The heading AWE Q&A deserves much better.
Q1 is almost always, what happens when the wind dies?
A1.a we take the kites down automatically and can easily service or relaunch.
A1.b we can still keep the kites flying with pumping energy.
A1.c the wind resource at high altitude is incredibly reliable.

Q2...

That's a great picture thanks Pierre.
I coordinated my 6 driver kites, 2 ring kites and 1 lift kite again this week. (at last, after a long break)
But crucially, I didn't realise that my bike battery was below the minimum charge needed for regeneration. Doh.

The body of this tech is to include even the single-wing-element with narrow one-tether (that is a working loop) where the loop drives a groundgen. And such at all workable scales. E.g., sport scale: Have TWTAK where central wing dorsal flywheel is foundation for the long loop; the long loop is both the main load-line tether for the kiting, but is the base tool with its longitudinal rotation for driving the groundgen which could be hand held or not.

Similarly, instead of the above single loop tethering working AWES TWTAK, one may have lateral left and right line sets. Each of the later line sets are working long loops that drive the shaft of a groundgen. One expression could be a sport's handheld control bar complex that has built-in inner generator shaft and generator. The human holding surface tube encasing the generator shaft (except the generator shaft is accessed by the loops at the left and right ends of the control-bar complex.  The generator body is fixed well to the control bar outside tube that is stayed by the human grip; such permits the shaft to be turned while the generator body remains relationally fixed. The TW in excess wind allows mining of some of its energy for turning the loops that turn the generator.   In a sports expression, one may use the electricity to warm one's body, energize LEDs surrounding one's body for night visibility or messaging or for charging electrical batteries or driving other electrical instruments.   

The flygen versions of these matters are already well into the public domain. The groundgen versions expressed are unfolding the topic in this discussion thread.

Any novelty expressed licenses as per first post of this topic thread.      TIA.

Correcting core acronyms in place:

=============================================

This note is to distinguish two topics. The present topic has TWs with axis of rotation traverse to wind.

The separate different topic could be HAWT set aloft I flygen or groundgen schemes.

Off present topic is Pierre's arch of rotor wings where the axis of rotation is not normal to the wind.

See his video here to help distinguish the two topics; we have other topics started for his fine offer:

Of course, a tweak to replace the HAWT with VAWT TWs would bring the changed scheme to this topic, but with the flygen aspect. Flygen VAWT and flygen HAWT have a long patent history; it is encourage to study and discuss those schemes in their own topic threads; yes. TIA.

Rod fairly asked:

"Before I question the energy balance or why heat a sports person... "

Thanks, Rod,

         Sports person is out in the wind and cold. He or she is sporting some AWES experiments that don't quite warm his or her body enough. And clothing was not quite enough to keep warm enough.  So, he or she directs some of the sport-sized AWES energy mined into heating elements set in one's clothing. Presto: sports person is warmed by using immediately-gained kitricity.   I think your formerly posted heating a cup of Jo or something, did you not? 

     Also, a companion might want to sit in the cold and observe things in the AWES experiment field; that person might be warmed by the kitricity.

     Or visitors to an AWES demo; let them feel the heat from using kitricity.  

Etc.

     Warm the air in a shelter?  Cook? Heat plastic to melt for use in field kite craft.  Etc.

Single TWTAK with four TWs and spread anchors. The load line (LL) goes through bearings. Axial sticks are  not needed  (as are needed often in non-spread-anchor systems).   TWs may vary in area, aspect ratio, material choices.

See attached drawing of a 4-TW TWTAK.  The two anchors are not shown. Not shown are the ground-placed generator(s) or other loads to be driven by the loops. Load on loops must not slow the wing below a threshold where the wing lacks lift enough to fly the arch, unless we add a lifter kite system to the shown system or leave some of the TWs unloaded without PTO action.

The drawing does not depict fencing, matrixing, doming, stacks, ladders, or  clusters where TWs are element wings of the complexes.

Abstract

Ground based wind energy systems have reached the peak of their capacity. Wind instability, high cost of installations and small power output of a single unit are some of the the limitations of the current design. In order to become competitive the wind energy industry needs new methods to extract energy from the wind. The Earth’s surface creates a boundary layer effect on the wind that increases its speed with altitude. In fact, with altitude the wind is not only stronger, but steadier. In order to capitalize these strong streams new extraction methods were proposed. One of these solutions is to drive a generator using a tethered kite. This concept allows very large power outputs per unit. The major goal of this work is to study a possible trajectory of the kite in order to maximize the power output using an optimal control software - Imperial College London Optimal Control Software (ICLOCS), model and optimize it.

