The one I remember is the nets over NYC where people spend the day climbing among the nets, with the supporting kites piloted "for the honor".  (not sure what happens when the wind dies out, but hey, why examine fairy-tales for accuracy?...) Other than that, let's not forget the importance of dropping spores for spotted mushrooms, and dropping cinnamon-scented notes to gerbils!  :)

    I sent a bunch of kids climbing through the windsock tail of this kite (attached) when it was flying last weekend... Sadly, None of them got thrown out.
    However one of the leaders did scream for help as she got dragged along the beach by a  Peter Lynn skin 4 line kite... The scream was through concern about her trousers being pulled down by the sand. How we laughed.

    Let's note that there is no evidence that Alfredo "copied" Gabor, but may have independently invented the same concept. As for the idea that Boeing had a "dismal record" in wind energy, Boeing has a different take, and one of our top AWES Forum members, Chris Carlin, was one of the talented engineers-

    Congratulations on being copied, Gabor.  You were there first.  Perhaps a scale model should be built and tested to see how much energy it can bring home.
    I think it was Paul Gipe who pointed out the dismal record of companies like Boeing in wind energy.
    I think it was they who had designed wind turbines with aluminum blades built like airplane wings(?), way back in the day.  Just heard about that recently - I have no references to it.  The rumor-mill or fact?  Not sure.

    It’s fact. I was working there at the time. For those who don’t know about 1969 Boeing and hence Seattle had a terrible depression because Boeing had sunk all it’s money into the 747. We went from 120,000 employees to 30,000. from say 1969 to 1971. Anybody interested can look up the numbers but that’s roughly right. Hence the expression “will the last one to leave Seattle please turn out the lights.” The wind turbines were in a place called Boardman Oregon. I never much thought about it but I suppose the blades were aluminium but composite technology wasn’t advanced enough to be considered and Boeing at that time was very much a metal bender company. I was working controls technology on missiles but had conversations with the people working the wind turbines which were viewed as a diversification effort. They also got involved in the early days of computer managed grids - SCADA so called I seem to remember. As I understand the Boeing design used active controls through blade pitch variation to maintain 60 hertz output and stay in phase with the grid. This in turn imposed very tight control loop gain requirements on the rotational speed control system. What somebody neglected considering in the loop design was the effect of high loop gains on the bending modes of the blades and their interaction with the gearbox dynamics. Net result was the units worked fine for a little while but rapidly ripped up expensive gearboxes. There may have been other problems but that’s the one I know about it. Also keep in mind there was a fuel crunch in 1973 when all this was going on. When the fuel crisis went away and the airplane business picked up Boeing dropped the project as not being the best allocation of resources. This was true of a lot of things Boeing diversified into at that time including hydrofoils and road laying machines. Some of the lessons learned in the windmills eventually influenced or prevented similar mistakes on unrelated airplane programs. Technology migrates with the people who design and analyse things.

    By the way given technology of the time there was nothing wrong with building the blades as high aspect ratio wings. The modern blades I suspect aren’t dissimilar to the wings of some high altitude long endurance drones. The only real differences I suspect are the amount of twist and the structural concept particularly near the hub. I also suspect at the time something closer to a straight wing was used for simplicity.

    Haven’t run any numbers but good luck on finding a structure which would support the structural compression loads and be light enough to float itself. Easy to test. Make a carbon fiber cylinder of a weight floatable if evacuated and then evacuate it. I suspect it will crumple long before it floats.

    Doug, it can be profitable to examine conceptual scenes for mechanical feasibility. Your recall of the net climbers from former post is neat. Climbers of towered turbines serve many purposes. In kite aerotecture, in kite recreation, in various practical working AWES (electric generators, traction servants, and lifters, etc.) may well need various small or large nets; some of the nettings will fall-arrest, be climbed, etc.   And for feasibility, one watches the weather and wind, of course, and makes appropriate calculations for intended operations.


    When the winds goes to inadequate? Various solutions: lower the system, drive the system, reduce upper mass, disconnect and glide, etc. Such questions and solutions are invited to become pointed topics on their own.  The other topics you just mentioned may have dedicated topics on them; you touched upon the large realm of planting or seeding or distributing things from kite systems; good!  And you touched upon the huge realm of dropping things that had been kite-system lifted; good topics on their own.


