Interesting point...Tanada wrote:Yes, some of the newer homes around here are being built with
PVC because it has no scrap value so their is not the same fear of

It is possible to substitute copper wire with other metals, likeTanada wrote:You know inside your house there is no reason you couldn't
substitute steel wire for electric service and plastic pipes for
water and sewer, but people are reluctant to change from what
they are used too.
Copper building wire requires less insulation and smaller
conduits than aluminum because aluminum, with its lower
conductivity, must be larger in diameter than copper to carry the
same current. This is why more copper wire can fit in a given
conduit, compared to aluminum. This greater “wire fill” is a special
advantage when a system is rewired or expanded. Another
advantage is that copper oxide also conducts electricity. So
connections and terminations will not overheat and do not require
the use of oxide-inhibiting compounds. In addition, copper also
provides superior thermal conductivity (60% better than aluminum),
which saves energy and accelerates heat dissipation. This property
is also especially helpful at terminations and connections.

abandoned water heaters and scrap we see littering the country side and river banks will start getting picked up!

Our infrastructure is being raped by the same global capitalist/corporatist system that helped European and American pirates, vandals, imperialists rape the old colonies of their mineral and other resources. So do we just follow the old advice to rape victims: "Lie back and enjoy it"?

I dunno. It's the same reason all the pyramids and greek ruins are in the shape they're in. In times of scarcity, the past gets recycled to meet the needs of the present.

I don't think that's the case for wiring, unless somebody wants to point me to a page that discusses why steel is just as good.
