If only my home was self-cleaning
Associated Press has a story out of Stockholm, Sweden, about nanotech advances that could lead to self-cleaning buildings, roads and other infrastructure.
“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 article states.
Example given: Concrete walls that break down vehicle exhaust pollution in road tunnels.
