Last spring, physics writer Andrew Grant reported on the lack of progress by the main U.S. nuclear fusion effort (“Ignition failed,” SN: 4/20/13, p. 26). As the researchers still contend, laser-initiated fusion should work. It works on paper. But in practice, even a set of extremely powerful lasers failed to trigger the fusion of hydrogen nuclei and the concomitant chain reaction and release of net energy expected.
In February, the National Ignition Facility scientists at Lawrence Livermore Na...
