Fusion Reactors
Fusion reactors are devices that use nuclear fusion reactions to generate heat and electricity. In a fusion reaction, two atomic nuclei are combined to form a heavier nucleus, releasing a large amount of energy in the process. The challenge in building a fusion reactor is to create and maintain the conditions necessary for the fusion reaction to occur, including high temperatures and pressures. One approach is to use magnetic confinement to contain a plasma of hydrogen isotopes, such as deuterium and tritium, and heat it to the point where fusion occurs. Another approach is to use inertial confinement, where a small pellet of fuel is compressed by intense laser beams to create the necessary conditions for fusion. Fusion reactors have the potential to provide a virtually limitless source of clean energy, with no greenhouse gas emissions or long-lived radioactive waste.
