I call complete and utter BS, and have to read no further. What an idiot.

"While oil shale is found in many places worldwide, by far the largest deposits in the world are found in the United States in the Green River Formation, which covers portions of Colorado, Utah, and Wyoming. Estimates of the oil resource in place within the Green River Formation range from 1.2 to 1.8 trillion barrels. Not all resources in place are recoverable; however, even a moderate estimate of 800 billion barrels of recoverable oil from oil shale in the Green River Formation is three times greater than the proven oil reserves of Saudi Arabia. Present U.S. demand for petroleum products is about 20 million barrels per day. If oil shale could be used to meet a quarter of that demand, the estimated 800 billion barrels of recoverable oil from the Green River Formation would last for more than 400 years."
The major problem with shale is the Democratic Congress insists we can't drill our way out of our dependency on foreign oil imports. The US Government (Congress) controls 72% of all U.S. oil shale acreage. Shale Oil - Democratic Congress = EOI (End of Imports)
