It really depends on what year it is and how much drying.... Sometimes, you can almost take your beans in on your V-Bin, right into your bin, and it's hardly anything. A couple of falls ago, however, the corn was almost coming in like gum, in some cases. It really depends on the year.
That's why I say the use of propane or natural gas for drying is the most robust and efficient, in a time crunch. You have literally millions of dollars. I always say that, if you knew how much money it costs to make a dollar in agriculture, you'd never do it. However, people love to do it. It's been passed down through generations, and it's a struggle they love.
You can go to any farm in Huron County, Bruce County or anywhere else, and they're beautiful and well maintained. If they can make an investment in an innovation that reduces emissions and increases their profit margins, it's a no-brainer. They will do it.
