US fusion startup makes history by converting plasma energy directly into electricity (Aman Tripathi, Jul 01, 2026, Interesting Engineering)
An experimental fusion reactor in Madison, Wisconsin, has achieved a technical milestone by converting plasma energy directly into usable electricity for the first time in the private sector. The successful trial used the Wisconsin HTS Axisymmetric Mirror, a research device operated alongside the University of Wisconsin-Madison. […]Kieran Furlong, the chief executive officer of Realta Fusion, noted that while the concept has long been a subject of theoretical discussion in the industry, this test represents the initial practical application of the method on an operational fusion device by a private firm.
