Buildings that eat smog? Alcoa, a maker of aluminum products, introduced an architectural panel Thursday that it says not only cleans itself but also the air around it.
The aluminum panel has a titanium dioxide coating that, when combined with sunlight, acts as a catalyst to break down pollutants such as smog into harmless matter that rain washes away.
"It could have a significant impact" if enough buildings use the product, says Craig Belnap, president of Alcoa Architectural Products. The company says 10,000 square feet of its panels have the air-cleansing power of about 80 trees.