    Thanks again for recalling the net-climbers. If the net is high enough, the climbers might also be wearing rescue parachutes.

      Start with a net like this... (attached.)
      Triangular parts are to be kited,
      Overall outer net is to be stretched outward & anchored.
      Upwind edge is to be the most released upward to wind.
      The inner circle holes are taught in tension. (what can be spun inside there? Trolley spinning soft sail bol kites or daisies?)

      How many layers high can this net be kept stable? Are higher layers made of fewer concentric hexagon rings?

      Can the spinning in hole components be joined between higher and lower net layers to make a flying lattice?  By daisy stacked chains maybe?...
      The overall net of chains like a swarm of generators...
      Tethering of the triangles can tweak the overall flying characteristic so each part is lifting... Can Daisies be made much more lifty? ... YES!  Lots.
      What size does that make the holes then?
      How does the plane of the circle and daisy spinning interact on the lattice?
      Can something like Pierre's spinning winders be used to adjust pitch of the spinners?... Yes.
      Can a matched array of winding gear adjust the triangles for all lifting and most upwind highest ... so that the whole net is filled by gulping a wide wind catch?.... Yes.
      Do the spinning sets coming down in spun string ring sets look like gills?  With a good imagination.
      A lot more drawing to do on this one.

      Reverse pumping or towing of kites to maintain flight in calm is now well established. TUDelft and GrenobleU have done studies and prototypes (Roy Lozano esp.) KiteLab Ilwaco demoed phased circle-towing in public years ago, which is suited for iso-meshes. Step-towing is well known in HG/PG circles. Parasailing is just towed kites, and modern roots date back to Bell at least, using a horse. Just add nets, as the app requires.

      Rod's choice of mesh is also my favorite quasi-standard mesh geometry, but the choice of WECS is not too obvious, since many principles can be applied, basically anything light one can hang by string, like Daisies, flygens, flappy-wings, looping foils, etc.. It would help us if we had a battle-of-the-kite-WECS to down-select default units for lifting from the pool of hopeful monsters.

      On Monday, the first day of the kite super-festival here on the US NW Coast, KiteSat flew for several hours and attracted lots of curiosity. The current testing phase is to charge the unit by flying, then discharge the 3 LEDs, in cycles, which produces a rough one-to-one ratio of flying-time and discharge up to about eight hours. The small bugs in the design seem to have been worked out, and the unit has been working flawlessly for some weeks now. A sled kite with a bucket-drogue carry-bag has been selected for the product, since the KiteSat unit fits nicely in the bag; commercial packaging problem solved.

      On Tuesday, the ground-station control bar based on two sand-anchors was tested again with a 4.5m2 NASA Power Wing. An 8m2 KiteShip OL had dragged the anchors two days before, so the anchors were set deeper, and the smaller kite reduced power. Nevertheless, the NPW busted a 500-lb Spectra line within seconds (but the anchors did not drag). The linebreak was like a small pistol shot that caused many to look up and notice the collapsed NPW slowly coming down. Next time the lines will be 1000-lb Purple Plasma. Despite the short tests, good control and the comfort of the spreader tube were confirmed.

      On Wednesday, a 2m2 Pansh Trainer foil was flown with a PTO hung with a large inflated buoy on a bungee. Some unease was caused by the violent tossing and surging mass in the sky, but there was no serious objective danger. The elastic was shown to be an effective solution to shocks disturbing the kite caused by jerking payloads on low-stretch tethers. The PTO demo was a compliment to the anchored ground station demo the day before, in that both ideas are intended to be integrated in a single final design suited for endless work applications.

      Yesterday (Thursday), began with low wind; no novel demo was rigged and flown, but social networking went on. Maybe today a large tarp will be set in the sand around its margin to create a ram-air fall cushion for kite man-lifting safety. If it works as intended, it should be safe to fall on the cushion from an adjacent park structure. Depending on the available flyers, crowd issues, congestion on the main kite field, and so on, the climax to the week of demos will be to fly an iso-dome lifted by kPower's six 22m2 Peter Lynn pilot-lifters, as operational testing for Aerotecture. There will be a careful process of safety validation, and any human flight will occur only at the waning festival, or just after; no rush. Will report after the Festival as to how the big kite demos turned out.

