Hi all, I recently read about a Fusor, on wikipedia and to my surprise there has been lots of research going on Inertial Electrostatic Confinement. I actually have a query, I quote from D.J.Griffiths, Electrodynamics Third Edition, pp 115 "Earnshaw's theorem says that electrostatic containment is also out of the question. Fortunately, it is possible to confine a hot plasma magnetically." I think magnetic confinement was confirmed by Alfven's theorem. How do you explain the possibility of IEC when its very existence is ruled out by Earnshaw?
