The other component of research would be taking a look at how to use existing agricultural waste to generate energy. That gets away from that whole food-versus-fuel debate. There's all kinds of product that is not even used. Farmers have agricultural waste that could be used for generating renewable energy. We have to look at ways to do that. That could be cellulosic technology for producing ethanol, or it could be looking at direct combustion of some products, provided it can be done without any air pollution issues. There's a whole series of issues on using that agricultural waste.