      Seems like every time you fly a kite you have problems with the basic idea of anchoring and tethering, with the anchor and tethers (kitestrings) repeatedly failing, kites running away and falling from the sky, etc.  Why do we talk of powering the world when we can barely even fly a kite?  Half a decade of test test test and you still have trouble just flying a kite?  At this rate of progress, when would we power the world?

      quoting: "the combined electrical output of the three turbines was 8,251 megawatt-hours — enough to power about 1,000 average Northwest homes for a year. Project manager Peter Goldman called the five-year, $55 million research project "an absolute success.""
      *** 8251 MWh is worth about $330,000 at 4 cents per kWh.  The repeated theme is "metal blades", "the turbines were dismantled", "the turbines were sold for scrap metal", etc..  The force that got wind energy producing any semblance of reliable, economical power is known as "farmers with welders" where Danish country folk started building very simple stall-controlled machines in the form of a pedestal fan.  Hats off to any pioneer who could have made multi-MegaWatt machines back then, but they repeated the "Grandpa's Knob" failed approach of using metal blades.  Don't forget, one major symptom of "The Professor Crackpot Syndrome" is to build early prototypes way too large, burning through money way too fast, resulting in failures that are way too expensive.

      *** Yes that's what I was getting at when I suggested building a small blimp or other floating model as a start, just to see if the engineering is possible with today's materials.  Part of "The Professor Crackpot Syndrome" is to propose LARGE prototypes when the principle has not been vetted at a smaller scale.  Often the excuse is that the design cannot possibly be economical unless it is built at some huge scale.  But, back to Earth, why spend a million dollars to watch a large structure collapse when much could be learned from way-smaller models?  I wonder how much experimental work has actually been done in the "vacuum-filled" floating structure area?  Do you suppose anyone has successfully built and deployed any such vacuum-filled floating structure yet?  At ANY scale?  Seems like a tantalizing concept.  Even some relatively easy computer studies would give a pretty good idea if it could be done, right?

      Doug,

      These experiments are novel and the gusty wind conditions are real. Those who fly kites technically, and want to keep line-drag in check, are familiar with busting lines to dial in a design. Its like specifying a fuse. Its also a gift, that the breaking of lines or dragging of anchors signals that the WECS is on the power. Those who do not break lines are not trying.

      You notice correctly that things break routinely in modern test engineering. This is a core empiric method, called Test-to-Falure, to get essential data about load-limits, failure-modes, and just how light and smart one can build, for cost and performance, with verified reliability. Its clear that it "seems" like "problems" to non-specialists, but once explained or practiced, it makes sense.

      Aircraft structural performance and reliability was revolutionized as engineers learned to design wings lighter than needed, then tested them to destruction again and again, making improvements with each fast design cycle. In recent years, design simulation cycles with failure modes have grown in value. This is exactly how the developers of AWES proceed, as standard AE best-practice.

      Maybe Chris would be the best guy to contact Alfredo on Gabor's behalf, but not to contend over priority, but to collaborate on further R&D. Note that kPower tested a partial IFO this spring (small-scale energy airplane concept suspended by a safety tether to a pilot kite).

      Doug overlooks that Boeing's accomplishments were as a wind-tech engineering-science project rather than a business lesson about energy price cycles. The tech business lesson is how Boeing's technology leap flowed naturally into GE's current turbine sales leadership, just as the two companies have for generations led in aerospace markets in tandem cooperation (Boeing makes the planes that GE provides with engines).

      Composites are in fact mentioned in the story, and we can guess this was S-glass, which had become mainstream at that point, but carbon fiber too precious for an industrial-scale experiment. Aluminum turbine blades would be awesome, but many odd factors like radio-interference radar-clutter effects also drive materials selection, including what the founding engineers just happened to establish as standard. Metal AND plastic are in fact the norm.

      *** Joe, no need to bother.  We don't need a new encyclopedia every time you guys want to squirm your way out of another questionable statement.  Everyone knows there are "historic instances of fall-arrest and climbing of nets."  Think boot-camp and circuses, cargo nets, boarding tall-ships, tree-houses and climbing wind-turbine towers.  That's all well and good, but you said: "some of "the nettings" (as though they already exist) will fall-arrest, be climbed, etc.", as though this was a fact.  I wouldn't have mentioned it except you guys seem to have a consistent problem separating fantasy from reality, and real systems from mere concepts on paper, so if you state that "the" nets hanging from kites "will" fall-arrest, "will" be climbed, versus proposing with less certainty "could perhaps be used for fall arrest", or "could possibly be climbed", I'm just trying to discern which you really mean, "will" as though it is a sure thing, or "could" meaning "maybe, if someone bothers".

      daveS concludes: "Composites are in fact mentioned in the story, and we can guess this was S-glass,"

      ***ding ding ding*** Boeing used steel for blades, with poor results, and NASA used aluminum.  You can "guess" whatever you want, but you're reading Boeing's own public relations material where they would like to take credit for as much innovation as possible; but really, other efforts succeeded where theirs failed and were dismantled.

