South Korea's artificial Sun sustains 102‑second burst, promising energy breakthrough

South Korean researchers demonstrated an artificial Sun that ran for 102 seconds. The device maintained its operation continuously for that full duration. The experiment aims to replicate the nuclear fusion that powers the natural Sun. A 102‑second run marks a notable milestone for the technology. Experts suggest the achievement could influence the future of energy generation. The breakthrough may bring fusion‑based power closer to practical use. Researchers plan additional experiments to extend run times and improve performance. Industry watchers will monitor how the development shapes energy strategies.
