The weight of the on board capacitors would in itself be an energy

And how do they get up to speed - magic pixie beans?


Stupid boy. You don't get anything for nothing.
But storing kinetic energy is far more efficient than charging/
discharging batteries.

Kinetic energy stored as vehicle momentum is of no use for accelerating
the vehicle. At the time you need it it isn't there.

It's also of no use for climbing hills - the extra weight exactly cancels
out the extra KE.

Nonsense. Heavy trucks roll down hills and up the other side very well.
