China's 'Artificial Sun' Breaks Nuclear Fusion Limit Thought to Be Impossible (the-independent.com) 32

"Scientists in China have made a breakthrough with fusion energy that could finally overcome one of the most stubborn barriers to realising the next-generation energy source," reports the Independent: A team from the Chinese Academy of Sciences (CAS) said its experimental nuclear reactor, dubbed the 'artificial Sun', achieved a plasma density that was previously thought impossible... Through a new process called plasma-wall self organisation, the CAS researchers were able to keep the plasma stable at unprecedented density levels. By pushing plasma density well past long-standing empirical limits, the researchers said fusion ignition can be achieved with far higher energy outputs. "The findings suggest a practical and scalable pathway for extending density limits in tokamaks and next-generation burning plasma fusion devices," said Professor Ping Zhu from Huazhong University of Science and Technology, who so-led the research.

Professor Zhu's team now plan to apply this new method on the EAST reactor to confirm that it will work under high-performance plasma conditions. The latest breakthrough was detailed in the journal Science Advances in a study titled 'Accessing the density-free regime with ECRH-assisted ohmic start-up on EAST'.

      Hey. That guy is going to run Venezuela, okay. And he's super busy frog-walking its former dictator and doing armed pursuit of heavy crude oil -- that no one really wants because (a) oil is $60/barrel, (b) it's too heavy to easily refine and (c) the country he's extorting is too politically unstable and lacks sufficient infrastructure for more investment and production. Sure he says Venezuela will "turn over" 50 million barrels (which is only two months of U.S. production), but that will be sold and the proceeds put into commercial banks (no, not the Treasury) for this guy to personally control. Also he got to finish building a ballroom and put his name on a few more buildings... You know, what his people voted for. So he's way too busy grifting, grafting, raping (*cough*) and pillaging to also run China. Geesh. /s

    My memory may deceive me, but this could be one of the rare tripple-stories on Slashdot!

    Because of this announcement, researchers say that practical fusion energy is - what - only 10 to 15 years away? /s

    • I dream of the day when a news story about fusion won't be accompanied by this same old tired attempt at humor. It remains only a dream.

      • It's good to hold onto your dreams - no matter how unrealistic!

      • I dream of the day when a news story about fusion won't be accompanied by this same old tired attempt at humor. It remains only a dream.

        After 50+ years of every breakthrough reported being followed by "unlimited fusion energy is just 15 to 20 years away" it's kinda hard to not make a joke of it. Duke Nukem Forever was delayed by 14 years and was a similar joke. The promise for fusion being 20 years away has gone through 3 generations now.

        • The main problem with the "fusion industry" is not the difficulty to have a few reactors doing proper fusion ...
          But: there is no industry.

          Supposed you wanted to replace all the remaining coal plants with fusion ... you need to build a plant. You need the fuel. You need to transport the fuel ... and so on.

          When fusion is ready, the planet will not need it anymore. But we can dream of space ships, right? And bases on outer worlds ...

        • "Duke Nukem Forever was delayed by 14 years"

          Seems like this is becoming the norm.

      • So you are upset that a long-running meme about how vaporware continues to be vaporware, is still a long-running meme on any story related to the quintessential example of vaporware?

        Reminder: even with this place being a shadow of former glory, you aren't the only one reading. Its fine to not comment.

      • But I would have been disappointed if it had not appearedâ¦.

    • It's not a certain number of years away, it's a certain number of dollars away. This is a solvable engineering problem. Fund it, and they can get it done.

      Sadly, I think if anyone is going to do it, it will probably be a Chinese team. They have the funding and seem to be making rapid progress in a number of fields, while we are busy with other stuff.

      Fusion energy is still an unknown number of years away - and the proof that it is economically feasible is even further. However, this type of advancement gets us closer to running a reactor in a domain where we can at least start working on the considerable materials challenges that need resolving.

    Who knew that replacing gravity as a means to contain a stable continuous nuclear fusion reaction would be such a challenge?
    Heh....

    • It's not a fusion reactor so let's cut the hype headlines.

      People are so desperate for "clicks" nowadays that every science news is a "breakthrough" or "revolution" now, especially in fusion, superconductivity or quantum computers - however reaching this "new density in plasma confinement" is still interesting.

Why do we want intelligent terminals when there are so many stupid users?
