Yes been here before back in when was it, 1956 oor so, the Russian
Exhibition in London showed us magnetic confinement systems that appeared to
generate fusion. the snag was that it was for such a tiny fraction of a
second that it was hardly of much use and the energy input was huge compared
with output, and of course actually getting at the output energy caused lots
of issues as materials had not been made that could be used near such a hot
thing.
However as has been the case for many years since, it was said that Fusion
power from seawater was less than 10 years away.
Ahem...
OK it might a lot better now than then but the same fundamental issues of
scale and heat and keeping it going seem to still be the problem.

It doesn't seem to say that fusion has been achieved, only that plasma
has been generated and confined. Neither does it say that any planned
fusion generates more energy than it takes to run the thing, nor how
the energy surplus, if any, might be extracted.

Well it sounds like they've made a big step forwards.

That's the whole point of press releases.

Old design, been mucking with it for years. need more cash.
