Fusion Is Having a Moment - IEEE Spectrum
Last December, Lawrence Livermore National Laboratory’s National Ignition Facility finally succeeded in forcing the hydrogen isotopes deuterium and tritium to undergo a self-sustained fusion reaction. It was an encouraging advancement, though not exactly a breakthrough. NIF’s small net energy gain didn’t factor in the energy it took to fire up the 192 ultraviolet lasers that initiated the reaction, which lasted “for the briefest blink of a moment,”
