Smart process cleans up contaminated water

A smart material identifies and destroys toxic pollutants in water. When exposed to the offending molecules, tiny light-emitting zinc oxide particles glow dimly, burn them up, and glow brightly to show they've finished.

So the other day we put lasers in the exhaust pipe and now we get more light from pollutants. Looks like those amateur astronomers who do all the complaining about light pollution have barely seen the tip of the iceberg.
