Major breakthrough on nuclear fusion energy

        February 9, 2022 BBC | UK | nuclear: fusion

Having replaced carbon in the tokamak walls with less absorbant beryllium and tungsten, UK-based JET has broken its previous 1997 record, producing 11 MW of power over 5 seconds (59 MJ). The hydrogen isotopes D and T fuse at about 100 million degrees. Although not yet breakeven, the result bodes well for the under-construction ITER setup in France.
