excerpt: "Archer and Caldeira looked at both wind speed and air density at different altitudes, concluding that extraordinary amounts of energy exist above Japan, eastern China, the eastern coast of the U.S., southern Australia and north-eastern Africa. Kite-driven generators Average wind power densities in these locales "are greater than 10 kilowatts per square metre. This is unthinkable near the ground, where even the best locations have usually less than one kilowatt per square metre," said Archer. New York clocked up a whopping wind power density of 16 kilowatts per square metre, the study found." <more>
