Fusion power is a form of power generation in which energy is generated by using fusion reactions to produce heat for electricity generation. Fusion reactions fuse two lighter atomic nuclei to form a heavier nucleus, releasing energy. Devices designed to harness this energy are known as fusion reactors. The fusion reaction normally takes place in a plasma of deuterium and tritium heated to millions of degrees. In stars, gravity contains these fuels. Outside of a star, the most researched way to confine the plasma at these temperatures is to use magnetic fields.
