Truly interesting, truly ingenious. This shock absorber has a unique feature: It can harvest energy from bumps in the road, convert them into electricity and thus increase the fuel efficiency by 1 to 8% !!! The design deservedly won recently the R&D 100 award.
|The new shock absorbers were designed by Professor Lei Zuo and graduate students Xiudong Tang and Zachary Brindak at the State University of New York (SUNY) at Stony Brook, with funding from the New York State Energy Research and Development Authority (NYSERDA). The development joins regenerative braking and other techniques that address the vast amount of energy wasted by vehicles. Although transportation accounts for 70% of oil consumption in the US, only 10-16% of the fuel energy is used to drive the car - to overcome road resistance and air drag. The rest is lost due to braking, vibrational energy dissipation, exhaust heat, and other inefficiencies.|
