 "secret power curves"   ????
A secret power curve may be faulty in many ways. 
An expert cannot examine a "secret" power curve of some entity. 
When an entity presents their definitions and methods of their operation and data collecting and how they used measures to produce a shown power curve, then an expert over power curves could discuss the non-secret presented power curves.  An expert on power curves would refrain from analyzing a "secret" power curve.

"The fact that kites can lift a weight was already well known for 100 years"
Is a zero missing on that "100" ?
   
  It is easy to see that lifting a weight shows capability of generating electricity.
So AWE for electricity generation has a sound basis for many more than 100 years.

Subject: Re: Moderator note
Joe I take your point, but I wonder if you're looking at both sides fairly.  daveS is the one harping on this "expert" theme in so many posts, going on for several years now.  He's obviously just repeating it, and including it in posts where it was not previously mentioned, to annoy people.  And I'm not sure if you've noticed it is difficult for anyone to post anything without him pretending to qualify or disqualify it in some way, whether he knows any real information bout it or not. 

Part of having a forum is to let conversations happen, not feeling the need to dominate them all.  At some point if someone keeps calling themselves an expert in a field, especially if just to annoy people, the annoyed people will be resistant. 

I realize you tend to want to come to his rescue and of course you can just shut down anyone who stands up to him, so I will just take a break for awhile.  Go ahead and have the forum without me posting.  I'll take a break and save you the trouble of shutting me down, and censor myself. Most questions I ask are never acknowledged or addressed anyway, let alone answered. 

Maybe you can explain why he can't show us a working AWE system if he is the world's leading AWE researcher.  Amazing to see such bragging.  It's enough to give one a headache just thinking about it.  This situation reminds me of Saddam Hussein's sons when he was in power: anyone daring to stand up to them was "shut down".

Hi Joe,


Please could you precise whom do you address, quoting ""secret power curves"   ?????"?


I saw this expression for the first time on the current topic (I put now the correct message, deleting my previous post):

Ampyx is another case of secret power curves (across all winds) I met the founders in Leuven, and find the venture to be naturally missing milestones based on naive assumptions, but also wildly successful raising investment. It cannot be claimed lack of funding is to blame for poor prospects of rigid airframes in AWE.


Rigid kites are desperate fliers; "clawing" in low wind. Soft kites are proven from sport to ship size, and can ghost along in low wind. We need rigid wing AWE testing to settle claims. People have to see the crashes and do the math.(DaveS).

Subject: Re: Reply to Doug's post// Re: [AWES] Re: W = m * g (NASA syntax) v

Doug, you continue to put up false things about DaveS.
He does not "brag" about his expertise. He includes himself among the populated collection of experts that have been developing AWE.   His generated electricity has been meaningful to himself and others. His generation of kite systems that do works is a faithful flow of AWE.  

He has not claimed to be the  "leading". 

He has estimated that he has probably done more variety of AWE experiments than anyone; he was open for someone to report greater variety. That openness is still extant.  No one has reported more variety of AWE experiments than he has reported.   It is my hope that someone will outpace him in variety of AWE exploration.  Let the race continue.

Please stay only on technical argument and veer away from the person-judging space.  Thank you.

Having a patent granted does not prove "original inventor" absolutely.
Having a patent granted puts a claim up for contest; during some contests, prior art may be proven. 

Floating platforms holding wind turbines is very ancient art. Specific new detail claims are surfacing that might advance the ancient art.  A new topic might be started to face some particular specific claim in that realm.

JoeF said:"That he did not immediately do the research for you is no evidence that he could not come up with one."
DougS Replies: Joe he described some super-hot competitive market of  20-kW products jostling for number-one.  I did not ask him to do any "research".  I just asked for him to flesh out his statement by giving a single example.  Obviously, from his description, he would have to know of some examples without doing any research. 

Now, I am trying to leave your forum for awhile, and you keep nitpicking in your own way.  This is where you two transition to the "I'll hold him while you hit him", tag-team mode.  I liked it better when you were publishing "Low and Slow" which I saw a mention of just yesterday. 

Meanwhile, why not find out what KPS is up to now, and fill in that conspicuous blank spot in your AWE infotainment knowledge-base?  Do facts have a place, or just fantasy?  Are you interested in outcomes, or just archiving empty promises?   It might be nice to follow up on previously promoted material before giving too much attention to the next one.