====================================================

This paper gives me hint of how large the confusion may be on the term "laddermill" among those approaching AWE. The impact of an astronaut over the field!  Wubbo J Ockels continues to have his say!  

Fry and Hise had second anchor as a lifter kite or inflated arch lifter or terrain-held-high cable, or set of towers. PTO : torque to groundgen.  Filed January 1976.  One of the early roots of multi-rotors for torque shafts. I join this patent in this topic for distinguishing PTO scheme and non-terrain second anchor; the catenary arch is still formed with VAWTs on the LL  Such scheme is not the loop or fan-belt.   Fry and Hise did seem to use forms of rotor wings ---even perhaps TW in the LL with LL as axis of rotation.

Thanks for note, Rod.

I will later be copying your skybow notes and my skybow notes into a collection topic dedicated to skybow matters.

Yes, Jim Malbos had noted segmenting skybow to respect wind gradient; but notice that torque from a swiveled upper skybow segment does not translate along to the anchors fully. If PTO by torque from the tumbling skybow is wanted at the anchors, then swiveled segmenting defeats part of such mission.

I am aiming for the present topic to deal with the TWTAK that has nearly no torque occurring on the full LL (load line or arch line to anchors); thus the topic herein this thread would deal with TWs in the arch or complex that were NOT giving significant torque to the LL.   I aim to deal with skybow and Fry and Hise torque shafts/lines/cables/tube complexes that torque in other topics.  

The TWs of this topic thread are self-swiveling with what I call "free bearing" where each wing is fully independent of adjacent wings and have very little friction at bearing on the LL; the LL freely travels through low-friction open-hole bearings; when needed some sheath protection of LL and some low-friction bearings would be matured to allow the TW to autorotate without giving significant friction to the LL; larger systems and for endurance, some lubrication will be needed.

Joachim Nellißen and his rotor array kite system

See his rotor kite. On his page he has several photographs.

The wing arrays in one frame 18 rotors that seem to be barrel rolling rather than Bernoulli-Magnus tumbling, as the bridling seems to provide HAWT approximation rather than traverse-to-wind VAWT dynamics.  

See several photos:

We have notes in forum and associated web about using kite systems in order to mine the temperature gradient from ground level to upper altitudes. Where the gradient is strong, there may be increasing practical benefits. This topic thread invites collecting notes and furthering the tech regarding mining the temperature differences in the atmosphere using kite systems. Some will explore even making electricity using the temperature difference. Other explorations are invited.

Health, medicine, food, recreation, entrainment, manufacturing, water, ice, freezing, cooling, energy ... are teasing concerns.  Details of solutions are invited. Patents? Open source? Installations? Experiments? Challenges?

Notice that one may fly specialty kite systems into fires for various reasons: fire fighting, drawing energy from the heat, manufacturing, art, and more. Explore flying special kite systems into fires, volcano gases, into and then out of hot realms, ...  What else?   How and why?

Why ever have kited wings set on fire?   Setting back fires at spots otherwise not reachable?  What else?

This topic thread will be here for years to come. If you have a note toward the topic: WELCOME.

Appending to the tech of topic under intro-post licensing

is a coordinated system of two PTO means:

The described drop loops damp and may brake to generate ground electricity or serve other loads; such damping may be sized and timed in sinusoidal rhythms to allow a second PTO means in coordination: the LL will rise and fall in tension; that cyclic changing of tension will be mined at the system's main anchor stations to generate electricity or serve other loads.  The two means of PTO coordinate.  Teamwork.

=======================

Notice that the coordinating two PTO means is not an AoA scene, but rather a variation of rotation of TWs bringing on a variation in LL tension. While the loop damping is oscillating, then the LL tension is oscillating. There will be a rising and falling of the arch altitude during the power-generating processes.

A fourth PTO of TWTAK involves aerial complexes of TWTAK acting to hold broad netting that both integrate the several arches and act as fall arrest for upper higher aerotecture where humans operate or live. The power of the TWTAK complex holding up the wide-hole mesh could catch and arrest the falling masses. This scene has a severe challenge: One does not want the human to be slapped by the rotating TWs, or grabbed and thrown through at the TW space; the mitigation here is the having of TW elements be fairly innocent low-chord wings, but have massive amounts of the TWs.
