A fairly typical AWE patent, in the sense that its not very novel, nor highly developed. The best-practice reaction is polite demurral and best regards to the inventor.

China is like any other country these-days, granting patents to anyone who pays the filing fees. Inventive-leap and prior-art are no longer seriously examined, most patents still do nothing, and a tiny few are dramatically wielded and litigated. In most economic sectors, IP pools long ago resolved patent thickets, and AWE is on the same path.

A ducted-turbine AWES, with all the technical implications long discussed.

We can see China now able to counter any Western AWE patent advantage by similar patents of its own, and no prospect all these cross-patents will be meaningfully reconciled, and maybe even that patents no longer count as much in this brave new world, even as shared art, since so many other channels for inventive knowledge have opened. The world is far more complex, and the rules are shifting under our feet.

Expect any patented AWE to be freely hacked by all who struggle to make it work better, without systematic royalty payments or follow-on patenting. On the other hand, maybe China represents a delayed era of classical patenting focused internally. To compensate for restricted Net access, the PRC may be serving up a patent flood to its mega-populace.

Kytoon lifting a WECS array; a very ordinary concept with a mountain of prior art. Could it be that some Chinese inventors have a linguistic search-disadvantage driving a high proportion of poorly informed filings? How well do they access Western patents? Its not so much that the West was ahead in kites, but that it had a long head-start garnering patent records.

Hand-drawn, as if by a child, this is perhaps the best new Chinese patent of this bunch

A flattened-crosswind-loop-track resolves the common defect of circular VAWT motion, of long upwind/downwind phases. The proposed low-complexity passive-control basis is very similar to KiteLab and kPower ideas, of a gap-tunable double cable-loops, to comprise a single input-channel steering the kites, in this scheme by the tail, which LTA lift would allow (normal tail-catching trips a kite into a dive).

Congratulations to Bing Yang for his potentially scalable and practical AWES vision, with its nice low-complexity open-AWE affinities. Like other AWE architectures, every major concept brings together folks from all over.

Given the flood of new AWE patents, its going to be a challenge especially to weed through the marginal schemes. Perhaps we should batch patents together in messages, and be ready to reconsider whether there is really enough new art to merit comprehensive attention.

This patent is a particular improbability, for reasons often cited (energy density, storm risk).

A professional rope company with a particular polyester-sheathed carbon-fiber kiteline that may well be great, but there are many suppliers of great line, including much simpler products based on pure UHMWPE with various utility coatings. Like many AWE details, the exact choice of line will not matter as much as generic COTS availability. Carbon-fiber based line is rare, is questioned on various grounds, and does not seem to compete in cost-performance with standard fishing and kite lines.

Collect water from the atmosphere aloft; use the mass of the water to drive the system's tether loop to drive an electric ground gen. Keep collecting that water aloft; keep driving the system's cable loop as the water is let down from aloft to the ground. Also, use the cool water on the ground for various purposes. Keep using the aloft station for photography and surveillance and communications relay.  All good works happening simultaneously!  And, also during the collection and letting-down process, let the tether set waft levers at the ground to generate electricity. Or let the system also use the Peter R. Payne and Charles McCutchen means. All the AWE circus in one system!       While at it, sell some advertising space on the lines: line laundry. 

    Two weeks ago my AWES collected so much water aloft that the wing came down on its own being so weighted; had the water been collected aloft and let down using a loop connected to a groundgen, some electricity could have been made from that water-collection and let-down process. The let-down loop could be fully separate from wing-set tether lines.

