True, but from what I read, the heat is maintained inside the magnetic field that contains the plasma. That would be the plasmoid in the case of the DPF, if the technique were applicable to the DPF. As I see it, the largest difference is that the other plasma system uses a (more) static magnetic field, and that may make the technique a non-starter for the DPF – which uses a decidedly non-static field. Still, I thought it worthy of mention so that those who understand the DPF better could evaluate its potential. (if any)
