US Scientists Repeat Fusion Power Breakthrough For a Second Time

The Financial Times reports:U.S. government scientists have achieved net energy gain in a fusion reaction for the second time, a result that is set to fuel optimism that progress is being made towards the dream of limitless, zero-carbon power... "In an experiment conducted on July 30, we repeated ignition at NIF," the laboratory said. "As is our standard practice, we plan on reporting those results at upcoming scientific conferences and in peer-reviewed publications..." Although many scientists believe fusion power stations are still decades away, the technology's potential is hard to ignore. Fusion reactions emit no carbon, produce no long-lived radioactive waste and a small cup of hydrogen fuel could theoretically power a house for hundreds of years... [T]he improved result at NIF, coming "only eight months" after the initial breakthrough, was a further sign that the pace of progress was increasing, said one of the people with knowledge of the results.
