Greening Cities Through the Power of Public Urination

Ever walk down the street and notice a sad, brownish scrub of a plant? Just pee on it!

That's the joyful message from a team of San Francisco designers who want to nourish the city's plant life with a reservoir of citizen urine. This unusual plan came about after they connected the facts that 1) pee is loaded with chemicals like nitrogen that help plants grow 2) people are just giving it away all over dumpsters and alley walls. Since we can't have that, they fabricated a public urinal called the PPlanter that transforms steaming whizz into precious, golden fertilizer.
