I saw a recent article that Audi would prepare an energy recovery suspension. Called "e-rots", these would be rotary jacks.
What is interesting is that they give the orders of magnitude of the recoverable powers ... we are in the sixteenth ...
100W on a slightly uneven road, the maximum would be 600W on a very bumpy road ... and 3W (!!) on a "smooth" highway.

Be aware that a cruising car (90-100 km / h) consumes 10 000 to 20 000 W. I let you calculate the possible gain.
