How does it work? He did away with piston skirts here and bearings there, a configuration that produces 35% less friction than a regular engine. It will work in trains, tractors, trucks, automobiles, and other fuel-burning vehicles, with diesel and spark ignition engines of four or more cylinders.
Moving parts mean friction; friction means a drag on engine efficiency. Five years ago independent Austin, Texas, inventor Mike Brickley took this on as a challenge. He created and patented a car engine that gets a 15% to 20% increase in fuel efficiency and a 15% to 20% decrease in CO2 emissions, and he was recently was featured in the New York Times in the 2008 Year of Ideas issue as a result.
