Not so much carving a new path as looking for one. Maybe be gyrotrons can heat the plasma enough, but planing to do experiment which can test whether they can isn't exactly carving a new path - more just looking at a possible new path. > Bye bye ITER and that otehr fusion attempt mayonaise thing > https://www.sciencedaily.com/releases/2024/08/240806131357.htm > Researchers dig deeper into stability challenges of nuclear fusion -- with mayonnaise > > Now all I am waiting for is a 10 year old kid doing a better than break even fusion experiment in its parents kitchen... You may have to wait a long time. Mayonaise may exhibit Rayleigh-Taylor instability, but the lessons it might be able to impart would be difficult to translate into totomak design. -- Bill Sloman, Sydney -- This email has been checked for viruses by Norton antivirus software. www.norton.com
