>As a refresher, inside the donut-shaped (or, sometimes, more spherical) containment of a tokamak, sun-hot plasma swirls in a circle thatโ€™s held in place by supercooled electromagnets. This magnetic field is the only thing floating between 360-million-degree plasma and a bunch of human-made materials that obviously canโ€™t sustain that temperature. The plasma results from smashing different nuclei together, fusing them rather than splitting them. This requires a huge energy investment, which critics say means fusion will never really get off the ground. And so far, all tokamaks work for just a scant few seconds at lower temperatures before something goes wrong. This is why EASTโ€”which just properly โ€œturned onโ€ last Decemberโ€”running for 101 seconds at 120 million Celsius is such a huge deal.