      This is how it works:  You get large companies with lots of big salaries and big egos.  They make decisions like using metal for blades because that's what they're used to using, design-by-committee, with the main financial motivation to "just make it work for now" (they are on salary), then "get more funding for their program later", whereas the "farmer with a welder" just needed to make economical power right away, with no room for excuses or getting paid to fail.  So you have the PhD's versus the farmers with welders; and it is well-known who won.

      Doug, I am not sure who the "we" are.    I respected your question and intended answering; so there is a need to "bother" to serve the topic with concerted effort.  The topic thread invited what might amount to a robust kited-sky-net text, even up to encyclopedic levels. You may contribute to the project, if you wish.  It is fine to question statements politely and in good faith.  Answering these interesting challenges is not a matter of squirming for me, but a matter of sincere effort to advance AWE in its kite-energy sector especially.   The intent of the phrase you put in focus was to be in context of kited sky nets, not the cargo nets tensed by boot-camp and circuses.  But kited nets. 

      So, some start: 
      1. I had some other starts in mind that I will get to, but your very retort gave light to something: In our forum it has been shown that rope-moored ships are kite systems. You just mentioned ships. The nets on such cargo ships indeed are nets held by the kite system (ship, a large paravane). 

      2. Yes, some historic and contemporary kited nets have occurred and are occurring as we type and read.  Here is one: take the net harness of kite hang glider pilots; those nets are arresting the falls of hang glider pilots of the past and of today and will so tomorrow. 

      3. There are videos online showing some persons climbing a kited net during paraglider incident mitigation action; the pilot has a collapsed wing that is kited; he climbs the harness net and shroud net of lines to try to gain control of the collapse wing or bring it in to allow rescue chute to have the open air.  

      4. I have climbed a kited net where the net is minimal, the tether of the kite system.

      5. The kites during WWI had launch teams that worked with cargo nets and nets of launching lines; there is indication of some climbing of the nets during operations. 

      6. There was in forum some description of using nets to lift things for various reasons; this may be expanded in this topic thread. 

      6. The "will" thing ... future: 
          For one:   In forum I have indicated that I am personally aiming to have inclined nets held by kite trains to provide a slope for foot-launch hang gliding.  Such would be in lieu of constructing a compression based structure for doing such activity.  

      I trust that I and others will probably expand the kite history and futuring with regard to kited nets for fall-arresting and for climbing and other uses.  

      Consider using kited nets for: 
      a. Lowering flygen charged batteries. 
      b. Lifting batteries for flygen charging. 
      c. Holding rescued animals. 
      d. Transporting grain. Line the lifting net with a textile that won't let the grain leak. 
      e. Dragging the ocean to collect trash. 
      f.  Commercial fishing using nets moved by kite systems. 
      g.   .. 
      {pause; the topic invites more and deeper on similar slants.  And even full detailed specifications! And reports of uses.  Lessons.  Supply. How tos...

      Doug seems determined not to credit Boeing's leaps forward in wind tech, such as to create the world's first multi-unit farm at the megawatt-plus scale, with many innovations like the massive tube towers. The 300-ft blades running for several years were a huge advance in the state-of-the-art. Nobody can argue Boeing is bad at business. In fact it was smart to let its partner GE successfully develop the wind power market.

      The appealing but questionable idea that "farmer...welder" types "won" the wind power race is only true in rare cases, best exemplified by my old friend Michael Osborne who not only pioneered the first modern wind farm in Texas, but rode the wave all the way to Texas becoming number one in US wind power, for which Michael is given the most credit of anyone. Most of the small guys doing small turbines never made it to the corporate boardrooms of industrial wind; dominated by large players like Vestas and GE, which depended on large scale experiments to validate the tech for large scale adoption, even if the farmer-welders did not.

