Ok, you're going to think this is the strangest cool technology blog to date.
In my travels, I visit a large number restrooms throughout the world. Recently, I've noticed a significant rollout of "waterless" urinals.
There must be some serious technology behind this, since no "input" plumbing is required at all. I often used the analogy that the paperless hospital is as likely as the paperless bathroom, until the Japanese introduced me to a paperless high-tech bathroom. Now we have the waterless bathroom.
How does it work? A special cartridge contains a lighter than water liquid that floats on top of urine, providing an airtight seal between the urinal and plumbing - no odor of urine or sewer gas enters the room. A typical office building can save millions of gallons of water every year by installing these units. No water supply is needed so the capital costs of installing them are less than standard fixtures.
An environmentally sound, waterless urinal that uses the physical properties of fluids to create an airtight seal and eliminate odors, saving millions of gallons of water per year. That's cool!
