China's "artificial sun" marks development in nuclear fusion

The video discusses a fusion reactor reaching 100 million degrees Celsius, over six times the Sun's core temperature. It introduces the Experimental Advanced Superconducting Tokamak (EAST), which uses magnetic fields to contain hot plasma. The nuclear fusion process, where light atom nuclei combine to form a heavier atom, releasing energy, is explained. The ITER project, a multinational effort to harness fusion energy, is mentioned, highlighting that fusion fuels are costly but do not emit harmful pollutants.
