Water from Thin Air

Google's Water Abundance XPRIZE is a $1.75 million competition. The winner is required to present a model that extracts 2,000 liters of water per day from the atmosphere using 100% renewable energy, at a cost of no more than 2 cents per liter." 

This 0.02 US$/ lt is the triple of desalination factory price. 

In principle, I am against these low tech decentralized solutions, designed for the Indian farmer. Like the toylike pedal pump proposed by the World Bank. Like the dried cowshit burning fireplace. Development people hate development, they hate modern technological economy, so the attraction of these paternalistic solutions never dies. They love to design ingenious toys for the stupid Indian and African farmers.
