Shocking discovery harnesses free energy

Some smart MIT students (redundant, I know) who have no vested interest in old technology have come up with an ingenius way, perhaps a genius way, to generate more energy in a moving vehicle. A shock absorber system that generates electricity frlom every bump! Why didn't I think of that? While current electric hybrid vehicles use braking to produce power, none have tried to harness the ups and downs of the shock system. Folks on bumpy roads, gravel or potholes, are really gonna love this.
