The South Korean artificial sun, which goes by the name KSTAR (Korea Superconducting Tokamak Advanced Research), has made an important scientific discovery concerning nuclear fusion by being able to sustain plasma in high-confinement mode for a period of 102 seconds while simultaneously managing to keep plasma temperature at 100 million degrees centigrade for 48 seconds. This development by the Korea Institute of Fusion Energy (KFE) is another move towards achieving clean fusion energy, whose ability to generate unlimited amounts of electricity with little to no carbon emission is promising.
Solar actually overtook nuclear as least-killy-per-gigawatt about a year (maybe even two, now) ago, although obviously killing people isn’t the only bad thing a system of power generation can do.
It’s not hard to overtake nuclear when we’re shutting nuclear down. Thankfully that trend is reversing, because if we had a full nuclear build out, we wouldn’t really need anything else.
Especially SMRs, those are quite amazing, well, amazing for something that just heats water to make steam to drive a turbine.
