Ed Sapir is a new talent in AWE, not a figment of Doug's imagination like "Professor Crackpot".

The video Ed shared is very true to the day-to-day progress in AWE. Field experiments tend to hang maddeningly on small details, with much danger and comedy evident.

For those who study technical details, note the better Pilot Lifter sled over the 6m2 parafoil SpinKite. We were trying to close up the swept loop by resetting parafoil four-line settings, but negated the change by setting too-long a leader on the new Pilot (over-caution to moderate the surge-load that collapsed the big delta).

My hope is that a phone-cam audio trace caught the continuous cycling of the groundgen, since the hand cameras did not visually record flywheel spinning when pointed at the kites. Our tripod camera had timed-out due to a high frame-rate setting. We had vowed not to miss session action by setting up this camera, and we still lost it. The best moments are camera-shy.

The session nicely revealed small groundgen design-flaws. Improvised unit anchoring with a T-post soon precisely jammed the flywheel, by Murphy's Law. The simple drive-belt fairlead (no rollers) had tended to bind when pulled off-axis, so the improvised stand-off pulley fix pulled out of the ground, from powerful kite surging, to flail its T-post anchor menacingly around our heads (another off-camera near-death experience).

The loud whining heard was the temporary cordless-drill DIY-style generator. The whole drive-train amounted 50-1 rpm step-up, and was likely about 3-500W in "ratable" terms, but we have a quality generator to swap in place, for a target rating of around 1000W for this prototype. In a medium breeze, the kite rig throbs with excess power, and we can fly a larger kite rig as needed. 

This is pure engineering-science, as artful play: The machines are fine sculpture. Production design is emerging in follow-on versions still in the shop. Eventually AWE will be boring.

The kPower business advantage to such honestly futzy video is to lull arrogant competitors into false security. But the day finally comes, after near-endless practice, for true mastery to manifest...

Sorry Dave, you should look it up.
Down in MazATLAN, they were still using atlatls.
You're entitled to your own opinion, but not your own facts.
One reason I point out the ATL connection is it shows once again the ignorance of humans:  the idea that an ocean could be called atlanTIC while denying that on the other side is atlanTIS.  Especially when you get there and almost every place name and even the name of the language feature that same ATL sound.
Basically, almost everything you say is simply wrong, as many have noted.
OK so "Edioshi" is Ed Sapir?  Is that the same guy you sent to visit here with his bicycle invention?  A nice enough guy.  "His writing" seems suspiciously the same as yours though...
So do you think you will solve airborne wind energy, or get killed by one of your attempts first?
Have a day!

The AWES Museum freshly made available some other rooms that were not announced priorly on its front page, but here post for access and news notice: 


=========== 


  •  
  • The museum room dedicated to the "lines" of AWES is KiteLines.  As AWES have three major sets of essential parts, the line set or tether set being one, a dedicated museum room has been growing. Interested persons are welcome to visit and advance the collection of studies about kite-system lines.
     
  • An increasingly visited room of the museum is that which is dedicated to knowing the types of kite-systems known which become possible players in AWES.  The public is invited to describe new found kite types and discuss them. Access to the room is free.   KiteTypes.
     
  • A room of the museum dedicated to flip wings keeps drawing attention. There are yet many things to be added to this collection. And the public may help curate the collected items. Access is free.  FlipWings
     
  •  

===========


Updates will be posted at the AWES Museum front page

Visits to the open rooms may be made at one's convenience. 

Visits to the brick-and-mortar rooms are by appointment only. 

Participatory construction and furtherance of the museum's mission may be achieved with even small sendings of items related to airborne wind energy/kite-energy systems.

Pierre,

Dr. Fort Felker, Director-NREL, as a veteran top-scientist in wind power, did not propose that "Test, test, test, etc." is for monkeys. The monkey-at-a-typewriter smear is your unfair misconception of what real test engineering is. In particular, kPower is carefully validating COTS sport and hobby kites for AWES use, with very few really new ideas added in. This is no job for your imaginary monkey-typist bogey-man.

