China has completed the construction of the world's largest thermonuclear magnet, overcoming one of the key obstacles on the path to mastering controlled thermonuclear fusion technology, which could provide the country with virtually unlimited energy
China announced the completion of the development of two key superconducting magnets for a thermonuclear reactor, including the world's largest toroidal magnet, measuring 21 meters in length and weighing 582 tons
Following successful testing, the devices have been deemed fully ready for use in a future experimental facility. Both magnets were entirely produced using China's domestic technological base (from superconducting materials to complex manufacturing processes)
They are designed to confine plasma at temperatures exceeding 100 million degrees Celsius and trigger a sustained thermonuclear fusion reaction
The successful creation of the magnets resolves approximately 80% of the project's most complex engineering challenges. The next stage involves reactor assembly and extended testing
China expects to complete the construction of the experimental reactor by 2027, with the first demonstration of thermonuclear energy generation anticipated around 2030
