Is it possible to increase the efficiency of a propelled vehicle by extracting and using the energy from its own suspension system? If there is a propelled vehicle and it has a passive suspension system (Springs for example):
Is it possible to increase the efficiency of the system "propelled vehicle" by extracting energy from the suspension system with a recuperation device?
To give an example:
Lets assume a car with an electric motor and with springs as a suspension system. These springs should be connected with linear generators. Can I increase the efficiency of the car by extracting electrical power with the linear generators and by transmitting this energy to the electric motor?
Can I use the suspension system as a way of generating electrical power in a sense of "charging" the car batterie?
Many thanks in advance!
If I should edit my post in any way, please let me know, it's my first post here.
 A: No, where's why.
We imagine the simplest form of "bump capture": we imagine a tire on a car to be a cogged gearwheel with pointed teeth on it. when the cogwheel rolls into a pothole, the leading edge of the wheel rolls into the pothole and engages the lip of the pothole, so that as the wheel rolls across and down into the pothole, there is a force applied to the teeth on the wheel by the lip of the pothole which generates a torque which urges the wheel to rotate in its direction of travel.
But that force also points in a direction opposite to the car's direction of linear movement and thereby acts to slow the car down.
In this scenario, the effects cancel and this means that you cannot "harvest" suspension travel to produce a net force which assists the car in its forward motion.
A: What you are suggesting is "theoretically" possible. The suspension system of a car works by dissipating the "energy" of the shock through shock absorbers .
To quote wikipedia  '

It does this by converting the kinetic energy of the shock into
another form of energy (typically heat) which is then dissipated. Most
shock absorbers are a form of dashpot (a damper which resists motion
via viscous friction).

So, theoretically that energy could be somehow stored and harvested. But obviously, the engineering challenges and the state of the current technology mean that this is not a feasible option. The economics of it would not work.
But there is nothing preventing this theoretically speaking. Maybe, two hundred years from now, automobile technology would have advanced to such a level as to be able to utilise this.
An interesting technology along similar lines is the Kinetic Energy Recovery System ( KERS ) used in Formula 1 cars. It uses the energy that would have been dissipated as heat by the braking system , and stores it , so as to use it later for acceleration. 50 years ago, that might have sounded just as outlandish