Hi JoeF,
I like new ideas -- even if they are not yet thought through -- because they
can spark new approaches or inventions.
An idea that came to me after reading your post is to use a tether that
absorbs water easily, as did your kite. Make the tether in the form of a
loop belt. Fly the kite into clouds until the parts of the tether in the
clouds saturate with water. Then start the tether circulating with a small
motor on the ground. Not much powered circulation is needed. As soon as the
downward moving side of the tether becomes heavier than the upward moving
side, the loop belt will begin to circulate on its own.
On the ground, pass the bottom of the loop through two rollers that squeeze
the water out of it. There should be enough power created by the loop belt
itself to provide the energy needed to squeeze the water out of it, and so
sustain its own circulation.
This idea is based on the fact that well-pumps have been constructed using
an absorbent loop of material, with rollers that squeeze out the water at
the top of the well. Such pumps do actually work, but they are not very
efficient because squeezing the water out consumes a significant amount of
energy. (Rope pumps work much better.) But since a kite's loop tether could
provide energy to do its own squeezing, the idea might work. An energy kite
could be added or used instead of the pilot kite to provide additional
energy to squeeze the water out of the loop belt.
The problems are that not a lot of water could be captured by a single loop
belt (small total area of absorption), and the shape of the loop belt's
cross-section might induce flutter and excessive drag.
A solution might be to use multiple loop belts per single pilot kite, and
then find a cross-section configuration of the loop belt that would suppress
flutter.
It would be necessary to maximize the length of loop tether that was inside
of the clouds so as to maximize the working surface area of the loop belt.
If the loop belt produced more energy than would be required to squeeze
itself, then the motor could be used as a generator to produce a small
amount of electricity to charge the battery used by the motor, and maybe an
additional battery to be used for LED lighting, etc.
I'm ignoring the problems of launching and retrieving for now and I'm
assuming that it will be done manually. An automatic mechanism would
probably make the water kite too expensive to use to obtain a small amount
of water. But for poor people living in arid areas, manual launching and
retrieval might be worth their time.
There are other question to consider such as how reasonably low clouds and
winds are correlated. In other words, is there likely to be enough wind to
access the clouds. And in arid areas, how often would accessible clouds be
available, and would that make a water absorbing kite worth its cost?

Subject: Chinese AWE Excitement
Historical transformations in energy took generations. The RAD (rapid AWE dev) doctrine, and public voices like Bill Gates, have proposed an accelerated effort that points to 2030, or thereabouts*, for AWE to develop into an industrial-scale energy source.

One of the factors that promise to keep us on track is an evident surge in Chinese AWE R&D, which could effectively double the global talent pool over Western R&D alone. Chinese AWE patents are surely just the tip of a tech iceberg, and we can expect a flood of Chinese papers, conferences, prototypes, academic teams, and commercial ventures. 

RAD has positioned us with a slight lead in domain expertise. For now, the names and assignees on the Chinese patents represent a trail to follow, and machine-translation is working well enough to move forward. Welcome to our Chinese brothers and sisters in AWE, who are sure to make many essential advances to keep us on the 2030 track.

Noting more key factors in China's favor in AWES R&D; that they have the longest, broadest, and largest ancient kite tradition, and today manufacture almost all power kites at very high quality.

​Mo Zi 墨子, a renowned Chinese philosopher, during the Warring States era in China 春秋末战国 took three years to make a wooden kite. After it was flown for a day, it broke.

His disciples praised him, “It is incredible that you made a wooden kite that can fly!”

 “It took me three years to make that wooden kite.” Mo Zi said. “However, it could only fly for a day before it broke down. How can one be proud of that? Take the cart maker. He used some wood and in a day can make a cart that can carry heavy loads for long distances for long time periods: that is real skill!”

Clip from Shell CTO Yuri Sebregts' remarks:  
"All of us are focused on innovation when it comes to climate change. For example, we are working with a company that is capturing energy with kites. This is very innovative because you do not need these heavy wind turbines anymore. This British startup called Kite Power Systems generates energy with kites connected to a spool and a drum, which moves when the wind sways. The energy is generated based on the movement. Each kite provides a lot of energy and can provide energy to hundreds of homes."

Subject: Giant Chicken Heart AWES Concept
Imagine a vast AWES metamaterial lattice pumping coherently like a giant heart muscle as wind passes thru it. Such bulk contractions could be tapped for plentiful energy. Just how to coordinate such kitematter contractions is an open study; they might be passive bulk motions, like the natural waving of a flag, or directed motions by a "pacemaker" process. A key challenge is variable pumping to match broad loading and wind conditions.

Tapping megascale kitematter lattice-waves is a theoretic AWES concept that closely resembles a modern folkloric horror trope of an unstoppable beating Giant Chicken Heart, hence the whimsical name for a serious idea.

Launching Customer

 
In de afgelopen jaren hebben we veel werk verzet om ons voor te bereiden op de commercialisatie van onze technologie. De gesprekken met onze launching customer lopen al ruim twee jaar waarin intensief  onderzoek  werd uitgevoerd  naar  de technische en commerciële haalbaarheid van verschillende Airborne Wind Energy concepten. Dat onderzoek  heeft onze leidende  positie  in  deze  sector bevestigd. De  samenwerking  met  deze launching customer is een enorm belangrijke mijlpaal voor ons bedrijf.

