Fusion power has the potential to be a major source of clean, safe, and abundant energy in the future. A new break though has been discovered by a team in America, the team managed to get more energy out from the enormous amount of energy that was required to start the fusion reaction. Fusion occurs when atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy in the process. This is the same process that powers the sun and other stars. Unlike nuclear fission, which is the process used in current nuclear power plants, fusion does not produce dangerous radioactive waste and has the potential to provide a nearly limitless source of energy. However, fusion is extremely difficult to achieve and control, and significant technical challenges must be overcome before fusion power can become a practical reality.
