They are almost totally theoretical, because any attempt to actually measure them distorts the field, reducing it in general. For comparison, you should know that there is a field of about 100V/m above a flat meadow on any cloudless sunny day, but when we walk out into that field the field distorts and we feel nothing. On stormy days, the field gets much higher, but I don't know the figures for that. What field would be felt inside a car or inside the ECU would depend on the effectiveness of the shielding, the length of the wires leading outside the ECU box, and the frequencies present in the EMP. The currents generated by these fields would then depend on the impedances, which are also a function of frequency. It's not a simple problem at all. Who knows, we might do rather well, but "survival" in such a situation would still only be temporary for the vast majority of us. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
