Lab Repeats Nuclear Fusion Feat, With Higher Yield
Arthur T Knackerbracket has processed the following story:
US scientists responsible for a historic nuclear fusion breakthrough say they have repeated the feat-this time achieving a greater yield of energy.
The Lawrence Livermore National Laboratory stunned the world in December when it announced it had carried out an experimental nuclear reaction that put out more energy than was put into it, a holy grail of science in the quest for unlimited, clean power to end the era of fossil fuels.
"We can confirm the experiment produced a higher yield than the December 2022 experiment," public information officer Paul Rhien said Monday in an emailed statement, without disclosing specific figures.
He added the California lab planned to report the results at upcoming scientific conferences and in peer-reviewed publications.
[...] Nuclear fusion has been touted by its supporters as a clean, abundant and safe source of energy that could eventually allow humanity to break its dependence on coal, crude oil, natural gas and other hydrocarbons driving a global climate crisis.
However, there is still a long way to go before fusion is viable on an industrial scale, providing power to homes and businesses.
[...] During December's experiment, the lab used 192 ultra-powerful lasers to deliver 2.05 megajoules of energy to a tiny capsule smaller than a pea containing isotopes of hydrogen. It produced 3.15 megajoules of fusion energy output.
While the result was a net energy gain, 300 megajoules of energy was needed from the electrical grid to power the lasers.
