Deep dives
Understanding Nuclear Fusion
Nuclear fusion is the process of combining small hydrogen molecules, specifically deuterium and tritium, to form a larger molecule and release energy through a reaction that can be described by Einstein's equation, E=mc². This method differs significantly from nuclear fission, which involves splitting larger molecules and is more commonly understood. The primary challenge with fusion lies in creating and maintaining extreme conditions such as high temperature, pressure, and stable time frames needed for the fusion process to occur. Despite existing knowledge about initiating fusion, controlling it for safe energy production remains a major hurdle.
