Nuclear fusion lab sets record for most energy created with single reaction

Since 1983, scientists have used England’s Joint European Torus (JET) to recreate nuclear fusion, the merging of atoms that powers the sun and other stars, in Britain. An effective nuclear fusion setup could give us immense quantities of clean energy.

Now, during the last days of its four-decade-long life, JET has set a new record for the most energy created in a single fusion reaction. JET’s new record is the latest milestone in an exciting few years for fusion. With each milestone, fusion scientists inch closer — slowly, very slowly, but steadily — toward constructing a commercial fusion power plant that can plug into the grid.
