Yes if we consider the swept area as for current wind turbines as it is discussed above. Within a given swept area the limit of really drag-based reeling yoyo kite is 4/27 (as mentioned above), while it is 16/27 (Betz limit, as mentioned above) for really lift-based-turbine onboard or some rotary kite systems such like SuperTurbine ™ or Daisy. But Loyd’s formula considers the kite area, not the swept area, finding an equivalent result for drag (in fact lift) and lift (in fact drag) based kites. And as developers consider that a crosswind kite harnesses a tiny part of the swept area, the numbers 4/27 and 16/27 have no practical effect for the time being. The problem is also that for crosswind kites the swept area is not easy to define accurately. Indeed a kite can swept a huge swept area while the real harnessed power is tiny due to its possibly low power harvesting factor. Imho a practical measure would be by using the Power to space use ratio, defining the ratio of the wind power within the frontal airspace / space and land use area.
