Wow, Joe, what a bumper crop of new references. Nobody seems to have predicted AWE would develop such intense academic interest so fast. The trend can only continue. Progress in AWE is surging on greatly increased physical testing and formal analysis. A critical-mass of domain knowledge continues to build. While much early AWE research is naturally repetitive or off-target, there is plenty of true gold to mine in the growing mountain of work.

Subject: Re: Distinguishing CF in AWE v Conventional Wind (review)
And so after a decade of your intensive research, what is your highest power-to-weight answer?
Can we see the output please?
By the way, your detailed characterization, below, is mostly just stuff you've made up, in your continued fantasy of how everything "will work".  Amazing how readily certain people describe in such great detail how things "will work" (in the future) but just can't make anything work, at all, today.
The quote below: "We have long identified here many other critical differences between upper and surface wind engineering" sounds so knowledgeable, but seems to just be an ongoing charade to feign ongoing "expert" status, without sufficient "expertise" to complete the task of generating a significant amount of electricity.

---In AirborneWindEnergy@yahoogroups.com, <santos137@...  

As noted on the KiteGen CF usage topic, AWE CF depends uniquely on factors related to aviation and the greater constancy of wind with altitude. Conventional wind design is not aviation design capable of reaching superior upper wind. A quick review of past CF discussion-

Aviation reliability requires constant inspection and maintenance, which reduces CF compared to industrial surface equipment. Storm avoidance for an AWES requires conservative retraction, while conventional turbines operate right up to storm squalls, feather, then recover fast, compared to aircraft that must land and take off. When winds go light, the highest flying AWES is last in the sky and the lightest AWES is first to launch when wind returns. The CF availability of upper winds are superior to conventional surface wind, offsetting and maybe beating aviation CF losses.

We have long identified here many other critical differences between upper and surface wind engineering, each necessarily optimized to harvest two very different wind resources, with very different methods demanded for a turbine-on-a-pole v. power kites.

You wrote: We'll wait for someone to find your "I.P." relevant in any way.

Thanks for finally agreeing to wait for actual AWE outcomes, now that your general pessimism is so well established. 

Hardly any AWE IP counts, since practical kite methods are mostly open-source. I don't recommend patents as worthwhile IP, except for an eventual Patent Pool like aviation history. We'll see what sticks of the countless public ideas in play.

Subject: kPower's Criteria for Expertise in AWE
There really are AWE Experts, and this is the "right stuff"-


- Follow ongoing AWE research papers, videos, and forums.

- Know aeronautical principles, history, and engineering.

- Know conventional wind principles, history, and engineering.

- Know power kite technology as a COTS baseline model.

- Participate directly in varied testing of AWES prototypes.


Gain just three of these virtues be a true early AWE expert. By this criteria, quite a few fine friends qualify.

The simple question, which you are trying to avoid, is how much electric power have you generated, and what is the weight, after ten years of your stated AWE "research"?  Your stated 1 kW/kg sounds great.

I'm not interested in generic statements of how much power a kite is theoretically exposed to.  Yes a kite "can pull".  That much I knew in Indian Guides as a second-grader when we (mostly our dads) learned to make some pretty cool kites.  "Kites can pull".  Remember that folks.  Now what?  Kite-reeling again?  I think I thought of that by age 8, a "breakthrough thought" that just about anyone reeling a kite has experienced..
The challenge in AWE has never been whether the power is available, or whether the technology exists to fly a kite, or whether a powered reel can theoretically extract some intermittent power..  The challenge is to use the wind's energy to generate electricity in an economically-superior way.  The entire charade you've watched for the least decade is that everyone can see the power is there, but the skills required to extract it go far beyond the ability to fly a kite. Still, most "teams" are stuck at kite-flying, really, still mostly just trying to master flying a kite at all. let alone making much, if any power, and let alone doing it cheaper than existing wind turbines.

Thanks. Power kites are wonderful. KiteGen topped 100kW in surges over a decade ago. Creating and mastering power kites has long been community effort, and not everyone can be the peak-power leader.

