My explanation is quite a simple one, and that is that if we went to the super-critical technology at that time, which was the existing best available technology economically achievable under American definitions, then that would only have a lifetime of eight to ten years before the new clean coal technology would be available. If that then became the regulatory standard, you'd be in a situation such that instead of having a 40-year lifetime for that technology, you would have only a ten-year lifetime.
I say that in the context, especially, of which I was testifying before the U.S. Senate at that time, and of some of the regulatory aspects of certain states that were being proposed at that time.
