to put this in perspective...when operating in the vehicle the starter,ignition,headlights,fuel injection etc draw off the battery.when the voltage drops down because of these losses the alternator switches on to recharge the system using engine power.since the battery can become charged in the given scenario it more or less shows that all things being equal the alternator windings are moving more electrons simply because they are more massive than the windings in the drill motor.drill motors are designed to work efficiently as far as ft/lbs to make the battery last longer.alternators are designed to make up a deficit in voltage very quickly.this is a matter of engineering in my opinion.many systems including mains power are not engineered to be efficient or else we would all have a bank of batteries in our homes charging parasitically off the current surplus itself and not necessarily terminating in the batteries.the whole system is set up to waste energy and thereby get your money...lol