From what I have observed here, Santos makes outrageous and snarky claims that DougS rebukes and Joe goes out of his way for some reason to assist DaveS instead of addressing his snarky and overall unhelpful prose. I thought this forum is about was about sharing ideas but seems to be a waste of time. Instead of bickering, how about we see what you've been working on recently.

Please present the claims; then deal with the claim on a technical level; argue against the claim or for the claim.  While making the claim or statement review if there is any tone that would be best left out of the claiming.   I do not want to take time in forum for these reminders. There has been need for change in many posters' flow as regards personal hits.   
     Use the word expert, just stay away from personal attacks.   When countering something take ownership and speak not for another when permission has not been granted; one may argue:  "Here is why I hold that you are or are not an expert on __________:  etc."  and then argue on certain premises to a conclusion.  For instance, we cannot know the hidden intentions of a writer; if we guess at a motive, then own the guessing; if you cannot know for sure, then the matter is a guess; there are many other possibilities for using the word "expert" other than to annoy others;  I state that I have not been annoyed by the use of the word "expert" but read that DougS states as though it were fact that there has been intention of bringing on annoyance; it would be a different conduct if Doug stated: "It is my personal belief that the writer uses the word "expert" just to annoy others."   No one can argue with Doug's belief; one might are what he believes, but not that he believes.
 
     DaveS refers to expert views in a way that may be argued for or against; but during the arguing, please do not attack the person, but stay the course with logic and allowance of alternative perspectives.

Bottom Joint System
=====================================
Abstract:Minesto is developing a 100kW marine energy converter in form of a subsea kite tethered to the sea floor. Minesto’s Deep Green technology generates electricity from low-flow tidal streams and ocean currents by a unique and patented principle similar to a stunt kite flying in the wind.
In order to precede the development of this power plant, Minesto requires a Bottom Joint System to mechanically connect the tether to the Foundation. This ITT set out the requirements for the Bottom Joint System, were (sic, where) Minesto are looking for a contractor that has knowledge, skills and ability to provide Minesto with a concept, detailed design and fabrication of the Bottom Joint System.
See additional documentation for detailed information.
Please visit the website www.minesto.com for more information regarding the system solution.

We have to reason by analogy, so Ampyx rigid wing AWE will tell us something about all rigid wing scaling prospects, including Daisy variants.

All online communities struggle with operational issues. The AWES Forum has done as well as hoped in sharing kite knowledge no other source has. Developers who can't bear the annoyances miss a lot of value.

Subject: Re: Soft vs Rigid Wings
Thanks for noticing what's been going in here, Chris Harrell.  And fair enough, Joe.  I'll try to be more tactful in my choice of words if it will make you happy.  I still think, as a former math major in university, you might consider all those years of working around an "equals sign":  =  that people should be treated equally by a moderator.

It's interesting that a "more privileged" person posting can call the most pivotal and well-respected wind energy theoretician in history "stupid", declare his contribution unoriginal and invalid, and call him some other really nasty names, even ascribing questionable politics to him, while throwing in the towel on having any meaningful input to the topic of "double betz", without any admonishment from you. 

In all my years of wind energy I've never seen such an abusive dismissal of Betz, keeping in mind that Betz-bashing is the first and most well-known warning sign of a crackpot in wind energy.  Of course, it is true that Betz doesn't apply to people who don't practice wind energy.  I can only agree that the Betz coefficient does not apply to daveS.  How could it?  Interesting how a diversion into alleging the politics of Betz does not receive an "off-topic" warning from you, Joe.  Also interesting how easily you two attempt to angrily discard or invalidate facts, while happily promoting fantasy.  It's almost like a battle of good versus evil.

So Betz didn't come up with his own theory, according to daveS, and patents in general, let alone mine, are invalid when issued, according to you (Joe), as though examiners don't check prior art, while it never seems to occur to either one of you that smarter people than you - actual experts - have vetted all this factual matter, over many years, as valid and true.  You two have no problem making such declarations and even worse ones, all day long, while you endlessly scold others for their mere choice of words, being "off-topic", etc.

I think in some ways you've done an excellent job founding this AWE forum, and am grateful for it, but I also think you both stray way too far into thinking you know everything, when in reality, your knowledge is very incomplete.

Way back ten years ago, I got excited at what you two were doing to promote airborne wind energy, but noticed you two exhibited many of what I had slowly realized, over ten previous years, were symptoms of wind energy crackpotism, but assumed that with a little proper information, you could be coaxed into coming around, nudged gently into the reality of how wind energy really works, by describing these known pitfalls, so as to enable you two to avoid those pitfalls.

