Hi Mike, Could there be a method of selective filtering of coal-fired power stations, such that the cooling aerosol (or SO2 precursor) is allowed into the troposphere while the black carbon is removed? Cheers, John --- On Tue, Sep 11, 2012 at 7:15 PM, Mike MacCracken

As I understand it, the sulphur is mainly in the gas phase, whereas the BC is necessarily particulate. Therefore a cyclonic, electrostatic or conventional porous filter would probably do the trick. A On Sep 14, 2012 8:49 PM, John Nissen johnnissen2...@gmail.com wrote: Hi Mike, Could there

Hi John‹Regarding your query about changing power plant emissions, think back to the situation in the mid-20th century when all the black soot and ash was also coming out of power plants. Modern coal-fired power plants are tuned so as to not make much soot (it is wasted energy) and filter out most
