Nuclear fusion heat record a ‘huge step’ in quest for new energy source

Nuclear fusion just hit a stunning new benchmark: scientists at the JET facility in Oxfordshire sustained a reaction for five seconds, releasing 59 megajoules of heat — more than double what the same machine produced in 1997. Inside the doughnut-shaped reactor, plasma reached 150 million degrees Celsius, roughly ten times hotter than the sun’s core, fusing hydrogen isotopes the same way stars do. The five-second burst matters because it proves the fuel can be burned stably and repeatably — the foundation any future power plant will need. If researchers can keep building on this, fusion’s promise of abundant, carbon-free energy drawn from seawater could reshape what a just, livable energy future looks like for everyone.