However, though I had been designing and manufacturing wind energy systems for years, with one of the only working AWE systems in the world, based on research funded by The California Energy Commission, instead of being warmly received as a helpful provider of knowledge, I was ridiculed and told I did not know what I was talking about, and that the typical, well-known disproven crackpot notions were in fact valid and the basis for improved working systems.  I'm a hopeful, positive person, so I tend to never want to give up on anyone, but you two often seem, well, hopelessly hopeless, with regard to ever making any sense, from my perspective.

Once again, you've trivially attacked my choice of words, because I mentioned noticing Rod Read wasting a lot of effort listening to the wrong people.  You say it was wrong for me to use the word "wrong".  Well Joe, I respectfully disagree, and please allow me to explain:

I saw hope in young Roddy, when I saw that, as opposed to the 50 or more previous failing or destined-to-fail teams and projects, Roddy in many ways "got it".  He reminded me of me starting out, because I had also started out using 3-D rendering to begin communicating my ideas more effectively.  I saw that Roddy understood the general idea that an effective AWE device could logically resemble a tornado, in some sense.

Now daveS had taken the position of negating and even ridiculing hard wings for energy extraction, instead promoting single-skin cloth working surfaces, whereas I, with years of experience extracting said energy, knew that even hard blades quickly wear out, and that single-surface cloth blades were rendered obsolete by permanently-shaped airfoils over a thousands years ago, based on performance.

daveS also promoted "worship" of "kite-Gods" insisting that these kite-Gods would solve the riddle of how to get all that energy down to the ground where we could use it.  When I read that Roddy had traveled to New Zealand to meet Peter Lynn (if I have that right?), my only thought was that he was taking daveS way too seriously.  Say what you want, but that's what I thought.  I imagined how many pilot-lifters Roddy could have bought online for the money such a trip must have cost.  You don't have to know everything about every person designing every component to do engineering, you just need to know where to get them and how they can be combined.

Now I know you guys are sometimes resistant to them, but I'm going to mention a few facts here, OK?
fact 1: daveS promoted cloth "kite" blades for energy extraction to produce electricity;
fact 2: I love kites, but advised hard blades for energy extraction to produce electricity;
fact 3: Using cloth blades, with 3 rotors, Roddy's "Daisy" AWE device generated about 300 Watts
fact 4: Using hard blades with only 1 rotor, Roddy's "Daisy" AWE device generated over 1000 Watts
fact 5: Therefore, the hard blades worked nearly 1000% better.
fact 6: Based on that, I expressed the valid opinion that Roddy had listened to the wrong people.

See?  Not that complicated.  Nothing mysterious.  Just Roddy's choice whose advice to listen to, and he made the wrong choice.  Then he realized he had made the wrong choice, expressing excitement at how much power he expected to make, as he prepared to transition to hard blades.

What you two seem to endlessly want to do, in my opinion, is hide in a world of fantasy, while avoiding reality.  You're happy to assist entrants to the field in promoting promises of how many hundred houses, or whatever the number might be, in given locations, by given dates, but actively resist any followup when the given dates roll by. 

Going back to that equals-sign = from the world of mathematics, your major in university (Joe), why would we not express an equal amount of curiosity regarding the actual results of such programs, as is directed toward their almost universally-false initial statements?  Did you realize real wind energy people give zero (0) credibility to empty promises of improved wind energy devices?  That power produced is the only thing that matters. not false forward-looking statements of fantasy?  That we've seen hundreds of "on-paper breakthroughs" come and go with no result?

I have to say, given the amounts of power I've read were produced from various AWE prototypes, I'm increasingly perplexed that out of something like 50 or 100 companies, none seem to be bearing fruit.  A few years ago, I was believing these power production figures, but lately I'm starting to wonder where these numbers came from, and why we don't see several systems in daily operation, proudly publicizing their output on a daily basis.  But, while hopes may be dashed, you have to pay attention to the trend.  While nobody would expect all the projects to succeed, few of us expected all of them to fail.  Are they?  Sudden "radio-silence": We can't be sure.  So all we can do is guess.  Unless someone was curious enough to bother to find out any real information.  Anyone?

