(Reuters) -U.S. scientists have achieved net energy gain in a fusion reaction for the second time since December last year, the Lawrence Livermore National Laboratory (NYSE:) said on Sunday.
Scientists at the California-based lab repeated the breakthrough in an experiment in the National Ignition Facility (NIF) on July 30 that produced a higher energy yield than in December, a Lawrence Livermore spokesperson said.
Final results are still being analyzed, the spokesperson added.
Lawrence Livermore achieved a net energy gain in a fusion experiment using lasers on Dec. 5, 2022. The scientists focused a laser on a target of fuel to fuse two light atoms into a denser one, releasing the energy.
