'Before the dawn of civilization, there were 326 million trillion gallons of water on the Earth. Unlike other natural resources, we cannot run out of water. With over 6 million people, we still have 326 million trillion gallons of water." GOOD magazine, Summer 2009
" If all Earth's water fit in a gallon jug, available freshwater would equal just over a tablespoon - less than half of 1 percent of the total. About 97 percent of the planet's water is seawater; another 2 percent is locked in icecaps and glaciers. Vast reserves of freshwater lie under the Earth's surface, but much of it is too deep to economically tap" - National Geographic Special Edition: Water -The Chaos of Supply, November 1993
To solve our Water Crisis, we need innovations that increase FRESHWATER supply while increasing sustainability and resilience of Nature's ecosystems --- We cannot just rely on using less water --- AIR can be a new source of free fresh drinking water everywhere on Earth. As we are not likely to ever have unlimited cheap power, this blog focuses on water-in-air and on insights gained from the world of humans, plants, animals & insects to engineer a BIOLOGICAL way to EXTRACT WATER FROM AIR
