Not sure where you're headed with this, but I can see a point of potential relevance. For instance, you could use the starter to drive a three phase alternator, chop the pulses so they squeeze together without overlapping, then hook it up to a WFC. If you're going to power the starter with HV, its wire size can't be too small, but doesn't have to BE small. The important factor is the HV has to be a pulse. You need to use a pulse forming technique, just as you would with an electrically produced EMP, except it would be in line (in the circuit), rather than fed to a coaxial ring antenna. So try chopping the HV and connect a metal funnel in the circuit going to the motor, for a biphasic shape resonance tuning effect. And be sure to use at least 20 feet of large gauge wire between the funnel and the motor, to allow the pulse to condense, before doing its magic in the motor. edit: Otherwise, you might radiate a pulse anyway, frying the electronics in your car and everything else within two or three blocks.
