This story seems like what Mr. W. styles "
oughta be true," but for what it's worth nonetheless:
stained glass is good for you.
The glaziers who created gold-painted stained glass windows for mediaeval churches in Europe… developed a solar-powered nanotech air-purification system.
According to Zhu Huai Yong, an associate professor at Queensland
University of Technology in Australia, the gold paint used in
mediaeval-era stained glass windows purified the air when heated by sunlight.
For centuries people appreciated only the beautiful works of art,
and long life of the colors, but little did they realize that these
works of art are also, in modern language, photocatalytic air purifier with nanostructured gold catalyst, said Zhu in a statement.
Any excuse to run a picture.
