Part 6/10:
Despite decades of research and development, the path to practical fusion power has been slow and arduous. Many early fusion projects in the 1950s and 1960s promised breakthroughs within a couple of decades, only to be met with disappointment as the technical challenges proved far more difficult than anticipated.
Over the years, there have been numerous fusion reactor designs and experiments, each with its own successes and setbacks. Projects like the Joint European Torus (JET) in the UK, the Japan Torus (JT-60) in Japan, and the Korea Superconducting Tokamak Advanced Research (KSTAR) reactor in South Korea have all made important advances, pushing the boundaries of plasma confinement and heating.
