Researchers look for alternative jet fuels

I know we have all heard this a time or two. Gas prices are going up and we are looking for alternative ways. We have found some alternative ways, but airplanes are a little unlucky in that situation. Researchers are trying to find an alternative fuel for jet engines. And it is hard to find when the alternative fuel, biodiesel fuel, freeze 35,000 feet in the air. And even if scientists can figure out a way to not let this fuel freeze, how is there enough farmland to be able to make all this fuel for cars and jet engines. A U.S. Department of Agriculture chemical engineer, Robert Dunn, says, "The main challenge right now is economics, even though the price of petroleum is going up, biodiesel is still at a disadvantage economically. It simply costs more to produce."
They are trying to come up with so many different ideas to try and lower to cost of fuel to run these jet engines. A couple ways is: biodiesel, liquid hydrogen, and biodiesel mixed with regular fuel. The one bad thing about liquid hydrogen would be that it could blow up on board and there would be troubles with the storage of it. Really all they are looking for now is something to look forward to in the future, and it is going to be a long while before anything is really completely figured out.
