Did you know that every time you flush in a public restroom—you do flush, don't you? Cause that big mint ain't going to cover up your Margarita-infused asparagus pee—you waste about a gallon of water? The goal of this project, thought up at the Kaiser Permanente French Campus Facility in San Francisco, is to create a flushless urinal system. The urinal is made of poreless ceramic so your whizz goes straight into a little hole where it is covered by some sort of lighter-than-pee liquid where it is later pumped away. Now, obviously, you have a healthy dose of pee waiting behind the wall at your local Denny's, but we're saving the earth, here, people.
