According to Farm Press, researchers at the University of Georgia are working to fix this problem. They see the answer in a peanut variety that would be grown specifically for biodiesel production. Their primary goals are that they be non-edible, high in oil and cheaper to grow than a conventional peanut. If they can meet these requirements, they would not have to compete with the world market and biodiesel will be one step closer to becoming what Phillip Badger, president of General Bioenergy, calls a part of the "silver buckshot" solution alongside ethanol.
