This is in light of my last post. As I said, many biofuel developers are busy behind the wheel trying to create a viable jet fuel and there are a few airlines already working hard on making it happen. Heck, it would not only reduce carbon footprints but it would do just as much good to the bottom line. Gas prices, especially high end fuels, is going to rise, rise, rise over the next decade and the way out of that expense may very well run through a vegetable or tree farm.
For instance, Air New Zealand has tested a passenger jet powered by a second-generation biofuel derived from plants that do not compete with food crops. This is a much needed variation, no matter what the corn or peanut industries would like us to believe, as food crops are going to become harder and harder to sustain and world food supplies are going to dwindle over the next century. Air New Zealand ran the flight to and from Auckland International Airport using a 50-50 mix of standard A1 jet fuel and oil from Jatropha trees in one of its four engines. Although this is not the ideal ending to the concept, the best solution would be to run on NO jet fuel at all, this is a good beginning. The flight included a series of tests to assess how the biofuel-powered engine operated compared to the ones running on kerosene at different speeds and at different stages of a normal flight.
