The ratio is better than that. I'm looking at the big picture. In terms of total operating costs to our operation as we presented it, the infusion of energy is about 1.5% of total costs. In the case of ethanol, that is upwards of 10% to 12% of total costs. So the ratio is a lot better in biodiesel, converting canola oil to energy, for example, than it is converting cornstarch to energy.
