Seems redundant to celebrate merely flying a kite in a figure-8 after all these years of AWE attempts. I also note when I checked the website Kitekraft - About the “papers” use the term “drag” to describe a machine that uses lift in many ways. In wind energy, the term “drag” as applied to any device or design (such as a Savonius cup-anemometer-type machine), traditionally refers to working surfaces being “dragged” (or pushed by brute force) to travel downwind, to distinguish from the normal use of “lift” (airfoils) to produce power directly. I do understand how the newbies think “drag” refers to “dragging a propeller upwind through the air” but the term “drag” or “drag device” with regard to wind energy is already long-established. It means working surfaces traveling downwind, NOT upwind. A closer design space to a traditional “drag” machine is kite-reeling, where the lift of airfoils is nonetheless used to create a “drag” type of machine (working surfaces travel downwind). Reminds me of my mom’s attempted explanation of the term “drag-racing” - “because they drag their feet to stop?” Nice try Mom!
