New Process Takes Energy From Coal Without Burning It
rtoz writes "Ohio State students have come up with a scaled-down version of a power plant combustion system with a unique experimental design--one that chemically converts coal to heat while capturing 99 percent of the carbon dioxide produced in the reaction. Typical coal-fired power plants burn coal to heat water to make steam, which turns the turbines that produce electricity. In chemical looping, the coal isn't burned with fire, but instead chemically combusted in a sealed chamber so that it doesn't pollute the air. This new technology, called coal-direct chemical looping, was pioneered by Liang-Shih Fan, professor of chemical and biomolecular engineering and director of Ohio State's Clean Coal Research Laboratory."

The coal and oil companies have spent in the United States alone a half a billion dollars in the first eight months of this year promoting a lie that there is such a thing as "clean coal." Clean coal's like healthy cigarettes -- it does not exist. It could theoretically exist. The only demonstration plant was canceled. How many, how many such plants are there? Zero. How many blueprints? Zero.
