US scientists have achieved net energy gain in a fusion reaction for the second time since December last year, the Lawrence Livermore National Laboratory said on Sunday.
Scientists at the California-based lab repeated the breakthrough in an experiment in the National Ignition Facility (NIF) on 30 July that produced a higher energy yield than in December, a Lawrence Livermore spokesperson said.
Final results are still being analyzed, the spokesperson added.
Still the usual “Decades away from practical deployment.”
