Is This the ‘Kitty Hawk Moment’ for Fusion Energy?

Tomorrow, the U.S. Department of Energy is expected to announce that the era of fusion power is finally upon us: Scientists at the Lawrence Livermore National Laboratory, in California, have generated energy with a controlled nuclear fusion reaction. It has already been hailed as a transformative moment, even as the nature and reality of that transformation are nigh-impossible to discern.

As first yesterday by the , Energy Secretary Jennifer Granholm is expected to announce that researchers have ignited a small fusion reaction that produces more energy than it consumes. The federal government is calling this “a major scientific breakthrough,” and if the rumors are true, that description will in some sense be justified. For the better part of a century, scientists have been trying to use the power of fusion—the nuclear process that makes
