Billboard in Lima, Peru, creates 100 liters of water per day. Peru’s University of Engineering and Technology (UTEC) built an atmospheric water generator which creates fresh drinking water from the humidity in the air by condensing the humidity in the air into water. The system will generate approximately 100 liters of fresh clean drinking water for the town locals daily.
This system (as well as others) can be modified for off grid use, and powered by solar panels and wind power. The cost to build the system is about $1200, which in comparison to the life saving qualities of water, is well worth it.
You could also convert an old refrigerator and some copper pipe into an atmospheric water generator as well.
“…Internally, the panel consists of five devices that extract water vapour from the air using a condenser and filters…Water is stored in tanks at the top of the structure. Once filtered, it flows down a pipe connected to a tap, accessible to everybody…The internal system costs some US$1,200 (£790) to set up.” ~BBC
