Numerous companies are developing technologies, such as large kites, that can harvest wind energy up to a half-mile above ground. While still in its nascent stages, airborne wind power could potentially be used in remote locations or flying from barges far offshore.
One thing that I think could be a huge advantage for airborne wind energy collection is potentially lower energy cost for construction. A traditional wind turbine on land is big, and made of a range of energy intensive materials ranging from concrete and steel to aluminum and advanced composites. I imagine the additional material and transportation energy for scaling up a soft wing system is going to be a lot lower than what big turbines currently require. Plus, at the end of life, that means you have a lot less material you either need to ship out, and then figure out how to recycle or need to dispose of safely.
