in the ground pales against what has already been used and demand that is rising at such a rapid rate. It's not quite as bad as 2x0=0, but it's not good either.
You're also faced with difficulty of retrieval, sulfur content, percentage that can be refined into gasoline (not all crude is equal in this), ground subsidence (one of the two prime factors in New Orleans falling below sea level is pumping of oil [the other is the levee system which is keeping sediments from rebuilding the delta, but we'll leave that for another day]--does anyone care to calculate the indirect cost of the oil that was pumped from beneath Louisiana once New Orleans is rebuilt?), and on and on and on.
You'll note that I didn't even mention environmental degradation, pollution of ground water, global warming, etc. It's not politically correct to mention such things.
And do you really want to give the oil-rich countries that much political leverage?
Here's another factoid to put in the back of your mind: Let's assume for a moment that our national economies weren't predicated on burning hydrocarbons. Let's assume that petroleum has just been discovered. No rational, intelligent being would do something so foolish and wasteful as burn it--they would use it as feedstock for plastics and for drugs. There will eventually come a time when people look back and say,"You did what with all that petroleum? You burned it? Look at all these other incredible things you could have done with it and you burned it?"
Let me put it this way. Suppose you're marooned on an island. You've got a small stand of trees. Thirty, perhaps. Let's say they're coconut trees.
Do you:
A) Cut them down and burn them at night for warmth and light?
B) Cut them down and build a house so that you have shelter?
C) Eat coconuts for nourishment. Weave the coarse hair from the outside into crude clothing to protect yourself from the elements. Burn the shells for warmth and scatter the ashes under the trees as fertilizer to encourage the trees' growth?
"A" provides immediate gratification, but you'll soon be out of trees to burn and no more will grow. "B" takes a little more work, but provides something of longer term value--although you'll lose it the next time there's a hurricane/typhoon or tsunami and you'll be in just as bad a shape as in "A." Note that in either "A" or "B" you will starve to death fairly soon no matter how many coconuts you had stored when you cut the trees down. "C" clearly requires the most work, but will keep you alive the longest. The trees will even give you something to cling to when the waves come it, thus perhaps saving your life in a more dramatic fashion.
Current policies in most nations are a combination of "A" and "B." They pay lip service to "C" but don't actually do much about it.
Now, back to copper.
Copper is readily converted to salts (chlorine and sulfur are the primary dance partners). These salts are soluble in water and will leach away. Where do they end up? In the ocean. Dilute. Past reasonable reclamation.
Can copper be recycled? Obviously. But as a simple matter of thermodynamics, no process is 100% efficient and the loss in recycling programs is horrendous. As an example, here at work we have recycling bins for aluminum cans. They are on every floor. In many cases they stand right next to the trash cans. And yet people will throw aluminum cans into the trash even when there is a recycling bin right next to the trash can!
Copper is no better. I see copper wire in trash cans, being thrown away.
Please, people...think before you speak. Be careful where you get your facts. Getting your science from a politician is like asking your garbage collector for stock tips. Not a particularly bright thing to do. Your information comes from a scientist? That's a start, but ask who is paying his/her paycheck. Did no one learn from the tobacco companies? For years, absolutely everyone said that smoking caused cancer, heart problems, you name it. Except for a few who said that there was no evidence that tabacco caused any such thing. And who paid the nay-sayers' paychecks? Why, the tobacco companies! Golly, what a surprise! If the bread on your table comes from a tobacco company, you're going to be reluctant to bite the hand that is (literally) feeding you. The majority of the scientists who are now saying that global warming isn't a real problem are paid by...
(whisper it...)
the energy companies.
Some things never change.

How to use copper more efficiently - Increase supply voltages.

4R speaker drivers are a crazy idea

The automotive industry uses a lot of copper and they are about to move cars from 12V to about 40V, this will be done to save weight and space and indirectly use a lot less copper

Back in the 70's we heard the same jibberish.

There is no shortage of oil.
There is no shortage of copper.
There is no shortage of greed!

Stocker, I guess you can say whatever you want, as you already live in Texas.

Aaaaahhhh ye-eeeessss. I almost forgot.

If we're so concerned about burning oil, why not all pay a visit to the watercar webpage and find out how to convert our cars and other internal combustion engines to run off on-demand low-pressure hydrogen generated from ordinary water?

Let's not even mention who is trying to suppress THAT sort of thing...

Hmmm... ith all the loose wires around here, it's no wonder that Nixie believes we're running out of copper. Besides, the only way to get truly oxygen free copper is to open-pit the Moon.