Subject: COTS Dual Clutches for Kite<->Fuel Hybrid Engines
To roll your own kite-fuel hybrid engine AWES suggests some sort of double clutching to mix and transition power sources. Variations include over-running clutching and torsional shock absorbing clutching. Here is a sample COTS double clutch product at automotive scale, not a specific recommendation. Our standard option has been to manually adapt generator shafting with two individual clutches, but lets keep a lookout for ideal double clutches for prototype AWES hybrids, including for two independent kite inputs. Our holy grail is many clutches along one shaft.

Doug, you seem unaware my work focus in experimental kite power is on the mechanical side, including feats like Mothra dumping tons of sand, kite-sailing, and many other apps, not just electrical power. We are both far behind peak electrical power demos by others. I do not claim to be tops in peak electrical power, but if you know anyone with more varied experience in AWE, lets give them due credit. BTW, KiteSat can show high CF by flying very high with a good pilot-lifter, insofar as max CF counts. You must depend on helium for comparable high CF with an ST.

Who do you think tops in AWE? 1000 folks can't all be idiots like you seem to imagine.

Subject: Re: Lineshafts to groundgens
Clarifying that an AWE work-cell aggregating lineshaft based on historical antecedents would be located at the groundgen, rather than airborne. Rope drives from surrounding kite fields would converge on the lineshaft, each with a clutch. Similarly, multiple generators and motors could share the lineshaft. A massive surface-mounted lineshaft would be only as long as required to crowd on inputs, rather than a lightweight shaft able to reach upper wind.

The carousel AWES concept also seems suited to drive GW scale gens using practical kites*, at far higher mass and capital-cost The LadderMill is another contender, with huge return-side and surface-phase losses, and kite-passing complications

Subject: Autorotation low radius loop

Today I remade the experiment of autorotation with only one other wing then I obtained the same result as on the following video I put again: https://www.youtube.com/watch?v=0GflQyDDQec.


4-5 kg regular traction measured with a steelyard on the line taut with 4 m/s wind speed while I obtained 3 kg surge traction in crosswind larger figure-eight and for one of the two lines, the other line giving a lower value in the same time, and the total value being irregular and probably lesser.


So it looks like an autorotation with low radius loop could generate more power by using less space than crosswind large figure-eight that are generally envisaged.

Subject: Re: Autorotation low radius loop
Yes, soft-kite autorotation is a proper design class sharing partial properties with rigid-bladed versions. Fast turn rate works well to maximize airspace, and its a proven advantage in wild free-style kite sports with LEI C-kites. With longer lines and straighter motions, like foil-boarding, the parafoil race-wings are flatter, have higher L/D, but do not turn so fast. Both kinds of motion are useful according to specific needs.

There is a sweet zone between too fast and too slow a turn rate for each kite design. Helical-pitch wing tuning is a refinement naturally done with four-line kites, and can be done passively two-line by small modifications. No one yet seems to have bothered sewing an asymmetric kite for optimal turning in one direction, but such wings will emerge, as predicted by the applicable optimality principle.

Note that power extraction is reduced at the main anchor, by a cosine loss effect*. In Pierre's case the power comes from a "jump-rope wave" created by the kite. Extracting power in the kite's crosswind plane is far more effective, but requires extra anchors and rigging downwind. Maybe a small ballast mass on the line at the kite can enhance the jump-rope wave to the single-anchor rig. 

A pilot-kite also seems worthwhile, for extra session stability and extra lift actually adding power by canceling the looping-wing self-lift load, and the added tension transmits pumping more efficiently.

-----------
* Cosine loss effect was first noted for kite high flying angle by TUD, but occurs commonly in many rigging situations when "rigger's force triangle" expresses adversely.

Subject: Cosine Loss and DePower note
In a kite model that properly includes gravity, cosine loss at zenith happens to correspond to maximum potential energy of mass at height.

If an AWES wing is over-powered in high wind, one solution is to seek zenith and do depowered pumping up there, to match load and respect working load limit.

Subject: Should Power Kites ever have added Ballast Mass?
Based on performance glider similarity, the answer seems to be, Maybe Yes, even if unballasted states predominate. Especially the Ampyx's hot kiteplane hopes to replicate performance glider best practice, and speed, ballast, and high L/D go together.

Power Kites are very sensitive to their inherent mass, using it to do DS boost within Dutch-Roll/Figure-8 and looping cycles, with smoothed sine-wave pumping outputs. A massless kite would be kicked but floaty.

