Nuclear Fusion: The Quest for Clean Energy
Nuclear fusion is a highly anticipated power source that could provide clean, endless energy. It involves fusing two atoms together, which releases a significant amount of energy. Unlike nuclear fission, fusion produces minimal radioactive waste and is considered safer. However, achieving controlled fusion on Earth is challenging due to the immense temperatures and pressures required. The tokamak, a donut-shaped device that uses magnetic fields to confine a superheated plasma, is a leading design for fusion reactors. While the international project ITER aims to demonstrate fusion's feasibility, private companies have also joined the race to bring fusion power closer to reality. If successful, fusion could revolutionize energy production and even enable advanced space travel.
