This story from Lima, Peru is truly cool.  Faced with a city with almost no rain, 98% humidity and a water shortage Peru’s University of Engineering and Technology literally made water out of thin (albeit humid) air.  They put up a billboard that captured humidity from the air and turned it into water by reverse osmosis.  For more details click here and check out the video below.

This could be panacea for water starved regions with sufficient humidity to generate water.  However, before mass implementation of such techniques, studies should be performed to discover the impact on weather and rain patterns in other regions.  Robbing Peter to pay Paul could merely shift the water shortage elsewhere.  Yet this is a truly innovative solution that could help combat an issue that will cause more strife this century than oil – water shortages.
