No matter how you do it generating electricity causes friction, friction needs power to overcome it, so using anything to generate electricity from these points on a vehicle will drop your MPG in a direct ratio to the amount of energy generated minus the efficiency of the generator. You will come out with less power than you had to begin with. You can't get something for nothing. It is possible to use something like a sterling engine to use waste heat but you cannot use a generator to gain any energy from the motion of the vehicle other than from braking force.
