    You know what would be useful in a societal collapse? Electric vehicles and solar panels.

    Hopefully peppers aren’t building zombie busses because they’ll be useless in 6 months after the oil stops flowing.

    An ev with a charger panel and bicycles will be useful indefinitely.

      When society collapses, upwards of around 95-100% of us die. That’s reality.

      Solar panels and batteries require massive supply chains. They require our rarest minerals and highest tech, with highly educated workers to develop and produce and state of the art clean rooms and factories.

      If we stop producing them, the current stock will be useful for like 50 years tops. Then it’s back to fossil fuels, I’m afraid. Diesel generators last for a long time, and they’re easier to maintain and produce.

      I remember i read a doomer theory stating we should be stockpiling coal for the humans that remain to rebuild society since there is nothing we can do at this point and fossil fuels is the only thing that will outlast the collapse. I’m not that pessimistic, but i can see what they mean.

        Lol, Diesel can on average only be stored for 6 to 12 months before degrading. Good luck with that.

        If a collapse ever happens I’d rather have solar panels and an EV. Fuel production and transport would instantly grind to a halt and the existing fuel goes bad soon after.

          Yeah, it’s true diesel degrades quickly, but oil does not. Depending on where you live, you could more quickly set up a low scale refinery than a solar panel manufacturing workshop. Most likely, people would use coal in most places without access to oil in short distance since it’s more widely available and simpler to use.

            Mate, we are talking about a societal collapse. You won’t have oil available and you won’t be able to refine your own diesel at home (especially without energy).

            Your argument about solar panels being difficult to produce is utterly out of place. Your diesel generator and your car are more difficult to produce, but you already own them from before the downfall. So if you own an EV and you own solar panels then it doesn’t matter how difficult those are to produce when you’re just using them.

              I wasn’t talking about making diesel at home. That’s pretty much the immediate aftermath of a collapse.

              In the case of a societal collapse, eventually, new city states will be formed using salvaged technology and eventually technology produced of their own. My argument stands that to restart civilization, you will more quickly go back to fossil fuels, which are simpler to salvage, manufacture and utilize than high tech solar panels and batteries.

              This includes gas vehicles. It’s just a fact that electric vehicles and semiconductor technology are luxuries of the modern era and not long term post apocalyptic tools of survival due to their manufacturing difficulties, durability and maintenance necessities. Just as an example you have Toyotas from the 60s that can still work just fine and i guarantee you a Tesla made today won’t work in 60 years, unless you replace nearly every electronic component of which it depends.

              I’m all for renewables and sustainability and ditching fossel fuels, but from an engineering point of view, i just don’t think I’d be trusting in electrical vehicles and semiconductor tech in a post apocalyptic scenario. The reliability just isn’t there.

              And diesel generators/fuel refining is most definitely not more difficult to manufacture than semiconductors. Just to make a simple silicon wafer you need more tech than to make a piston engine. Let alone doping it to produce enough photoelectric effect to power stuff with. There’s a reason we more quickly figured out diesel/gasoline engines than semiconductors. You need clean rooms, high tech engineers and a lot of robotics for things we can’t do with enough precision with our big clunky hands at the nano scale. With piston engines a workshop will do and fuel refining is just basic fractional distillation. As a side note, i could most definitely refine diesel at home. I’ve distilled things more complicated than diesel. But that’s beside the point. I understand you meant the average person with no training wouldn’t be able to do it and i understand and agree.

            Gas only lasts like 6 months before expiring. It can be stabilized to last a couple of years, but within 3-5 years all existing gas would be unusable (as far as I understand it).

            Running a solar system past its ideal life when it holds even 20% of a charge and has lower efficiency is better than nothing.

        The doomer theory variation I read is that we’ve played out most of the accessible fossil fuels. If society has to rebuild, they have no way to get past the stage of fossil fuel use, because advanced extraction like fracking would not be possible. The very things that made our society possible, are bridges were burning as soon as we cross them. There is no rebuilding

      you would get murdered for those rather quickly, i’d imagine. what would be useful is to get far away from strangers somewhere defendable near fresh water.

        That would be only one of the many competing reasons for my murder.

        I do have camping gear, woodworking hand tools, a good bike, I know how to shoot and clean fish+game and cook, and I have knowledge of some remote areas with sparse populations including their flora.

        On paper it all sounds good, but I would likely die miserably in the first Canadian winter.

          Even if you did everything right there isn’t that much wildlife to live off of. A single human requires a vast healthy wilderness to live off of foraging only.

            Yeah, I watch Alone and I’ve seen Outlast. No way are 99% of people going to be able to live like that. Even the contestants who prep and practice and research only last a few weeks in the winter.

            You would need a small community, agriculture and to store your food for winter, and livestock for reliable protein. Even then there’s a good chance you get wiped out by diseases unless you’re making soap and prepping food and water safely.

              But once you’ve figured out a way to store food and resources, then you’re a target. You can’t easily defend against bands of looters with tons of weapons and nothing to lose

        Maybe. I’ve wondered about that. It’s easy to imagine a Mad Max scenario with bands of raiders looting all potentially useful technological remains, but does solar change that? You can’t as easily steal that without destroying it. You can’t just put it to use without some technical knowledge. It’s not immediately useful to loot.

        Destroy, sure.

      Don’t worry, we’ll fix climate change by reflecting sunlight before it hits the Earth’s surface. Of course this will eradicate most pests (and nature) but hey, problem solved!
