    Nothing makes me as skeptic as this subject, but the source of this news deserves some consideration.

    Time will tell if it is vaporware, such as cold fusion turned out to be. Now we wait.

    From what I gather, it's definitely not vaporware... but it's also extremely far from achieving a sustained reaction. And still, the results so far look promising enough for at least continuing this venue of research.

    There have been several recent incremental developments in generating a fusion reaction with different techniques.
    The big if, of course, is can any of them be scaled up to give an economical, practical source of fusion energy. :confused:

    The laugh comes in the last paragraph, where they properly admit:

    "Zhang’s team acknowledges that there is a very long way to go before they can realistically consider using a device based on FuZE as a fusion generator."​

    But then the author pulls a rabbit out of a hat and pronounces:

    "... initial results show for the first time that devices that enable sustained nuclear fusion need not take up huge amounts of space."
    Oh really, and you concluded that how?

    Like I said,we wait, you can bet many qualified people will duplicate and try to improve on these results. If it has any real promise we will see a slow but steady incremental improvement in performance, or perhaps, a real breakthrough, but it will take time either way...

    At best they just proved the sheared-flow stabilized Z pinch theory to be correct but Z pinch at the table top size can't provide sustainable fusion reactions for a Q (fusion energy gain factor) equal to or greater than 1.

    This might.

    You guys need high frequency to control and coral plasma.....not high power. One frequency comb for the negative and another comb for the positive.

    You should be able to square dance.

    This is why the world needs to save it's coral reefs.

    You've given away the secret to fusion in 5 years.

    It's a fake cover, check the date.

    I assumed that was the point. Fusion was still just 5 years away, in 2025.

    Five years in 2020, then 2025 , etc ...

    About the same time period we get our flying cars. :)
