    hey it has been 15 years

  • What is this publication and who finances it because this section is incredibly sus:

    Copper use is not carved in stone. Hybrid cars, which pair small batteries with gasoline engines, need far less of the metal than fully electric vehicles.

    Power grids that mix nuclear, wind, solar, and a pinch of natural-gas backup can slice the copper bill dramatically compared with battery-heavy systems.

    “First of all, users can fact-check the study, but also they can change the study parameters and evaluate how much copper is required if we have an electric grid that is 20% nuclear, 40% methane, 20% wind, and 20% hydroelectric, for example,” Simon said. “They can make those changes and see what the copper demand will be.”

    Like you think we can transition to an increasingly electrified world, where all power comes from electric utility lines, and you think our copper usage will be ... just in renewable power plants?

    This reads like straight fossil fuel propaganda. In an electrified future the majority of copper use comes from distribution lines and products that use electricity not the type of power plants generating electricity.

    You're wrong in terms of long distance power lines being mostly copper, but this does seem a lot like fossil fuel propaganda.

    Motors, generators, and transformers can be built using aluminium; they're just a bit bulkier and less efficient. Very common practice.

    It looks like CCA might be making its way back into house wiring in the near future, with much lower risks than the 70s aluminium scare.

    The big thing is that batteries really should be a last resort, behind demand response (using power when it is available, rather than storing it for later), long distance transmission, and public transport instead of private vehicles.

  • That alternative material is aluminum. It's like a top four abundance material in the crust. It's just super fucking hard to refine from minerals that don't like to give it up without oodles of energy. Like, turn minerals into plasma levels of energy. So the irony is, to grow our energy economy past the need for copper, we will first need to grow our energy economy.

    Should fusion ever actually meet its promise, then this is one of the likely things we could do with this level of energy.

    If we ever become a spacefaring civilization, it'll almost certainly be necessary during the colonization of other planets/moons/asteroids, since the geological processes that concentrate copper on the earth are not present in those places. Whereas aluminum is plentiful any place rocky.

    Aluminum expands under electrical loads and the wires become loose. Loose wires are a fire hazard.

    The real solution is steel wire with a copper coating. Electricity flows on the outer region of wires anyhow.

    Heh. My batteries are flooded lead-acid, all 1320ah of 'em. No copper guilt here.

  • Perhaps it’s time to start researching alternative materials.

    Perhaps it’s time to start researching alternative materials.

    Plenty of metals floating around in space. Just need to go and get them.

    Only need to capture one decent sized metalliferous asteroid from a near earth orbit and we'd be set for a century or two.

  • This all suggests that we keep producing, wasting and manufacturing things infinitely without ever recycling, reusing or re purposing everything that we are mining out of the ground. The article notes that this includes recycling but only at the rate we have now.

    If we keep running our world the way we are now for the next hundred yes .... than yes, we are going to run out of everything because we live in an absolutely wasteful society that only runs in a way to produce things designed with planned obsolescence to break down in a short amount of time so that we can produce more junk to sell and drive a stupid economy to make a small group of idiots even more wealthy. The whole system is designed to run on making infinite money by producing infinite junk that doesn't last long.

    Yes at the rate we are going and the way we are producing things and the way we shape our economy and the way we base our manufacturing .... we are definitely going to run out of everything.

    We can change our economy and the way we produce and manufacture things - and get rid of this stupid structure of society of just endlessly making money for a small group of morons .... or we can keep doing things the way we are now until we run off a cliff and destroy everything and drive our species into extinction.

    The article notes that this includes recycling but only at the rate we have now.

    The original study says they assumed an annual increase of 0.53% as observed over the last 20 years.

  • I remember when phone lines were made of copper. We were sure that it would be impossible for everyone to have a phone.

    There's a lot of copper pairs left underground. Many hundreds of thousands of kilometres of it. Use it as a pull-through for fibre-optic bundles, and everyone can have gigabit internet.

    Seriously though, there'll come a time when that underground obsolete copper will become economic to retrieve.

    All kinds of copper are economic to retrieve with enough crack

    This was my first thought, we aren't going to develop the whole world. That's not how this works. Who said that was a goal of... well ... anyone's?

    That's a rhetorical question. Frfr tho, does that remind me work on your instance only, or what's the deal with that?

    This isn't a big thing. This is a constant thing in every system. It's the push and pull between efficiency and resiliency. More storage capacity is less efficient when things are going well, but is more resilient and adaptable when they're not.

  • The original study abstract is a little more clear. The main concern is grid storage batteries and EV batteries.

    Given that the sharp increase in copper demand is primarily driven by batteries, the extra copper needs for electrification can be significantly reduced if the need for electrical storage is minimized. This can be achieved by generating electricity through a mix of nuclear, wind, and photovoltaics; managing power generation with backup electric plants fueled by methane from abundant resources of natural gas; and transitioning to a predominantly hybrid transportation fleet rather than fully electric vehicles.

    Or you use pumped hydro, or compressed air, or gravity batteries, or any of the other energy storage technologies that aren't chemical batteries.

  • Your argument against the article that talks about copper usage is founded on incomplete knowledge of where copper is actually used?

    🤦

    It's founded on the article not making a cohesive argument. Current copper usage is primarily in consumption and distribution, not generation.

    When we run out of things, it's we who run out of things but not those with power to get what they need and kill excess population.

    So preaching to them is useless.

  • Aluminium is very commonly used. It isn't near as good a conductor as copper, but you can easilly use more toeget results and in most cases that works fine.