We knew kite (or airplane) Dutch-Roll to be the beginning of a Figure-8 (or Lazy-8), and that somehow power kite Figure-8s feel right, and want to fly themselves. Its a mirror-symmetric figure that does not wind up kite lines. 8 output is a nice sine-wave pumping. As the kite flies each half of the pattern, a pendulum-like trading of potential and kinetic energy occurs. The wind continues to add energy to harvest as a damping factor.

To fly a power kite passive-8, simply stake out left and right lines to set oscillation amplitude and stability factor. Line-length and wind velocity determine frequency. DS boost-effect occurs when the kite is at the edge of the 8, moving downwind in the KW, in lower relative wind; then turns into higher relative wind as it crosses the power zone. There is hope for kite-network designs of many wings pumping in passive synchronous-8s.

Here is a mathematical link to basic lemniscate  (figure-8) formulas. A suitably rigged kite nominally embodies calculation of its lemniscape flight path. Compare with active digital computation with sensing and actuation.

To confirm passive-8 pumping for yourself, in a smooth breeze, fly a small short-lined two-line power kite with arms stiff and spread apart. The kite will spontaneously Dutch Roll or fly 8s according to how wide you spread your arms.

Adding a Payne fig5 drive loop crosswind at the kite, as described recently, can actually eliminate the chance of looping, for very robust passive-8 pumping.

Subject: Re: Should Power Kites ever have added Ballast Mass?
Here's paragliding also ballasting according to conditions. Ballast can counter dangerous cloud-suck, smooth ride, add speed, etc. when high lift conditions warrant, but in low lift conditions, weight becomes toxic. Low altitude hobby kites must especially tolerate relatively low velocity conditions, so lowest weight is design gospel. Flying high under new superior wings changes the picture dramatically, that (only) in strong gliding or kiting conditions one can carry a lot of extra payload and actually fly better (!)

Our AWES flying formations will be sensitive to all sorts of terrain/wind-field vertical convective features, including long distance mountain wakes, variable surface insolation, cloud interactions, and so on. So far, AWES models neglect these effects, using only simple statistical randomness to model general flight robustness. However, many common wind formations are coherent chaos, like weather fronts and microbursts. Real weather is a zoo of agent-like effects, not just the buffeting of random noise. This FAA soaring guide covers a lot of the vertical air wildlife AWES will soon face.

*** DougS replies: The point many don't appreciate, especially you, is that there have always been outsiders advocating "alternative" wind energy collection system designs and concepts.  99.99% of the time they are wrong.  Ten years ago I used to ask the question from bathroom graffiti: "Can a million flies be wrong"?  The answer of course is yes, a thousand people can be wrong and so can a million people.  The term "idiots" is often applied by real wind people when the newly-hatched wannabes seem particularly clueless, annoying, or even just if they are pursuing known dead-ends. 

The way I have always seen it, AWE is a great pursuit, but I didn't see anyone about to master it ten years ago and still don't.  The problem most of the would-be, wannabe, wind energy innovators have is they want to substitute "feelings" for energy produced, and they want to substitute "saying" they will produce power for actually producing it.  You gave an answer I hadn't heard yet,

"Doug, you seem unaware my work focus in experimental kite power is on the mechanical side, including feats like Mothra dumping tons of sand, kite-sailing, and many other apps, not just electrical power"

but it falls smack-dab in the middle of such rationalizations and excuses for no power or low power in proportion to size, cost, complexity, and reliability.  How many times do we need to her about the accidental lifting and shedding of some sand?  Ten years of "research" for that?  Figure out a way to generate some power!  I have some ways in mind for you if you can't think of any.
 
And when real wind people point out that the would-be-innovators don't have a better way to generate power from the wind, the would-be-innovators typically get angry and call the real wind people names.  They think that saying they will produce power at some future point in time, on the internet, is a substitute for producing a machine that reliably produces electricity at low cost.  But reliably producing electricity at low cost is the only thing that matters.  Not group-selfies.  Not claims of "bird-friendly".  Not press-releases announcing upcoming grid-feeds that never happen.  Power.  That is the goal, and if you can't show a way to do it better, you're missing the mark.
  Now someone who knows nothing of wind energy might find it extreme to hear us use a term like "idiot".  But it's not so farfetched at all, really.  When we get together it's the term often used for, well, you know, vertical-axis people, and, well... anyone who insists their half-baked ideaa can outperform the best wind turbines in the world, for example.  Anyone can say it.  How many are right?   Let's start with asking if there might just one single "idiot" out of the thousands of candidates you cite. 

