Imagine a world powered by limitless, clean energy. A UK company just made a giant leap towards commercial nuclear fusion. Tokamak Energy's new high-temperature superconducting (HTS) magnet system, the first of its kind, successfully generated a staggering 11.8 Tesla magnetic field, proving it can create the intense conditions needed to contain a star on Earth. This complete system test, a critical step beyond single magnet demonstrations, handled seven million ampere-turns of current, validating the technology's ability to withstand the extreme forces inside a fusion reactor. This breakthrough provides crucial engineering data to scale the technology for future power plants, getting us closer to safe, limitless energy on the grid. Beyond fusion, this HTS tech could revolutionize other industries, powering ultra-efficient electric planes or next-generation data centers.
