My definition of electrical power production is whatever Electrical Engineering accepts as such. Same with KiteSurfing as AWE, as defined by the basic physics.
Popular opinion is a poorer guide to technical usages than citing formal criteria. I therefore count aviation tailwinds as AWE, with proportional fuel savings, and bird soaring, wind-seeds, and even toy kites. These are all formally AWE and worthy of study. Magnus kites too, but its one of the weak AWE ideas.
