Below is a sketch representing an option to carry several small turbines without being too penalized by the mass of the bar, which is used only to maintain space between the two lines. The thin (for crosswind version) bar can be a thin foam Sharp rotor or a wing profile in order to generate a little additional lift. The tethers pass through the respective propellers of the turbines, a little like for Kiwee.
For large static versions, inflatable fatter shapewave® Sharp rotors could be used to compensate the turbine weight.
And also this AWES could be used in both static and crosswind versions, by choosing suitable compromises.
A pair of turbines can be enough, the whole remaining more easily handled.
