Who reads this anyway? Nobody, that’s who. I could write just about anything here, and it wouldn’t make a difference. As a matter of fact, I’m kinda curious to find or how much text can you dump in here. If you’re like really verbose, you could go on and on about any pointless .….[no more than this]

  • Here’s my favorite part.

    “In addition, the conversions were sometimes not even self-consistent and applied completely arbitrary. The 3½-inch floppy disk for example, which was marketed as “1.44 MB”, was actually not 1.44 MB and also not 1.44 MiB. The size of the double-sided, high-density 3½-inch floppy was 512 bytes per sector, 18 sectors per track, 160 tracks, that’s 512×18×16 = 1’474’560 bytes. To get to “1.44” you must first divide 1’474’560 by 1024 (“bEcAuSE BiNaRY obviously”) to get 1440 and then divide by 1000 for perfect inconsistency, because dividing by 1024 again would get you an ugly number and we definitely don’t want that. We finally end up with “1.44”. Now let’s add “MB” because why the heck not. We already abused those units so much it’s not like they still mean anything and it’s “close enough” anyways. By the way, that “close enough” excuse never “worked when I was in school but what would I know compared to the computer “scientists” back then.

    When things get that messy, numbers don’t even mean anything any more. Might as well just label the products using entirely qualitative terms like “big” or “bigger”.


  • The main idea here is that we won’t run out of raw materials very easily when using stuff that’s relatively cheap and abundant. Well at least the ions are. Who knows what the anode and cathode are made of. Probably the usual materials; otherwise they would have mentioned it. If they still use cobalt in the cathode, you can’t really avoid the ethical questions that come with it.

    Producing all the other materials can be rather energy intensive depending on the method used, so it depends. If you buy your metals from a country with hardly any environmental regulation, you can be pretty sure they don’t give a dingo’s kidney as to how many trees are chopped down and how many puppies are thrown in a furnace to get the next shipment of metals delivered.

    Also, the electrolyte could be more or less harmful to humans and the environment. As far as the environmental impact is concerned, these batteries probably come with all the usual issues. Currently there just aren’t any perfect solutions commercially available. Regardless, this seems like a step in the right direction IMO.