You know the difference between this forum and a previous wind energy Yahoo forum?  In the previous forum, the participants knew something about the facts of wind energy, and people who came in and bashed Betz, etc, were not only far outnumbered (as opposed to running the forum) but seen for what they were: people without the requisite knowledge.  We'd tend to sometimes just label them as "idiots", etc. at some point, if they became obnoxious enough - please excuse the French.  Not that there's anything wrong with not knowing something, but not knowing something while saying you know better, when you don't, gets into that special zone that calls for special descriptive terminology.  The majority of people on the group practiced wind energy, so they actually knew what they were talking about.  The moderators were actual, well-known, recognized-by-peers, experts in wind energy, though they never felt the need to call themselves experts, since it did not need to be said.  Their expertise was obvious, and spoke for itself: They regularly designed and built wind energy systems that powered peoples' homes.  Facts speak louder than words.

OK thanks for reading this and now I'd like to get back to taking a break from this forum for awhile.  So please overcome the urge to "have the last word".  Maybe take a while to think over what I've expressed here and see if, possibly, you guys would like to become devoted to facts versus fantasy, and spend as much attention on results, after the fact, as on the empty promises bereft of facts, we tend to hear every day from this venue.  Allow yourself to feel, then fulfill, the need to "follow up" on the stories you repeat and publish.  Try to be a little more humble when describing your own supposed level of experience, understanding, and ability.  Consider your results, compared to the results of others, when assessing your own level of expertise.  Remember, facts are your friends, even if at first you don't want to hear them.  In wind energy, to ignore known facts is the quickest way to failure.

Agreed. Christian seems to imply he has (or should have) more than Netiquette opinion to share with us. When we last followed his work, he was refining his Orbital Kite Theory and developing AWES prototypes in the low-kW range. Given his very promising start, he likely has new insight to share.

Subject: Clarifying AWE Expert Questions
The original root of the word "expert" is "to try, test", and came to mean "wise through experience"*. In AWE, a growing list of folks qualify to varying degrees as true experts. The question is not, who are the experts(?), but what should they know(?)

My opinion, that competing AWE ventures should not presume KPS is dead in the water if its announcements seem to lag, is simply the precautionary principle common to experts across countless domains. To not guess the worst of KPS is just reasonable business heuristic expertise; no wrongful claim to undue AWE expertise.

The controversy over what constitutes AWE expertise tends to break down into aviation-kite experts v. non-experts. Those who have kite-pro, aerospace, HG-PG, sailing, and like backgrounds, are seen as having foundational AWE expertise, in an elitist view ("The Right Stuff"). In the opposing view, any such expertise hardly matters, there are no real experts, or maybe the experts are those who work for the best funded efforts, who do not reveal their expertise freely. Some even argue that AWE academia and other AWE knowledge elites are not experts at all (ie "all crackpots').

I side with the aviation-kite pros, and claim limited but respectable expertise in kites and aviation generally, while agreeing that specialized AWE expertise is still rapidly developing.

Caution is required in calling claims to expertise "outrageous". Outrage is an extreme emotion inconsistent with expert cool-headedness. A claim to expertise is best tested carefully and fairly, point-by-point, without outrage.

* Dictionary.com-

Word Origin and History for expert. adj. late 14c., from Old French expert and directly from Latin expertus, past participle of experiri "to try, test" (see experience). The noun sense of "person wise through experience" existed 15c., reappeared 1825.

Subject: AWE's unhappy also-ran ventures?
A historical paradox of major technological success is the large number of losers, often called "creative destruction" in capitalist ideology. In AWE, our list of failed ventures grows, even as the field advances and even more new ventures pop up. A key goal of this Forum is to help prevent a winner-take-all dynamic, by making AWE knowledge public before it can be privatized. Its even been advocated here that losing players be compensated in future revenue, as everyone feeds on the lessons of their errors.

Its painful to see some friends' hopes dim by the day. Generally, their fatal flaw is a premature architectural down-select on pet ideas. In first seeking a business advantage, they did not see themselves as part of a common test-research community, where everyone matters, so its particularly humiliating when they fall short. No need to list such players, and further upset them. 

On the other hand, the happiest players are those who see kite research as a pure knowledge-quest, who find joy over years of R&D. AWE R&D is in fact a paradise for those players, and win-or-lose in business hardly counts. The happy players enjoy whatever they learn, eagerly seeking the next lesson, while the unhappy burn out. I recall an unhappy player at HAWPcon09, who suddenly turned against Wayne German, who was simply having too much fun. Since then, a bitter cohort in our ranks is more-or-less constant.

