The Development of Ecologically Sound Jet Fuel
Roland Piquepaille writes "Researchers at Princeton University are currently working on two projects to reduce jet travel's role in global warming. The first one, a major project funded by the U.S. Air Force with $7.5 million, is focused on developing computational models that accurately simulate the burning of jet fuel, a complex process not well understood today. The second one, funded by NetJets, a company providing business jets, will help to develop new jet fuels with near-zero net greenhouse gas emissions."
Unless this fuel meets the exact spec of existing jet fuel.
Each aircraft type will have to be tested and certificated for use with this fuel.
This is very, very costly and time consuming.
