I would have to say that I'm not aware of any. As I said in my testimony, I did an upgrade on my dryer a number of years ago, and as far as I know, I am as current, if you will, or as up-to-date as possible with the latest technology on my dryer for efficiency. There's just nothing else available.
I hope I farm long enough to see if we have something different. I don't know if we will come up with something different, but if we do, if it works, if it's efficient and if it's cost-effective, I'm sure we would adopt that.