Take Magenn, for example.  Now you don't need a college degree to know Magenn was a very expensive way to place a less-effective version of the least-efficient known type of wind turbine, with a paltry amount of swept area, into the air.  There was never any indication that it formed any sort of reasonable wind energy solution.  It generated almost no power compared to its size and cost.  It was easily disproven on a napkin using a crayon.  I immediately said only an idiot could believe in Magenn.  I believe that is a true statement.  If there is such a thing as an idiot, someone falling for Magenn would have qualify.  Especially if they had a college degree - in, say engineering.  Yet didn't the Magenn Sta-Puf marshmallow-man grace the covers of hundreds of magazines and websites?  Didn't Magenn hire engineers?  Didn't even NASA and the big AWE "industry" organizations use the Magenn image in promotions?  OK how many "idiots" are we up to now?

Let's take Altaeros.  You, daveS, noted that the envelope would use less material to hold more helium without the donut-hole.  It was not so hard for anyone to see, but you had previous LTA experience so you knew.  You knew it was a bad design.  You were in a position to say "these guys must be idiots" had you chosen those words.  With some experience in wind energy, knowing how brutal the wind is, seeing the frail donut envelope, I too was able to not only make the same observation as daveS, with regard to the envelope, but also to see that it would be unlikely to survive strong winds.  I mean, seriously, real wind energy will just rip your shit apart.  Not for the timid or faint of heart.  So, to us, for a highly-educated engineer to not be able to see what we could see, in our view, we might be forgiven for saying anyone who can't see what we see is "an idiot, even if they are a trained engineer?  Especially if they are a trained engineer!

Look at Kleiner Perkins - chasing another disproven ducted turbine design.  Many people tried to warn them,
including me, but they invested millions, found out it totally sucked, as everyone does, then sold Ogin for 50 million to New Zealand, who had already wasted 20 million on a previous ducted turbine debacle called Vortec.  Was New Zealand on a sucker's list?  I think it was me who spilled the beans to KP - sorry NZ I didn't mean to!   I was trying to get KP to give it up!  I only used you as an example of how dumb it was! 

Are you going to tell me hundreds of real wind energy people did not tell all these people right to their faces they were "idiots"?  Well I know I did.  We were trying to save them from their stupidity.  Trying to save them wasting millions of dollars.  To us, yes, there were all idiots!  How much more idiotic do you want someone to be before you come out and say it?

So, whether you see 1000 geniuses, or 1000 idiots, depends on your point of view.  Only the future can tell us, in many cases, right?  But people with more wind energy experience might know better than the newbies think.  After all, they have to design, build, install, and run, machines that can do the job, and fix them when they break.  So their perspective is from the school of hard knocks.  Maybe we're looking at 999 idiots and one genius.  Maybe it's 997 and 3.  Maybe it's all 1000 and zero.  Maybe it's a few hundred either way.  Half-and-half? Way too optimistic, sorry.  Whatever the case, when you start adding in the magazines, the website people, the pundits, the investors, the lawyers, the entrepreneurs, besides all the teachers, students, interns, employees, secretaries, human resources people (groan), office managers, (ahem) "engineers" (choo choo!) I mean, it's out-of-control, right?  Kind of like Bitcoin, Flexseal, or 3-D printing?  Maybe one team is on the right track, and the rest are lemmings running for various cliffs.  How about that?   I'm thinking we're way over 1000 - of something.

The challenge in AWE has never been whether the power is available, or whether the technology exists to fly a kite, or whether a powered reel can theoretically extract some intermittent power..  The challenge is to use the wind's energy to generate electricity in an economically-superior way.  The entire charade you've watched for the least decade is that everyone can see the power is there, but the skills required to extract it go far beyond the ability to fly a kite. Still, most "teams" are stuck at kite-flying, really, still mostly just trying to master flying a kite at all. let alone making much, if any power, and let alone doing it cheaper than existing wind turbines.

Realizing utility-scale AWE can be far more difficult than current ground-based turbines, at least to find the adequate solution, perhaps less after. Numerous fields are involved, including wind energy production, aerospatial, a part of artificial intelligence and so on.