There was a properly nuanced recognition by Dr. Mark Moore, NASA LaRC, that our AWE community is in fact rapidly creating solutions like a genetic algorithm, as he tore into Mike Barnard for his incredibly ignorant dismissals of this natural dynamic. Surely you saw it. Our testing diligence is not a wasteful negative, like monkey-typing or anti monkey-typing. If you are not testing, you are falling behind those who do.

Please note-

Joe as I recall, you are into hang gliding?
Do you ever get up to the launch site at CedarPines Park near Crestline?
That is not too far away from here.
We go up there sometimes just to watch.
If you're ever planning to launch from there, call me at 714-749-3909 and we will see if we can come up and take a few pics.  We get some good ones.  I'm trying to decide if I should get back into hang gliding except it seems I'm already spread too thin with more interests than time to pursue them all.
I used to have an Eipperformance Rogallo hang glider with a 4:1 glide ratio in 1975 or so.  I was just a kid.
It was fun, like sledding down a hill, making a few turns, but nothing like the performance of today's hang gliders.
Seems like one popular glider manufacturer today is Wills Wing based in Orange, CA.
Many of the kites at the CedarPines Park launch site are WillsWings.
I used to sell the people working at WillsWing speakers out of my van years ago.
What's your story with hang gliding these days?

Subject: Re: The almost complete lack of intelligence of humans

It is interesting to note the ideological part in AWE. In one side "progressivism" and spirit of "sharing" and also "tabula rasa" associated in little expensive soft materials and new (or very old) ways of conversion. In another side "conservatism" and spirit of "individual" and also historic inheritance associated in rigid blades. Another interesting thing is the common reject (but for various reasons) for utility-scale of the actually most prominent forms of "crosswind" systems from people so different as DougS, DaveS (perhaps excepted for some configurations with passive control), Barnard Mike, RodR, me. So two families remain to explore: rotation  (for Doug,me, Rod,maybe others), and oscillating with short strokes (for DaveS, Rod, maybe others). It is a progress by elimination.

Wait a minute!  I thought the "monkey at the typewriter" smear was MY smear(?)
Or, maybe "comparison", "example", "metaphor"? - OK you call it a "smear"...
Whatever.  Endlessly trying to rationalize every wrong move by adjusting the entire English language around your missteps and misstatements....
Dave can I just say:
You make about as much sense most of the time as that guy in the video:
http://www.keanwindturbines.com/
Note how he can't stay consistent for even a full sentence?
How long do you think it would be before he cited "The Wright Brothers", if challenged?
Why don't you try "debating" him and see?
Use a stopwatch.  Record how many seconds til the moment he goes into "WrightBro mode".
Oh wait - for you, there would be nothing to debate.
You probably can't identify anything wrong with his design, or the claims he makes.  It probably all sounds eminently sensible to you..
It seems to agree with all your theories.  Maybe you should test it.
type type type!

I hate to admit it but I grew up in that general area and OMG it seems so backward now, like watching someone in some stuck-in-yesteryear, old-world country, where they still use oxen for transportation.  Wait, let's give him a break - he may have the technical details wrong, but what an articulate, sharp dresser!  A mover and a shaker!

Doug,

Of course spear-throwers existed, no one has asserted otherwise.

The point was how falsely you claimed, off-topic, that Columbus found the bow was unknown in Atlantis. The guy who makes up facts here is you.

Please get back on AWE as such, when you have something worthwhile to add,

PS AWE experts know how to vet AWE frauds far better than you can (by testing). The real work is to create AWE solutions, not just rant over endless wind frauds on poles.

Subject: Re: Inherence v. engineering
DougS, 
     AWES convert the wind's energy into other forms of energy able to accomplish certain works. 
One corner of AWES has to do with lifting mass; sometimes that mass is a human body;
sometimes that human body is a holder of decisions that may involve decisions to control the AWES's arrangements during flight. 
One such system is the kite hang glider. As curator of AWES Museum I continue the work of the founder of K.I.T.E.S.A. concerning kite hang glider history technology. The extension includes research, development, and publishing. The publishing includes growing a major hang glider Timeline. Of course various manufacturers' stories show; Wills Wing is certainly a major player; I have flown recently several of their kite hang gliders. My last visit at the launch at Crestline was two years ago. Though I co-founded the USHGA and assigned with agreement with Eipper my membership number "#5" (to me, family and community poetry), my recent two years of USHPA membership found me mismatching with the org sphere that is practiced.    Kite hang gliders and powered kite hang gliders are destined to play increasing roles in AWES culture for surveying, testing, inspection, maintenance, advertising, photography, ...        Thanks for the invitation treasured.

