48 seconds. I predict a glut of helium. balloons for everyone

Last one I read about is just constantly and very quickly (far quicker than human abilities) adjust the magnetic field around the plasma in order to keep it stable and in place. They've been (or at least one team was) using AI to go over data and control and predict the field adjustments, because only reacting after the plasma starts to move hasn't been quick enough.

    Yes, that'd be TAE technologies.

    The algorithm was called the optometrist, it was paired with a human operator to more quickly converge on the correct settings for stable plasma by having the machine randomly tweak various meta-parameters, while the human would generally decide whether the current settings were "better" or "worse" than the previous pulse.

    I wonder if there isn't a stable chamber shape that promotes turbulence in a controlled manner in order to prevent it getting out of hand? A little bit like the dimples on a golf ball create micro pockets of turbulence promoting laminar flow.
