Fusion research focuses on developing energy through the process of nuclear fusion, where atomic nuclei combine to form a heavier nucleus, releasing vast amounts of energy. This process powers the sun and has the potential to provide a nearly limitless and clean energy source for Earth. Scientists aim to replicate these conditions on a smaller scale using advanced technologies. Key projects in fusion research include the International Thermonuclear Experimental Reactor (ITER) and various tokamak designs. Researchers explore different methods, such as magnetic confinement and inertial confinement, to achieve the high temperatures and pressures necessary for fusion to occur efficiently and sustainably.
