Some of the technology breakthroughs will come. We don't know when they'll come. Companies are always working on the type of process change DuPont did in making nylon. They make huge profits when they come through. They're great energy efficiency breakthroughs.
When will they come? It's hard to predict. That's why the issues of short-, medium-, and long-term approaches are so important to this, and why it's so important to have focused improvement on new investments in capital stock turnover. We could also do continuous improvement, and that's the kind of 1% a year we do, absent the major technology breakthroughs.
So it happens in our sector. We're looking at how we can capture carbon, as are other sectors, and that will come on board when it's ready. Maybe the technology investment fund that was part of the previous government's proposal--I understand it's also part of the current government's proposal--can be helpful in that. But it's hard to predict exactly when these things will come on board. They involve research and development, and we have to take a long-term, a medium-term, and a short-term perspective.
