Indeed if they were working properly, the Power to space use ratio would be better: for a dreamed AWES in an ideal world, no problem of takeoff and landing, no crash risk with computerized system, no wear kite in spite of reel-in and out phases, and so on…
Crosswind AWES can fly slower or even in stationary flight, removing overspeed issue.
On a general point, AWES will never be able to compete with HAWT on a same market segment, for reasons that have been explained a thousand times: lower reliability, efficiency, power to space use ratio…
On the other hand, its only chance remains to try to exploit the high altitude winds and sweeping much more space. But for that other designs are required.
