An infographic describes the science of fusion reactors. The left-hand side of the graphic details nuclear fusion, a reaction in which two nuclei fuse to form one heavier one, releasing massive amounts of energy. The fusion of deuterium and tritium to form helium is shown in a diagram. The right-hand side of the graphic introduces two types of fusion reactors: magnetic confinement reactors, which use a magnetic field to confine deuterium and tritium plasma, and inertial confinement reactors, which use laser pulses to trigger fusion in small pellets of deuterium and tritium. A short list of fusion milestones is also provided.
