whats going to replace copper?

[ldisplay]

ok lets face it copper is really expensive now, and eventually ou supplies will run out. Aluminum could be used again but it has the prone to be a problem again.

There has got to be something to replace copper that is cheaper/better to use.

Well, from what I remember in college, your list of best and going downhill from there goes something like this: silver, copper, gold, aluminum, calcium & tungsten. I may have missed one or two before tungsten.

As you can see if you trust my memory, Silver is the best conductor we have but like gold and the other , its just not practical to use.

I personally dont even speculate where the market is going, but I do not look for copper to go anywhere (but up in price), I do believe it will eventually settle. I would not hold my breath for the $30.00 250' roll of 12-2 w/ground however.

We could follow the lead of much of the world and double the voltage, thus cutting the copper content of wire in half. Would be a big undertaking.
