China’s latest fusion project promises to generate five times more power than it consumes, setting a blistering pace unmatched by its American rivals. If successful, this could rewrite the playbook on fusion energy and edge the world closer to a carbon-free future.
At the heart of this endeavor lies the Burning Plasma Experimental Superconducting Tokamak—BEST for short—a doughnut-shaped vessel where hydrogen isotopes collide at temperatures hotter than the sun’s surface. I still recall the first time I learned that fusion mimics the processes powering stars; it felt like peeking behind the universe’s curtain.
Thanks to superconducting magnets and advanced cooling systems, the BEST reactor is engineered to sustain plasma long enough to achieve a genuine net energy gain, rather than simply breaking even.
