The Joint European Torus (JET), one of the world’s largest and most powerful fusion machines, has demonstrated the ability to reliably generate fusion energy, while simultaneously setting a world record in energy output. These notable accomplishments represent a significant milestone in the field of fusion science and engineering. In JET’s final deuterium-tritium experiments (DTE3), high fusion power was consistently produced for five seconds, resulting in a ground-breaking record of 69 megajoules using a mere 0.2 milligrams of fuel.