    The reason we stopped using aluminimun more is it is relly tricky. when you tighten a screw the al deforms over time and so you don't get a lasting connection. Al also corrodes to a non conductive state. Many house fires were traced to al wiring in just the few years it was common. We can mitigate all the above issuses but it takes care and so copper is preferred despite al being much cheaper.

    Aluminium conducts better per weight. Copper per volume.

    1. The article is shit, the study is about copper used for reducing fossil-fuel power generation. It is basing the projected use of copper on windmills and especially large batteries.

    2. Those high-powered and long distance power lines are made aluminium and steel.

    1. Distribution doesn't just include long distance distribution. It includes all the wiring between transformers and houses and all the internal wiring of the house and all the devices inside etc.
  • They stopped putting aluminum in homes, because it has a tendency to overheat more. The aluminum expands and contracts with load more than copper, which can loosen contact points and encourage oxidation, which then increases resistance and heat. Hot wires in the walls and outlet boxes are no bueno.

    only residential wiring uses copper, everything from 350kV down to 400V lines is aluminum, and even in houses aluminum can be used too

    Yes, but big batteries everywhere is going to effect that if there's copper in lithium batteries, and apparently there is.

    This isn't a big thing. This is a constant thing in every system. It's the push and pull between efficiency and resiliency. More storage capacity is less efficient when things are going well, but is more resilient and adaptable when they're not.

    Excess storage capacity, sure.

    But inflating the base battery capacity to cover people having showers at 5pm because it's easier than storage water heaters and time/remote controls is stupid. You can reduce the base need for batteries by reducing the need for electricity in the first place and reducing the use of vehicles that need to carry batteries in place of e.g. overhead catenary.

    1. Distribution doesn't just include long distance distribution. It includes all the wiring between transformers and houses and all the internal wiring of the house and all the devices inside etc.

    And that part is entirely independent from whether the electricity is generated with solar, wind or fossil fuels.

    What I'm speaking about is that it should be impossible to do some things. If it's possible, they will be done, and there's nothing you can do about it. To solve the problem of twiddled social media (and moderation used to assert dominance) we need a decentralized system of 90s Web reimagined, and Fediverse doesn't deliver it - if Facebook and Reddit are feudal states, then Fediverse is a confederation of smaller feudal entities. A post, a person, a community, a reaction and a change (by moderator or by the user) should be global entities (with global identifiers, so that the object by id of #0000001a2b3c4d6e7f890 would be the same object today or 10 years later on every server storing it) replicated over a network of servers similarly to Usenet (and to an IRC network, but in an IRC network servers are trusted, so it's not a good example for a global system). Really bad posts (or those by persons with history of posting such) should be banned on server level by everyone. The rest should be moderated by moderator reactions\changes of certain type. Ideally, for pooling of resources and resilience, servers would be separated by types into storage nodes (I think the name says it, FTP servers can do the job, but no need to be limited by it), index nodes (scraping many storage nodes, giving out results in structured format fit for any user representation, say, as a sequence of posts in one community, or like a list of communities found by tag, or ... , and possibly being connected into one DHT for Kademlia-like search, since no single index node will have everything), and (like in torrents?) tracker nodes for these and for identities, I think torrent-like announce-retrieve service is enough - to return a list of storage nodes storing, say, a specified partition (subspace of identifiers of objects, to make looking for something at least possibly efficient), or return a list of index nodes, or return a bunch of certificates and keys for an identity (should be somehow cryptographically connected to the global identifier of a person). So when a storage node comes online, it announces itself to a bunch of such trackers, similarly with index nodes, similarly with a user. One can also have a NOSTR-like service for real-time notifications by users. This way you'd have a global untrusted pooled infrastructure, allowing to replace many platforms. With common data, identities, services. Objects in storage and index services can be, say, in a format including a set of tags and then the body. So a specific application needing to show only data related to it would just search on index services and display only objects with tags of, say, "holo_ns:talk.bullshit.starwars" and "holo_t:post", like a sequence of posts with ability to comment, or maybe it would search objects with tags "holo_name:My 1999-like Star Wars holopage" and "holo_t:page" and display the links like search results in Google, and then clicking on that you'd see something presented like a webpage, except links would lead to global identifiers (or tag expressions interpreted by the particular application, who knows). (An index service may return, say, an array of objects, each with identifier, tags, list of locations on storage nodes where it's found or even bittorrent magnet links, and a free description possibly ; then the user application can unify responses of a few such services to avoid repetitions, maybe sort them, represent them as needed, so on.) The user applications for that common infrastructure can be different at the same time. Some like Facebook, some like ICQ, some like a web browser, some like a newsreader. (Star Wars is not a random reference, my whole habit of imagining tech stuff is from trying to imagine a science fiction world of the future, so yeah, this may seem like passive dreaming and it is.)

    I share your frustration. I went nuts about this the other day. It was in the context of searching on a discord server, rather than Google, but it was so aggravating because of the how the "I know better than you" is everywhere nowadays in tech. The discord server was a reading group, and I was searching for discussion regarding a recent book they'd studied, by someone named "Copi". At first, I didn't use quotation marks, and I found my results were swamped with messages that included the word "copy". At this point I was fairly chill and just added quotation marks to my query to emphasise that it definitely was "Copi" I wanted. I still was swamped with messages with "copy", and it drove me mad because there is literally no way to say "fucking use the terms I give you and not the ones you think I want". The software example you give is a great example of when it would be real great to be able to have this ability. TL;DR: Solidarity in rage

    While I completely agree with you about the absence of one-liners and meme comments, and even more left leaning community, there's still that strong element of "gotcha" in discussions. Also tonnes of people not reading an article before commenting (at a better rate than Reddit probably), and a generally even more doomer attitude is common here.
