    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
