Pierre,

The Makani realization is not "brilliant" by the highest standard, which is to change the world. All I see in the M600 is a pastiche mediocre of ad hoc and imitative detail. The engineers are "bright" enough to seem brilliant to the wider world, given the public hype.

If Makani's work was truly brilliant compared to aviation's greatest achievements, we should be able to identify the genius(es) responsible. As it is, we can only identify those who steered Makani into a dangerous expensive unreliable AE dead-end; if it is most urgent to replace fossil fuels with kites.

At least you are not paid to praise Makani as an AWE "leader", or "brilliant", rather than downgrade them based on critical errors,

Subject: Re: Two rings stacked

I wish I could accurately obsere the conditions... But unfortunately I'm on a miniscule budget.

Where you observed... "
These two rings are rigged rather close, so more shadowing and wake interference is presemt; but wider spacing will reduce those losses.
"
There will be another point to observe a relational payoff. More tether drag with more spacing or more shadowing with less spacing , which is better... Is wake always bad? You can surf wake. Is shadowing obvious? There's no crease, ripple or flap on the higher and slightly more forward rotated drive kites.

Not sure if the top kite ring did contribute much however as it runs a bit slower than the bottom ring....  It may even have been a hindrance.

ICT in AWE

Information and Communications Technology

History of ICT in kite systems? Intended objectives in AWE for ICT? 

Thresholds of information and communications in kiting operations that receive pointed attention?

Instruments historically used to give information? Contemporary advances? Future? NextGen?

Kinds of information? Means and purposes of communicating? Sensors? Actuators? Smarts? Logging? Learning? Flying controls? Measuring? Comparisons with models. Model tweaking? Ancient kiting ICT? Novelty? Effectiveness of a chosen ICT integration in an AWES? Software?  Hardware? Alternatives?  Raw ICT before it was called ICT? 


What information is received by a smart experienced human's hand and eye and skin, etc. when a human is an active anchor-controller of a working kite system? How might that person use the information? How might the person so involved communicate responses to the received information? How is the system's tether a conduit of information? What does the wing set's motions visually received by the human potentially tell the smart anchor? How might the human respond to fulfill practical tasks with the kite system by effectively processing information and using corporeal sensors and reactors and body muscles? How smart might a kite pilot become? How does learning occur? How is the pilot's brain soft tissue altered by experiences?  Etc.  Explore master deaf pilot Ray Bethell: Amazing KITE Flying!   and  interview.

Subject: 12m2 Looping-Foil Trials in US Pacific NW
The 2015 Texas AWE Encampment recently ended at the UTexas Research Campus as kPower's 12m2 Looping-Foil snapped its lines after just one loop. Testing has now shifted to the NW (Ilwaco). I modified the kite by removing all the brake lines, which really cleaned up the wing. There is now only one front line left, of Purple Plasma UHMWPE (the other front bridle secures to the main line to the pilot-kite. 

Yesterday, RickA and I flew the AWES again, and got about a dozen powerful loops before a new failure mode emerged. The tail-kill line to the pilot-kite was rigged too short, and the looping-foil swept down and caught it, twisting it around and around. I released the main-line, but not quick enough; the pilot-kite did not kill, since twists in the lines locked the kill-line. The entire rig now looped on just its thin kill-line and seemed ready to runaway as a tethered pair in self-sustained flight. Fortunately the wind was moderate and we were just able to wrestle our way up the rig to kill it. I managed to kill the looper along the way by its shackle release on the bar.

It was a very educational session. The looping foil AWES architecture is elegantly powerful, but requires considerable skills to master. The tail-kill method demands a large separation between looper and tail-kill line. Accidental twisting of the looping rig with its tail-kill line is best responded by killing instantly, before lock-up twist can occur.

This topic bears on our growing awareness of the kite as a fundamental revolutionary technological building-block comparable to semiconductors, but at far larger unit scale. Both are suited for either information or power processing, bidirectionally, under the same thermodynamic information theory.

In fact, the semiconductor analogy has driven new kite-lattice ICT and power-app thinking, and novel kite prototypes are being built and tested that otherwise would not exist (kPower).

Subject: Kite Ferry Operation Options

Start:


Kite Ferry GoPro

 

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

Transport people or goods or things up or down kite system lines .. 

And not to forget linear or rotary electric generators in the mix, even combined ... And coupling an up ferry with a down-going ferry on two different lines of a kite system.


Kite ferries may be scaled and configured to fit intended tasks.