If AWES was easy it would be enough to take any wind turbine and hang it to a kite.

AWES face to three major difficulties: to fly, to produce energy, and to make them both.

    Subject: Dynamic Anchor-Field Tech (DAFT)
    Most AWES schemes presume a fixed single-anchor kite-cell kitefarm design. The historical record supports multi-anchor designs for key capabilities, like Baden-Powell's extra safe arch-rigged man-lifting system and Payne's patent fig-5. kPower is the one AWE venture that has tested and developed multi-anchor AWES concepts. The EU reeling circle can confidently re-rig their anchor-winch groundgens in pairs crosswind, after Payne, Goldstein, and Open-AWE_IP-Cloud technology, once they tire of high cycle losses of reeling downwind and hauling back upwind. Looking forward, Kite Networks will depend on complex anchor-fields. This a huge design space that roughly divides into fixed iso-lattices and dynamic anchoring.

    Kite vehicles are dynamic anchors, and we must keep in mind that massive mobile anchor "buggies" could prevail in many cases. An even simpler dynamic anchor basis is to belay kite tension from fixed anchor to fixed anchor. However, this basic method, upon which industry still relies in blue-collar towing and crane-work, is not part of the sociology of white-collar professional-classes, like most PhDs and engineers in AWE R&D. The idea of a blue-collar kite farm rigger moving anchor points semi-manually is simply absent in AWE R&D social-elite circles, whose preferred worker is supposed to work indoors, in composite-airframe and avionic production.

    kPower's prediction is that Dynamic Anchor-Field Tech (DAFT) is going to work great. New polymer ropes, rope-chains, and webbing allow a single worker to handle powerful tensile loads that not long ago required a gang. Handling equipment has progressed so that a field worker's productivity is vastly magnified. Disconnecting-reconnecting operations at ~3MW worker-to-unit-power can be done in under a minute. Instead of an iso kite network that is always far deeper than ideal along the wind axis, a planar crosswind AWES can be rotated without fuss at a huge scale, far faster than common changes in wind direction due to prevailing weather patterns.

    DAFT will preform many essential AWES functions besides basic reorienting, like reconfiguring kites and lines according to wind velocity or load demand, and killing the network when needed. Fully automated DAFT will gradually emerge. The future of AWE will likely be strongly DAFT.

    Most AWES schemes presume a fixed single-anchor kite-cell kitefarm design. The historical record supports multi-anchor designs for key capabilities, like Baden-Powell's extra safe arch-rigged man-lifting system and Payne's patent fig-5. kPower is the one AWE venture that has tested and developed multi-anchor AWES concepts. The EU reeling circle can confidently re-rig their anchor-winch groundgens in pairs crosswind, after Payne, Goldstein, and Open-AWE_IP-Cloud technology, once they tire of high cycle losses of reeling downwind and hauling back upwind. Looking forward, Kite Networks will depend on complex anchor-fields. This a huge design space that roughly divides into fixed iso-lattices and dynamic anchoring.

    Kite vehicles are dynamic anchors, and we must keep in mind that massive mobile anchor "buggies" could prevail in many cases. An even simpler dynamic anchor basis is to belay kite tension from fixed anchor to fixed anchor. However, this basic method, upon which industry still relies in blue-collar towing and crane-work, is not part of the sociology of white-collar professional-classes, like most PhDs and engineers in AWE R&D. The idea of a blue-collar kite farm rigger moving anchor points semi-manually is simply absent in AWE R&D social-elite circles, whose preferred worker is supposed to work indoors, in composite-airframe and avionic production.

    kPower's prediction is that Dynamic Anchor-Field Tech (DAFT) is going to work great. New polymer ropes, rope-chains, and webbing allow a single worker to handle powerful tensile loads that not long ago required a gang. Handling equipment has progressed so that a field worker's productivity is vastly magnified. Disconnecting-reconnecting operations at ~3MW worker-to-unit-power can be done in under a minute. Instead of an iso kite network that is always far deeper than ideal along the wind axis, a planar crosswind AWES can be rotated without fuss at a huge scale, far faster than common changes in wind direction due to prevailing weather patterns.

    DAFT will preform many essential AWES functions besides basic reorienting, like reconfiguring kites and lines according to wind velocity or load demand, and killing the network when needed. Fully automated DAFT will gradually emerge. The future of AWE will likely be strongly DAFT.