What's been lacking in AWE is the sort of inclusive leadership lost when Wubbo Ockels died. The sense that we are all in this together seemed to die with him, but future rounds of more open R&D could finally bring most everyone together again. Meanwhile, unhappy players may get even unhappier. Let them not forget Wubbo coined "Happy Energy" for an AWE synonym.

Please also consider, longtimers of this forum, that someone once mentioned that searching the forum would be a resource of AWE information. The quality of that resource is closely related to the signal-to-noise ratio of the contents.

No-one is interested in what education people have, what happened at some conference years ago, who did not deliver on their promises, who is «anyways wrong» with little in terms of argumentation.

Lets keep the messages on the topic of technical AWE, make sure anything posted adds additional _technical_ value, and «dont feed the trolls». I am not implying that anyone here is a troll, just the notion of just letting some non-important stuff pass unanswered.

AWES Forum discussion does vary, but the signal-to-noise ratio never does settle "near zero". Even as some cannot handle much noise, for whatever reason, the deeper motivation is to not throw away any "golden needles in haystacks". Fortunately modern search tools overcome troll noise, or we really would be in trouble.

It would be nice if everyone here was collegial, but we have a far higher obligation to focus on AWE for moral reasons of energy technology in crisis. If a doctor can tolerate the deliriums of the unwell, so can we, in service of our higher goal. Let other Forums moderate more strictly than JoeF, whose tolerance has been heroic; almost divine.

The more AWE forums the better. We need forums where rudeness is absent due to normal moderation, and folks only act friendly. We need forums where rudeness is the price of greater openness. The most civil language in AWE is empty public relations by those who most control capital. 

This is the place where AWE venture secrecy is answered by more-or-less expert speculation. A basic test of intelligence is when a mind is aware of hidden mysteries and seeks to theorize. This is the place where such theorizing thrives. We are under no obligation to keep any venture's secrets, if open AWE knowledge is the highest path.

Ultimately, AWE forums should be judged on merits. The highest merit will apply to content that was original and significant. Other Forums have a huge way to go to equal the accumulated merits of this Forum scattered across tens-of-thousands posts over ten-plus years. Trolling has not prevented getting this far. In fact, we have used troll frisson to hone worthy counter-principles.

A large portion of AWES Forum content is real news reported first or nowhere else. This hard work most critics do not bother helping. Critics are answered with scant regard for "don't feed the trolls" theory. Those who must look away surely miss out. Those who have faithfully followed the Forum all these years are more expert than those who never have.

AWE is the most fantastic endeavor many of us have ever found. Moderation woes are simply too trivial to matter as much as the sheer wonder of AWE. Flying kites more is our special antidote for petty concerns. The glorious outcome of AWE will put social media complaints to rest. In the end, we are all friends here, despite our disagreements.

May we not speak for others without proof that the others hold to what one states; just self-own the statements that one makes; wait for others to give there position. 

For instance, in your considered note, some alternatives: 
1. Historical process may give food for forming next motions and acts.  There are indeed some of AWE community who are definitely interested in raw biographies of some AWE adventurers including details like background, education, sources of learning, philosophy, and more. There can be clues to AWE technical matters when a robust view of a worker is known. 

2. How one builds or retains interest in something may depend simply on decision to act, to maximize use of tools, to invest with focus.  Stability of focus may pay dividends unseen.  Building interest via decision is a choice and option. Those posters who decidedly use tools well and their time well may add solid positive value to most any forum.  A poster who decides deliberately or by neglect to slide away from opportunities at hand will probably lose positive connective relation with the contents and content potential of any given forum.    
_____2a.  Stability?  Growing the flowers where planted without uprooting them over and over again?
_____2b.  Forums come and go.  One may look for the presence of stability aspects of a forum.  

3. It is thought by some that most any forum on any topic anywhere on the Internet will have challenges that shake foundations. 

4. Stay open to the potential that there may be several helpful AWE forums. Indeed, such is the case already: hang gliders, paragliders, KiteLife Forum, AirborneWindEnergy, and much more. Many hundreds of kite-system forums exist; there is a huge garden of AWE activity on the Internet.     

5. Avoid the noise one does not want to mine for gem nuggets, even nuggets that may change the course of AWE.  One little nugget may key a new branch of AWE or lead to a core solution of something.  There is a wide variety of questions, challenges, opportunities, potential service sectors, and  problems in airborne wind energy, even some that have yet to be mentioned in the literature.  