Nieuwe website
Om diegenen die overwegen te investeren in ons bedrijf zo goed mogelijk te informeren, zijn we onze website aan het updaten. Op de vernieuwde website zal veel informatie te vinden zijn over de technologie en de voortgang die we boeken. Ook zullen we de Ampyx Power story vertellen aan de hand van milestones die we behaalden.
 
 

Market Entry

 
Ampyx Power heeft de wereldwijde windenergiemarkt in kaart gebracht om te bepalen in welke toepassing de   unieke   eigenschappen  van Airborne   Wind   Energy   Systemen (AWES) het grootste concurrentievoordeel opleveren. We  hebben geconcludeerd  dat  onze  systemen  zich  uitstekend lenen  om  conventionele  windturbines  op  zee,  die  aan  het  einde  van  hun levensduur  zijn, te vervangen.  Met gebruikmaking van onze  AWES kan  de  levensduur van de  eerste en tweede generatie offshore windparken op een efficiënte manier verlengd worden, doordat de bestaande civiele en elektrische infrastructuur (funderingen, bekabeling en netaansluiting op land) hergebruikt kan worden. Hergebruik van de bestaande infrastructuur  is  niet  mogelijk  wanneer  de  versleten windmolens door nieuwe conventionele wind turbines worden vervangen. Door diverse experts is de  business  case  van Ampyx Power’s AWES in deze markt bevestigd, en ook Ampyx Power’s launching  customer beschouwt  de  renovatie  van  haar  bestaande  offshore  windparken  als  een aantrekkelijke propositie.

STAK bestuur

 
Informele investeerders van Ampyx Power investeren door certificaten te kopen die worden uitgegeven door de “STAK”, Stichting  Administratiekantoor  Informele  Investeerders  Ampyx Power, geregistreerd  bij  de  KvK  onder  nummer  57776326. De certificaten zijn verbonden met een onderliggend aandeel dat door de STAK wordt gehouden. Alle financiële voordelen van de onderliggende aandelen zijn uiteraard voor de houders van Certificaten, maar het bestuur van de STAK oefent het stemrecht op de onderliggende aandelen uit. Het bestuur van de STAK bestaat uit vijf onbezoldigde leden, waarvan er vier tweejaarlijks worden verkozen door de houders van Certificaten. Het vijfde bestuurslid wordt genomineerd door Ampyx Power. Tot nu toe investeerden zo’n 400 mensen in Ampyx Power waardoor de STAK inmiddels met een belang van ruim 20% een belangrijke positie aan de aandeelhouderstafel heeft.
Momenteel bestaat het STAK bestuur uit:

We hope for your support during the upcoming campaign. Will you be our ambassador?

 
Launching customer
We have made relentless efforts to prepare for the commercialization of our technology over the last few years. The discussions with our launching customer have taken more than two years, during which they thoroughly investigated the technical and commercial feasibility of various Airborne Wind Energy concepts. This investigation confirmed our position as leaders in the Airborne Wind Energy sector. This cooperation with our launching customer is a tremendously important milestone for our company.
 
New website?
We are upgrading our website to keep potential investors as up to date as possible. The new website will have a lot of information about the technology and the progress we are making. We will reveal the full Ampyx Power story and all the milestones we’ve reached so far.
 
 
Market Entry
Ampyx Power mapped the global wind energy market to determine which application of the unique properties of Airborne Wind Energy Systems (AWES) delivers the largest competitive advantage. It was concluded that AWES are ideal to replace conventional offshore wind turbines which are at the end of their service life. Using AWES, the lifetime of the first and second generation offshore wind parks can be efficiently extended because the existing civil and electrical infrastructure (such as foundations, intra-park cabling and connections to the onshore grid) can be re-used. Re-use of existing infrastructure is not, or only partly, possible if the written-off wind turbines are replaced by new conventional wind turbines. Various experts have confirmed the business case of Ampyx Power's AWES in this market, and Ampyx Power's launching customer also regards the renovation of its existing offshore wind parks with AWES as an attractive proposition.
 
 
STAK board
Informal investors in Ampyx Power can buy Depository Receipts through the Stichting Administratiekantoor Informele Investeerders Ampyx Power, in English: Administrative Foundation Informal Investors Ampyx Power, registered at the Chamber of Commerce in The Hague with number 57776326 (“AF”).  A Depository Receipt is comparable to a share in the equity of Ampyx Power, with the difference that Depository Receipts do not give voting rights in the shareholders’ meetings of Ampyx Power. Depository Receipts are issued by the AF, and are linked to an underlying share, which is held by the AF. All financial benefits of the underlying shares will be for the holders of Depository Receipts, while the Board of the AF exercises the voting rights of the underlying shares.
The board of the AF consists of five unsalaried members, of which four are elected by the holders of Depository Receipts and serve two-year terms. The fifth member is nominated by Ampyx Power. The board of the AF currently consists of Berend Jan Kingma (chairman), Job de Visser, Willem van Putten, Richard Kooloos and Bert Dequae.
So far 400 people have invested in Ampyx Power of which the STAK board represents a 20% share.

