8. Here is a 2009 study on the topic

Global Assessment of High-Altitude Wind Power
Cristina L. Archer 1,* and Ken Caldeira 2

http://www.mdpi.com/1996-1073/2/2/307/pdf

It will be interesting to see how the discussion proceeds. A claim similar to that in the OP (but concerning low-level wind) came out of MIT a couple of years ago and it turned out that the resolution of the modeling assumed turbines occupied all space in each grid cell examined, so its conclusion was not able to be substantiated.