DaveS,

 

"The monkey-at-a-typewriter smear is your unfair misconception of what real test engineering is."

Mixture! I did not speak about monkey or about my conception of test before now, for stronger reason of any link between monkey and test.

 

""Test, test, test, etc."" It depends on what we want to test, and for what target. But I admit it is better to test shemes having no chance to go towards real production than testing nothing. It is yet better to describe a sheme with its conversion system before testing it.

 

"There was a properly nuanced recognition by Dr. Mark Moore, NASA LaRC, that our AWE community is in fact rapidly creating solutions like a genetic algorithm..." For what I understood a genetic algorithm is not a solution for AWE but here allows to find AWE solutions. Mike Barnard wrote about existing AWES and their lack of potential due to numerous challenges, and Dr. Mark Moore wrote about the possibility to create solutions and also mentions his own system: there is no contradiction, only a difference of perspective. By writing "Mike Barnard for his incredibly ignorant dismissals of this natural dynamic." you admit implicitly that Mike Barnard is right for his analysis of existing AWE.

Pierre,

Everybody agrees that AWE is not currently mature. MikeB is not criticized for stating the obvious. He is criticized for low standards in reviewing aerospace matters, as well as deep journalistic faults like his strong industrial-wind and nuke biases, technical censorship, Wikipedia sock-puppeting, and so on. He offers no productive solutions, which is how we judge value. You are critiqued for not accounting for these flaws, preferring to attack those who design and test AWES the most, sharing the most knowledge and art.

The KiteLab/kPower circle has designed and tested far more rotary concepts than you and Doug (and everybody else), so do not exclude us from your rotary club membership; just try to catch up. Of course we also test non-rotary concepts, comparatively, again more than anyone else, which you seem unable to admire :(

DaveS,

 

In a sense it is a satisfaction MikeB critics concepts (crosswind systems, aerostats) you, Doug, Rod or me do not precognize as utility-scale; for me these concepts have inherent problems. But MikeB critics also SWP of which concept looks good but needing engineering to make a simple (no cyclic pitch even at utility-scale) and lighter version. Mothra-Arch being built, now it is the time to implement the conversion system, knowing Arch is adapted in prevailing winds due to the two anchors. For the two anchored conversion systems I propose the following: Arch vertically rises during power phase reel-out on short time, and vertically comes down during recovering phase reel-in by using ground gravity . This configuration allows the Arch keeping the same position and orientation. You can describe another conversion system but I think the time is limited. In the same time I will study some configurations of helicopter-like, and if the description agrees,collectively bringing up corrections then building a small device and testing it.

Uhh Atlan is in Mexico, where they spoke NuhATL, not the North, where they had the bow-and-arrow.   The bow and arrow was not in use there in Mexico when the Western explorers arrived in, say, MazATLAN. or IxTLAN.  After they crossed the ATLANtic ocean.  Why do you think they call a dart-throwing (not spear-throwing) stick an ATLATL?  Because the people in MazATLAN, speaking NuhATL, after drinking some ATL (water), named it like everything eles in their language, ATL, and that is why it is called an ATLATL by everyone to this day!  Get a freakin' clue!  That is probably why you are so resistant to new technology - they were probably some of ,your ancestors!  Some say everybody used to know about American being here and the information was later surpressed.  The name "aMERica simply means "land across the ocean (MER).  Amnerigo Vespucci was named after the continent, not the other way around.  Others say people always knew there was always land on the other side of any body of water, lest there be nothing to hold the water in!  SUre, peole had zero IQ's then as (you do) today, but they weren;t stupid!  Well, sort of...
OK back tio AWE, that rotating parasail you have should be able to make between 10 and 50 kW.  I would counterbalance the rotating kite with an opposing, second rotating kite.  Some people would call it a (gasp!)rotor and they would call the kites (say it isn't so!) blades.  Then you need to find a way to get that rotation to a generator and it needs to be way bigger than an electric screwdriver.  Later you may realize that to drive that generator really well, you really want (need) faster rotation, and use lumber in an airfoil profile instead of kites.  Or I might point out that most  people these days use composite blades.  What you have WANTS to be a SuperTurbine(R). Of course.

