If he were the only one to forget this concern… And this is one of the major points making HAWT devices that AWES cannot (or very hardly) compete with in utility-scale, unless they can evolve towards gigantism (well beyond what HAWT could achieve) in order to maximize the power to space use ratio.
Otherwise some niche markets can occur by exploiting their mobility, up to a drone that would search for good locations and deploy automatically to store energy in a battery or even recharge the car battery. Perhaps significant individual uses could then arise.
