Here is something I read on a Wiki article: "Scientists are investigating ways to harness the wind energy within the jet stream. According to one estimate, of the potential wind energy in the jet stream, only 1 percent would be needed to meet the world's current energy needs. The required technology would reportedly take 10–20 years to develop. There are two major scientific articles about jet stream power. Archer & Caldeira claim that the jet streams can generate the total power of 1700 TW, and that the climatic impact will be negligible. Miller, Gans, & Kleidonclaim that the jet streams can generate the total power of only 7.5 TW, and that the climatic impact will be catastrophic." So, bottom line, can the kinetic energy of these fast moving winds(about 110 to 184 km/h) in the upper atmosphere(round about >12 km) be in any way harnessed? If so, how?
