France has upped the ante in the quest for fusion power by maintaining a plasma reaction for over 22 minutes – a new record. The milestone was reached on February 12 at the Commissariat à l'énergie atomique et aux énergies alternatives (CEA) WEST Tokamak reactor.

    A headline without calling it an “Artificial Sun”?!

        Don’t worry, it will stabilize

      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.

          Even the core only has an output of 200-300W/m^3.

              Right, for the Americans here that hate metric.

        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.

            It produces about the same power per cubic metre as compost does, which is pretty crazy when you think about it.

            What I’m hearing is that we should mine the sun and make better use of all that fuel.

        Someone once told me a sun is just a fusion nuclear pile reactor and… Like… I guess.

      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.
