Offshore Comparison : Makani vs HAWT - Engineering / System Design - AWESystems Forum (in 2019):
This is described in the same terms in the video. @derek (2019) and @derek-rewind (2026) could be the same person?
AWE situation does not seem to have changed much from 2019 to 2026, not to mention the many preceding years.
Thus, standard wind turbines (HAWT) have resolved all the issues mentioned (power to space use ratio, irregular power leading to losses, low elevation angle for tilted devices, reliability, complexity and so on) by using a non-tilted rotor mounted on a tower for maximum efficiency.
It remains to be seen whether and how AWE could overcome its disadvantages, perhaps by harnessing the truly stronger high-altitude wind energy, as originally envisaged?
I see no other possibilities, since at standard altitudes, HAWTs are bound to predominate, as they continue to do unchallenged.
