  • The price has nothing to do with patents, it's economy of scale - LCDs ship at a rate of billions per quarter, and are included in every device under the sun, whereas e-ink screens basically only ship in niche luxury devices (ereaders/enotes) that can be replaced by your phone and an ipad respectively. As a result, LCDs ship several orders of magnitude more screens, and reap the resulting economies of scale.

    Yes, EInk corp has patents, but that doesn't prove that the price is caused by the patents.

    Currently, our best hope of seeing prices come down is 1) if the fast-multidye tech (i.e. the Gallery 3 thing) takes off enough to give e-notes mass market appeal (color drawing and comic book reading could be huge, maybe) and thus some extra economy of scale, or 2) if GoodDisplay's DES screens get their PPI up to 300 and thus are able to compete in the ereader space against E-Ink's MED.

    DES = Display Electronic Slurry, AKA the cofferdam tech. It's a different method of creating an e-ink screen that (apparently) doesn't touch E-Ink's patents, and it works by creating a grid of ditches to be filled up with the e-ink liquid and ink (where 1 ditch = 1 pixel). In contrast, E-Ink's MED (=Microencapsulated Electrophoretic Display) produces self-contained microcapsules that have the liquid/ink sealed inside, and then the microcapsules are sprinkled onto the screen's pixel grid like Hundreds And Thousands, and each microcapsule is substantially smaller than a pixel, and each pixel toggles several microcapsules. The microcapsules sometimes overlap the border of the pixel grid (since they're a bunch of packed circles basically), which breaks up the straightness of the pixel grid and is what gives E-Ink screen their 'grainy' look where DES screens are more noticeably checkerboarding. This could potentially give MED a long-term aesthetic advantage, although that might turn out to be a non-issue for DES with sufficiently high PPI.

    The advantage of DES is that because it skips a layer (the slurry is directly on the substrate, rather than in microcapsules on the substrate) it could potentially be higher-resolution(/PPI), and higher contrast. Also possibly cheaper, since it might be able to skip a manufacturing step of making the microcapsules. Maybe.

  • I don’t know what he considers waste, but there’s a ton of obvious waste, such as military suppliers

    That's likely an accounting quirk you linked: if they list 9 screws and a tank for $1M but don't specify individual prices, in some situations they just approximate it by assuming they cost the average - so they assume the tank costs $100k and each screw costs $100k each.

  • How much obsolete tech does the WW2 infantry have, is the question - e.g. if it's US troops then they'll have Garands, which are only obsolescent, and they only need to stall until the modern air force can come help.

    ...actually, no. The modern air force could split up, put 10%ish of its forces into ROFLstomping the WW2 air force and the other 90% into supporting the WW2 infantry. So the WW2 infantry will always have air support from the moment the war starts. If the air force can obliterate a few platoons of modern infantry, then the WW2 infantry can scavenge some of their equipment and level the playing field a bit.

  • Aren't those planes brought up to the air by actual planes? If modern planes have air dominance, then those plywood planes had better have a functioning plywood engine because there won't be anything else to get them skybound.

  • If the modern air force can take out some modern ground troops, the ww2 ground troops could loot their corpses to be somewhat modern-ish ground troops. The modern air force could use radio to explain how to use the equipment, if they have access to wikipedia.

  • The European and Japanese cities featured in this article as exemplars evolved they way they did under severe feudal land restrictions

    Ok, how about the city of Pompeii (which was entombed by the volcano in ~50BC), or Tenochitlan/Mexico city (which was built before European contact, or the city of Cusco (ditto), or the city of Petra (which had plenty of spare desert)? Or Venice, or Mateba, or pick-a-town-any-town.

    What "severe feudal land restrictions" do you mean? Can you elaborate?

    Here on slrpnk.net I see quite a few "new urbanists" endorsing solarpunk visions with wide streets. I posted this partially in response to that.

    I could link a newer article, but this one works just fine. Articles don't have an expiry date, if you have an actually valid criticism then say it.

    If it helps, replace "organically" with "incrementally and due to decentralized choices".
