Time for "urnals of the future," not old white dinosaurs of the past.
I liked the really old urnals that went down below the floor. They should be self flushing.
The biggest problems I have noticed with urnals, is some have a nasty habit of splashing back on you. Not what you want from a "public toilet." How are you going to get guys to use the urnal and stop going into some toilet stall, if they come away with a wet pants leg? And then the urine puddles on the floor are nasty. Is there something wrong with the urnal that is causing guys not to stand close enough to it, or are they just pigs?
Such problems could likely be much improved, by getting the angles right in the shape, and making sure it is mounted on the wall at the correct height.
What about the old urnals that go down below the floor? Aren't they better at not splashing back on you?
And greedy layoff-pushing, understaffing, corporations seem too cheap these days, to hire a janitor with enough hours, to keep public bathrooms from often being "nasty." So intelligent self-cleaning would seem a prime concern. And high reliabily and low-maintenance.
Have we seen much any improvements since we put a man on the moon some 50 years ago, and then did, in some areas, pretty much nothing since then? Surely there is much room for improvement in urnals and toilets. Not all this enviro-radical water-conserving nonsense, but in making them more attractive and effective in their basic function.
