          No, but some guy proved that we could use that to our advantage. If you don’t use the magnetic constrictors to compensate for the heat from the fusion expanding the vessel, you can have it enter fusion and leave fusion several times a second. Wrap the thing in copper wire coils, and you have now got your vessel in a state of flux, and producing enough power to blackout your local grid, and get lots of fines from the feds in less than 5 seconds of runtime. He obviously didn’t continue working on that particular method of generating power with a Tokomak

      The amusing thing is that the sun is actually quite a shit fusion reactor. It’s power per unit volume is tiny. It just makes it up in sheer volume. A solar level fusion reactor would be almost completely useless to us. Instead we need to go far beyond the sun’s output to just be viable.

      It’s like describing one of the mega mining dumper trucks as an “artificial mule”.

        I think this energy density math really depends on whether only the core or the whole surface area is taken into consideration.

        Arguably, the nearby sun scale fusion reactor has been fairly useful for us. Nowadays we can convert its output directly into electricity using solar cells

          I never said it wasn’t useful, just a very low efficiency reactor. Then again, if it was better, it would burn out faster, which would be bad for life on earth.

              That’s part of the reason a moon base could be viable. The sun outputs a reasonable amount of helium 3, which is great for fusion reactions. Unfortunately it tends to sit at the top of our atmosphere and get blown away again. On the moon, it gets captured by the dust in collectable quantities.

      They say “artificial sun” because that’s what it is though, there’s no fusion reactions here they’re just microwaving hydrogen to millions of degrees to study the kind of thing that would happen IF somebody runs a fusion reactor for 22 minutes.

          That was such a culture shock when I went to the us for the first time.

          In Germany and many places in Europe do not think of burgers as sandwiches. I was so confused when I ordered a sandwich and got something like a burger.

          I expected something like this

          I expected something like this. My confusion must’ve been quite the sight, the waitress even seemed concerned. Tasted great though.

            Only difference between that and a burger is a burger is usually on a roll, not slices of bread. (And a burger is always hot, but then so are some sandwiches.)

    This is freaking awesome. Only a few years ago it was exciting to see a fusion reaction last a fraction of a second.

    Why don’t we use “shatters world record” like the pro-China articles where they did this for 16 minutes?

    I know why.

          We’re using graphene! Almost entirely for it’s electrical properties true, but we’re using graphene doped batteries in consumer electronics currently. We also use fusion and ITER research for a whole lot more than just power generation - plasma dynamics, just one tiny subfield concerned with physics, has applications in everything from radio transmission beam forming techniques to satellite engines to magnetodynamic modeling to the EMI shielding on your vacuum cleaner.

      Plastic Straws. Plastic cups. Wrapping indvidual food items in plastic and then putting them in a larger plastic bag which you carry home in an even larger plastic bag.

    France’s 22-minute plasma reaction is a bold stride toward sustainable fusion energy but remains experimental.

      Yes but 22 minutes is longer than 17 minutes

      Think of it like a pizza oven

      I can’t find a reference to that but China did 17 minutes in January this year. I think you’re confusing the announcement that they increased power by 17x while maintaining plasma.

      This test was 20 minutes at a higher power setting without being incredibly destructive, that’s their milestone.

      Agreed. Plus, when talking about that reactor you get to say “stellarator”, which is always fun.
