Did I miss a segment of that article on energy storage? One of the most difficult components of making wind energy practical on a large scale for any grid is it's lack of predictability. I suspect that things are somewhat more predictable at higher altitudes but not so much so that it mitigates the challenge of having a turbine that isn't necessarily going to be spinning when you need it.
