In May, a team of British scientists abruptly canceled an experiment they
had been planning for nearly two years. The Stratospheric Particle

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

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.

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
