    Humans produce CO2.

    The difference is whether you produce CO2 flying private jets or relieving famine.

    Also, you would have to spend energy to go the other way, as CO2 has lower energy than protein.

        EDIT: I see you have redacted this take. That being said,

        This is being produced from fossil fuel & steel production waste gases, so it’s a way to eliminate emissions by trapping them with specially engineered microbes. Reading about the pathways they’re using is actually really cool.

        We’re not getting rid of steel production any time soon, so turning emissions into ethanol (rather than using agricultural products) seems great.

        In general I am skeptical of “greening” fossil fuels but the opportunities to make them less harmful present themselves immediately when you look at all the redundant burning and shit involved.

        Substituting green sources for the energy intensive fractional distillation process & the hydrogen feedstock in making gasoline could be easier if the overall production of fuels were much lower. (Renewables + continuously chugging fractional distillation seems like a bad mix but batteries are getting way better all the time.)

        I read about some of this stuff & how oil refineries work first when I was arguing with “genes aren’t real” and “oil is renewable” patsoc people actually. Lol

          Interesting. It would be liberalism to think that innovations like this could fix our environmental crises without a revolutionary transformation of the relationship of humans and non-human nature, but considering this is largely an accomplishment of socialism, and China has greater plans than small changes, this is good. Patsocs always have weird anti-science takes, but those are new to me.

            I can give you a long list of battery tech & hydrogen stuff & renewables especially coming out of China that makes me hopeful, as well as ecological civilization shit that doubles as climate resistance like sponge cities that Malaysia’s getting into. and also some example of stuff i’m not big on we’re doing like the 70s era carbon sequestrarion US/EU keep pushing and the like coal to hydrogen lmao

              I did a whole project on this last year, but I’m sure there’s more new stuff that you’re more up to date on than me.

                Maybe. Idk if I mentioned the new desalination stuff that looks promising. Other random stuff

                cold plasma pyrolysis of trash -> syngas (i’ve read this can be quite efficient correct me if i’m wrong)

                sodium ion batteries (appliances and other applications where density is less important, there are already power drills)

                redox flow batteries (very long term storage with many cycles perfect for renewable power stations & datacenters, made from cheap shit, can completely replace large lithium bricks)

                zinc solution hydrogen batteries (80% efficiency vs 50% of compressed hydrogen gas, zero fire hazard)

                floating wave generators for supplying outlying islands nations throughout the pacific

                  I was keeping up through dongsheng news, but then I deleted Telegram, so I’m not up to date with tech. Thanks for all this, very optimism inducing.

                  new desalination stuff

                  That’s cool asf. Hopefully developments like these will help Mos Def’s observations cease to be true. My one concern is what happens to all the salt. I’ve heard that over-salination can be damaging to ecosystems. Might there be a coming innovation that will allow the production of table salt in addition in this efficient way or something?

                  cold plasma pyrolysis of trash -> syngas

                  I think I heard about something like this in like 2018 and have fantasized about it since. I think what I heard was that the Netherlands used it and it was too good or something? I’m glad there have been advancements in it.

                  sodium ion batteries

                  redox flow batteries

                  zinc solution hydrogen batteries

                  I’m happy about any tech innovation that means less rare mineral extraction is necessary.

                  floating wave generators

                  I’m glad there’s progress on those.

                oh also on the lithium ion front, there’s a cellulose mesh being messed around with that triples the number of recharges you get. and lithium-sulfur is actually feasible now

          Regardless of the initial hot take, upon further looks this is a positive development assuming it helps promote future developments and not just fossil meat as the title suggests.

            Tbf, my instinct with things like this is to assume that it’s more greenwashing or similar. They’ve tried to have us on too many times before for me to be very trusting.
