  • I think you are misunderstanding the point. Swap out 9-11 moment with “watershed moment”.

    A drone doesn’t need to be able to carry more than 500-1000g to be an incredibly effective tool of war, and it absolutely was, basically, consumer grade drones that Ukraine used.

    And all in all, probably, the whole operation cost less than a single tomahawk cruise missile.

    I made this point that the article is making here, a few months ago. The US military industrial complex has completely missed the mark on where modern warfare is going., and the US has spent trillions to build a system that can be challenged for billions.











  • We saw a USB pack similar to this released by a Japanese company earlier this month.

    If these prove to be as viable as they appear to be, the age of oil is over, because as interesting as these may appear for vehicles, mobile-ish electronics (read, they aren’t great in terms of energy density), where they’ll shine is immobile grid scale or structural scale or immobile device scale storage.

    Your oven might end up with a bank of these. Your fridge. An air conditioner. A heat pump. A power wall for your house that holds 4 days worth of electricity. These have way way way higher cycle reliability than their lithium counter parts. They’re good for something like 5x-10x as many cycles. But they are heavier per unit energy. But they degrade slower.

    I’m trying to not get to hyped but the bits of news of these getting into consumer technology is extremely heartening. The biggest and frankly, only middling issue, with renewables is where to stick the energy in the between times. Grid scale or microscale storage is the answer, but honestly, lithium hasn’t been a great technology for that. Its good enough to get started, but the cycle time isn’t great and the consequences of failure are high. Lithium fires arent nothing to fuck with.

    As far as I know, these sodium batteries basically can’t catch fire the way lithium can. There is no thermal runaway potential.

    They don’t consume (as much) hard to get, planet destroying minerals like lithium or cobalt.

    They’re very young, but even in these first generations, are coming in price competitive with lithium comparables. Remember how expensive lithium was in its first generations?

    We’ve already spent a few decades setting the world up to run on lithium batteries. Sodium should be a drop in replacement.


  • Too many cooks: Handwringing. Whataboutism.

    The authors misunderstand how to think of the (and even) elements of the fediverse. It’s still taking a competitive view/ worldview/ framing, and when that’s all you understand, sure. But the right way to understand the fediverse is as protocols, like email, and each branch as a flavor of email, or some other misguided metaphor. And it’s it’s only a problem when infinite growth or exp. scaling is your goal. However if neither of those things are your goal, it’s more of an annoyance.

    Commercial capture: More handwringing. Misidentification.

    Meta took a crack at capture. It didn’t seem to have worked. The fediverse is populated by the leavers, not the takers. The Internet happens at the edge and the normies are always just catching up a few years too late. The point of the fediverse is that it’s a extraordinarly easy to vote with your feet. If the fediverse can fall victim to a 51% attack, fine, well just leave and do it again.

    Guilty by association: Again, more handwringing. Also, we should do that.

    Federated p2p file sharing e2e file sharing for unsavory bits that governments and corporations don’t want you to have sounds like a great idea.

    It’s in the CIA field manual, that when you want to destroy an organization from within, urge caution, and question every unfounded problem.
