Rather than have the power coming from the wheel, it just comes from the source: The engine itself. It spins too, which powers the water pump and fan (at least, assuming you don't have an electric fan) via the belts, and that spinning also powers the alternator at the same time, which is basically the same as what you're saying...
And since the headlights, stereos and basically every other accessory runs off the battery which is charged no problem by the alternator, I fail to see your reasoning here.
Besides, from that picture, your method has many flaws that would require constant maintenance.
Oh! I thought you were talking about something totally different.
And with my pictures, that was just for the ideas ;p.
And on another side note: Like your car runs on battery, but instead of gas stations, you could have recharge stations.. Like battery swap outs.. Or something.