    Pierre,

    We have many qualified expert engineering critics in AWE from key domains like kiting and aerospace. Its funny that only you and a tiny subculture of ignorant "industrial wind" promoters think MikeB is a competent AWE critic. Even he admits to only be a layperson with only preliminary superficial study to offer. There is not a single serious critique he has made that we had not already made years before, for example, in spotting Makani failure modes, a process which you complained about, without ever addressing specifics.

    You find in MikeB some otherwise missing social support for your weak " AWE not viable" thesis. To embrace him you overlook his low journalistic ethics, which were established before he began to opine against AWE, and before he was caught by us shamefully sock-puppeting Wikipedia. You and MikeB need each other more than the AWE science-engineering community does. He will not critique you, as his lone defender in our AWE circles, but try standing up to him like the PhDs do.

    At least try hard to create a small working model of your wheelwind concept. If you really think AWE is not viable, withdraw your call for investors. Show MikeB you are better than him; and one of us,

    PS "inherence" is a strange choice of wording (?)

    Of course the Aztecs had arrows, as Cortez's company documented. You are mistaken about pre-Columbian archery only being Northern, in fact the bow was common all the way down South America. Why Mazatlan would be a tiny pocket of archery ignorance is not clear.

    You are also a bit off about how much power a 6m2 parafoil delivers in a modest breeze. The key parameter is how cheap fabric wings are, and how quick they make pay-back. Be ready to compete in testing, if you can make a better AWES than kPower looping parafoils. Otherwise, you are just like the Kean Turbine promotion, unable to show convincing results, just blowing smoke,

    The personal attack issue is your non-technical distraction. If you would be consistent, complain about MikeB's use of the word "moron" on the AWES Forum. You cannot show where anyone, even our rude friend Doug, ever set a lower attack standard, nor do you bother to cite any particular personal insult directed at Makani, so it can be rectified.

    The prevailing domain-expert view on AWE LCOE is that it will start expensive, and perhaps remain so, compared to fossil fuels (ignoring environmental costs). Only gigawatt-scale AWES unit concepts really seem to promise super-cheap energy. In any case, we await historical judgement to settle debate between AWE economic pessimists and optimists.

    Several AWE ventures have identified attractive market niches for high-priced AWE, where energy costs are already high, like remote islands and military expeditions. Some poor populations, like the Solomon Islands, abide with the highest high energy costs. They do not lavishly space-heat with electricity, like some elite "Northern" markets do, but can get along with modest lighting, fans, and device charging. On bio-ethical grounds, years ago, I happily gave up my car and large house to buy a small urban forest, and live as much as possible on solar, wind, and human power. The extreme high-cost of unit-energy required to pedal my bike is an accepted cost. Almost anyone could make the lifestyle jump, if they tried.

    Its a gross fallacy to reason that expensive goods, as such, are not economically viable. Gold and diamonds are expensive in direct proportion to their economic viability. France's prosperity, in particular, is based on luxury pricing of its native products, so Pierre, especially, should understand high-priced economic viability. AWE may therefore begin to thrive as a green "luxury good", but still be affordable to the poor, as micropower, then hopefully become universally cheap and abundant. Most any public utility can adopt the Austin Model for quickly developing windpower. Its as simple as offering ethically-minded educated rate-payers an AWE option at the natural price-point.

    Given these obvious facts, no wonder AWE pessimists remain a small poorly-informed clique. They are far outnumbered by even just the PhD minority of AWE domain experts rebutting them. Even given initial high-price, the case for future AWE economic viability seems strong and growing.

    The price of solar PV cells has been steadily dropping for years . . . . and there is widespread use of subsidy-free micro-power solar generation in many developing nations, usually in remote areas where solar PV technology recharges batteries that operates LED lighting in homes and villages. Solar PV can also operate calculators and computers.