      Doug does not draw stark factual comparisons between his own languishing wind tech business, USWindLabs, and the big wind industry winners' stories. Boeing could once again pioneer novel wind tech on a grand scale, as a hugely profitable business. Boeing has a nice shot at leading in airborne wind R&D, given its aerospace prowess, but needs to once again to step-up to that challenge as it once did with HAWTs, and market luck matters (price of oil). Boeing patenting an IFO concept seems more promising than if Boeing mistakenly expected a rigid drive shaft to scale to the high altitudes being targeted.

      Gipe is not a strong choice of prophet or expert in airborne wind tech, since he did even know airborne wind tech existed (until Joe and I contacted him) and misunderstood Makani's kite plane's high-speed sweep with small frontal disc area, but we are intending to apply the testing standards Gipe proposes as the tech duly matures, and we remain on good terms.

      Take away - Clews difficult to handle (obviously). Head of the sail tended to be too low, despite manipulation of the clews.  Hypothesis: lifter kite too small to hold the head high like a mast does on the sailboat.

      Kite kill test successful as both people released their respective sheets and the spinnaker collapsed.

      Following the experiment I received RC airplane training in preparation for experiments with tethered gliders, as per the interest of the aerospace team. We have been collecting data for a National Science Foundation grant application -  primarily using the Gomberg Falcon. We intend to also use a parafoil, a morse sled, and, if possible a tethered rigid wing using "autopilot" RC controls, which apparently are standard COTS hardware these days. 

      The idea of the study is to model a kite's behavior in chaotic wind environments for predictive purposes.  

      The new kite field is actually a pirate RC airplane field, where my trainer loves to "dog fight" with his friends and slope soar in an adjacent retention pond.

      Kite
      Patent US6062510 - Kite


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

      Comment, study, and furthering on the theme:

       

      Caros De La Melena provides a family of kited sky net opportunities that may be explored for AWES. The net may be made of conductive lines, non-conductive lines, or a combination of conductive and non-conductive lines.  Net lines may be translucent or opaque. The net lines may be flat, round, or even streamlined.    Notice the opportunity for rapid formation of non-net sail appliques that may occur. 


      Notice that non-flat net bases may be flown upon which the rapid applique choice may apply. Complex broken-plane polygonal net surfaces could be formed. The kited sky net provide a foundation on which may be applied experiments.


      Net nodes could be connection points for branched sub kites. Quick-attach points!


      Cloud-water collecting? Radar-visibility sky markers to help organize airspace? Ionization of the air? Specialized antenna for communications?     Reflecting the sun to multiple the sun-impact at some point? 

      ???


      Notice that we may extend the concept of "net" to forming parafoils and other soft kited wings with various levels of porosity at a region of the wings or for the entire wings involved. E.g. take a crisp parafoil of very low porosity; the wing inflates rapidly when placed rightly in the wind; now morph that wing with "net" as an action verb meaning here to cause the wing to morph or be modified to have higher porosity in some sub-sector of the wing's surface or in all of the wing's surface; a result will be a change in the aerodynamic performance of the wing.  Note that the changes of performance may be wanted to face certain challenges or needs (safety, blow out, extreme storm-wind kiting, de-powering, ... ). [verb: net]: Net to altered opportunities.

      Joe you can stop now.
      There must be more important things for you and daveS to do with your time than fixating on trying to disprove by Wikipedia articles every fact I offer.  You've provided many many links to blimps with ropes hanging, etc., none of which involve "kited nets".  Forget sailboats - no, the world is not going to start calling (redefining) regular old sailboats as "kites" just so you and daveS can "win" another of your beloved "arguments" which, apparently unknown to you two, usually are nothing but weak attempts at redefining words.

      Advertising banners towed by airplanes are NOT kited nets.  Hang-glider harnesses are also NOT kited nets in the sense you boys have been advocating.  Hang gliders are only called "kites: as a version of slang - they are airplanes and the people flying them are pilots, and a mesh as part of a harness is only one option.  What's next, a fixation on nets for holding items on the inside of car doors as net-based transportation?  Maybe the cars are really "kites" since they must negotiate in air and have weight, right?  The silly thing is you are likely to take a sarcastic question like that literally and we'll be assaulted by wikipedia articles "proving" cars are indeed kites.  I've learned there really is NO LIMIT to the illogical statements of daveS and joeF. You guys are way off on your own planet, and that's an understatement.