This is clearly the same concept we have discussed in varied details and cases, from solar-charged e-paramotoring to solar parafoil HALE. While this patent is five years old, it would be easy to dredge up a mountain of prior art to justify an obviousness finding.

Original or not, the low-wing-loading e-flight concept space is rich in opportunity. Basic advantages include low-cost unit-lift at a low sink-rate comparable to high-cost high-performance gliders; and in tethered form, better min-velocity match to most-probable winds.

Subject: Brief History of AWE; and why progress is so rapid
When first kite flew in water or sky, kite energy was born, since kites are inherently energy devices. The kite principle occurs in many biological similarity cases, including microbial cases, with billions of years of prior natural history. The human-made kite is variously regarded as a probable stone age invention as old as 40 thousand years (based on cave pictographs, and given that kite aero-tech is comparable to returning boomerangs uncovered from that era, but kites tended to rot away without a trace.

Over two thousand years ago, historical kites arise in China, in the Warring States period. Even then, manned flight and aerial bombardment is documented. Japan saw kites used to lift construction materials. Polynesians used kites to fish, pull canoes, and even extract water from clouds by flying sponges in them. Every odd use of a kite is AWE art to reapply to core kite capabilities. The Western Enlightenment discovered in the kite a scientific capability, and this was the intellectual context in which Etzler proposed powering civilization by means of kites almost two centuries ago.

Pocock was the first modern kite expert, not just lifting payloads, including his own family, but also pulling boats and carts with steerable kites. This was the Golden Age of Sail, and an associated Golden Age of Kites occurred in tandem, with many modern man-lifting and record-altitude firsts. Most notably, powered aviation emerged from kites of the period.

While there seemed to be a pause in kite progress as powered aviation matured, progress nevertheless proceeded in niches like aerotow soaring, weather kites, and barrage kites. Transport aircraft mastered reducing fuel use by about 5% by playing tail-winds, as a major AWE case. It seemed that the kite itself was being relegated to toy status, but it became a real workhorse instead.

The Aerospace Age created the modern parafoil and NASA Power Wing, that became standard in new kite sports and ship kites emerging in the '90s. Just twenty years later, our time, the AWE field has grown from a handful of serious developers to over a thousand. Relentless increase in kite knowledge, better materials, and fresh talent are driving the rapid progress. General flight automation is also evolving rapidly as a tech driver in AWE.

At the current rate of progress, kites will transform the world within the lifetime of those reading these words. Rapid AWE Progress (RAD) is as much a fact of life as an aspiration. Last but not least, many of the most talented and dedicated AWE developers are driven by a social urgency to develop abundant renewable energy, the RAD ethos.

In just the last ten years, many records and firsts have been documented on the AWES Forum, too many to list here. Ten years is just 1/4000th of the possible existence of human kites. The recent trend for accelerated kite-tech progress seems well-established, and may continue indefinitely, especially as China, India, and other rapidly developing populations enter the quest for AWE. 

What a wonderful era of wind-tech exploration that we are helping make happen a bit faster than it otherwise would, without our efforts.

Group: AirborneWindEnergy Message: 22503 From: Peter A. Sharp Date: 4/8/2017
Subject: Re: AWE FORWARD
Something to consider is that the cost of ground-based wind turbines may
drop significantly by the time that energy kites go into production. For
example, VAWT based wind farms, or combinations of HAWT and VAWT wind farms,
may more than double the energy capture of wind farms, and might achieve a
50% reduction in the cost of energy, or better. If so, then the future of
AWE would be in doubt if energy kites (not including traction kites for
ships, or underwater kites) can achieve only a 50% reduction in the cost of
energy from the wind relative to current HAWT wind farms.

