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.

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.
