Mike is right, in terms of the motivation behind a producer. A producer will sell and produce what is at the highest cost, so it needs to be realistic, whether it's a new crop or an existing crop specifically designed for the biofuels market. It all comes down to price. In terms of new crops, there has been a lot of investigation over time with various kinds of oils and products that can be used. That investment needs to continue, in order to be able to open up the possibilities. Economics will take care of the introduction itself.
