The US National Ignition Facility has achieved even higher energy yields since breaking even for the first time in 2022, but a practical fusion reactor is still a long way off

        I mean … the article is literally what it’s about.

        You’re being downvoted because you’re being a cynical contrarian.

            Saying nothing will ever work ever and nothing is ever good is not being skeptical.

            The article you’re commenting on is the citation, you’re being cynical and acting in bad faith.

            People disagree with you, I’d wager if you used a little more tact you might have more reasonable discussion.

                This reads kind of like Derrida, or JB Peterson, where it almost seems like the goal is to deliberately avoid communicating in a way that is clear. To paraphrase, “You all misinterpret what I say, not because I’m bad at communication but because you all are.” If one person misunderstands or misinterprets, maybe that’s on them. If everyone does, it’s more likely that it’s on you.

                    No wonder people think fission is a sure thing.

                    This article is about fusion, not fission.

                Not in our lifetime, nor the lifetime of our children or grandchildren. And it is almost a certainty not to be ever in the lifetime of man.

                Sure sounds like never.

                    Ah right, you left open the possibility that maybe in a billion years it might work. You sure got us. Fuck off.

                Why will a tokamak never work, exactly? We’ve been running fusion experiments in them for 60 years and have a pretty good idea that we can make one big enough to produce power. We’re just baby stepping through the work so we don’t build a $30 billion dollar power plant that’s missing a design element.

                K-DEMO, JT-60, DEMO, CFETR, STEP, and the US DoE’s planned reactor suggest a high level of confidence that the science is already there. It’s just an engineering problem, much like the nuclear bomb in 1935.

                    Oh ye master of nuclear material engineering, please share what you know so that multiple countries with teams of experts don’t spend billions of dollars for a complete failure. (I worked for an ITER subcontractor numbnuts)

        That’s because your comment is on a post that is literally one of the sources you’d get. More efficiency, overcoming total input, making it a generator, etc are all ancillary.

      I mean, it’s what the whole article is about. If you mean successfully generating sustainable electricity from fusion then yeah, maybe. Maybe not. People said flight was impossible too, you never know.

        We’ve harnessed the power of fusion in nuclear weapons for decades already.

        We’ve literally put it in a small container.

      The technology exists. There’s huge funding going into it recently. Europe’s ITER project is working towards it also, but in a different way.

      The only major issue faced right now is how to increase the efficiency.
