    To the best of my knowledge, this is the first commercially-funded (i.e., non-government) nuclear fusion reactor. Notable investors are MiHoYo (developers of Genshin Impact), Nio (Chinese EV company), and Sequoia Capital…

      In your guys opinion, is that good or bad? Privately funded would mean proprietary & profit driven implementation for such a crucial technology (if successful). I personally don’t like it.

      No??

      I’ve supported engineering at several privately funded nuclear fusion companies, though all of them, this Chinese company included, are building a product out of public school research.

      Off the top of my head there’s:

      • CFS
      • TAE technologies
      • Thea
      • Zap Energy

      And several more…

        Building, or built? Either way, maybe these companies will come out with a better design than Tokamak, but until then they’re literally just research ventures because the vast majority of investment at actually scaling fusion is happening for Tokamak tractors.

          Built, physically operational reactors that operate as close to Q=1 as they can, with all the diagnostics included.

          The diagnostics are very important, as plasma instabilities have been, and continue to be, the critical issue preventing anything useful coming out of our decades of fusion reactor design. All these companies are sharing data on overcoming plasma instability issues, with multiple geometries aimed at evaluating how plasma responds to different inputs in different environments. We’re all trying to understand how to control and compress something far too hot to physically touch.

          @naturalgasbad@lemmy.ca scaling fusion isn’t a trivial problem, and saying it like it is indicates a lack of background knowledge. This isn’t a competition between companies (no matter what our CEOs suggest), as we in industry quietly all agree that any of us that cracks this unchains humanity from the solar system. Because government funding has unfortunately sucked so much ass, we’re sort of using private money to get the basic research done. We’d be so much farther ahead otherwise.

    In the image of the discharge you can clearly see that the device has no cladding. That means a discharge would be limited to a duration of a few seconds, otherwise the material ablated from the wall would lead to extreme heat losses of the plasma. Did they include a future vessel cladding to the plasma volume calculation in the article?

    Maybe at some point the Americans will get scared that the Chinese are actually making strides ahead of them in electrification and decarbonization to actually get unstuck from their idiotic culture war over fossil fuels.

        The space race is on. That’s why Starship has been launching so much. Someone at the FAA must have finally realized that if SpaceX doesn’t go ahead at full SpaceX speed, we’re gonna see China take over space.

        They’ve got a space station and a rover on the moon. China will easily overtake us in space, has already in a few places.

          And by “take over” you mean uselessly posture and dick waggle and colonialize in brand new space accords breaking ways.

            Oh yes, this is a competition, and someone is going to win it.

            There are lots of resources out there. Far more than here. Most of “the world” is out there. This is happening whether we like it or not.

            And all the “dick waggling” is steps on the path to it happening. Funny flesh images, homoerotic shaming, whatever this dick talk is about whenever space comes up, none of it changes the serious nature of what’s going on in space.

            True. China is making rapid gains in territory and influence on Earth and Luna, and soon plans to expand its operations into the Belt.

      Oh, Amerikans would sooner nuke themselves than even consider uncoupling themselves from fossil fuel. All Amerikans care about is “profit uber alles”; they’d rather choke to death on smog and fracking run-off than ever admit Chinese STEM is beating theirs by every conceivable metric.

          The fuck kind of kneejerk is that?

          Show me mainstream chinese media that openly criticise the government and Xi. Then you can talk. Until then, accept that chinese media requires a few truckloads of salt.

            Are you old enough to remember how every single mainstream journalist promoted the Iraq war? (no, “maybe the war could be executed more competently” is still supporting the war) How about Libya?

            Isn’t it funny how the mainstream media just happens to align with the state department every on every single issue?

              Old enough to remember there were lots opposing it as well. Just.like the current Gaza war. Just like they have criticised immigration policies, or approved them. Same with coal, same with the EPA neutering, same with the oil spills in the gulf. Same with the lack of proper aid and support when the lowlands flooded.

              Just because you ignore it, doesn’t mean it doesn’t exist.

              I’d be happy to adjust my opinion, should you provide similar journalism from china, about china.

                Old enough to remember there were lots opposing it as well. Just.like the current Gaza war.

                Except none of them meaningfully oppose the gaza war. The closest thing to criticism you’ll hear from a mainstream source is how Netanyahu personally isn’t carrying out the war out humanely enough. Note that this is not actually opposition to the war, since it just calls for a return to the state of slow ethnic cleansing that spawned the war. They oppose the way and rate the settler colonialist ethnostate carries out ethnic cleansing, not the settler colonialist ethnostate whose national project requires ethnic cleansing.

                Just as in the Iraq war, nobody was saying “This is bad, and we should leave now, there’s a million people protesting it outside” until like 2006, when the plans to leave were already drawn up (a schedule Obama maintained).

                There was a million “The war is good, but it’s being done poorly” and later on “The war is bad, but we’re here and have to carry it out more competently”, but the idea of not pursuing the war was so toxic, republicans would accuse democrats of wanting to “cut and run”.

        Poor people also care about not dying from the effects of climate change.

        Poor people don’t care about the megaprofits of the oil, gas, and automotive industries.

          That site is garbage. The atomic unit of propaganda is not lies, it’s emphasis. NYT (and most western news media have supported every single military action the US has done when it mattered.

          This isn’t reflected in their ratings, since they don’t need to use lies to get people believing wild misconceptions. It is reflected in the way the American people are mobilized to support each military action.

            That site gets used for academic analysis of media bias and has been shown to agree near perfectly with other third party media bias ratings. It would be nice to have a “nationalist” bias ratings as well included but I suspect it would be an unbelievable amount of work and nearly impossible to make balanced beyond their press freedom ranking and overall bias reports. And it’s not agonizingly difficult to read primary news sources and competing perspectives while sticking to sources that have a reputation they care about protecting regarding vetting sources and publishing reasonably accurate news.

            You however seem to be suggesting that media honesty is hopeless anyways so you may as well take blatant propaganda “news” sources with poor fact check ratings, from nations with deplorable press freedom as equal to any other. Which is an incredibly dangerous and frankly idiotic perspective to have.

            The NYT is obviously biased towards western interests in key ways, the BBC and NPR are even government funded news agencies. They are not in any way equivalent to RT or SCMP let alone the Global Times. There is a level of press freedom, academic freedom, transparency, and freedom to criticize that is completely incomparable.

            TLDR: Fuck off tankies, authoritarianism is not welcome in lefty circles as long as I have something to say about it.
