      Sure, and then what? If we keep the systems around that created this situation in the first place, we’ll end up back where we started, just with new rich people.

      Just to pick out the example of veganism: If all rich people are dead, but the masses still want cheap meat every single day, they WILL definitely reinvent factory farming, with all it’s horrible environmental and ethical consequences.

      It’s more a problem of all the human people want to live good lives, look at how many threads on the front page are talking about cost of living crisis and etc as serious social problems which need to be fixed - there’s a thread where everyone says we should all be in walking distance to all key amenities, I bet they all think that the average persons wage should be able to afford to enjoy those things regularly too and have access to healthy fresh food, good clothes, etc etc

      The world people want where everyone has access to a good life has never existed, even in America there is still generational and regional poverty but globally it’s much more intense - it would be very unfair to say ‘sorry we’re not going to try and continue progress so you can live the same life I do, we’re actually going back so you get less and work harder - it’s not because further progress is impossible or anything but I personally don’t really like new technology so, well, sucks to be you I guess.’

      The technology which you’re talking about carbon capture is an incredibly good technology and just because you don’t understand it doesn’t mean it shouldn’t exist. It’s not a magic wand of course but no one said it is, the uses with SAF and bioavailable carbon for example open up a lot of possibilities not just in rich nations but actually more so in developing nations allowing growth without oil infrastructure.

        The problem with carbon capture is it’s not pulling anywhere near the amount of carbon from the air as needed and it’s currently very expensive. And it’s an easy out for politicians. A lot of the plans seem to be “we’ll do the easy stuff to reduce CO2 emissions, so how much more is the net emissions come to? Ok then we will do that much carbon capture… someday… somehow…”

        And a good amount of it is pumping CO2 into oil wells… to extract more oil.

        We really don’t know how well carbon capture will work on the large scales needed to balance the books on the “easy mode” net zero policies. Given how expensive it is, is it the most economically viable solution?

        Sure the cost may decrease… but by how much?

        A lot of question marks with it in terms of economic viability.

        I do think it’s needed but I’d prefer it being something that’s just used for fuel that’s extremely difficult to replace, like fuel for airplanes. It seems feasible to tack on a big enough carbon tax on jet fuel to cover the cost of the carbon capture of that fuel. Sure airline travel will get more expensive, but that should be fine. But the level of carbon tax needed to cover the costs for ground transport using fossil fuels seems like it would be prohibitive.

          It’s solved if your government gets off its ass about it. Reprocessing waste for reactors is one of the few places where nuclear makes sense. Way better than burying it for thousands of years.

          Otherwise, the economics have ran past it. We have solutions without it; we just need to scale the up. There are a few other niches, like cargo ships, where they make sense. For general power use, no.

        TBH, nuclear waste is a political problem, not an engineering one. Finns figured it out, no reason other countries couldn’t.

        Fusion of course is better (though some small amount of radioactive waste will still be produced due to neutron activation of the materials used in the equipment), but it seems like it’s been 10 years away for the past 60 years. And we really shouldn’t let perfect be the enemy of good—we need to phase out fossil fuels yesterday and fission is good enough for answering the needs of the industry; solar and wind is good enough for distributed residential power and also a good choice for poorer countries who lack the knowhow or even stability for safe operation of nuclear.

            I’d like to see effort put into restoring the land back to how it was before our initial interventions. But I do think after that’s done, leaving it alone to allow wild animals to repopulate the area is probably right. That land was doing just fine before we came along.

            Also, many people are vegans because of animal ethics or because it’s trendy, but aren’t really thinking about larger issues.

            Most vegans would say they’re doing it for animal rights, yes. This doesn’t preclude vegans from caring about the other good reasons for going plant-based. At very least, carrying animal rights further, it makes sense that it would help animal welfare to repair some of the damage we’ve done.

            One of the most visible vegans I know of talks about this so it’s definitely on vegan’s minds.

        No, flywheel is not cheap enough and too complicated. Pumped hydro is cheapest, but only available at very few location. Lithium batteries are a waste or misappropriation (lithium should be recycled for mobile use) and there aren’t enough.

        The two battery types that seem to work are liquid metal batteries that are made out of dirt cheap and abundant materials (although there might be problems there still), and flow batteries. Kite power also seems to provide more energy for less material costs (no huge foundations and towers needed).

