The Carnegie Institution and California State University have published new research that shows that high altitude winds could power the world 100 times and the greatest sources of wind energy are found above some of the world's largest population centers in East Asia, the eastern U.S., southern Australia and north-eastern Africa.
The study looked at measurements compiled over 28 years by the viagra paypal National Center for Environmental Prediction and the DOE. What resulted is the first high-altitude wind energy maps that plot wind energy density (kW/m2) around the globe. The high population areas have an average high-altitude wind energy density of 10kW/m2 compared to the average ground level wind energy density of less than 1kW/m2. New York City has the highest wind energy density of a major city at 16kW/m2.
Researchers say the best place to capture this great source of energy is up near the jet streams at around 30,000 feet. The wind is 10 times faster than on the visit our site order viagra ground there and also blows much more steadily, making it ideal for wind power generation. As exciting as that is, it presents the large challenge of figuring out how to capture wind energy that high above the ground. One idea that has been proposed is high-flying kite turbines that are tethered to the ground. The current designs could potentially generate 40 MW of electricity and transmit it back down the tether.
Beyond just building the technology to harness those high winds, even the most steady winds stop blowing occasionally - about five percent of the time - so energy storage would also be a major factor in this type of order levitra from canada renewable energy.