    Confirming that short-radius paths are crucial to airspace conservation and kite-network unit-kite function. Giant AWES sweep patterns, where the power-kite looks tiny in its pattern, is a relatively obsolete developmental phase of our epic optimal-design quest.

    Thanks to PierreB for his sharp observation. The latest dancing kPower rigs also fly compact patterns, which are more stable for passive dynamics. Short-line proportions of very large kites (to fit FAA 2000ft ceiling) is also a key part of improved AWES geometry.




     

    These relevant observations deserve deeper analyses. A pilot-kite looks to be difficult to implement with only one wing, excepted by adding some rigging. I plan to do the things as simple as possible.

      Here we see confirmation that classic fiber-drives shed harmful particles, largely due to friction around spools and pulleys. This suggests that jerk-line rope-pumping is favored, since pumped rope need not be wrung around a wheel. A short gypsy-winch chain/sprocket section can take pumping motion at the winch, without excessive particulate pollution.

      Subject: Re: Distinguishing CF in AWE v Conventional Wind (review)
      daveS,let's review the three horsemen of AWE: Makani, Altaeros, and Magenn.  These three were the most popularized as examples of AWE.  From a wind energy standpoint, I think my previous explanation sufficed to establish that anyone promoting Magenn hd  to have been either dishonest or clueless.  That included all the publications that  repeated  the false narrative that it was even effective, let alone a breakthrough.  If you include everyone who promoted the Magenn debacle, how many "idiots" or "know-nothings" or "people who are wrong, saying they are right" are you up to at that point?  Hundreds?  A thousand?  How many publications and websites repeated the "news" that Magenn was going to be powering our future?  Were ANY of them right? - no, they were ALL wrong.
       
      OK let;s take Altaeros next.  DaveS did a great job of debunking it based on his LTA knowledge.  So daveS proved that it was a bad design, on paper, and his points were easy to see, and really could not be argued with.  So, again, one could use whatever words work for you to describe it: People being wrong but saying they were right", "know-nothings" - for shorthand, you would imagine that real wind people sitting around having a private conversation using the term "idiots" because they really know what it takes to do wind energy, and they have nobody censoring their words in a private conversation.  You could take it further and validate which statements they've made over the years, see how many of them have come true, including more recently Oman, Mitsubishi,then Wifi, and, from what we've seen so far, verify that pretty much most of what they've promised, or predicted, has fallen flat, and not happened.  So now, take all the people who repeated the Altaeros hype, published their pictures and repeated their promises.  That alone has got to run into the thousands of people.  So now we've debunled two out of three of the most visuible and talked-about AWE efforts.

      Next let's examine the "third horseman of AWE" (as popularized) which is Makani.  Once again, daveS has debunked their effort more thoroughly than anyone else I can think of.  Their mistakes, according to daaveS include making a too-early "diownselect", making the wrong "downselect", not taking into account the realities of wind energy, building a crash-prone machine, not followinig through on their stted projects to power the grid in Hawaii, etc., etc., etc., 

      Now let's assume daveS is right about Makani.  That's all three of the main poster-child star players in AWE, all easily debunked by even the notoriously optimistic and forgiving daveS.  So, even compared to daveS, the 3 main stars of AWE qualify for "idiot" status, or if one wanted to be more charitable in terminology, they could be called"wind energy know-nothings", "people who are wrong saying they are right" - whatever terminology makes you comfortable. 

      So, we've (mostly daveS himself) now debunked the three "leading" AWE efforts, the ones that have made AWE famous.  Well if nothing all these people said for all these years was valid, call them what you want.  The fact is, you can now see that wnat I said the whole time "You are looking at "the bloopers"". was accurate the whole time.  Depending on your level of knowledge and experience, you can debunk things that others can't.  In this case, even daveS himsefl has plaayed  major role in debunking the three poster-child go-nowhere, know-nothing efforts in AWE, so, thanks daveS for helping to prove my point while simultaneously pretending to deny my point.

      We could go on to note that none of the kite-reeling efforts seem to be bearing any fruit - there is something wrong when, after all these years of hearing the promises, there is still nothing running in the kite-reeling camp.  And we could go on citing the hype over "laddermill" to note that nobody ever bothered to even try to build a single one, instead coming up with excuses of why it was too hard and instead they just wanted to buy and fly kites and play "kite-reeling" games with statements of grid-feed projects that never happened.

