Electric energy with an artificial sun

China’s “artificial sun”—formally known as Experimental Advanced Supercunducting Tokamak (EAST), based in Hefei—is able to maintain a high-grade, steady-state refinement plasma operation for 17 minutes and 46 seconds. This figure nearly triples the previous world record, of 6 minutes and 43 seconds, also established by EAST in 2023. Faced with this so-called artificial sun, the question is what the future of electric energy will be? Fusion react…
