  • it’s a flow battery, so it keeps charge basically indefinitely (when not in use energy-bearing parts are separated). you can run it as hard as you need and it will not degrade in use-dependent way, at least not as hard as lead or lithium batteries

    to elaborate on durability, there’s no capacity loss with these batteries. so if design intention is to run these batteries from full to empty and back every day, and maybe a bit more* they can handle it no problem, because everything that happens, happens in liquid phase that can’t degrade. lithium battery will degrade fast with such usage, but this one won’t. on balance, there’s need for pump and electrolyser maintenance, but at least you won’t need to rip apart everything and replace all batteries every 3 years. per kwh per year of use it might be cheaper this way

    * they might want this battery to provide energy in the morning, before solar panels kick in, soak up excess energy from noon peak, then discharge it in the evening. that might be 500ish cycles per year, and they can run it at full tilt









  • users [can] retain access to messages even after logging out of the platform
    

    This sounds great. Nothing bad could happen here. I’m sure the people developing this are competent.

    the article says:

    Further, if users want to retain access to messages even after logging out of the platform, they must set up a recovery key, which the installation manual suggests storing in a password manager.

    this is standard matrix thing. if you log out of matrix and don’t do that, you’re greeted with Unable to decrypt message after next login. this is because it’s on-prem matrix instance (or instances) with mandatory 2fa (freeotp is an option) and registration process tying matrix identity to national id, and it’s intended only for public administration internal use. you can’t just walk up and register you have to work there, and as their threat model is about phishing, this does make sense
