Yes, I think we've seen more options going on right now, like geothermal and things like that. We have buildings heated by solar and some are using wind-power electricity as well to serve those buildings.
For the grain drying, our producers—our farmers—put a lot of grain through. These are quite big structures and dry a lot of grain. What a farmer will harvest during the daytime will quite often be redried by his facility during the night, so in the morning these structures are ready to be filled again. A huge volume goes through. There's nothing out there for our farmers that is affordable. To convert is simply.... If that was available, I'm sure our farmers would be looking at those kinds of options.
