As regards replication of electrical output—oriented flux core However, it has been commonly stated that Joe Flynn simply devices, certain important details need to be stated. For example, developed the mechanical apparatus and that the MEG, with its electrical functionality, is distinct and more advanced than the mechanical Flynn apparatus. But this is shown not to be the case by a careful examination of the Flynn patent, in which the following is stated in the Power Conversion section: "The construction shown in Figure 45A (a) utilises four control coils and a single per- manent magnet, and the construction shown in Figure 45X uses two control coils and two permanent magnets.
