fusion ignition
Fusion ignition is the point at which a fusion reaction becomes self-sustaining, meaning the energy produced by the reaction is enough to sustain further reactions without needing additional energy input. This process occurs when lightweight atomic nuclei, such as those of hydrogen, combine to form heavier nuclei, releasing vast amounts of energy, much like what powers the sun. Achieving fusion ignition is a significant goal in energy research, as it could lead to a nearly limitless and clean energy source, potentially transforming the way we produce electricity and power our world.

Fusion ignition refers to the point at which a nuclear fusion reaction becomes self-sustaining, releasing more energy than is inputted. This process occurs when two lighter atomic nuclei merge to form a heavier nucleus, producing significant energy, similar to how the Sun generates its power. Achieving fusion ignition is a key goal in energy research because it offers the promise of a nearly limitless, clean energy source, using fuels like hydrogen isotopes. Scientists are experimenting with various approaches, including magnetic confinement and inertial confinement, to reach this essential milestone in fusion technology.
