Perpetually driven electric car

[Problemsolver]

I would think that using every bit of energy that a moving electric car produces, it would be able to sustain itself. Geared alternators on each wheel, pinwheels to use wind energy to power the interior electronics, plus solar panels. Even putting stators on the rims with a coil in the hub, making the wheel an actual generator itself. All this power could be stored in fairly small capacitors, or just directly back into the battery. Why not?

Regenerative braking is similar to what you're proposing. Unfortunately you cannot recover 100% of all of the energy due to losses to friction, electrical resistance, and others.
