 | by Dave Levitan, Yale Environment 360. An article relevant to GSS Energy Use chapter 10. Excerpt: With conventional wind power facing a litany of obstacles — intermittency, space requirements, not-in-my-backyard complaints — pushing wind power up into the atmosphere could take a lot of uncertainty out of the equation. And despite a host of technical and regulatory challenges, a growing number of small companies are working hard to get up there within the next few years, with numerous designs and ideas aimed at harvesting wind power high in the sky…When it comes to really taking advantage of higher altitude wind…reaching as high as the jet stream is the real prize. The power density in Earth’s jet streams is around 100 times that of sunlight hitting a standard photovoltaic cell…But the differences in engineering requirements between flying a device at 1,000 feet and at five or six miles are enormous....
