An article just published in the paper edition and digital edition of Physics World titled A brief history of
kite physics in
the February 2020 on page 20 in FEEDBACK may be studied; authors: Dave
Santos and Joe Faust. In the section also were some suggestions by
Jorge Quintanilla,
University of Kent, UK.
My recent reply to Jorge Quintanilla:
Jorge,
I appreciated your suggestion regarding zero-wind kites. We sometimes call the realm “calm kiting” and “calm kites.”
The upper wind is very rarely really calm.
AWE has step-towing and towing from the ground to address some of the calm challenges.
Also, we have the ground-powered source in a tri-tether system that may keep a wing set aloft during a calm period.
As you indicated also, gliding and soaring in horizontal calms by the use of vertical thermals remains a potential solution.
And the use of changing altitudes away from a calm layer is available.
Also,
FFAWE (free-flight AWE) where there are no tethers to the ground uses
the asset of two strata of winds where the winds at their respective
layers are in different directions or at different speeds in the same
direction.
Feel free to address AWE matters via posts into the open-public forum:

Fun to be in Physics World next to your contribution,
Best to you and yours,
Joe Faust
