Liquified coal, a.k.a., coal to liquid transpo fuel, CTL, produces twice the carbon emissions that gasoline produces, so, this writer says that those using it, (including the U.S. Air Force, though this writer doesn't name the world's big CTL users), will need to buy carbon off-set credits to make up for it. http://tinyurl.com/cv2n79 South Africa is way out in the lead in CTL production. The U.S. Air Force buys a great deal of it from the corporation described here, to power its operations in Africa. The Office of Surface Mining, within the Interior Department headed by Ken Salazar, has given the Peabody Coal Mine, in the native Four Corners a renewed "life of mine" lease, but there are no plans to re-open the Mojave Generation Station there, so it seems most likely that this is about the plan to have the whole U.S. Air Force running on CTL by 2011. I'm not yet sure whether they plan to run on 100% CTL or some kind of mix, but the B-1 bomber and other jet fighter bombers are running on CTL or set to. I know that printing a real letter, finding an envelope, and putting a stamp on it is an ordeal in these digital days, but, the Native American Black Mesa Water Coalition has asked us to send letters to Ken Salazar, head of the Interior Dept., asking him to cancel the renewal of Peabody Coal's life-of-mine coal mining lease at Big Mountain/Black Mesa. It seems that they're having trouble finding an e-mail address for Ken Salazar, so here's the postal address: Ken Salazar United States Secretary of the Interior Department of the Interior 1849 C Street, N.W. Washington DC 20240
