“Just to meet business-as-usual trends, 115% more copper must be mined in the next 30 years than has been mined historically until now,” the study said.

    Its almost like the answer isn’t some whimsical butler just for you, but fucking public transportation. Build fucking trains.

      Agreed. I love trains and it frustrates me to see them bungling the implementation. When they try, they always seem to make the same mistakes trying to bring it to my area.

      To see meaningful ridership out here, the train needs to go fast enough to negate the penalty you get at the other end when you have to go from the station to your destination. They wanted to run them at ~55-70mph here, with a few stops between major cities, to parallel a freeway that is 65-75mph. Drive 1 hour (1:10 with parking) or spend 2 hours going to the station, riding a slow train, then going from the station to where you are going? I hate cars, but as someone who only gets a handful of hours to myself after sleep, work, and chores, I’m going to save my time and pick the car. If they ever build the train, as it is planned right now, it’ll just be another commuter train that’s only really used at rush hour when the roads are jammed rather than an all day all week car replacement solution that I can ride to Sunday night dinner at a friends house as easily as a 6am meeting.

        @njordomir @Sanctus The safe money is it will also run too infrequently to be a good replacement. Adding ‘time waiting for train’ to the picture for trips outside of 6~9am or 3~7pm and officials wonder why services aren’t well used.

          Interestingly, a similar problem as with bike infrastructure. The infrastructure isn’t useful until a lot of it is built and it connects everywhere (and timetables get shorter for trains). The infrastructure won’t pass public opinion until it’s proven to be useful to people. I will always vote yes on funding these projects even if I think they will bomb because it puts us a little closer to the peak of that hill. Its still frustrating though. We could easily do like we did with the freeways if we just decided it was worth building.

    They’ll start mining landfill for metals and probably plastic soon enough. Air it out, wash it, get the metal and plastic, don’t worry about that other in the air/water, that’s a future poor person’s problem.

      metals, sure. The problem with plastics is that plastic is not plastic, it’s a plethora of different chemical structures. Very difficult to recycle some of them, even if sorted.

        It’s somewhere between 100 and 150lbs saved per car.

        There’s a lot of copper in the wiring harness and it’s most of the weight. It’s also a reduction in the plastic around the wires, the other weight contributor.

        Edit: For EVs anyway, my bad. Probably less copper in non evs, but still a lot.

          @NotMyOldRedditName Are power carrying wires the bulk of the wires in a car?

          And by power I mean more than 5W where wire gauges start to get serious at 12V. An indicator LED is technically needing power, but not enough that wire gauge bulks up.

            Wiring harnesses from traditional automotive companies are quite long. This is quote from Ford’s CEO

            ““We didn’t know that our wiring harness for Mach-E was 1.6 kilometers longer than it needed to be. We didn’t know it’s 70 pounds heavier and that that’s [cost an extra] $300 a battery,””

            4km is normal

            https://q5d.com/escalating-function-dilemma/

            "Some modern vehicles contain close to 40 different harnesses, comprised of roughly 700 connectors and over 3000 wires. If taken apart and put into a continuous line, these wires would exceed a length of 2.5mi (4km) and weigh approximately 132lbs (60kg). Five years ago, vehicles had 25% less circuits than today’s cars. Five years from now, that number will increase by more than 30%. "

                Fair, but you can’t do 12v ethernet like they’ve done with 48v. The cables would be too big

                So unlocking 48v allowed the change which allowed lesser cabling.

                Tesla claims it’s 77% cable reduction and 50% copper.

                Edit: also Teslas wiring harnesses have been smaller than industry standard for years. If others made the switch and moved to an etherloop as well, the copper savings would be even bigger than what Tesla experienced.
