Friction of air to materials could be reduced by allowing air to be used by these pores to not only cool but to generate power as it then would exit the back of the vehicle.

Coils around the axel. The axel made of earth metal magnets you say would create more weight than necessary? How?

Using the movement of air to generate power will cause more friction that it would just to use it to cool, the weight of the magnets is secondary to the friction created by generating electricity with the magnets. Your best bet is to use a small engine to generate electricity on demand and use electric motors at the wheels. That way you can eliminate the loss due to friction in gears and transmissions and run the motor at it's most efficient speed a when it is needed. an aerodynamic body will also help with efficiency. the thing to remember is that you can't get something for nothing, any attempt to gain energy is always offset by friction or waste heat. eliminating friction by eliminating gears and u-joints and other power transferring elements of the drive train are the best way to go. Regenerative braking is the only practical way to generate energy directly from motion and you are recovering energy lost to brake friction.
