The Chem-Mod is one initiative at Mercury. If it works, some of the results they got, but their rates were too high to be commercially viable when they got it, but their results in a non-targeted mode were pretty outstanding on Mercury, and some really pretty awesome results on SO2. We want to be across the board in air pollution, and that would mean SOx which Chem-Mod might be able to do pretty well, and we have high expectations. If it’s not them, we are going to get somebody else. NOx, we’re already pretty good at that. Mercury, again we have some other initiatives on there too. Particulate, that’s where flue gas conditioning really helps in dramatically improving the performance of electrostatic precipitators and taking out particulates, and CO2, and in my own personal opinion, the carbon sequestration is going to fly. I don’t think the US will ever get over the liability issues around pumping vast quantities of CO2 underground, and I’m speaking as a person who probably launched the first of those kinds of initiatives back when I was with AEP, but I just think that that’s going to be a huge stumble block, but there are other ways, and we are working on other ways. If we really need them, we can come up with a way that can catch some substantial portion of carbon and bond it in a way that that could land filled or used in building materials without being deep underground sequestered, and our Fuel Chem programs. Santee Cooper, they got 1.5% efficiency improvement with our chemical, and with our consulting, we were able to help them achieve another 1.5% efficiency, so about 3% efficiency. The CO2 reduction is double the efficiency game as a rule of thumb, so they are going to drop their CO2 production rate by 6%, and they’re saving an incredible amount of money doing it. We think that’s a pretty strong case, and most of the studies that are being talked about in Congress are now recognizing that generation efficiency is the first and best step that could be done in this nation to reduce CO2 intensity and that’s what we want to do.
