  • to my knowledge, the only place they use aluminum as a conductor is in overhead external transmission lines, because you can wrap them around a steel or fiberglass/carbon fiber core (due to the skin effect this incurs minimal losses) while increasing strength and reducing weight (with the composites at least)

    the secondary reason is because you can just use more aluminum, since it’s not nearly as dense as copper, and also allows you to string farther, since again, not nearly as dense.

    most aluminum wiring is actually cladded in copper, it’s called CCA for what should be fairly obvious reasons.

    Also i believe the oxide coating of aluminum isn’t conductive? The bare material itself is, but once it oxidizes it’s probably not a good conductor, this is why we use shit like gold plated contacts. Copper also oxidizes as well, but it’s not nearly as bad.












  • yeah idk, to me bystander is like that one guy in that one mall in indiana who managed to shoot an active shooter. You mean to tell me these people aren’t real and don’t exist? I’m not surprised.

    Or just like, some dude walking by a crime actively happening. To me the individual being criminalized on, the victim, if they were to own a gun, i would think this stat would be a lot more likely.

    This also ignores the actual point of things like conceal carry, if you open carry someone probably won’t try to rob you or mug you at all, which is going to be a statistical anomaly, you aren’t supposed to use your gun unless you absolutely need to, if that means handing over your wallet and cancelling your cards, so be it, at least you didn’t kill someone.

    It’s really only meant to be for the 0.1% of cases where it might actually be required.
