Or perhaps I’m looking at it all from the wrong approach. Instead of dumping more thermal energy into the plasma to obtain higher temperatures …. perhaps it needs higher pressure instead to help it along. Would the interaction of some sort of external electrical or magnetic field help to pinch or compress the plasma vortex even tighter? More than likely, it would cause some sort of instability that would have the opposite effect of breaking – up the plasma vortex. Or perhaps it could be made to convet the thermal energy and high temperatures into greater compression.
