Also could do a magnonic fusion reactor.
Magnetic Islands
But there may be a way to force the plasma into doing what we want more predictably and efficiently, as detailed in a new theoretical paper published in the journal Physics of Plasmas.
The Princeton team found that shooting radio frequency waves that super-heat fusion reactions inside a reactor could potentially reduce the chance of “magnetic islands” — bubble-like structures that can throw fusion reactions out of whack by triggering sudden releases of energy.
