To my understanding, I don't think so. I'm not aware of that. The dryer that I have was originally propane—and this is nothing against Mr. Kelly's product—but we have a pretty good natural gas distribution system, and I was able to tap into that. It's very close to our farm. It is very convenient because natural gas does not need to be delivered by truck. It just comes in the pipelines, so that's good.
I'll go back to your question about diesel fuel. I'm not aware.... That's not to say they don't exist. However, I would suggest that the vast majority are propane-powered, are propane-fired or use natural gas. I have heard of people trying to do grain drying using, well, straw—I guess it would come under the classification of a biomass—but I think it would just be a horrific amount of crop residue that you would have to burn in some kind of a container to contain the heat. I applaud the effort, but I don't think it would be very good.
