Nuclear fusion is a research area focused on achieving controlled nuclear fusion reactions, which is the process that powers the sun and other stars. This involves combining atomic nuclei to form heavier nuclei, releasing large amounts of energy in the process. Researchers are exploring various methods to harness this energy for practical use, such as generating electricity with minimal waste and environmental impact. Some of the key challenges in nuclear fusion research include creating and maintaining the necessary extreme conditions of temperature and pressure, controlling the plasma where the fusion reactions occur, and developing materials that can withstand the intense heat and radiation produced. Successful development of nuclear fusion technology could provide a virtually limitless source of clean energy for the future.
