As I was emptying the try full of water from my dehumidifier downstairs I thought, "Pulling water out of thin it possible to make clean drinking water out of this?" The answer is yes. The billboard you see above produces about 26 gallons of water a day from nothing more than humidity, a basic filtration system and a little gravitational ingenuity. Wow!

What would be even more amazing would be if it was entirely self-sufficient, but it's not. The billboard needs electricity to power the devices that make up the billboard's inverse osmosis filtration system.

According to

The water is then transported through small ducts to a central holding tank at the billboard's base, where you'll find — what else? — a water faucet. According to Mayo DraftFCB, the billboard has already produced 9,450 liters of water (about 2,500 gallons) in just three months, which it says equals the water consumption of "hundreds of families per month." Just imagine what dozens, hundreds or even thousands of these things, strategically placed in the city itself or outlying villages, might do.

Just think of what we could accomplish in any number of deserts and other troubled spots around the world that need portable water. Could this be the solution?
