Billboards, we all drive by them every single day but what good are they really?  Some might catch your eye and notify you of a sale or service that you might try... if you remember the name, number or website.  In reality, billboards are just more visual noise that we are bombarded with on a daily basis - until you see this one.

The University of Engineering and Technology of Peru (UTEC), which was looking for something splashy to kick off its application period for 2013 enrollment. Turned to ad agency Mayo DraftFCB, which struck on the idea of a billboard that would convert Lima's H2O-saturated air into potable water. And then UTEC actually built one.

Why can't all billboards be this useful?

The billboard pictured here is real, it's located in Lima, Peru, and it produces around 100 liters of water a day (about 26 gallons) from nothing more than humidity, a basic filtration system and a little gravitational ingenuity.
