Drag-mode airborne wind energy vs. wind turbines: An analysis of power production, variability and geography


Looking forward to when this one is openly published.

Lead author, Elena Maltz, began by co-authoring AWE papers since at least 2017, with various other known researchers. Great to see her persistent effort-


Rather than superior consistency, perhaps the top advantage of AWE is opening up superior Upper Wind that conventional WT towers cannot reach. Inconsistency of AWES operations will long be subject to the starting imperfections of AWES design and operations; parameters that will take decades to fully develop to superior levels.

And yes, it seems that AWE will be superior if the costs are signifcantly lower than for Wind turbines. There are also locations which are more / less advantageous for AWE.


Nice thorough study Elena!
Looking forward to the days when there’s enough data for mechanical drag mode to be included in this study.

In the concerned publications AWES are always superior to wind turbines for years.
But these still make 100% of the wind production, I wonder why…

Its the “AWE as newborn baby” dynamic. AWE is reasonably predicted to eventually super-cede conventional wind power, by inherent theoretic advantages, but has not done so yet. A baby needs time to grow, to realize its destiny.

This publication is now available. This paper provides also some useful extrapolated data about Makani wings (see the table 1), such like surface area (respectively 70 m² and 36 m² for the 2 MW and 0.666 MW wings), lift and drag coefficients (2 and 0.06; 2.8 and 0.15), tether diameter…
