I rather like this idea... if I ever get around to building an electric car, I might try it out.

In fact, I might try it with air shocks in my Taco... As you hit bumps, the pressure in the shocks goes up... Tee off the inlet valve (where you pump them up) and put a small turbine in one line, with a check valve, into a bladder, then loop it back to the shock with another one-way flow check valve... as the pressure in the shock increases, it can expand out through the turbine line, into the bladder. Once the pressure decreases (shock rebound) the pressure in the bladder exceeds the shock, so it will equalize again, blowing back into the air shock.

Similarly, one could use hydraulic pistons with turbines, and vary the load on the turbines to adjust the suspension's stiffness and response. Imagine sports-car like handling from your old Volvo Wagon?
