Out of Thin Air

water billboard

If you’ve ever though that there must be a better use for all the water in the air than making your hair frizzy, then you might be impressed by this idea for the next big thing. It’s a billboard that converts water from the air into something people can use for washing, cooking and even drinking.

It was created by an engineering school in Lima, Peru, which happens to be a very humid city that doesn’t receive much rain — meaning water is often in short supply there. The sign uses five generators and a process called reverse osmosis to do it. Pretty clever, right? But we want to here what you think. Are giant water-producing billboards the next big thing (at least in some parts of the world)? Vote in the poll and tell us what you think!
