Imagine there is a supercharger at the top of the hill. And a Tesla is charging there.
So pushing current into the car, is electrons dropping from high to low (potential energy gain ~ gravity)
The Tesla is now 50% charged, and starts rolling down the hill. And due to regen, it ends with 75% charge (lets say).
Ignoring transmission losses, battery losses, did we just create energy?