      The question was whether we will ever get to a point when people are climbing around on nets dangling from kites.  You stated it as a certainty, I've pointed out that perhaps it is not certain and you've overstated the case.  Nobody needs a hundred pictures of ropes hanging from balloons in WWII, but it seems that the one thing you HAVE proven is you CAN'T actually FIND examples of people climbing nets suspended by kites, no matter how hard you try (and why would you really?).

      You guys purport to be running a group dedicated to airborne wind energy, but then degenerate into a steam-punk fantasy-world harking back to science-fiction thinking from the 1800's, endlessly offering brainstorming of unrelated things kites could conceivably be used for BESIDES energy production, instead of the stated mission of the group.  All fine and dandy, but I wish you'd both stop pretending that your fantastical half-baked kite-fantasies are factual statements involving projects underway that WILL have characteristic X or feature Y.

      The more you, daveS, Wayne, etc. go on with your spotted-mushroom fantasies about kites dropping notes, delivering packages, and leaving actual AWE development to "Jesus", the less anyone is going to take any of this seriously.  Of course if all you are looking for is to have fun on the internet, great, stop censoring the humor injected by others, and let the rest of us have the same freedom you allow yourselves and maybe everyone can stop complaining.

      And the idea that any two people this far into la-la-land can sit around badmouthing and nitpicking the musings of others, endlessly trying to find ways to rationalize censoring things you don't agree with, is one of the biggest jokes I've ever seen.

      Late yesterday I rigged a 1x4 m section of cotton net with guy lines and sent it up under a Gomberg Pocket Sled in medium wind. The kite had no problem lifting the net, so it could be a workable rig for, say, catching drones (net landings), adding more kite for added payload demand. Its basic low-tech, but the inherent properties of nets are subtle and powerful, and the twilit little experiment hinted at far greater things to come.

      In fact, Sky Nets seem just as promising with kites as networks are for computers. We have hardly begun to explore the abstract fundamentals in terms of topology, network theory, and so on, and endless practical applications and methods. Joe is mining gold with this topic, as a sort of scatter-plot across the Sky Net concept continuum. Its a pretty good expert prediction Joe, I, Rod, and others are making- that Sky Nets WILL find great applications; let history decide.

      A decided trend at WSIKF over the last decade is for kites to be increasingly networked as trains, stacks, arches, etc., as the practitioners continue to explore latent possiblities. Open-AWE R&D is strongly driven by mainstream kite trends, and the Sky Net trend will continue to flourish in the Low Complexity school as an alternative to High-Complexity computer-networked controls.

        Doug, 
        1. I am not fixating on disproving any fact you might offer. Please, instead of shotgunning, be specific on statement; let us deal with specific statements Thanks. 

        2. It seems clear that you and I are not seeing nets in identical ways. We need not. Let's see if we can hold each other's perspective as is.  I sense that you do not see nets where I see nets. That is fine with me; I get to see the nets where you might not; that is no problem with me.  Net has been in conversion in forum an undefined term yet, so the matter is somewhat open.  Similarly, I see kited nets where it seem you do not see them; again: no problem here; I will keep seeing the kited nets and advance my research over such. 

        3.  Your push to have me stop seeing kited nets where I see them is a push that has little impact.  The target of this forum is RAD; and kited nets seem to be part of the RAD universe. 

        4. You urge to forget sailboats, yet many AWE schemes involve sailboats and other water wing involved structures. So, I will not be forgetting sailboats. Sailboats come in a huge variety; and that variety seems to be expanding yet through the years. Kiting has changed the variety of sailboats. Energy-producing systems that may involve sailboats are perfectly welcome in this forum.   I am not sure where you springboarded for the sailboat-forget push, but I am guessing that maybe you bounced upon seeing another mention of tether-moored cargo ships being kite systems; we have many mentions over the years about huge ships being wings of kite systems; and some strong patents involve large water hulls as part of AWES.  So, those branches of AWE will probably continue to be developed by some researchers.   Their notes are fully welcome in this forum.

        5. You seem to like the word "redefining" in critique over my pattern and style of searching for and finding AWE matters.  Only occasionally are words well defined in the forum.  If you wish, please start a dedicated topic in the form that focuses just on some word and the defining of such word. In some cases such exercise may turn up some great ideas.    One word per topic; and then focus.  But the repeated hits of "redefining" does not hold much meat until you propose a definition; at that time, someone could note that they are staying within your definition or going beyond the borders of your definition. In either case, discourse will be about things, hopefully AWE matter.    I will await for you to start some topic that aims to get definitions for some word or phrase.   Thanks.  

