Princeton Professor of Mechanical and Aerospace Engineering Fred Dryer has a lofty goal: end the nation's reliance on oil for jet travel. With potentially major benefits for energy security and the environment riding upon his success, Dryer is advancing the fundamental knowledge of jet fuels while developing practical, innovative energy sources. "In order to make alternative jet fuel sources feasible, they need to be compatible with petroleum and produce similar combustion performance," Dryer said. "This will only be possible if we fully understand how both petroleum and alternative fuels burn and design engines based on this fundamental knowledge."

The earth is growing warmer, thanks to elevated concentrations of greenhouse gases, and the vast majority of scientists now believe that human activity, especially the burning of fossil fuels, is primarily responsible. In June, the National Research Council concluded with a "high level of confidence" that the earth is warmer now than at any time since 1600 and, quite possibly, since 900, and this global rise in temperature is expected to accelerate if the emission of greenhouse gases such as carbon dioxide, methane, and nitrous oxide is not curtailed.