    Small scale AWE will definitely be able to generate small amounts of electric power to operate LED lights (street lighting), pump water to higher elevation and perhaps perform a variety of other tasks. Kites are also attractive to tow boats along trade routes, where ships sail parallel to the direction of the winds . .  . this in my view is where large-scale kite technology needs to develop.

    While electric generating equipment is costly, piston-type water pumps are relatively cheap by comparison . . .  there is a need to pump water in many nations . . . . and this is a possible niche for looping kite technology.

    I would urge AWE proponents to focus on what works at the present time . . . pursue and develop opportunities in those markets for AWE technology. 

    Perhaps we may be getting a little ahead of ourselves by trying to adapt AWE technology to grid-scale power generation . . . . there are many other very essential intermediate steps that will pave the way for AWE power generation.

    Harry,

    True, there are endless small apps for AWES optimists to tap. A favorite would be an AWES kit to charge an electric vehicle, perfect for remote operations without fuel, and the vehicle might serve as a mini plant for a needy village.

    Rapid utility-scale AWE is a stretch, as you point out, pending a lot more engineering due-diligence. At least two interesting workarounds exist: Legacy power plants could grow into kite hybrids from a modest beginning. Even a toy AWES can add to generation if allowed to impinge its force on the generator shafting. Full powering might follow by gradual addition of kite. Small producers, by net-metering and feed-in tariffs, can also create utility AWES "shadow plants" by force of numbers.

    Please take a close look at Sabic, the Saudi AWE investor, from your perspective as our Arab-World expert. Your opinions would carry extra weight with the Dutch fund managers. They have a only a narrow AWE play with KGR, and might be convinced to expand and diversify,

    I have to say you are so delusional to think existng power plants could or would try and incorporate input from a toy AWE system.  They are going to have large shafts rotating at grid speed, while you offer an intermittently-pulling, intermittent source of downtime and danger for the whole plant.  They are way more worried about preserving a good safety record than having you wrapped around their shaft with your parachute ("Jane stop this crazy thing!")  I think you might be mixing up your steam-punk costume-party fantasies with the real world of power plants.

    The way it's done is you generate power and put it into the grid.  No, nobody is going to let you stick your fingers in their 100 MegaWatt gas turbine/genset drivetrain.  "No, you can't use our generator (moron) - get your own!  You can use our grid - isn't that good enough for you?"

    Also, a few moments ago I flashed on how you keep quoting Fort Felker as though him saying to test things (obvious) rationalizes your lack of focus, which you refer to as "test everything".  First, I'd point out that while testing essential, it has to be part of a focused effort, lest the lack of focus mean the effort becomes the proverbial monkey-at-the-typewriter.
    Second, if Fort Felker of the NWTC had the answers for AWE, don't you think we'd see futuristic turbine designs coming from the NWTC?  What do you think their best futuristic design is?  Oh, there are none?  Think about it...
    At one time, I was impressed with all the multi-letter agencies and the big VC firms.  I thought if I could talk to them, together we'd change the face of wind energy!  That was until I spent time interacting with them a bit, whereupon I found the multi-letter agencies mostly a bunch of un-curious meeting-attending paper-pushers, and the VC firms surprisingly completely unable to grasp even the simplest facts.  I was really quite surprised and pretty appalled at the lack of interest in trying anything new from the multi-letters, while I found the VC's such as Kleiner Perkins unable to understand why, say, a FloDesign turbine was a bad idea, even if you directly explain, at great length, the exact reasons, right to the top CEO's and founders.  They just stare and blink like no matter how many ways you try and describe the reality, there's just no connection.  On the other hand I had people telling me years back how easy it was to get them to hand you millions of dollars just by merely filling out paperwork and making optimistic statements.

    Make a list of all the revolutionary wind energy concepts in use today that originated at any national lab.   Let's see, the first item is...
    Wait - maybe the list is empty!  I can't really think of anything major they've contributed.  Maybe they test some airfoils and help optimize existing systems a bit, eliciting papers on how much energy is lost due to fouling by bugs, and then recommend that people clean their blades.
    Basically they are getting paid to write papers on what everybody already knew anyway.  Keep that steady government paycheck coming in.  That is boring stuff that is not likely to bring something as radical as AWE into the forefront of technology.
    The bottom line is, the people we want to be our heroes turn out to be very boring toe-the-line type people whose personality types want a steady government job, rather than the adventurous personality types necessary to discover new things. Get stuck in their quicksand at your own peril.  I'm sure you've heard the saying "those who can't do, teach".  And those who are unlikely to try anything new are drawn to agencies responsible for trying new things, whereupon they immediately set up programs to make sure nothing new is ever tried or hopefully not even discussed.

