    Article states the use of an electron beam to enable this. So not currently scalable, but still a seemingly significant result.

    1k mile or kilometer range? Which is it? I’m inclined to believe it’s kilometers. Time to read the article, I suppose. It’s enticing either way.

      A bit misleading but yes, 1000km is what they are talking about. Also the article doesn’t address scalability.

        Well, there’s a lot the article doesn’t address. I can say this with complete confidence, even as someone who hasn’t read the article

        Edit: don’t freak out, I eventually did read the whole article. Every word. And I was right.

      They demonstrated 40% increase in energy density.

      The stuff about the range appears to be simply applying that percentage to common EV ranges, which is nonsense. It’s probably more likely that an increase in energy density would be used to decrease battery size, leading to cheaper and lighter EVs

    Sodium is the future of batteries right now.

    Projections from BNEF suggest that sodium-ion batteries could reach pack densities of nearly 150 watt-hours per kilogram by 2025. And some battery giants and automakers in China think the technology is already good enough for prime time. 1

    +1 for them not exploding too.

        because it has the potential to be sustainable, cheaper, and less explosive. It’s not technically superior as far as energy density goes, but right now batteries are prohibitive in many applications, moreso due to cost than weight.

    I won’t be buying a new car. ICE or EV. Specifically because my old car doesn’t have a lot of the things that allow the car manufacturer to spy on me, and I won’t upgrade to any of the nonsense. Right now I can fix pretty much everything in that car for less than the price of a new vehicle.

    Obsession with one of the least energy efficient and one of the most harmful ways of transportation has to end.

    Build a fucking train.

    gasoline cars and motorcycles will be missed, like analog film cameras and quarter inch reel tape. people will imagine what it must have been like when cars were bad ass.
