Nuclear Fusion breakthrough hits hurdles as five experiments fail

Japan Times, BY DAVID R. BAKER, BLOOMBERG 17 May 23,

The U.S. government lab that made a long-awaited breakthrough in fusion energy late last year has run five similar experiments since then without being able to replicate the results.

The milestone came in December as the the Lawrence Livermore National Laboratory near San Francisco reported achieving the first fusion reaction that produced more energy than it took to create — a threshold known as ignition. The achievement opened the possibility of power plants one day running on nuclear fusion, the same energy source as the sun.

Since then, the lab has run five similar experiments, shooting the world’s most powerful laser at small diamond capsules filled with hydrogen, said Lawrence Livermore Director Kim Budil. But so far, ignition hasn’t been achieved again…………….

Speaking at an event at the lab Monday celebrating December’s breakthrough, U.S. Energy Secretary Jennifer Granholm said the federal government would spend $45 million over the next four years to create a series of research hubs pursuing the kind of fusion achieved at Lawrence Livermore, known as inertial confinement.
