What's the story with kite-reeling?

Pierre: I’m not convinced that even if you had some free (zero cost) source of “pull”, on the ground, that “reeling” would form an economical electricity-generation solution.

It can be right, but other operation modes look to be barely better. AWES could compensate bad generation means with large swept areas in high altitude.
