The wind blowing through the streets of Manhattan couldn’t power the city, but wind machines placed thousands of feet above the city theoretically could.
The first rigorous, worldwide study of high-altitude wind power estimates that there is enough wind energy at altitudes of about 1,600 to 40,000 feet to meet global
electricity demand a hundred times over. The very best ground-based wind sites have a wind-power density of less than 1 kilowatt per square meter of area swept.
Up near the jet stream above New York, the wind power density can reach 16 kilowatts per square meter. The air up there is a vast potential reservoir of energy, if its intermittency can be overcome.
