Self-Cleaning Buildings to Fight Smog

bryan8m writes "Using technology already available for self-cleaning windows and bathroom tiles, scientists hope to paint up cities with materials that dissolve and wash away pollutants when exposed to sun and rain. The idea: UV rays hitting the titanium dioxide coated cement and concrete trigger a catalytic reaction that destroys the molecules of pollutants, including nitrogen oxides."

Solar?

Wouldn't it be smarter to cover the buildings with solar panels, use that to power half the building and cut down of the amount of smog created by the power plants instead? Your car puts out NOTHING compared to a 250Mw coal plant.

Tarffic is the primary cause of pollution

Your car puts out NOTHING compared to a 250Mw coal plant.

Traffic is the primary cause of pollution in inhabited areas and car emissions are harder to control than those of a single 250 MW coal plant.
