I have been thinking about fusion for many years. Having a bottle of hot matter would be fascinating. With a early clean start from Ms. Amasa S. Bishop's book, Project Sherwood, my privately nursed thinking led to a configuration of electric and magnetic fields where a central magnetic hoop is electrical ground, The smallest in bore and most highly magnetized. Before and after the central hoop coaxially and co linearly is a row of hoops that are progressively larger (Possibly not by much), weaker, and more highly positively charged. The plasma is allowed to become positively charged because electrons waste energy and are not involved in nuclear reactions. The nuclear particals are confined because they can't escape axially because of the electric field and can't escape radially because of the magnetic field. The magnetic field is curved in an extra stable shape. The plasma may be heated by compression in the fields, injection of energetic particals, electrical induction and lasers. The magnets can be powered by individual generator armatures on a ceramic shaft if the confinement voltage is too high for a transformer. With the diode array recycling heat, energy is not lost. Diode arrays are probably a more useful general energy source. Fusion is not well funded. I am 56, adult discussion rules apply.
