Nuclear fusion "breakthrough" reportedly arrives
Energy Secretary Jennifer Granholm is expected to announce a major step forward in nuclear fusion energy on Tuesday.
Why it matters: Decades of effort have gone into fusion energy, which promises almost limitless carbon-free power — without the dangerous waste from traditional fission reactors.
Driving the news: The breakthrough came in the past two weeks at the National Ignition Facility of the federal Lawrence Livermore National Laboratory in California, the Financial Times reported in a scoop.
- Granholm will announce scientists for the first time have produced "a fusion reaction that creates a net energy gain — a major milestone in the decades-long, multibillion-dollar quest to develop a technology that provides unlimited, cheap, clean power," the Washington Post adds.
Reality check: Progress in showing conceptual viability would be just one stop on the long scientific, technical and financial road to commercializing this long-elusive holy grail.
What's next: Granholm's announcement tomorrow is billed as a "major scientific breakthrough."