My guess is that one form of energy kite that will become competitive is the
use of Makani-type kites that land on water using pontoons like seaplanes.
So launching will be easy -- by towing the kite rapidly toward its anchor
point (the way some gliders are launched) -- because the floating kite will
easily orient itself downwind to be ready for takeoff. No tower or tricky
landings on a tower would be required. And in cyclones, the kite will
continue to fly while just facing into the wind because the wind speeds will
still be within the normal flight speed of the kite. The anchor point might
be, in some cases, a Turboship that would fly multiple energy kites, and
follow seasonal winds so as to produce hydrogen that could be shipped to
port cities. The first customers would be islands, like Hawaii, where fuel
costs are especially high.

In other words, energy kites may have a role to play, but not as broadly as
is currently hoped. My guess is that successful energy kites will be those
that focus on narrow, specific markets. From that beginning, their use may
gradually expand to other markets.

HAWTs themselves could be relegated to marginal use by the success of a new energy like, say, fusion. AWE could be the bridge to fusion. Cheaper wind towers are an unlikely fundamental solution.

Its a bit of stretch to claim either wind towers or AWE are soon kill the other off. After all, the world's geographic and economic conditions vary greatly, where each wind method has its favored sites, and they can even co-exist, since they operate in distinct regions of the sky.

The AWE community is the place to bet against wind towers being the only wind solution on Earth. A wind tower forum or career would be ways to bet against AWE dominating wind harvesting. The hope that upper-wind is a key solution remains bright within the AWE expert community,

Something to consider is that the cost of ground-based wind turbines may
drop significantly by the time that energy kites go into production. For
example, VAWT based wind farms, or combinations of HAWT and VAWT wind farms,
may more than double the energy capture of wind farms, and might achieve a
50% reduction in the cost of energy, or better. If so, then the future of
AWE would be in doubt if energy kites (not including traction kites for
ships, or underwater kites) can achieve only a 50% reduction in the cost of
energy from the wind relative to current HAWT wind farms.

My guess is that one form of energy kite that will become competitive is the
use of Makani-type kites that land on water using pontoons like seaplanes.
So launching will be easy -- by towing the kite rapidly toward its anchor
point (the way some gliders are launched) -- because the floating kite will
easily orient itself downwind to be ready for takeoff. No tower or tricky
landings on a tower would be required. And in cyclones, the kite will
continue to fly while just facing into the wind because the wind speeds will
still be within the normal flight speed of the kite. The anchor point might
be, in some cases, a Turboship that would fly multiple energy kites, and
follow seasonal winds so as to produce hydrogen that could be shipped to
port cities. The first customers would be islands, like Hawaii, where fuel
costs are especially high.

In other words, energy kites may have a role to play, but not as broadly as
is currently hoped. My guess is that successful energy kites will be those
that focus on narrow, specific markets. From that beginning, their use may
gradually expand to other markets.

To summarize past analysis of kite water harvesting for context, the theoretic ideal is to be able to hunt out clouds in the sky for harvesting, rather than fly-in-place for random luck encountering dew-point maxima. Just being able to vary elevation as needed would greatly enhance capacity.

Mist-nets seem like the best harvest-to-weight/drag medium. Hoses allow precise lateral water placement at the surface, essential for many apps, like fire-fighting. Some concepts involve two-way water mass transport, as a ballast energy-storage medium. Cooling and ice-making are options. A related concept-space is elevating water en-masse, to seed and feed clouds to break droughts, or reflect excess sunlight to space for global cooling. 

The working idea is that daytime clouds cool by solar reflectance, but nighttime clouds blanket heat in. To go a bit farther, imagine making clouds in the morning, harvesting them in the afternoon, for clear cool nights. This is in fact the tropical pattern in many places, and perhaps we need to extend it.

Thanks Peters!   Your AWE ideas at any point of development are welcome!  
==========================================================
Another Flash Sharing of a moment ago: 
Have a groundgen in Los Angeles at the shore region; have a groundgen at the big island in Hawaii; run a loop line between the two groundgens.  Saddle the lines with goods going to Hawaii and good going to Los Angeles, California.   Now that loop line saddled with goods get driven by wind on tethered wings attached to the part of the loop going to Hawaii.   Return the wings as part of the saddled goods going to Los Angeles. Off goods during the operation. Have electricity being made at both Los Angeles and Hawaii.  And get the benefit of the transfer of goods.   If the speed satisfies the nature of the goods ... great.   If humans want transportation at the resulting rate, then they may attached to the driven loop going the direction they wish.