        6. For example, I see kited nets in many advertising banners towed by airplanes.  You declare that what I see as kited nets in that field are not so for you. That is fine.  I do not have a pressure to have you see kited nets there, but I offer that view for anyone reading.  And I am willing to support my claim: The towing airplane is the anchor of the kite system; the tether tow line is the kite system tether set; part of the towed net is part of the kite system tether set and part of the wing set of the kite system; the advertising material supported by the kited net forms more of the wing set of the kite system. A kite has anchor set, tether set, and wing set. The air media has the wing set here fly in the air.   I see kite system in the scene.  You do not. Life is still fine.  

        7. Doug, you apparently are also not seeing kite hang gliders as kite systems.  Fine. For nearly 50 years I have easily seen kite hang gliders as true kite systems. The anchor set is the pilot's mass held by the kited net. The tether set involves the kited net and the tethers between the anchor and the wing set; the tether set consists variously of one line up to 8 or more lines (hang lines  to the harness net form an extension of the net/tether set). Then the wing of the kite hang glider is set into the air and the resistive couple is set up between the anchor set and the wing set; kiting occurs; the system has the parts and sets of a kite system and does true kiting. By those accounts I see the kite hang glider as a true kite system; the anchor sometimes is fixed to the ground at the start of launch and sometimes moving fallingly through the air; in one instance the system is a fixed-to-ground-anchor kite system; and the free-flight system is a gliding-kite system where the anchor is moving. Parasailing with boat-tow is a true kite system.  FFAWE of kite types mostly... they are true kite systems where the anchor is another wing set (indeed, all kite systems's anchor set may be seen as a second wing set).   It is OK, if you do not subscribe to the definition of kite.  We collect definitions of kite on a special file in open net. 

        8. I am not yet seeing cars as kites, Doug. You proposed that topic.  I am not seeing cars as kites. 

        9. Please, again, simply present a statement that you think is illogical; set up a topic to deal with the question. Then argue what you think is illogical in the statement. Just shotgunning blanket characterization of posters' works might not be as effective as politely putting up focus on a statement so all may have a clean try at the logic or fallacy set that might be involved.   Just hitting and running makes for a kind of hard-to-deal-with situation.   

        10.  Your rephrase of the topic shunts the broadness of the intended topic.  The topic will be covering climbing on nets and other parts of kite systems, but will be covering a great deal more. Guesses at futures are fine. My guess is that more and more climbing on kite-held nets will be occurring. 

        11. Doug, it now seems evident that differ on another system.  Yes, I see kytoons as true kites. If I read your remarks correctly, you do not see the kytoons (kite balloons) as kites.  That is fine; we can do AWE with kytoons, even if you do not hold kytoons as kites.  

        12.  I described climbers of kited nets.  Your not "seeing" as I do is accepted; I will keep on file that you do not see my examples as I do.  Be at peace, I suggest.  

        13. A very consistent difference that seems to keep getting you excited is the matter of whether or not a working kite system not directly producing electricity is AWE matter.  Since day one, this forum includes both sectors of working kite systems: those that closely produce electricity and those that produce other forms of energy for doing practical works.  You are welcome to only look at and develop only those AWES you wish. But you are encouraged to stop trying to hit away the other large sector of AWE, that which produces energies that are not the electricity format.   You may remain good citizen of this forum by just focusing on what areas interest you. But it is not good citizen of this forum to use large bandwidth to repeating a drive that seems to deny part of the essence of this forum. This forum is for lifting, traction, releasing, reflecting, shadowing, air redirecting, antenna holding, transporting, aerotecture by kite, etc. AND producing electricity for electrical loads. Each poster is free to form topic in either or both large sectors of AWE. The essence of this forum includes some non-electricity kite-energy systems.  A classic simple kite system already is converting wind's kinetic energy to other forms of energy beyond electricity.  Note that use of other forms of energy may be a path to saving the need for electricity. 

