I won't tell the Deluce family that, but I'm sure it's very true.
You talk about biofuels as one of the ways that may be utilized going forward. In fact, in some respects it's already being used. In my own community of London, Ontario, through Western—our university—we have the Institute for Chemicals and Fuels from Alternative Resources. They will take leaves, bark, and various things and they have two byproducts: one is basically fertilizer for soil; the other is jet fuel. Who knew? They are going through this process now, which is quite amazing.
When we've had representatives from the transportation industry, particularly around various fuels and the automobile, one thing they've said is that going forward there are two ways you save money. One is related to the type of fuel and the other to the weight of the vehicle. I'm sure historically you've seen those developments over time.
If I can ask you to be a futurist rather than an economist, where do you see the greatest economy associated with those developments, going forward?