Comprehensive description of practical uses of ferrying will unfold in time way past what has been done for centuries. When something in the ferry line of uses comes to mind, consider posting to this topic thread. If the operation or service involves kite ferries, then drop a note here. 


If you would play the game, name each work in sequential order, which see:


KFop#00001  Ferry up a paper message to be dropped to the winds.

KFop#00002  Ferry up an AWES repair technician.

KFop#00003  Ferry up a camera for photographing the wings of the system.

KFop#00004  Ferry up a skydiver for timely release.

KFop#00005  Ferry up an electrical storage battery to be charged aloft by a working flygen AWES.

KFop#00006  Ferry up parts to construct a hang glider launch incline aloft.

KFop#00007  Ferry up food and water for ingestion by the aloft AWES technician.

KFop#00008  Ferry up a set of parachutes for later emergency use by aloft sky-kite-system picnic visitors.

KFop#00009  Ferry up water for use in misting the wind that wafts over plants or people.

KFop#00010  Ferry up gifts to be dropped at meetings of people of any age.

KFop#00011  Ferry up inhabited gliders for release to free-flight.

KFop#00012  Ferry up powered aircraft for release at altitude.

KFop#00013  Ferry up packs of seeds for release to the environment upon approval of authorities.

KFop#00014  Ferry up rehabilitated birds that are ready to be released to their environment.

KFop#00015  Ferry up uninhabited model gliders that are being tested. 

KFop#00016  Ferry down charged batteries from a flygen AWES. Consider a linear generator for return trip.

KFop#00017  Ferry down the aloft worker who wants to go home after a day's work aloft. Consider a linear generator operating during the return trip.


The scheme has room to briefly describe 99999 ferry operation options.  Each option might become part of a service industry.  Using the sequential format, one's posted idea will become part of the historic record here.  Have fun giving light to the future.  Any niche option might spawn a focused topic thread in the AWE world.

The transmission and reception directional sensitivity of a cell phone varies greatly with orientation and complex radio field discontinuities. Below is an idealized transmission pattern; note how polarized the field is. Keeping the phone upright looks generally best, otherwise the deep gaps in the antenna field may prevent transmission. Cell phone networks with many local towers can compensate by real-time switching, so it may be hard to detect the nulls in normal use-

Joe,

We are confirmed in ongoing communication with Makani/GoogleX, via Damon, Fort, and several others, but the problem is the flawed GoogleX NDA culture makes our messages a one-way channel*. These folks are signed to secrecy, and obviously intimidated (and paid-off) from serious public discussion. Even Damon's AWEC2015 talk is being blocked from public view, with no principled explanation.

The best we can do is to continue to hold out publicly for GoogleX AWE reform as it becomes publicly clear that the M600 cannot solve the clean energy crisis by its unsound economics (high-capital cost, poor scalability) and inadequate reliability (not even flown once, much less survived five years to pay-back).

GoogleX AWE reform would ideally take the form of returning to basic kite energy research due diligence, with open sharing of knowledge and resources between all serious players. Instead, GoogleX seems on track to fail utterly in AWE, by having exclusively embraced a marginal architectural down-select. Open-AWE, on the other hand, is a rich garden of more promising ideas,

daveS

* Mostly based on informal face-to-face exchanges with Makani actors over several years, but also evidenced by Corwin and Damon popping up on the AWES Forum to apologize to DaveL, for excessive public hype (which only got worse).

Subject: kPower Ilwaco KiteSat7 Testing
Final KiteSat7 production prototypes are being perfected for New Tech Kites in Austin. Meanwhile, here in Ilwaco, KiteSat7 is being flight tested. Various minor failure modes encountered in searching for optimal design have been cured. Yesterday the NW testing prototype flew flawlessly for an hour. The type now has three hours logged, and its predecessors flew tens-of-hours without a critical failure or mishap. What a fine job to just watch the new machine do its thing.

The previous test had revealed a torsional weakness in the "T-bone"; the single spar with a small T junction section at the kiteline. The T resists yaw forces by kiteline tension, keeping the turbine aligned to the wind, and only needed to be beefed-up to not break in rough usage. This is the actual tech note to Austin, to make the design change Open-AWE-syle. The T-bone solution for a minimal KiteSat spar structure is Open-AWE_IP-Pool.

An AWE example of how Squid Labs founders figured out how to get rich by getting others to simply donate their commercial content rights, under the guise of enlightened social-media dynamics, and then sold the Instructables site for many millions, as a hip advertising platform. Compare with the scope and depth of Open-AWE content.

