  There is that, but there is the whole 'coil' thing. Generally conductors have something called the 'skin' effect, which is that as they conduct the electrons move along the outer surface. So the skysphere's outer surface forms a ring where the current will move out to the edge, and then back to the center before going into the ground (or more literally coming from the ground but that is not important here). The change in current in the outer rings will create a magnetic pulse inside the ring that is proportional to the change in current, per Ampere's law. And for conductors that are inside the sphere part, they will experience a very large change in magnetic flux, which will then induce an electric current in any conductors they have inside of them. It is entirely possible that every piece of electronic equipment inside the sphere will be destroyed by the resulting EMP. Or simply magnetized. But I'd really want to compute flux lines based on the lightning hitting the top, splitting down for four 'rings' (Kirkoff's law) and then going on down via the center into the earth.
