A Chinese research team has developed a data-driven control system for tokamak plasmas that could bring sustainable fusion energy a step closer to reality, according to a paper published in Communications Physics, a journal under the Nature portfolio.Fusion
The “artificial sun” is a clickbait term for the plasma in a fusion reactor. The tech’s been around for decades (apparently the first tokamak was built in the USSR in the 50s) but they have yet to find a way to make the plasma last on its own (the record is a little over 20 minutes apparently) or to actually make them generate power.
They have gotten them to generate power, by which I assume you mean give off more energy than was used to create the reaction. But they haven’t gotten them to sustain that.

Didn’t know that! Guess it’s good progress, but still definitely a long way from actually having fusion reactors as a power source.