Not that Yahoo Groups is pure either; this content has a creeping trend toward increased third-party advertising as well. It would be nice if Open-AWE could escape this sort of exploitation, succeeding on its own terms.

Not too funny; after-all, the Squid Labs founders are ruthless capitalists, not humorists. So they created and hyped Instructables, for nice folks like Rod to create the free value for them (Daisy AWES), and they also created and hyped Makani, especially for the Google Founders to buy.

Subject: Rethinking a conventional AWE paradigm (Blade-tip v. Energy Kite)
The long-familiar analogy is misleading; that AWE tech is about duplicating the tip of a HAWT blade. True, crosswind wing motion is the superior operational mode, but sailing and kiting also exploit crosswind wing motion. The analogy badly fails in that HAWTs are fixed ground structures, but AWES are not so spatially fixed, but fundamentally vehicular. In fact, AWES are properly aircraft, subject to the complex flight dynamics, field operations, and airspace regulations of professional aviation, and they operate in a very different upper wind resource. In particular, most of our AWES are kite-based (tethered wings). 

This has always been the prevailing view on the AWES Forum, but there is a gradual evolution in usage and understanding by players like Makani, who began in 2006 by specifically avoiding the "k-word", but lately embrace "energy kite"* (alongside the tired blade-tip analogy). "Energy kite" is a properly descriptive and accurate term for the basic tethered AWES paradigm, and should become more widely used, as kite understanding continues to advance.

--------------------
* "Energy kite" was in occasional public usage long before Makani especially adopted it. Makani's original coinage was "AWT" (Airborne Wind Turbine), but this usage dropped. "Wind Drones" is a new contender in the AWES naming game, but as an investment marketing ploy; not as an engineering term (Daidalos Capital, AWEC2015).

Subject: Cellular Kite Progress
The World Kite Museum (WKM) has tapped me to help curate new exhibits about Cellular Kites. The first exhibit premiering next month for WSIKF2015 will cover rigid sparred types; to be followed in due time by an exhibit of more modern by soft sparless types. Ohashi himself planted the cellular idea at the early WKM, in the '80s. The following summary spans the Cellular Kite timeline, and highlights the major branches of Cellular Kites-

The modern concept of Cellular Kites traces back to Hargrave, and the proliferation of derivative designs, during the "Golden Age of Kites". Bell took the idea to an extreme, encountering scaling limits to rigid spar dependence. Jalbert's parafoil overcame rigid spar scaling limits by pure soft kite structure and he naturally called the ram-air chambers "cells". The Soft Cellular Kite design space was born.

Cellular Kite thinking dates back centuries, in the form of trains like the Chinese Centipede or the cell-grid structure of the Japanese Edo. The word "cell" relates to an enclosure unit in a regular array, and is closely related to the word "web", as a woven fabric. The interdependent ideas reference a periodic arrangement of cells in a web, which allows us define new kite types as Cellular Kites to the degree they match the cell-web configuration.

The latest historical phase of cellular kite thinking begins with Ohashi, who refined and popularized trains, and arches, and even envisioned spider-like Kite Domes. The cells in these concepts are many tiny sparred kites, and scaling is possible by multiplied units, as long as the spars are small. The iconic stacks of Flexifoils that speed-sailing pioneers like Dave Culp used, and kPower's Mothra represent hybrid cases. All this preamble set the stage for the next revolution in kite thinking, in the quest for GW-scale AWES concepts.

What we have been variously calling kite "lattices", "meshes", "domes", etc., are megascalable Soft-Cellular Kite concepts. Their characteristic features are large-scale periodic arrays of interconnected Soft Kite elements rigged more sparsely than the fused cells of a "monolithic" parafoil. There is almost unlimited potential for Soft-Cellular Kite design, as the most promising concept space for large-scale AWE, until perhaps IFO Swarms emerge.

Echoes the earlier post, but as a crossover posting from engineering to finance news. AWE is officially hot-hot-hot.

One reason it seems there are many more EU AWE teams is US players nicely hidden in the extreme glare of GoogleX "moonshot" publicity. The ironic unintended aspect is how stealthy US Open-AWE is. We dance our kites, but nobody can see us :)

Subject: Re: Avoiding breakaways
Breakaways are very rare in modern technical kiting; tending to reflect basic errors in design or pilot judgement, since modern materials, weather forecasting, and engineering best-practices are very robust. Breakaway causes are mostly single-point failure-modes, rigging and operational errors, and freakish surge loadings. The cures are a TQC learning culture, redundant low-consequence fail-soft engineering with high safety margins (multilines, kitekillers), diligent lifecycle maintenance, rigorous ongoing crew training and proficiency practice. Provision should exist for instant warnings to airspace and populations, and a rapid chase and recovery team.