      These are all just the facts, daveS.  It was easy to just lie on the old days when everything was "in the future".  Well, people still want to play that game of false statements describing nonexistent future actions.
      What would you call someone who believes the next "story" of "promises of future grid-feed projects"?  Would you blame someone for using the term "idiot" after ten years or more of such empty promises?
      So, daveS, thanks for helping to debunk AWE as currently promoted.  You've done a great job.  Far better than me alone trying to explain that, as dramatic as the promises sound, these people don't know what they're doing.  Now that ten years have passed, we're no longer in a position of not having any way to prove it.  Now the people have proven it themselves.  Thanks for helping to get to the bottom of that one, and finally establish the facts of the matter, daveS.  Nice job debunking them, daveS.  It's really not that hard, now is it?  And by the way, I do call myself an idiot, every time I do something idiotic.  I think it;s healthy to be honest with yourself.  The first step is acknowledging when you're an idiot, so you don't make the same mistake again.

      ---In AirborneWindEnergy@yahoogroups.com, <santos137@...  

      daveS asked: "Who do you think tops in AWE? 1000 folks can't all be idiots like you seem to imagine."

      *** DougS replies: The point many don't appreciate, especially you, is that there have always been outsiders advocating "alternative" wind energy collection system designs and concepts.  99.99% of the time they are wrong.  Ten years ago I used to ask the question from bathroom graffiti: "Can a million flies be wrong"?  The answer of course is yes, a thousand people can be wrong and so can a million people.  The term "idiots" is often applied by real wind people when the newly-hatched wannabes seem particularly clueless, annoying, or even just if they are pursuing known dead-ends. 

      The way I have always seen it, AWE is a great pursuit, but I didn't see anyone about to master it ten years ago and still don't.  The problem most of the would-be, wannabe, wind energy innovators have is they want to substitute "feelings" for energy produced, and they want to substitute "saying" they will produce power for actually producing it.  You gave an answer I hadn't heard yet,

      "Doug, you seem unaware my work focus in experimental kite power is on the mechanical side, including feats like Mothra dumping tons of sand, kite-sailing, and many other apps, not just electrical power"

      but it falls smack-dab in the middle of such rationalizations and excuses for no power or low power in proportion to size, cost, complexity, and reliability.  How many times do we need to her about the accidental lifting and shedding of some sand?  Ten years of "research" for that?  Figure out a way to generate some power!  I have some ways in mind for you if you can't think of any.
       
      And when real wind people point out that the would-be-innovators don't have a better way to generate power from the wind, the would-be-innovators typically get angry and call the real wind people names.  They think that saying they will produce power at some future point in time, on the internet, is a substitute for producing a machine that reliably produces electricity at low cost.  But reliably producing electricity at low cost is the only thing that matters.  Not group-selfies.  Not claims of "bird-friendly".  Not press-releases announcing upcoming grid-feeds that never happen.  Power.  That is the goal, and if you can't show a way to do it better, you're missing the mark.
        Now someone who knows nothing of wind energy might find it extreme to hear us use a term like "idiot".  But it's not so farfetched at all, really.  When we get together it's the term often used for, well, you know, vertical-axis people, and, well... anyone who insists their half-baked ideaa can outperform the best wind turbines in the world, for example.  Anyone can say it.  How many are right?   Let's start with asking if there might just one single "idiot" out of the thousands of candidates you cite. 

      Take Magenn, for example.  Now you don't need a college degree to know Magenn was a very expensive way to place a less-effective version of the least-efficient known type of wind turbine, with a paltry amount of swept area, into the air.  There was never any indication that it formed any sort of reasonable wind energy solution.  It generated almost no power compared to its size and cost.  It was easily disproven on a napkin using a crayon.  I immediately said only an idiot could believe in Magenn.  I believe that is a true statement.  If there is such a thing as an idiot, someone falling for Magenn would have qualify.  Especially if they had a college degree - in, say engineering.  Yet didn't the Magenn Sta-Puf marshmallow-man grace the covers of hundreds of magazines and websites?  Didn't Magenn hire engineers?  Didn't even NASA and the big AWE "industry" organizations use the Magenn image in promotions?  OK how many "idiots" are we up to now?