Hi Pierre,
I agree that VAWT might lead to a large cost reduction in the cost of
ground-based or sea-surface-based wind energy. The Sharp Cycloturbine and
the Bird Windmill have that potential. For example, I have shown how to
stack Sharp Cycloturbines to create an integrated, floating, framed unit
with a rating of 100 MW. It is primarily their exceptionally broad power
curve that enables Sharp Cycloturbines to be stacked so as to not be
handicapped by the wind gradient. This type of array can achieve large cost
savings because each stack within the frame of the array spins much faster
than a HAWT with the same total swept area (similar in principle to Selsam
multi-rotors, which I greatly admire), and the amount of material is greatly
reduced because the array is essentially a 2D structure that benefits from
the square-cube law of scaling. Maintenance is simplified by tipping the
array to horizontal just above the sea surface where all of the parts can be
easily accessed by boats and relatively short cranes. For overspeed control,
the entire array merely leans away from the wind by using retractable
weights that function like a keel.
At present, I'm communicating with 4 different engineers (around the world)
about those two wind turbines, so we'll see....

What PeterS oddly proposes is that AWE and conventional wind, both, may not be able to compete with his Sharp Cycloturbine. His logical case for the Cycloturbine as a substitute for the AWE R&D world seems missing. Is there any working Cycloturbine prototype or expert third-party supportive of PeterS' extremely favorable view of his own idea?

Let the Cycloturbine show up ready to test against all comers in AWE, if its even marginally competitive, and not blame skeptics for the lack of compelling evidence in its favor. Some fair blame is due to inherent design defects, like a bluff center axis, upwind-downwind parasitic cycle phases, square-cube scaling law, and so on, defects which are not seen as sufficiently offset by any advantages, except in the mind of its inventor, and claimed unnamed academic supporters.

Its also puzzling why PeterS took a private AWE thread public, while seemingly wanting to make it a non-AWE or anti-AWE topic.

Subject: Re: Daidalos Capital articles
Congratulations to Udo on wildly successful early rounds of AWE investment. WOW may have been the first AWE venture fund, almost accidentally exiting KiteGen with a small profit, the first such ever in AWE; but Daidalos did AWE venture funding consistently better, and made a tidy 1000% windfall-profit. Its not yet historically decided if Daidalos picked any ultimate AWE winner (unlikely) or just skillfully flipped overvalued assets that follow-on investors are stuck with (more likely), but now Daidalos faces a fresh round of investment choice under the looming prospect of BEV midcap funding.  WOW is apparently sitting on dwindling capital, unable to pick and promote any venture after its KiteGen experience. 

Besides the ongoing possibility to pick top AWE winners, there is now a strong case for larger well-capitalized investors to diversify across the expanded venture pool. Background messaging between WOW, Daidalos, and kPower proposes a mobilization of the greater AWE community to address BEV needs. Daidalos and/or WOW would underwrite a collective R&D plan for BEV, possibly as kPower debt-equity repayable at Daidalos' 10x ROI. The AWE venture funds could themselves transition to BEV agents, for ongoing M&A in AWE, in accordance to the early value they bring. Failure to respond agilely to the new BEV landscape could spell doom to small AWE ventures and investment funds.

It would help if more was known about all other AWE players positioning for BEV, to possibly harmonize the best efforts, rather than present a piecemeal offering of "confidential" proposals that do not as a whole map out an R&D path to AWE.

Subject: Energy modes of a common kite
The kite as a macroscopic quasi-particle has evident but complex energy modes that we have begun to tease apart in recent years. Here is an updated expanded view of kite energy modes:

A kite at rest on the ground can be said to be in its Ground State*; the particle physics term rather uniquely apt. A kite in barely sustained light air flight is at the effective Zero-Point Energy mode. A bit more wind, and the kite acts "pasted to the sky", apparently motionless, but dancing in 6 DOF on a near-microscopic observation scale**. There must be added wind velocity to create net harvestable energy, which in its most common form would be tapped at the ground as a pumping on the line of a fundamental kite harmonic mode.

The ordinary wagging kite-dance is the First Harmonic mode. Its not very stable, and the kite can fall to the side, as its pendulum mass is dominated by centrifugal pseudo-force. If there is more energy, the kite will begin to loop in one direction or the other. This is spin symmetry-breaking in the Second Mode. The Third bulk Mode is for the kite to flat-spin while looping, and once again, the new spin mode breaks symmetry.

 As more energy is added, the kite and tether will increasingly vibrate in discrete interacting internal Chladni modes. These are accounted as higher sub-modes, but some kites, like bird-kites designed to wing-flap, one could rank the flapping motion as a fundamental mode. Many higher mode motions in higher wind happen to fast to observe clearly, so slow motion video is needed. Very complex energy modes emerge by the interactions of wind, kite, and tether, modes that have hardly even been noticed in the general chaos of kite flight, much less classified formally.

