  • EV manufacturers have been searching for ways to make better/cheaper/denser batteries, not better/cheaper/denser lithium batteries.

    Sure, it’s the lithium battery manufacturers that are invested in making better lithium batteries. Everyone has been buying their products for decades and they want that to keep happening, so they pour resources into research and development. And they have a lot of resources, because everyone has been buying their products.

    Once a market settles on a particular technology it becomes self-feeding and tends to accelerate. It’s difficult for a competing technology to break in primarily because of momentum - it’s hard to catch up.

    A device manufacturer might be interested in using a different battery technology, but if they have a whole design and production process already built around lithium batteries then it’s not just the battery that they have to change. It’s their logistics chain, on-device electronics, design theory and possible regulatory concerns. Changing an established system is expensive, so that has to be justified somehow.

    I’m not saying that it can’t happen - I’m sure that it will eventually. What I’m saying is that in order for a different battery technology to really change the market and push lithium out, it will have to be significantly better (not just marginally better).







  • Metronet will be supplying an Optical Network Terminal, probably like this one:

    This is basically the equivalent of a modem for cable networks. It does not provide routing functions. You’re probably stuck with the ONT they supply, but it shouldn’t matter much, definitely not for anything internal.

    It looks like Metronet normally supplies Eero WiFi mesh devices for home networking - are the ones you currently have supplied by Metronet? They might just replace the modem with the ONT and leave the existing Eero gear, or they might upgrade the Eero gear to support the higher speed available on the fiber network.

    In any case, if you are using ISP-supplied network devices then you don’t control the router, which means you can’t set up things like port forwarding to access your home network from outside, or configure VLANs to segregate devices on your network, or control things like DHCP.

    Technically there’s no reason you have to use the Eero devices from Metronet, you should be able to plug any router into the ONT WAN port and have internet service. If you don’t want to get too deep into network config, then any modern consumer WiFi router will work (but not a modem/router AIO device). If you want to have a bit more control, look for one that supports OpenWRT.
