A car wastes energy almost continuously. Whether it is running in first, second, or a higher gear, there is only one position of the accelerator that guarantees optimal performance. Accelerating a little less or a little bit more can cause considerable loss of energy. John Kessels has designed a way to save energy by enabling the car to achieve optimal engine performance more frequently. With a relatively small modification it is possible to reduce fuel consumption by 2.6%. Kessels obtained his doctorate from the Technical University Eindhoven (Netherlands) on Wednesday February 14, 2007.
