Alan Boyle at NBC News has an article titled “Rays of Hope: Fringe Fusion Ventures Take Small Steps Toward Energy Leap”. It’s basically a news roundup of alternative fusion efforts: Tri Alpha Energy’s recent publications in Physics of Plasmas and Nature Communications, General Fusion raising another $27 million, the ARPA-E ALPHA grantees Helion Energy and a joint venture between the University of Washington and Lawrence Livermore National Laboratory to build a large-scale Z-pinch device, and EMC2 Fusion’s upcoming publication in Physical Review X. Lockheed Martin and LPPFusion get brief mentions near the end of the article.
