    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.

      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

      The title says “1000 miles”, the the subtitle right below says “moving closer to 1000 kilometers” which is only 621 miles and pretty close to what we already could do with a ridiculously big battery in a Lucid Air or Tesla (if they didn’t bother with the plaid speed bullshit and just build for single motor range).

      Stupid editorial work for maximum click bait.

    That would go a long way towards solving the range anxiety barrier. 1000km is close to the maximum that same people can do in a single day. Yes, you could push further in a day in a pinch, but not comfortably unless you’re rotating drivers. It’s pretty close to the limits enforced on long haul truck drivers in Canada or the US (depends on speed limits and traffic density and a few other things).

          After driving non-stop for 200+ miles I’m more than happy to take a break for 15-30 minutes to stretch my legs, hit the bathroom, grab some food, etc. My wife and I have done precisely this on multiple road trips that we’ve taken in our EV.

        It’s not 1000km. You lose 30-40% range in the cold. And charging cadence is typically 10-80%, not 0-100%, so you lose another 30% on road trips. Now your 1000km EV does 420-490km between chargers. That’s around three hours on the Autobahn at a rather leisurely 150kph, with a 25-40 min stop. I agree with the user above. Affordable 1000km range is minimum before I’ll be buying another EV.

    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

        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.

      I’ve managed to somehow make friends with the owner of a local junkyard. Not quite sure how I did that it wasn’t intentional but it’s quite useful because I can get parts for my car that the manufacturer would want hundreds of pounds for otherwise.

      In the future I bet they pull some apple style rubbish and start software locking components to individual vehicles so you can’t just pull them off a donor car to fix yours

          Seems unlikely. For one because donor parts like computers would have to be programmed (either by the manufacturer, or a mechanic with access to a scan tool that could do so), and so if you need a new ECU you’re limited to those options or a third party service that will clone that computer. And two, most of the things I’d need to replace on that car that aren’t computer related are easy to get second hand from a pick n pull, junk yard, or aftermarket and don’t really have the kinds of electronics used to send and receive info to a car manufacturers servers. I’m not worried that my MAP sensor is gonna spy on me to BMW. I would worry if it were an ECU or a TCM or the like. The other thing is it would require upgrading the 3G chip in a lot of cars on the road to 4G or similar and or plugging a 4G device into the car somewhere like the OBD port which would be quite obvious in my car.

        I don’t think there’s any need to be snide about this comment. A 2015 Honda Civic is objectively superior in almost every way to a 1967 Corvette, but the 'vette is inherently cooler in a way that the Civic will never be. It’s just nostalgia for a bygone era, that’s all.

          What is “cool”? Subjective right?

          If you have a passion for driving, and enjoy the ride feel off a 67 Corvette, as a pie chart, the 'vette is vastly superior because both cars are tools. The same tool can be used for different situations but its the situation that defines what is superior and what isnt.

          Its just a matter of perspective.

          I say this as someone who prefers driving a stick shift. Ive probably driven equal kilometers on automatic vs stick.

          While i very much would like one, EVs are probably just as distinct in their own way.

          I would place a very large bet that some people feel the same way i do about standard transmissions as they do about EVs. And there have already been articles about there being a learning curve when switching to an EV

    The problem is we can’t keep the same resources waste up. Lower range and smaller cars is what is needed. The perfect car of the future would be a one-seater that is as small and light as a electric velomobile (~70kg). Build a few millions of them and replace all cars in a city with those. Ideally self driving and as a robo-taxi, but even without the self driving this would be good. Of course cars isn’t really that high on the list for climate change.

    But as a civilization we are simply not an intelligent species.

        Yeah it’s not a solution to everything. I imagine the standard “super light” robo taxi as a two seater with the seats facing each other. Without a driver seat you can redesign individual transport to be narrower which improves aerodynamics.

        But yeah for families or cargo transport you still need larger vehicles. Or take two. And I also imagine this to be more of a “gap filler” besides public transport or bicycles. It would really require a pretty big redesign of how we live and work to reduce our energy and resource usage to zero.

      I’d love gel and lithium-ion batteries in an ebike or a velomobile. It would result in a 40% increase in range with no extra weight, making them more of a viable alternative for somewhat longer commutes (think 10-15 miles). Sure we should be serving those by high speed public transit, but this would be a faster stopgap/alternative.

      Oh and it would be useful for electric trucks too, even short-range ones could be made lighter with less batteries.

      Actually surprised how little cars actually contribute to climate change I thought it was a major factor but they’re not really. If everyone in the world just switched to using LED light bulbs rather than incandescent it would be equivalent to removing half of the world’s cars from the road. And honestly seems easier to upgrade everyone’s light bulbs to LED than to replace every car.

        Directly via exhaust? It’s a significant number, but maybe not the biggest one. But add manufacturing, oil (or battery materials) extraction and refining, road infra construction and maintenance, emissions connected to suburbanization, microplastic pollution from tires, health and safety impact, and you’ll get a much grimmer picture. LEDs won’t cut it, and cars do not scale to 8B people.

        3000 miles is not something we as a society should accommodate to travel by car. The whole problem is that everyone thinks we can keep doing the same lifestyle just with zero carbon. We simply can’t. We need to change how we live and work.
