If all of the water in the world could be poured into one bucket, only one teaspoon of that water would be drinkable. In fact, the scarcity of clean drinking water is responsible for the deaths of 2,000 children a day; dehydration and poor sanitation. In the US, nearly 50% of water usage is devoted to power generation, a third to agriculture, and appropriately 5% for industrial purposes. The majority of the publicly or privately funded research on water technologies has been conducted to satisfy standards for municipal needs (11% of US water use)1. Although research is being conducted to b...
