I can't give you an absolute number on that, no, but I can give you some feel. Again, I want to come back and say that I'm arguing for technological innovation as opposed to science and technology. There is a bit of a difference.
David Keith is one of the foremost people in the area of greenhouse gas emissions and concerns in Canada, in my opinion. You may have heard from him in this committee. If not, I would recommend him as somebody from whom you might want to hear. He is an academic from the University of Calgary who will tend to speak more toward the CO2 control side. He will tell you he is tired and fed up with white lab coats and the lab bench, that it's time to get on and do the pilot plant and demonstration stuff.
To more specifically address your question, the issue is that as you enter into that middle stage of the supply chain that I showed you, things get expensive. You're talking about $10 million pilot plants and you're talking about $100 million demonstration plants. In my opinion, the only way to do this is through a risk-shared exercise between all levels of government and the private sector. No one alone will bring that about.
We need to see some new paradigm of crossing that gap in the middle of commercialization. The technology is there, but there isn't the business climate for the private sector to put it in place, and there isn't the money in the middle stage to get it developed, for the most part.
