Roto-Kite project
• A simple project characterized by a few kg of fabric and cables, a balloon to keep the
system in height even in the absence of wind, a ground-based generator
• The rotation produces a lifting force which is transmitted to the ground by the bound
cable and transformed into electrical energy
• The rotation principle and some technical aspects of flight control are commonly used in
helicopter flight technology
• The size of the rotor can be modified to adapt to the intensity of the wind
So this system looks to be for creating electricity. Apart from that, I think that the central aerostat can lead to a maintenance problem more than an automated piloting system, especially since a computerized control will always be necessary, even if the AWES produces in passive mode. So I can prefer a low radius loop system with only one controlled kite.
