I'd like to just copy the bar graphs in this "white paper" showing the cost of producing desal water now running for larger projects as low as about 55 cents per cubic meter of water. A gallon is about 4 liters, with a liter being the volume of water contained by a cube ten centimeters (0.1m) on an edge. A cubic meter is one thousand liters or 250 gallons. Anyone look at their water bill lately. . . . you are billed I think in units of 100 gallons. Yah, the costs in some areas are less than 11 cents per unit that would be the cost of desal produced from seawater. Anybody got a water bill from a city in California?
