Audi has been developing a suspension system that can generate electricity for your car.
Called the eROT system, Audi wants to reuse the energy that is generated from the suspensions’ constant kinetic motion. eROT involves the usage of lever arms that are attached to both an alternator and the car’s suspension system.
As the car moves around, the suspension will be constant moving up and down, causing the lever to move the alternator, which will in turn create some electrical power. Essentially this is an electromechanical rotary damper that can generate enough power for a 48 volt lithium-ion battery.

The eROT also redesigns the suspension system in a horizontal design as opposed to the traditional vertical setup. This allows for improved damping capabilities since less pressure is applied to the suspension springs. In addition the horizontal design also provides more interior space for the car.
This is not the first time people have used the suspension system to generate electrical power. Back in 2009, a team of Massachusetts Institute of Technology (MIT) undergraduates created a system that uses fluid to push a turbine attached to a generator to create electricity.
