Energy efficiency is something we look for. We look for efficiencies all the time. If it adds to our bottom line, we will look for that.
I've made a comment to people that.... I'm a little bit off-base here, but my combine is a very large piece of equipment and it has a big diesel engine in it. I said that I'd like to live long enough to see if we can come up with an alternative to a big diesel-powered engine. I'm not against that, but it has to be efficient. It has to be robust. It has to do the job. I'm sure, given enough time, we can figure that out. I don't see anything on the horizon, but I guess that's just my nature. I would be very interested to see if we could accomplish that because we need a lot of horsepower. It takes an awful lot of power.
