How to take the heat from shock absorbers and generate electricity from it?

[abray4]

I have been wondering how to do this, however I am not the smartest with cars components.

Could someone explain how the heat is produced and how it may be possible to take this heat and use it to generate electricity.

And / or the shaft movement...good thinking, hopefully it could be scaled enough to work.
Also ram air turbines as fitted to aircraft.

.... how it may be possible to take this heat and use it to generate electricity.

inefficiently
but damping forces made electromagnetically will efficiently generate electricity
(though not as efficiently as an engine-driven generator does when the engine is at partial power)

Would pizio work?

Make a coil out of a damper and use g-sensors to actively apply DC current to the coil to, dampen out the movement and generate some current to charge the battery.

I have investigated this before - dampers only dissipate an average of <50W of power across a lap. Not nearly enough to make any performance gains.

Except for the Merc rear dampers

In ATEGs, thermoelectric materials are packed between the hot-side and the cold-side heat exchangers. The thermoelectric materials are made up of p-type and n-type semiconductors, while the heat exchangers are metal plates with high thermal conductivity.[1]

The temperature difference between the two surfaces of the thermoelectric module(s) generates electricity using the Seebeck Effect. When hot exhaust from the engine passes through an exhaust ATEG, the charge carriers of the semiconductors within the generator diffuse from the hot-side heat exchanger to the cold-side exchanger. The build-up of charge carriers results in a net charge, producing an electrostatic potential while the heat transfer drives a current.[2] With exhaust temperatures of 700 °C (≈1300 °F) or more, the temperature difference between exhaust gas on the hot side and coolant on the cold side is several hundred degrees.[3] This temperature difference is capable of generating 500-750 W of electricity.
Currently, ATEGs are about 5% efficient. However, advancements in thin-film and quantum well technologies could increase efficiency up to 15% in the future
