Miracles of Engineering in Peru: Drinking Water Out of a Billboard. Finally, a Billboard That Creates Drinkable Water Out of Thin Air. No really, it’s a billboard that can generate up to 26 gallons of water a day from nothing but air. The billboard has already produced about 2,496.42 gallons of drinking water in a 3 month period, an amount that equals the water consumption of hundreds of families per month.
“They could put this in different places. If possible in every village, in each town, so water is generated through these billboards. The water really gives us life,” added Quilca.
