Its silly to think that copper itself is going away simply because the phone system won't be using much of it anymore, almost all electricity from AC to DC wire

Its silly to think that copper itself is going away simply because the phone system won't be using much of it anymore, almost all electricity from AC to DC wires run over copper and various alloys.
- chrisper 9y agoAlso all Speaker wires are copper.
- microcolonel 9y ago> ...almost all electricity from AC to DC wires run over copper and various alloys. Aren't most OPLs aluminium these days?
- icantdrive55 9y agoYea, copper and it's alloys are relative cheap. Aluminum wire did not work out for residential/commercial wiring. It's going to be here for awhile.
- HumanDrivenDev 9y agoBy AC to DC wires, are you referring to your typical laptop power cord? IE, copper from the wall to the transformer/DC converter, then copper to the power supply of the laptop? I remember having an labouring job installing power supply cable underground. It was all aluminium, and you rolled it off a giant spool because you could barely bend it.
- colechristensen 9y agoPower lines for the grid are generally aluminum. You'll generally only find copper in consumer goods and the walls of your house. You can get aluminum wiring in your house but there are details that require more installation expertise to do it safely so copper is used instead.
- ztjio 9y agoThis isn't about all copper wire. It's using copper to refer to the old copper wire based POTS.
