Energy harvesting shock absorbers~ At SUNY Stony Brook, mechanical engineering professor Lei Zuo invented a shock absorber that converts the kinetic energy from vibrations into electricity.Zuo took that idea a step further, and designed a system of gears that collects the energy of irregular motion to ultimately produce electricity. He calls the device a mechanical motion rectifier, or MMR.Generating electricity reduces the load on the alternator and engine, which notonly drive the car but also power accessories such as the windshield wipers and radio. Generally, a regenerative suspension system could supply anywhere from 100 to 400 watts. A typical car might draw 200 to 300 watts depending on whether the lights or the radio are on.
