Stony Brook University engineers have won a national award for an innovative energy harvester that has the potential to save millions of dollars in energy costs for railroads while reducing carbon dioxide emissions. The team’s work, “Mechanical Motion Rectifier (MMR) based Railroad Energy Harvester,” was awarded “Best Application of Energy Harvesting” at the Energy Harvesting and Storage USA 2012 conference, held in Washington, DC on November 7-8, 2012.

The Stony Brook team, led by Professor Lei Zuo and two graduate students Teng Lin and John Wang from the Department of Mechanical Engineering and Advanced Energy Research and Technology Center, developed a new type of energy harvester that converts the irregular, oscillatory motion of train-induced rail track vibrations into regular, unidirectional motion, in the same way that an electric voltage rectifier converts AC voltage into DC.
