I still like capacitors for storing electricity in the long run. As dielectrics get better and better it's only a matter of time before we truly do have our supercap. Batteries are electro-chemical devices. Capacitors work on an entirely different principal. No chemical change takes place as it is charged and discharged. Unfortunately a magnetron as in your microwave oven only operates on one discrete frequency because of the way it is made. If you want to really do damage with an EMP it has to be over a frequency width of many octaves of and also very high power to be effective. So as an engineer who has worked with RF emitting devices most of my life (some into the megawatt range) I am not the slightest bit worried about electric cars generating an emp pulse of any significant magnitude. The big problem Hawk is rise time.