Much the same sort of energy modes apply to kite hummers, which are standard on many traditional kites. Cambodian kites are particularly noted for complex multiple musical voices, which we can confidently predict are coupled interactively to the general dance of kite and wind. Our growing understanding of ever-deeper kite physics is driven by the general advance of physics in our time, with the kite exposed as a far deeper scientific object than anyone supposed. 

Not too long ago we could only stare at the dancing kite in uncomprehending admiration, but persistent study and observation are revealing its secrets like some exotic Dance of Seven Veils.

------
* a kite in a bag is another common ground state.

** All modes can be conjectured to sometimes manifest in a weakly excited kite, much as "vacuum fluctuations", and these modes expand into resonant harmonic orders, in steps, as the energy increases.

How would the following be described within that energy-mode system? 
The red dot is the groundgen. The apparent tower could be an aerial cable, a tower, an aircraft, a satellite, a rock bridge, a artificial bridge, a post, a tree, another kite system.  The thickened item coming out of the generator is a stiff lever connected to the tether set that tethers the generic star fluid-reacting wing. Inversion could be in water with the wing in float mode and the apparent tower could then be seabed.  The first view of the drawing would be the using of gravity while wing set and tether are hanging; when no wind, the hanging does not see the wing or tether or lever disturbed; but at the slightest gust the wing is disturbed and deflected; then the tether gets disturbed and the lever gets disturbed; then the lever drives the electric generator. The first dynamics just byond the quiet state could begin to generate electricity even while the wing has not yet reacted enough to move very far vertically.

Subject: Re: Energy modes of a common kite
As drawn, JoeF's kite has an arch topology, with two anchors; so the harmonics are not simply a "common kite", but a sort of inverted catenary with a sensor-like power pick-up. I'll cover simple elaborations in a separate topic on multi-tether and multi-kite lattices. The WECS of this AWES is like a sensitive seismograph, so it would start to make some power with slight motions near the zero-point, but this would be very weak output in proportion to the weak motion. 

All in all, there are infinite uncommon variations of kite elements, and harmonic energy modes may be tricky to characterize at this early stage of our new understanding, which best applies to simple crystal order, but not so much to ad hoc structures.

Subject: Energy modes of kite lattices
The energy modes of a single common kite were summarized in a previous post. When multiple kites are cross-connected in crystal-order, they develop collective energy modes, which may be the most megascalable form of kite energy of all. In traditional recreational kites, these powerful unwanted motions were typically suppressed by feathering and stabilizer features, For AWE, we want to amplify and control these motions to do useful work. An important concept is that multi-kite formations tend to act as one meta-kite, with bulk harmonics similar to a single kite of similar overall form.

In some ways, networked kites with high crystal order are a simpler harmonic problem than a single kite, with its specific self-flying cybernetic features, and complicated tether interactions. An arch-kite made of many kite-units has good overall inherent roll and yaw stability, by being "staked-out", without needing added common kite features (keel, dihedral, and/or Y-bridling). Similarly, kite stack kite-units have extra stability by being constrained within the stack. Kite trains, with longer distances between units, are less fundamentally harmonic overall, with the units less able to share resonance. All this is easily seen at kite festivals with common multi-kite configurations supporting coherent or not so coherent motions.

As we consider theoretic mesh, dome, and 3D kite lattices with high crystal order, harmonics tend to be standard lattice-wave dynamics, with less complications from long-tether interactions, since the lattice can use many identical short tether-units that couple closely to the kite-units. Let it suffice for now to predict that kite lattices will display many distinct energy modes after the manner of he common kite, but also well known in lattice-wave mechanics of crystals and metamaterials. So while there is not much direct kite lattice analysis, there is a wealth of science regarding similarity cases. The biggest engineering challenge is make kite lattice harmonics tunable across a wide range of wind and load conditions, which might create quite a spectacle in the sky, as the pulsing patterns change in realtime.

