There's a lot more work that needs to be done before even that decision can be made. The technology has to be there, first of all, and then the other questions—about environmental impacts, and as you mentioned, the energy one—obviously also need to be addressed, and the economic impact of it is also an important piece.
The association itself hasn't done any direct cost analysis, but there have been some draw-outs that, based on some of the numbers we've seen for smaller projects, have indicated that right now it wouldn't be economically feasible. But as I said, we're interested in continuing to look at the technology as it develops. Our companies are there and are part of that innovation, and we'll have to see as we work together into the future what the options are and what options become available.
