Imagine A Bathroom That Cleans Itself

Considering scientists created a titanium dioxide coating for windows so they never need cleaning, it was only a matter of time before someone would test that very same substance on toilets.

Australian researchers are ironing out the process right now, but there's one big obstacle standing in the way: The absence of a source for ultraviolet sunlight that activates the nanoparticle compound so it will work on a toilet.

To the good, researchers have been able to kill common bathroom germs on glass in a bathroom with the titanium being activated by an indoor lamp.

Despite all the time and energy saved by such conveniences, I remain cautiously optimistic because this substance could turn out to be just one more form of pollution that could do more harm than good.