        14.  Doug, it seems you have a need to wrestle with the word "will".  I am not meeting posters who have foreknowledge as God might. Humans seem to coast with an acceptance that the use of the futuring word "will" has provisos that are not totally rehearsed every time a guess of the future is made. That is, humans seem to use "will" with the proviso that the future might not unfold as described.   Please see if you can quiet some on this matter.  People are predicting with the unsaid proviso that the future might be shunted into an asteroid stopping of all earth activity.  Consider quietly adding "probably" when you see the world "will" stated by people. "Such or so will be occurring." to "Such or so will (probably) be occurring."  And just how probable could be argued. Probability might be very low or medium or high, etc.  

        15. Doug, you need not be comfortable with brainstorming tactics; but please consider letting such tactic be left in peace, as brainstorming is a robust tool used in problem solving, design, experiment preparation, critical thinking, and inventing.  The tactic has been continually used in some AWE circles. You have shown keen ability to use the tactic.  So, please just let other posters do brainstorming shares when they do. Sharp genius will occasionally find springboards from brainstorming shares.  

        16. The forum hopefully will not permit soul-God judgements over posters.  Some moderation is occurring in this new era of the forum in an effort to shunt such personal attacks.  Hopefully the moderators will catch such and send the offers back to the poster for reconsidering the text. 

        Best,

        Bravo Ed, 

        Simple spinnaker-flying without a mast is definitely awesome. It will amaze further when the spinnaker is routinely deploying and furling from a sock, vigorously modulating the drag force of the overall system. This is the latest word in the saga of the primordial playsail kite space.

        It turned out the 9m2 was enough to prove the concept. In kite judging, clearly sustained flight above the horizon qualifies. In power kiting, a low angle is most common. You still had reserve tuning capability by flying the pilot higher or extending the lower main line. The 22m2 lifter will test closer to ideal proportion, but the spinnaker should also be flown with the 4m2, and even flown bare, to fully characterize the spinnaker-pilot ratio spectrum.

        It would be nice to add more subjective impressions too, like how the vibe varies with each setback or milestone. This may seem like a "boring" feat, but flying COTS salvage sails in the sky with Earth as the yacht is as grand as our lives get,

        Joe freely makes predictions, as a top kite-energy subject-matter expert. Pros are naturally expected to predict something "will" happen, just as Joe is doing with Sky Nets. Doug's objection is not very realistic.

        At Joe's prompting, kPower flew a scale prototype utility net in public within two days, so Joe's prediction has been acted on already, and "will" continue to hold. Joe has been gathering varied similar and essentially-matching cases, all suggesting our novel concepts and experiments will mostly work as expected.

        There really is no doubt that airborne nets is a legitimate AWES Forum topic for those able to conceive and pioneer the methods. Where else but here are such ideas being so nicely advanced?

        More similarity cases, if Joe has not yet listed them- 

        - Chinese dragon kites in multiple cross-linked rows

        - cargo net under a parafoil TRL9 COTS

        - many modern kites incorporate netting (Revs, Brasington, woven deltas, etc.)

        - net panels are used to tame stunt kites and parachute openings

        - multi-glider aerotowing

        - spidermills are branching nets, trains are 1D nets, etc.

        - traditional cast nets have a flying phase

        - fishing nets generally are kite analogs, with common dynamics

        The whole subject of layered net "blancmange" kites is a wobbly area.
        https://youtu.be/WNj-8Ozh8_0

        How much lift can you command from this stack?
        How much would need to be added to the top layer (if any)?

        The "triangles" are concave catenary edged to stay taught.
        What form of triangle kites would work best here, e.g. able to be set to fly from all directions including upside down as wind moves round 180 deg.... ?

        How densely packed can a blancmange be before it becomes useless / too dense to be effective at the rear?

        I'm a bit wobbly on the specifics.

        Project Kite is a great name for the sort of cohesive overarching R&D vision that has in the past been called by many awkward partial less-intuitive names like LadderMill, KiteGen, Fraunhofer Plan, and so on, the common theme having been a kite-based civilian open "Manhattan Project" to create AWE solutions equal to all challenges. kPower has been using "k plan" as a working name for Open AWE enterprise planning. Project Kite has the winning advantage of being clearly about kites, which none of the earlier naming attempts can match.

        No doubt ghosts and shadows of previous names will linger, but Project Kite seems ideal to present to the world as the unifying name of globally-organized AWE R&D. Not just utility-scale electricity is featured, but all directly useful kite applications powered by wind.