    Lift boulders and drop it from a kite system to get smaller chunks. 
    Lift a skydiver and drop him or her for a neat ride for special purposes. 
    Lift a pre-made hut to a high point that has not adequate roads for such a move. 
    Lift treeling with spearing penetrator for planting a forest.
    Have seeds in arrows; drop them for penetration into soils. 
    Drop water where needed. 
    Drop food and supplies where needed. 
    Place personnel where needed. 
    Plant small cameras here and there.

    While the toy AWES contributing energy to a large power plant is a whimsical demo, its not as "delusional" as giant rotating towers "flying" (nor Columbus discovering an absence of archery in the New World).

    The future of kite hybrid power-plant is being discussed with top energy execs in Texas. They are professionally able to see the toy AWES experiment as a helpful and clever Gedanken. No one doubts that a urethane skate wheel turning by kite power from outside the plant can in fact contribute its bit of momentum to a large shaft. A demo would be largely symbolic, but still real.

    More realistic designs would be far larger and use a clutch. In Austin we are beginning by cutting apart small gas generators and adding clutching and flywheel mass to make kite hybrids. Of course this is tricky work for skilled engineers. We rely on our team backgrounds with long heavy-machinery and metal-fab experience to "keep us real",

There is definitely a non-empty interface that will be receiving some exploratory tests. The ring of what might become a slogan filled my breath on the matter this morning: 

    "Positive kiting helped by negative kiting; and negative kiting helped by positive kiting!" http://www.energykitesystems.net/Structures/AftToTether/index.html

    Yesterday at KiteLab Los Angeles, a teaching trial gave stark downing via use of positive kiting. 

    Then a trial of negative kiting to support positive kiting was accomplished by use of the AoWtMT structure. Very low mass was used. And scribbles on the bathroom mirror from 4 a.m. waking will be soon translated to some further explorations for even more super-low-mass AoWtMT-held negative kiting to support positive kiting.    Aim in part is to bring ways and means to holding HAWT as well as negative gyrokites that generate loop driving ro direct electrity, as well as other purposes.

    There has been a technical news blackout by Makani Power ever since the GoogleX buyout. Finally, a clue to the Forum-predicted Makani AWES scaling crisis has emerged. 

    A talented TUDelft student, Jelle Wijnj, under RolandS, has completed a preliminary aero-elastic study of the M600, both simulation and wind tunnel results. This is apparent contract-work let by GoogleX, complete with NDA restrictions.

    By accident, a confidential finding-version was briefly posted on the Net; that the known over-optimistic M600 design would require a 50% increase in structural strength to meet its max-loading margins, which means a lot more flight weight, with a corresponding desperate need to fly faster, with less slow-flight margins; as a losing aerospace end-game. 

    I was asked by TUDelft, via a third party, to keep the NDA-protected lapse a secret, but I am not under any NDA, and oppose AWE NDAs, on ethical grounds. TUDelft only seems to increasingly embrace such secrecy, as noted regarding the Saraceno Solar Bell project's curious failure to seriously address human factors in kite Aerotecture. Roland is also dragging his feet in responding intellectually to data reanalysis of TUD kite studies with regard to megascale arches (static stability and dynamic oscillation modes).

    A proper, nicely dynamic, figured out cradle; bows, gives, guides, embraces and hugs it's charge.

    If GOOGxKANI want to pay me a heap to sketch one.
    I'm all for that.
    I'll spend the money on my own idea designs of course but someone aught to.

    The weight of the tethered wing also generates stresses during crosswind operations. So now there are two directions (aerostats and turbine on static kite being good but not enough): rotation (with some very recent bad or good variant of helicopter-mode I shall tell; note the analysis of http://wheelwind.com is not still sufficient to build it) or oscillation.

