This may be true, but it may not be the reason for the stagnation of AWE.
Have you considered that this could also be because those who know about wind energy show no interest in AWE (with the exception of Dr. Fort Felker)?
Considering these two points of view as true or not true, and being optimistic, we can also think that wind energy by AWE bears little resemblance to conventional wind energy in a technical point of view, even apart from the fact that it is not operational.
As a result, it may not be so important that AWE developers have little knowledge of conventional wind power, knowing that wind developers don’t care about AWE, both confirming the narrowness of the intersection between these two fields.