6. Refining search skills is open to anyone, no matter signal-to-noise level. Any reachable file on the Internet that is searchable may have AWE gems; those gems are invited to be pulled into this forum and the forum's serving files.  Neglect to sharpen one's search skills has its natural consequences.

7. Some workers in this forum will search the hundreds of AWE forums for nuggets for presentation for discussion.   Any new forum will be simply another source for AWE nuggets for inclusion in this forum and its support files and folders.   

8. There is no need to "save" a forum.  Participate and life continues. Be absent here and active elsewhere will simply provide AWE matter that will be brought back here, as such is part of the dynamics of this forum. Links and abstracts and quotes, etc. will keep a growing of the core of this forum.   No need for anyone to sour any AWE effort; just grow where and how one grows best.   This forum will recognize good AWE matters wherever such matter sprouts.   

9. People's attention is a gift. May some people attend to growing AWE !

10. Analysis of good or poor arguments may provide a sharpening of next arguments.  Analysis of apparently wrong technical directions may provide a rich source of information that may help carve out the next round of effort. 

11. An open forum will receive and show what posters place.  This forum trusts its posters to post well and in fidelity with policies.  What then gets up in a message may be a mixed bag with some non-AWE matter and some disturbing matter. It is encourage to stay on topic as much as is naturally possible.  The importance of matter posted varies.   One may carve out one's own path through the forest.  And one need not comment except when intending to add value to AWE.  Posters each have their own style and personality.  Appreciating varied perspectives may enhance the community.   

12. The AWE community has many focal arenas. The count of specialty arenas is still increasing.   Tether experts may have a forum.  Anchor experts may have a forum.  Kite farming may have a forum. Application differences will generate forums. Scale of kite systems generate specialty forums. Electricians serving AWE may have a forum.  Etc.   Each forum may be respected for what it is.   

Post in 30 AWE forums or just 10 or just one or maybe none.  Find one's interest and perhaps aim to advance the communities that seem to fit one's blossoming.     This forum will find you if your presence is noted on the Internet and you are growing AWE.

Subject: AWES Critical Factor Categories (Review & Update)
It has long been known by leading AWE experts that there are multiple critical dimensions to large-scale AWES design. Many complex factors have were first introduced and extensively analyzed here, but deserve regular reviewing and updating. There is overlap and interdependence between many critical factors, causing some redundancy to comprehensive listing. Here are the top Critical Factors, by category, with many embedded critical factors in the details*-

Safety: AWES must operate within all applicable safety standards, like FAA regulations.

Reliability: AWES must be reliable enough to survive to capital pay-back.

Performance: AWES must have a high Power-to-Weight factor in Most-Probable-Wind Velocity.

LCOE: AWES must have sufficient economic performance to succeed.

Desirabilty: Wubbo's criteria that we designers can choose what sort of AWES we want, not just the most utilitarian solutions.


Can anyone add to these five primary categories of Critical Factors? How about any overlooked critical details?

======
* For example, AWES Safety has a long list of critical sub-dimensions, like sense-and-avoid air traffic, breakaway risk, design for frangibility or crashworthyness, electrical risks, insurability, etc.

The new Forum is succeeding. It hardly seems worthwhile to export the Old Forum's problems, but its massive archive is available for mining or mirroring. I will stay away from the New Forum for now, to appease complaints about my posts. I will comment from this Forum on specific questions (like how free reeling motion can be supported from a static pilot-lifter by rigging a reeling cableway and elastic leader under the pilot). 

Good Luck to the New Forum, with all its fresh energy.

Subject: How to combine Reeling Motion with Static Pilot Lift
On the New Forum, a known problem was stated: "The lifter will put a heavy toll on your efficiency for yoyo/lift based AWE."

kPower/KiteLab-network solution- Free reeling ("yoyo") motion can be supported from a static pilot-lifter by rigging a reeling cableway, plus elastic leader under the pilot kite to buffer power-kite pattern motion, in a balanced dance (the elasticity returns energy to the power-wing sweep pattern, the pilot does a nice little dance, with some reaction sweep, but no jerking). 

Re: Efficiency, adding pilot-lift this way enhances efficiency of any existing reeling scheme, since pilot-lift has inherent high power-to-weight to offset mass penalty of the working power wing part. This is especially helpful in lower wind conditions, to maintain some AWES output. A pilot-kite also offsets active control requirements (mass, power, and high cost).

