Eating Pollution, Part 2

Just days after the Dutch University of Twente announced it's breakthrough sidewalk paver that eats pollution, the Spanish have gone one step further with a street asphalt material that can capture up to 90 percent of nitrogen oxide pollution on a sunny day. "...this method apparently uses a layer of a product called "noxer" that's affixed to regular asphalt which, again, produces a reaction that turns the captured nitrogen oxide into a more harmless material that can be washed away whenever it rains." Sadly, LA's pollution eaters are stuck in schools next to freeways. [Engadget]
