The University of Engineering and Technology, UTEC, was looking for some way to wow students for their upcoming semester.  They went to Lima, Peru, where people have been suffering from a lack of water, since they receive little rain.  They have about 98% humidity, but it doesn't rain much.  The planet is weird.

The billboard takes the humidity from the air, and turns it into drinking water!  They've already produced thousands of liters of water for the area, helping hundreds of families in the area!  Just from a billboard standing there!

That's a cool use of technology.