As we here explore kite lattices theoretically for AWES use, the emerging art is assigned to the Open-AWE_IP-Cloud

Subject: Daidalos: "Don't Build Lever Arms"
In the context of comparing wind towers with AWES, Daidalos makes a general point about how cantilever structure is poorly scalable, so HAWTs are already close to maximum practical economic scale, while energy kites on a tether can reach far higher. An unmentioned aspect is that cantilever wings are scale-limited by the same scaling law, so any AWES architecture based on them, like the lever-arm wings of Daidalos's early investment picks, Ampyx, and Enerkite, face the same grim problem of excess-mass in scaling beyond around 50kW. However, Daidalos seems to have mostly cashed-out from cantilever wing AWE ventures, and could next fund span-loaded soft-wing AWES R&D that is not based on rigid lever-arm wings.

Daidalos:

Just Don’t Build Lever Arms

So how can a wind drone save half the costs of a wind turbine? It’s physics. A basic construction principle for every engineer is to avoid a 90° force on an unsupported lever arm wherever possible. Large bridges are therefore supported by arches, columns, or suspension tethers. If parts cannot be supported they have to be made as short as possible.
Wind turbine engineers have done the opposite. Rightfully wanting to build ever larger and more efficient wind turbines they worked to increase the height of the towers and the length of the blades. Both are lever arms in a 90° angle to the wind force and they are not supported. Wind engineers would love to tether the tower and the blades. But it is not possible. The wind can blow from all directions, so the rotor has to be able to rotate around the tower and the blades have to spin freely. Wind engineers have nonetheless been so successful in building ever larger wind turbines that they now easily hold the world record for building the longest lever arms in all of engineering. But this didn’t help in saving material. The tether of a drone can be 1000 times lighter than the tower of a turbine simply because it avoids lever arms.

Subject: 2017 Texas AWE Encampment- Mustang Island Excursion
The annual kPower Texas AWE Encampment season has begun in Austin, and experiments are now ranging to the Gulf Coast, for beach-work, where the sand provides an ideally flexible anchor-field medium. The current 132m2 Aerotecture Arch will be further developed with a set of payload lines, with some cautious human-lifting possible, and misc smaller AWES experiments will be done, to be detailed in future posts.

The local Port Aransas kite-hobby and kite-sport community has become a regular participant in these coastal visits, and each year a few more show up, and greatly help with the hard and sometimes dangerous work of large kite handling. Strong winds are forecast around scattered storm cells, so it might get exciting.

This report from last year's coastal trip may not have been posted (I only see it in Draft form), so its (re)posted here (if there was a gap to fill) to paint a picture of what these excursions are like.

-----------------------------
Return to Mustang Island

The 2016 Texas AWE Encampment is almost over. Its been very hot, and most of the work has been in the shop, preparing for upcoming major experiments in the US NW. Wind has been pretty good on the tail-end of the El Nino pattern. Recent milestones in Austin include Joe Faust's TumbleWing concept finally caught on video pumping strongly, which Ed linked on his someAWE blog. It was also shown, as expected, that a power-kite (Pansh valved parafoil) directly anchored by its bridle-points as a kite arch, with no tethers, flies stably, as a model for inherently stable megascale aerotecture structure.

The Encampment climax was a return to Mustang Island on the Texas Coast. The steady seabreeze is quite different from the blustery winds inland, and sandy beach provides a convenient anchoring medium to explore anchor-field variations. Participants were mainly new folks from Austin and the local kitesurfers, who were quite excited about AWE. This area is a designated FAA sUAS test zone under UTexasA&M hosting. The local Port Aransas kite shop (Fly it! Port A), owned and operated by lifetime classic kite experts, was brought into the growing coastal AWE R&D network. 

Adam "A-Bomb", our local coastal kite pro last year, was in Florida, and tried too late to use social media to drum up Encampment participation online. Instead, a 22m2 Peter Lynn pilot-lifter attracted local kitesurfers from miles around to join camps, so the kite itself acted as the viral social-media tech, like smoke-signals once served. The primary kitesurfer circle present was Chris, Steve, Brian, and "Cowboy". Steve and his wife operate a medical wellness-center, and are excited to pioneer kite therapy based on World Kite Museum pioneering work and established dolphin and equine therapy models, for both cognitive (PTSD, autism, etc) and physical therapy.

Most of the coastal activity was introductory AWE. New folks got to practice power kiting by day, and KiteSat created a persistent beacon in the night sky, next to the full-moon. The Springer AWE textbook was passed around, and many other misc technical sharings occurred. The 22m2 PLPL actually worked well as a sunshade in the steady breeze, but it would greatly extend utility to rig an x-y line adjustment to keep the shadow in one place during the hot hours. A photo of my my camp-site in deep airborne shade will be posted. This is another kite app JoeF first championed that kPower has validated as workable.
