Scientists wary of shale oil and gas as US energy salvation

After 10 years of production, shale gas in the United States cannot be considered commercially viable, according to several scientists presenting at the Geological Society of America meeting in Denver on Monday. They argue that while the use of hydraulic fracturing and horizontal drilling for “tight oil” is an important contributor to U.S. energy supply, it is not going to result in long-term sustainable production or allow the U.S. to become a net oil exporter. Charles A.S. Hall, A.S. Hall, professor…

Creating Inexpensive Hydrogen Fuel From Water

A new, relatively inexpensive means of producing hydrogen fuel from water — relying on charcoal powder and lasers — has now been created by researchers. The new method owes its relative affordability to the cheaper materials involved — charcoal and carbon powder rather than expensive catalysts or high-power electric currents. As of now, though, the technique is only proven on very small scales — until the method is modified to produce larger quantities of hydrogen, applications will be limited. The…
