The one thing about the Skunk works design is that is it much much simpler than the current design. IF (and that is a big one), there is a design that actually works, I suspect it will be a simpler design rather than the monstrosity that people have been testing the last bunch of years.
I am skeptical, but the same time,I truly hope I am wrong.
MIT research folks made a proposal for updating the fusion generator , using the current 'tomak' design, but with more modern 'off the shelf' equipment.
Now, because of the nature of the work, I wouldn't be surprised if many details are considered 'secret' (It has military applications after all), and not being subject to patents. However, it does show they have been working on it, and being fairly quiet about it
