    So you’ve heard about fusion before, but it was a while ago, maybe even years ago and now you’d like an update about where the research is at. Are we any closer to commercialization? That’s the good news: you don’t need an update because of the “fusion constant”.

    If asked, how close we are, scientists have given roughly the same answer for generations. Fusion never gets any closer. The answer is always “about 40 years”. And that’s been the case for about 70 years.

    Probably unsolvable problems in principle include: plasma contamination from interaction with the first wall, plasma control and turbulence (magnetohydrodynamics are even harder than the famously unsolved Navier-Stokes equation), finding a reason why to even do it (renewables and batteries get better and cheaper every day, fusion will never be cheap and able to compete).

      Yeah, that’s basically what I had understood to the the case, I guess my real question is - is there anything unusual about this new Chinese project? Or is it just more of the same?

        They have achieved over a minute of sustained firing now. I personally, highly doubt that the problems are unsolvable, it’s just a matter of doing sustained investment in the tech which hasn’t really been done at this scale before. Meanwhile, the solution to plasma control problem is AI, Chinese team successfully developed a system that can do early detection of disruptions.
