When you talk to the experts about developing new technology to provide clean drinking water for the developing world, they'll tell you that — with four billion people making less than two dollars a day — there's no viable business model, no economic model, and no way to finance development costs. But the twenty-five poorest countries already spend twenty percent of their GDP on water. This twenty percent, about thirty cents, ain't much, but do the math again: four billion people spending thirty cents a day is a $1.2 billion market every day. It's $400 billion a year.
