Physics On the Laser-Fusion Milestone [long_description] On December 5, 2022, the National Ignition Facility recorded the first energy gain in fusion history. Daniel Jassby follows up on his recent essay to explain that, while laudable, these results have done little to advance fusion energy’s distant future, since the various technologies necessary to support such a future do not yet exist.

Physics The Quest for Fusion Energy [long_description] In recent years, a steady flow of press releases from nuclear fusion research projects have hailed breakthrough advances and new record yields. Despite repeated claims that the prospects for commercialization have never looked brighter, the stark reality is that practical fusion-based electric power remains a distant prospect. It is likely unachievable anytime in the next half century.
