Mr. Chairman, thanks to the committee for allowing a couple of brief questions.
Along the line of questions of Mr. Bevington, the chart on page 5 graphically illustrates that when we talk about an east-west grid, people have often thought about transcontinental when we're actually talking about regionalized approaches. It seems to me that when you talk about NOx and SOx, and you talk about climate change with respect to carbon, the real concern on that chart is the generation mix reflecting the use of coal. I didn't hear any mention of the research and commercialization with respect to gasification of coal and the perspective with respect to that type of initiative. That's my question.
