    Well, no, not really. What you're seeing here is a news-friendly interpretation of science, which results in it being mostly bs. They have no sustained fusion and no reliable containment. As of this point, China's the only one who's managed a sustained fusion.

    Can you post a link to support Janson's claim?

    China Takes One Small Step Towards Fusion Power - China Digital Times (CDT)

    When plasma is magnetically confined and heated beyond a certain limit, it transitions to a high-confinement mode, or H-mode. In this mode, the plasma itself spontaneously generates an “edge” that partly prevents particles from escaping, and it throttles turbulence in the hot material. This more than doubles the time plasma can be confined. The present study achieved more than 30 seconds of a sustained H-mode pulse, an improvement of 10 to 20 times beyond anything achieved at other reactors. Thirty seconds may not sound like much until you realize this is plasma at more than 100 million degrees, more than five times the core temperature of the Sun.

    Note US contribution :)

    US contribution? ITER yes, and in the future....

    But, we are talking about EAST now.

    " the latest run at EAST achieved a plasma pulse lasting over 30 seconds, a record achievement that simultaneously demonstrated improvements in heat dispersal."
