Bird-friendly glass designed with help from spiders
There's such a thing as bird friendly glass. A German company called Arnold Glas makes Ornilux, and recently collected an international design award for its spider-web inspired product.
Estimates are that more than 100 million birds die every year in the United States from collisions with windows. The number is about 250,000 a day in Europe, according to Arnold Glas. A special ultraviolet reflective coating makes the Ornilux glass visible to birds, but doesn't obstruct the view for us humans, according to an Aug. 22 Treehugger report.
