Over 4 billion people live under conditions of severe water scarcity at least one month of the year. Over a billion people spend several hours a day searching for water, wasting precious time and putting them in frequent danger.
Some of this scarcity has led to violence and conflict, especially in Africa, Southern Asia and the Middle East. The Syrian conflict was triggered by a years-long drought.
So it would go a long way to achieving global peace and ending global poverty if we could give these people water without a lot of cost and trouble, and without a lot of infrastructure.
Like, say, pulling water right out of thin air.
That’s just what a new technology does. Called WEDEW (wood-to-energy deployed water), it is a collaboration between Skysource and ALL Power Labs and uses local biomass gasification (see diagram below). It’s versatile, self-contained and sustainable, converting biomass or agricultural waste into water and biochar, and sequestering would-be greenhouse gases in the ground.
Easier and cheaper than solar, and certainly better than diesel in all ways, biomass gasification is not ordinary combustion. It converts the biomass into biochar, hot humid air and electricity. Water is condensed out of the hot humid air in a process that mimics the way clouds are formed (the hot humid air hits cold air and forms droplets of rain) and stored in a tank inside the shipping container.
