“The fresh, pure water on offer along a busy road in this dusty town some 90 kilometers (55 miles) south of Lima, has been extracted, as if by magic, from the humid air.  Within the enormous, raised, double-paneled billboard inviting all takers is concealed a tube, wires and mechanical equipment that draws the water from the air and purifies it.  Inhabitants from far and wide who flock here toting liter bottles and buckets say this purified water is a wonderful alternative to the stagnant well water that used to be the only water source for many in this town.”
