By harvesting the energy wasted by ordinary shock absorbers, a prototype device aims to take over much of the work now performed by alternators. In hybrid vehicles, the GenShock also could boost mileage by 10 percent. The GenShock design has been patented by Massachusetts Institute of Technology (MIT) students who formed a startup, Levant Power Corp., that is targeting heavy vehicles like Humvees and AM General's proposed Joint Light Tactical Vehicle. In a marriage of electrical and mechanical engineering, GenShock absorbers compress hydraulic fluid as they damp the vertical motion of the shock, generating up to 1 kilowatt per shock. An active suspension system then converts into electricity the combined hydraulic pressure from all the shocks using a centralized generator.
