My understanding based on reading their materials, is that it is very similar to conventional wind power. "High altitude" here refers to around 600m, which disappointed me because I thought it would be an army of devices flying autonomously in the stratosphere, (I kept reading to figure out how they got the power back to earth, at which point I found out they were tethered, and not flying in the stratosphere). So they should be very similar to wind power, except that they are tethered, rather than a turbine on a tower. I think the main issue is how much space they use on the ground, i.e. how much space around the tether point needs to be kept clear. EDIT: apparently even wind at 600m is better at ground level. Furthermore, the system is not really a "turbine sitting on a wing". The wing is the turbine blade. It moves in a circle, and the propellers on the wing draw the power from it's motion. It's really an amazing idea that, the kind of thing I wish I had thought of. I think this page has the most interesting information. http://www.makanipower.com/why-airborne-wind/ http://www.makanipower.com/why-airborne-wind/