     

    DaveS: please can you provide the modus operanti of Arch (both oscillation and airborned system), at least when you will provide a complete description to Dr.Roland Schmehl for a detailed study; and also please build it with the generators.I call it "Jupiter's shiver" (with a little of mockery, but not completely). Then post against DougS. 

     

    DougS: please build your latticework Super Turbine(R) (both rotation and ground-airborned system) I call "Leaning Tower of Pisa" (without mockery or almost). Then post against DaveS.

    Doug,

    AWE is both windpower and aviation-aerospace (Energy Aviation), one cannot neglect either field and hope to succeed. Kites are a key technical specialty.

    Many of us truly embody the full AWE interdisciplinary requirement. Dave Lang, Chris Carlin, the Roeselers, Jalbert, the Wrights, JoeF, Wubbo, and so on. At least concede, that as a group, the aviation-oriented intelligence in AWE sums far beyond yours. 

    Human aviation is exquisitely energy-smart, as errors easily end in death. Backyard turbine "pilots" must have no idea how much more demanding aviation is, if they think like you. The last we were informed on your aviation experience, even your radio-control model escapes you.

    Our conventional windpower experts, like Coy Harris and Fort Felker, are first-rate, and true fans of pioneering AWE R&D. You and Gipe do not match them in reputation, knowledge, or accomplishment. Expect to be caught flat-footed by superior intelligence,

    daveS

    OK go down, on record, as declaring "kites are a key technical specialty" for AWE.
    So if useful systems emerge without using kites, you will be proven an idiot without vision, stuck in a rut of outmoded thinking - a luddite.

    (No you will redefine whatever emerges as "a kite" so as to pretend you won another argument you really lost, by redefining words - yes we know, your game of substituting erroneous word definitions for progress is exposed.)

    "Expect to be caught flat-footed by superior intelligence"
    Sure Dave, like whom, you?
    I at least realize I am pretty dumb, and it is easy for me to see most of the rest are way dumber than that.  At least I realize I am dumb.  You think you're so enormously smart, while demonstrating daily how dumb you are.

    All anyone has to do is go back and look at what you wrote at any time in the past and hold it up to the light of day to see almost every statement you publicly make is just plain wrong, like claiming the Honeywell rooftop turbine was a great device even after one of your heroes Coy Harris explained to you how it was not even working.  It's ongoing,  Your constantly-evolving state of ignorance remains, nonetheless, squarely mired in that ignorance.  All you have left is to keep bragging and threatening.  To summarize, Duh.  There, I have explained it in your own language.

    Subject: Why and how Bol - like and spinning
    Attachments :
      Time for some purposeful practice

      A recent critique of bol kites is that they are hard to launch as they scale up.

      Explore the varied reasons for this.

      The top edge has to be lifted higher than a human can lift,
      Spinning Bol's want to be moving too... it's not the top edge any more.
      If the bottom is already driving the un-inflated upper gets dragged round sideways instead of inflating upward.
      Before the upper foil can fill and be held by side wall foils it's blown backward.

      Your other explanations are most welcome.

      What we really seek from a bol is something that initially behaves more reliably in inflation... Like a parachute, drag chute ... and transitions after inflation to a powerful rotor device.

      So which mixes of tech get us where we want to be ?

      A reliable opening non rotating chute at most downwind point.
      staged launching starting with smaller drag chutes initiating larger openings.
      A semi-rigidised leading edge to encourage the kind of outward pop opening witnessed in the flysurfer peak videos.
      fractal level based / or  bi - -tri- furcating / or ring catenary front bridling to spread the sheet without resisting spin.
      Well folded packing.
      An over tensed collapse mode shape, where outer winglets and driver kites are both faced with positive inflation AoA (means an inner line)

      Trying to get there with this...
      Inline images 1
      this type of design was recently criticised for having too little active driving surface
      makes a change from my usual over solid.

      I'll want to change the above so that the front bridling more matches the winglets encouraging initial inflation.... Does the trailing rope tension to the inner lead or kites or trailing rope or necessarily anywhere, (probably the driving kites but I don't want it to get too complex so as to be un-serviceable)

      advice sought as ever
