Perpetually driven electric car

Click For Summary
SUMMARY

The discussion centers on the concept of a perpetually driven electric car, exploring various energy recovery methods such as geared alternators on wheels, pinwheels for wind energy, and solar panels. While the idea of using regenerative braking to harness energy is valid, the forum emphasizes that achieving perpetual motion is impossible due to inherent energy losses from friction and electrical resistance. The topic is deemed inappropriate for further discussion, leading to the closure of the thread.

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.
