Tiira, The Pyramid, Daisy, OTS and SuperTurbine ™ have a family resemblance. These tilted torque transfer turbines could be completed by the device represented on Makani patent US7847426B1, figures 1A, 1B, 2 and 4.
I wonder if a simpler control could be achieved by developing Daisy with rigid blades, keeping only the rotor and the tethers as airborne elements.
Otherwise some first tests could be achieved by using fast semi-rigid kites like the Celerator which is a really fast kite that I flew.
