US Department of Energy officials announced a history-making accomplishment in nuclear fusion Tuesday: For the first time, US scientists produced more energy from fusion than the laser energy they used to power the experiment.
A so-called “net energy gain” is a major milestone in a decadeslong attempt to source clean, limitless energy from nuclear fusion – the reaction that happens when two or more atoms are fused together.
The experiment put in 2.05 megajoules of energy to the target and resulted in 3.15 megajoules of fusion energy output – generating more than 50% more energy than was put in. It’s the first time an experiment resulted in a meaningful gain of energy.
