With all of the water we have in the world, only 2% of it is fresh water. To make matters worse, only one-forth of all fresh water is accessible to humans. Until now, the entire human race has survived on 0.5% of the available water on earth. But that’s about to change.
We are seeing a fast growing trend towards harvesting water from the atmosphere, something our ancestors first began working on centuries ago. People in the Middle East and Europe devised the original air-well systems over 2,000 years ago. Later the Incas were able to sustain their culture above rain line by collecting dew and channeling it into cisterns for later use. Even though these techniques have been around for a long time, technology in this area has recently taken a quantum leap forward, and many are beginning to think in terms of houses that generate their own water supply, self-irrigating crops, and even “waterless” cities.
A new breed of inventors has emerged to tackle this exact problem. Using solar, wind, and other forms of passive energy, our future water networks will be operate with far more efficiency and convenience than anything imaginable today.