Subject: AWES Complexity Theory- KIS not dead, M600 may soon show
This is a revisit of Engineering Complexity as a predictive lens in AWE, occasioned by Makani's looming M600 test program in Hawaii.

The best metric of engineering complexity is topological; given by part-class count, not simply counting identical parts. Mathematical complexity is a field in itself. Engineering complexities occur anywhere, like social, operational/situational, modeling, and manufacturing complexities. Tracking complexity in AWES architectures is perhaps a sound predictive basis of TRL success. "Keep It Simple", the engineer's timeless motto, is about to be dramatically put to the test, in AWE, by Makani's Hawaii testing. The M600 represents extreme High-Complexity AWE, a massive 85ft WS autonomous aerobatic E-VTOL composite-airframe multi-flygen platform. 

By comparison, kPower stands for Low-Complexity AWE at the KIS extreme, of "Rag and String Only", of power-kites and pilot-lifters as long proven. kPower emerged from Makani (via Culp and Santos). Its really one big power-kite family, that includes SkySails, various small ventures, and the kite-pro class. Of course, Makani simplifies wherever it can, and low-complexity AWE complicates as necessary. Somewhere between the two schools lies the sweet-spot of future AWE. Low-complexity is playing black in R&D chess to Makani's high complexity white, playing to win.

No amount of venture capital likely negates the winning advantages of low complexity AWE, building on millions of hours of power-kite and classic-kite practice. All technologies start from KIS rudiments and over time integrate complexity. Makani's architecture will do wonders someday, once graphene, super-conducting electronics, and perfected automation all come together. For now, its the simpler ship kite that's the most proven AWE WECS unit, the KIS champ. Makani's return to Hawaii testing should reveal to all how well the intricate M600 compares to documented power-kite performance, safety, and relative capital efficiency.

Even if Makani does not reveal Hawaii test data, we have our spotter (Roel Gorena) in place, we know how to estimate performance from videogrammetric clues, and any major mishap on that island will be noted.

Subject: Why Flying Wings are Bad Kites (esp. "Prandtl Wings")
On again commenting on New Forum discussion from Old Forum knowledge:

Let flying wings be defined as pure wing with no tail or fuselage; in powered flight originating with Dunne 1910. Such wings are lowest theoretic drag but poorly maneuverable. To execute a turn requires two steps- Roll (slowly), then Pitch. When the wing is tilted sideways, no fuselage is present to act as default horizontal wing surface for Sideslip capability.

Kites at the edge of the kite window depend on vertical surface to tilt into horizontal surface. Without such lift, they fall down. Such vertical lift surface is called "Keel", and adds some drag, but is as necessary as the dagger-board on a sailing dingy. High turning rate is also essential for competitive kite sports and vertical area is designed-in (esp. C-kites).

Many AWES designers fall into the flying-wing trap, like Makani Wing3 era, Enerkite, etc. They end up adding back vertical surfaces, like Makani's flygen pylons. Prandtl's 1933 work did not earn him naming rights to flying wings. He was a Nazi  scientist who worked alongside Betz, who also somehow usurped proper naming priority (from Lanchester, for the 16/27 ratio).

Subject: Re: Why Flying Wings are Bad Kites (esp. "Prandtl Wings")
Adding that a kite wing's "keel" area needs to be balanced just forward of CG. Just adding winglets to a flying wing makes crashing happen even easier, by added aerodynamic imbalance. If the wing is high enough or suspended, or the turns very big, less vertical surface will suffice. The ultimate goal is a balanced turn behavior, just like most aircraft.

Forward vertical surface also can create a tricycle landing gear structure with a high flare/stall angle, and also act as a "chicken-stick" to promote STOL/VTOL.

To the extent these standing claims on the AWES Forum are original and valid, they are part of the Open-AWE_IP-CLoud

Magical spirit evident. A few Watts at 4m/sec is good low wind performance. Most other designs do nothing in light air.

The broken part looks like a 3D printed polymer part with poor strength, not a big deal. Mild steel spars is a cool detail; after all, thin-wall chrome-moly steel alloy is a prime small aircraft material, with the same excellent DIY torch-weldability as mild steel. 

The spate of torsion AWE demos beg the question of how high torsion drives can effectively scale. kPower opinion is that scaling limits for most probable (low) wind velocity are already being pushed by all three cases (ST, Daisy, Tuddel) and further scaling will be marginal. A possible solution might be short turbine shafts aloft driving cableways to the surface.

