First of all, we know that there are inefficient and more efficient grain dryers, and already farmers are investing in the more efficient ones.
We did a study called “Zeroing in on Emissions”. We looked across the economy at studies on how we can decarbonize as a result of carbon prices. What we're talking about in grain drying is a low-temperature heat, compared with the very high-temperature heat that industrial processing may need. That's a perfect application for heat pumps.
There are some heat pump dryers that are already available on the market. I did some reading on this to look into this very question. By having a price signal, this will be incentivized. Different approaches will be developed and—
