This has to be my lest favorite green innovation. The concept is gross, and they always smell bad. The worst places are in high traffic areas like airports and museums. The smell of rancid urine hits you as soon as you walk in the bathroom. Maybe that can be said for many public bathrooms, but it's more likely to be present with waterless urinals. I went to the LACMA yesterday. Everything was spotless, including the bathrooms, but because of the waterless urinals, it smelled like a Flying J.
They are almost always accompanied by that self serving metal plaque boasting about how many thousands of gallons a single one of their waterless urinals saves a year. Many of the ones I have seen have that baby blue seashell logo in the well, which I assumed is what you aim for, but that has to be the worst place to aim for since it causes the most splashback. Not only do they smell, but they also trick you. If engineers can land a man on the moon, I don't see why they cant design a urinal that doesn't require so much finesse to prevent splashback.
