Why
"Sparkspin"?
Diary document 1980:~

"From my very meagre knowledge of Particle Physics and the on-going quest for cheap energy derived from torus-like plasma containment devices like the Tokomak, I knew that because of the elastic & springy nature of the plasma, scientists find it very difficult to maintain its central position within the vacuum chamber.

It has occurred to me that, rather as the rifling of a gun barrel induces stability to the projectile by making it spin, if the "spark" (plasma) could be made to spin then the same kind of stability might be achieved.

This would be too difficult in a torus but how about inside a music string?"
