We constantly look for better ways to heat, but it's just very difficult in the winters here when it goes down to -40°C at times. We are unique in terms of the coldness we have to deal with. We'll look at any innovation, though. I would have a whole different attitude towards the carbon tax if a percentage of that went strictly to innovation instead of going to other people. If it went to innovation to fix some of these problems and get to a more zero base, we would embrace that very quickly.
I don't know what else to say about it. People have talked, also, about biomass and stuff. There's a huge infrastructure you need with that, and if you need digesters and things like that, our operations in Canada are not big enough for that, and you won't get the heat you need. We're constantly looking.