The hundreds of AWE demos over the last two decades do not validate any architecture just by being the latest. Old demos are best compared with new on technical principles rather than dates. Nevertheless, great to see new AWE demos, and that torsion has its worthy representative players.

Congratulations to the Tuddelpower Team.

Subject: Re: How to combine Reeling Motion with Static Pilot Lift
One could always give the lifter kite depower ability. The problem does seem a bit difficult to deal with to me. You need some kind of energy storage. You can get free energy when reeling in by using a bungee/winch between your AWE rig and lifter kite, but you need to put that energy back later when the next production phase starts and the lifter kite needs to be reeled back in. A bungee is possible, but a bungee is not a controlled element, so there might be losses.

If you need a lifter kite, perhaps flygen or torsion transfer are better options than yoyo?

Subject: Re: How to combine Reeling Motion with Static Pilot Lift
Of course one can create a depower mode for a pilot-lifter, like WPI demoed, but its still an compounded parasitic factor to drag it back down during a reeling cycle, so this reeling-cableway method avoids that extra drag while maintaining simple pilot-lift flight. We have never before thought to reel-in a pilot-lifter along with its power-wing, as a unit, since that's even more wasteful than just reeling a power wing, already very wasteful. Its not just the powered drag loss, but the return cycle time. The quote from the New Forum is taken as true, unless a method as suggested is applied.

On this Old Forum, Northern EU popularity of Reeling down-select has been a mystery, while most of our schemes have been on non-reeling fully-crosswind load motion, esp. short-stroke pumping where a bit of elastic works well to return energy in the pumping cycle while buffering the pilot-lifter. 

The good news is the diversity of AWES approaches, so that every major approach is being fielded, and could be comparatively tested in a future shake-out fly-off program. No one can claim that Reeling is not well represented by the formidable EU developers, but can they beat pure crosswind motion as laid out by Payne, Hadzicki, Goldstein, etc.? They have made a big bet on Reeling cycles up and downwind.

A key KiteLabs finding, from many tested prototypes, as first shared here some years ago, was that a soft pilot kite holding up a rigid blade WECS is a highly optimal AWES design combination, for many reasons listed. This was not a new kite combination, just early testing and discussion in an AWE context.

Since then, we have had a run of this identified AWES pattern language, in various prototypes around the world. The basic pattern is fabric-based pilot-lift for both passive stability and mass-lifting of its rigid blade WECS payload. As the practical limits of a large brittle WECS wing kick in around 100kW, far larger rigs can still be developed using parafoil power wings, whose prime virtue is to progressively pressurize with velocity, to be as rigid as needed when needed.

Virtually all AWES demos that rely on a soft pilot-lifter kite use it to carry a rigid wing WECS. This looks like an emergent Darwinian Winner in AWE architectural exploration that was predicted here on the principles of cheap passive autonomy and minimal airframe rigidity matched to apparent wind velocity. The follow-on prediction is that this combination of soft-lift and rigid wing WECS will extend to kite networks. The pilot function will be replaced by the topological stability of the network over an anchor-field.

Subject: Feared Enerkite Failure
The video news coverage was upbeat; Enerkite was preparing to launch its kiteplane from a rotating arm for the first time. A nervous investor was present, the cameras were rolling, but the intended maiden session was suspended due to technical difficulty. The coverage ended at that juncture. MaxB expected to have the prototype flying by the end of October. Then...nothing, no news two months since. The Enerkite website offers no clues.

Once again, we are left with engineering speculation, given AWE stealth-venture imposed uncertainty. Was there a crash? That would explain the silence. If there was a crash, was it due to the stability problem of unbalanced vertical surfaces, as previously noted? How long would a crash set back testing? No backup kiteplane was seen in the shop. Did weather and logistics not cooperate? Was the catapult simply too slow to throw the kiteplane far enough into the sky? Was control too brittle and crude to handle the delicate transition from shortline instabilites to longline flight? Was any critical flaw technical bad luck, or worse; the inherent architectural limitations of Moritz's rotating launch method?

Lets hope Enerkite bounces back with whatever improvements are needed, with an eventual accounting for the mysterious delay.

Subject: The Sky is Falling- Drones shaking the world
Thoughtful and troubling. The Sky is changing before our eyes. Drone defense; the hot new kite app. As we polymerize the Sky, drones will cut our lines. Drones and kites are crossbreeding. Lines in the sky is the prophesized "third shaking of the Earth". Run, run like the wind.
