Drs. Norbert Mueller, Tonghun Lee, Patrick Kwon, and Indrek Wichman, Professors in Mechanical Engineering, in collaboration with Electrical Engineering Professors Elias Strangas and Fang Peng are the recipients of a two-year, $2.5 million grant from the U.S. Department of Energy's Advanced Research Projects Agency.  The engine, as part of a serial hybrid vehicle, could cut fuel consumption by 80% and carbon dioxide emissions by over 90% compared to a conventional engine.  The wave disc engine would also be smaller, light and cheaper to produce than a traditional car engine.  This grant is the largest amount of federal stimulus money that MSU has received to date.