          There are also gravity batteries: https://www.euronews.com/green/2024/02/06/this-disused-mine-in-finland-is-being-turned-into-a-gravity-battery-to-store-renewable-ene

          The gravity energy system would be able to store 2MW of power and integrate into the local energy grid. … Scientists from the International Institute for Applied Systems Analysis (IIASA) found that the world’s abandoned mine shafts could store up to 70TWh of power - roughly the equivalent of global daily electricity consumption.

          Also in Finland, but different technology “sand batteries” https://www.bbc.com/news/science-environment-61996520

          Finnish researchers have installed the world’s first fully working “sand battery” which can store green power for months at a time.

          The developers say this could solve the problem of year-round supply, a major issue for green energy.

          Using low-grade sand, the device is charged up with heat made from cheap electricity from solar or wind. The sand stores the heat at around 500C, which can then warm homes in winter when energy is more expensive.

          While I think there is still no working production model, Iron Salt Batteries are very promising https://en.wikipedia.org/wiki/Iron_redox_flow_battery

          There are different options, not each one is suitable for every place, but seams possible that combination can help us achieve needed reduction in fossil fuel usage when sun is down and no wind.

            Thanks for the links, sand sounds interesting. I believe gravity batteries outside of pumped hydro just need too much “structure” to store energy and then just have too little capacity. Unfortunately there is sometimes a little bit too much hype about cool ideas that don’t pan out. There is also an idea I think for an electric train / rail cars full of ballast being driven up a rail on a hill and then moving down to release electricity. Just a lot of effort.

            And yeah thermal batteries should solve one of the biggest consumers, heating. Lots of possibilities. Molten salt works also. I think if you just use water to store heat for the winter you need about the size of a big Olympic swimming pool under your house. But with wind instead of solar you don’t even need to store that much.

            An important thing I believe is that we have nearly unlimited access to energy with solar and wind turbines / kite power. It requires massive production efforts but you can extract so much energy from sunshine that efficiencies of batteries aren’t even that important. Just that you can use cheap and sustainable materials, can recycle them, and can have enough energy density.

            So the possibilities are definitely there, but we really neglected to push R&D and massively fund multiple startups for each technology. And we need to suspend patents or drastically shorten their lifespan to like 4 years or so.

          It’s not necessarily the meaty “taste”. Many people have health complications with their digestive systems (one example I can think of is Celiac’s) that can make it near-impossible to get nutrients from plant-based food. If you can grow meat in the lab, you can get animal-sourced nutrients without hurting animals (for vegans) nor large resources that are typically used for climate-damaging meat industries (for everyone)

      Meat used to taste delicious.

      I was raised pescatarian and started eating a little bit of meat in university, it was pretty good. I could definitely understand the hype, meat was pretty delicious. But for me personally, I just don’t get the craving for it. Eventually I just ended up going back to a near vegan diet because it’s what I like to cook, and it’s so cheap. I’m not vegan, but 99% of what I’ve cooked at home in the last 10 years is.

      However, I was craving charcoal chicken for like two weeks straight, so the other day my friends and I rode down to the place everyone goes to. We made a proper day of it with our bikes and picnic blankets. The chicken was cooked perfectly, really moist and falling off the bone. The seasoning on the skin was delicious, I can see why that place is so popular.

      But the chicken had no flavour of its own.

      Taste wise, it could have been anything cooked with the seasoning rub over the charcoal spit. A block of tofu would have had the same flavour.

      Texture is the only unique experience, and I’m sure there will be a brand of meat replacement out there that has nailed the texture (but not nailed the taste) so it really isn’t long now until there are viable alternatives. I haven’t really tried many meat replacement products because I’m allergic to potato and e160c and those two ingredients are in a surprising number of vegan packaged proteins.

      I was disappointed with my chicken. I thought maybe I’d over sold it in my mind, as my friends confirmed that yup, this is good chicken, I’m being picky. But when I said “it’s just not as good as I remember from uni” and then my friends did a full 180° and agreed that yes, in the last 10 years since I’ve had chicken like this, meat quality has gone downhill, and chicken isn’t good anymore, but what we were eating was good chicken, and that they all still like chicken, even though it’s disgusting by direct comparison.

      Now I’m curious how different the quality is between home raised chickens vs store bought chicken meat. Because it’s got to be insane, even if both birds are the same species of heart attacks on legs.

        My brother raised chickens and we went to his place for a dinner with one of the chickens he raised. It was probably the best chicken I have ever had. The store chicken barely holds a candle.

        Now this was probably over 10 years ago, and I know the farm chickens have “improved” but the improvements are more… for production. Not for quality and taste.