What early this power kite that zipped together in modular sections? A Quadrafoil maybe? The MegaFly also comes in enormous sections for handling-ease more than for operational flexibility. Often early technical evolutions pick up an idea, then it drops, and has to be rediscovered. A quiver seems better for the kite explorer, given the different optimal construction weight between low- and high-wind kites, but modular kites will rule megascale.

Further evidence that most if not all AWES ideas have numerous antecedents in prior art going back generations, if not millenia.

The rotor-train kite idea is potent, but what's lacking under the Open-AWE DIY KIS standard is a simple obvious way for it to pump without needing active controls.

It looks like a repeat post, since the format resembles so much Bell coverage of the period, but I don't recall such penetrating analysis of Bell's cellular ideas (if a bit hyperbolic), with many rare facts and photos. 

Its clear that the sparred-kite scaling-barrier was known over a century ago, even though many AWES developers today still seem unaware of the problem. The great news is a soft-kite revolution expanded the scaling limits by orders-of-magnitude. We are even riding along a sort of Moore's Law curve for growing soft-kite scale, with the recent progress based on many-unit multi-line multi-anchor arrays (kixels along rope loadpaths).

A related conceptual advance is that classic cell-kites can be tensioned by kite arch forces, eliminating dependence on rigid spars. This was the overlooked solution to scaling up Saraceno's Solar Bell kite concept to carry the public up. I plan to take an NTK snowflake cell-kite and replace its hoop spar with a C-kite parafoil and cathedral bridling, for a fully soft variant. (Open-AWE_IP Pool).

Subject: Machine Learning layered on WECS Dynamic Stablity (Siemens' Case)
The "old" automation paradigm in AWE is that complex flight automation is essential, with passive-stabilities and high-level operational logic neglected. Years of Low-Complexity AWE experiments validated the practicality of passive flight dynamic stability (aka "inherent stability") of AWES (KiteLab, etc.), but essential operational logic still requires a pilot or hypothetical smart-system. Thus its an open role for advanced AI methods in AWE, from GA connectionism to domain-expert semantic-logic, to enhance performance and safety. If high-level human-piloting or AI-based flight control falters, its ideal if the AWES defaults to its inherent passive stabilities. This is a better automation paradigm (along with aggregated control at the kitefarm unit-scale).

Here is Siemens wind energy research case of adding a neural-net control layer upon (partial) HAWT dynamic stability-

Subject: Re: Avoiding breakaways

Dave S. mentions "basic errors" as a source of some breakaway kite systems. When anyone cares to describe some basic errors that could lead to breakaways, please do so.


Some line errors

1. Operator fails to know the actual mechanical status of the full line used in the operation following any and all modifications done to the line (knots, connections, splices, age, storage environment, ... ).  A line will be only as good as its weakest link. A weak place in a line may occur at any station of the line.


2. Safety factor was not present at all stations of a line. Quality control and inspection was inadequate. Calculation of operating loads may be short.  


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

Some wish list items:

a. Wings may be told to release lines.

b. Tethers may signal their locations. Have receivers that may locate the tethers.

c. Wings may signal their locations.  Have receivers that locate wings.

d. Have wings that upon release of their lines may glide to home.

e. Quality controls that prevent breakaways.

f. Secondary wing-kill system.

Subject: Re: Avoiding breakaways
A major breakaway error is to be caught by rising wind (breakaways hardly happen in low wind). The Pilot should know the latest forecast and reduce sail ahead of time. An auto-kill system that can parse local METAR data for warnings would be a nice precaution against pilot negligence.

Another basic error promoting breakaways is to fail to closely monitor the state of the kite rig(s) for crossed lines, which can promptly cut each other.

The question is where best to attach the snowflake cells to the arched C-kite. The normal cathedral-bridle line is sure to work, as a default, with a second cathedral line below the snowflake, to tension it out, but its not yet a pure soft kite, since the snowflake needs at least one short axial chord spar. How an optimal fully-soft snowflake would be is an open question, maybe with a ram-air tube center.

Taut line moving against another taut line might become a foundation for a tiny pump that would positively pump air into a ram-air-valved air beam "spar" for the center.  As the wing naturally moves a bit this way and that way, the tiny pump would operate just enough to well positively inflate the air beam.