      Let's take Altaeros.  You, daveS, noted that the envelope would use less material to hold more helium without the donut-hole.  It was not so hard for anyone to see, but you had previous LTA experience so you knew.  You knew it was a bad design.  You were in a position to say "these guys must be idiots" had you chosen those words.  With some experience in wind energy, knowing how brutal the wind is, seeing the frail donut envelope, I too was able to not only make the same observation as daveS, with regard to the envelope, but also to see that it would be unlikely to survive strong winds.  I mean, seriously, real wind energy will just rip your shit apart.  Not for the timid or faint of heart.  So, to us, for a highly-educated engineer to not be able to see what we could see, in our view, we might be forgiven for saying anyone who can't see what we see is "an idiot, even if they are a trained engineer?  Especially if they are a trained engineer!

      Look at Kleiner Perkins - chasing another disproven ducted turbine design.  Many people tried to warn them,
      including me, but they invested millions, found out it totally sucked, as everyone does, then sold Ogin for 50 million to New Zealand, who had already wasted 20 million on a previous ducted turbine debacle called Vortec.  Was New Zealand on a sucker's list?  I think it was me who spilled the beans to KP - sorry NZ I didn't mean to!   I was trying to get KP to give it up!  I only used you as an example of how dumb it was! 

      Are you going to tell me hundreds of real wind energy people did not tell all these people right to their faces they were "idiots"?  Well I know I did.  We were trying to save them from their stupidity.  Trying to save them wasting millions of dollars.  To us, yes, there were all idiots!  How much more idiotic do you want someone to be before you come out and say it?

      So, whether you see 1000 geniuses, or 1000 idiots, depends on your point of view.  Only the future can tell us, in many cases, right?  But people with more wind energy experience might know better than the newbies think.  After all, they have to design, build, install, and run, machines that can do the job, and fix them when they break.  So their perspective is from the school of hard knocks.  Maybe we're looking at 999 idiots and one genius.  Maybe it's 997 and 3.  Maybe it's all 1000 and zero.  Maybe it's a few hundred either way.  Half-and-half? Way too optimistic, sorry.  Whatever the case, when you start adding in the magazines, the website people, the pundits, the investors, the lawyers, the entrepreneurs, besides all the teachers, students, interns, employees, secretaries, human resources people (groan), office managers, (ahem) "engineers" (choo choo!) I mean, it's out-of-control, right?  Kind of like Bitcoin, Flexseal, or 3-D printing?  Maybe one team is on the right track, and the rest are lemmings running for various cliffs.  How about that?   I'm thinking we're way over 1000 - of something.

      As usual, you are dodging the question.  How much power have you generated?  Not Kitegen, you.
      Nobody is asking you to hold the world's record.  Just asking what your results are with regard to power generation, in the art of power generation, which you claim to have been a top researcher and expert in, for the last 10 or 12 years or so by this point.  Your answer is 5 Watts?  So no progress since 2009?  Why?  You claim to have been conducting AWE research all that time.  At what weight did you generate 5 Watts?


      ---In AirborneWindEnergy@yahoogroups.com, <santos137@...  

      The simple question, which you are trying to avoid, is how much electric power have you generated, and what is the weight, after ten years of your stated AWE "research"?  Your stated 1 kW/kg sounds great.

      I'm not interested in generic statements of how much power a kite is theoretically exposed to.  Yes a kite "can pull".  That much I knew in Indian Guides as a second-grader when we (mostly our dads) learned to make some pretty cool kites.  "Kites can pull".  Remember that folks.  Now what?  Kite-reeling again?  I think I thought of that by age 8, a "breakthrough thought" that just about anyone reeling a kite has experienced..
      The challenge in AWE has never been whether the power is available, or whether the technology exists to fly a kite, or whether a powered reel can theoretically extract some intermittent power..  The challenge is to use the wind's energy to generate electricity in an economically-superior way.  The entire charade you've watched for the least decade is that everyone can see the power is there, but the skills required to extract it go far beyond the ability to fly a kite. Still, most "teams" are stuck at kite-flying, really, still mostly just trying to master flying a kite at all. let alone making much, if any power, and let alone doing it cheaper than existing wind turbines.
