I don't see anything wrong with relaxed chat around AWE. As long as this chat feeds inspiration to the AWES design and development community.
I guess it depends who / what you see as your greatest enemy / threat (if any)
environmental impacts of your existence
competitor advantages and underhandedness
Loose lips may sink a personal commercialisation plan. Depends on plan applicability to market.

AWE is a massively under-researched. There is a definite lack of intellectual rigour.
Not only mine and on any AWE forum but in the guiding principles of many projects.

Notably, popular acceptance of yoyo as THE AWE power mode, displays an assimilated contempt toward insight.

It would be inspiring to see the results of this paper* applied to more than line tugging yo-yo's.
If I had half the authors intellectual capacity, I'd attempt to apply it to my own systems.

Subject: Re: KitVes
Joe, we have to distinguish between the ideas that lead people actions and those that remain without consequences.

For example, in 1965, the Italian Pier Giorgio Perotto, working in Olivetti, projected and built the Modello 101, that it being known as an ante litteram PC, and 50 thousand of them were produced  (http://www.piergiorgioperotto.it/programma101.aspx). But I cannot say that Steve Jobs, or Bill Gates, or IBM are in debt with him. Actually Olivetti company lost his leadership in the electronics and computer industry because their management could not understand the changing world industry. Infact, at that time, the visionary, charismatic and mytical Adriano Olivetti had died, and conventional wisdom men (FIAT men) like Aurelio Peccei and Bruno Visentini had arrived, and sold the Olivetti electronic division to General Electric. Later Peccei organized the Club of Rome Club and the Limit to Growth movement to "save the world".  

Also Miles Loyd paper and patent are quoted for the high altitude wind power, but his ideas did not lead the European companies working in the field, we cannot say that he paved a path. Of course his aerodynamic and math are elegant, but useless, as for the Einstein math and formula, E=mc^2, that was useless for developping and building nuclear reactors and bombs.

      Note that the Russian turbines-in-a-wing patent recently cited by JoeF adds to the list of related prior art, albeit for  rigid wings.

      This topic has set the AWES Forum record for longest-topic-ever, but with no final sharing of the actual idea Pierre announced. His curious standard of "correct ethical and technical voice" for such opinion prevents his sharing "more details on the forum about R&D related in the present  topic" (but not his random preference for New York psychotherapy).

      In summary: Pierre is claiming here that he has discovered a novel utility-scale AWE solution which must be kept secret, by a silly pretext. It seems more reasonable that the extensive prior art carefully  cited for him in fact adequately covered the topic. We can only await Pierre to someday disclose (or fail to disclose) his claimed inventive AWE advance, by his personal "ethical and technical" standard, in his own time (not RAD time).

      "It seems more reasonable that the extensive prior art carefully  cited for him in fact adequately covered the topic", confirming the main purpose DaveS is  making comments (here about patents) instead of prototoypes.  So Open AWE is in fact open comments.

      Subject: Aerotecture
      Preamble:  http://tinyurl.com/AerotectureInForumAWES to see uses of term "aerotecture" in the forum, so far. 

      That companies may use the term "aerotecture" as part their name does not halt the generic character of the term for referring to architecture in the air. Architecture embedded in kite systems is a proper subset of aerotecture, a more general realm. RAD embraces the kite-systems' subset kite architecture of  the global set "aerotecture." While being in prose within RAD circles "kite architecture" or "kited architecture" may be abbreviated to "aerotecture."  And we know that a LTA kytoon is still a format for a kite.

      A single kite may be a vast queendom of homes, factories, play spaces, and places of love and worship in the sky.  Or something less ambitious down to a simple sled wing kited to hold a bird cage housing a bird on the mend. The Santos migration of one billion persons into the earth sky teases innovation and perhaps action. Staying aloft challenges; use wind and water currents; explore solar assist for light warmed airs; shake hands with R.B. Fuller and others in the design flows.  Who will be the first human to live a year aloft in a kite system? Jim Will has lived aloft in a FFAWE kite system for 34 hr.   Who will be first human to live 70 years aloft in a kite system?  Etc., as I. Newton would oft end some notes.

      Jeremy,

      Its true, that if the M600 manages to survive a year of testing, logging a few hundred nominal flight hours, it will be one of the great aviation feats of history. The converse side is how big a fiasco it could be, if it only crashes, especially if anyone gets killed.

      What would be even better would be a side-by-side GoogleX fly-off against Low-Complexity AWE (like a 320m2 SkySails wing pumping at a groundgen, sponsored by your boss :) ).

      Subject: Technical Kite Group Meeting at World Kite Museum (US Pacific NW reg
      Please contact me or Holli (WKM Director) if you plan to attend. KiteLab Ilwaco will provide extended hospitality to AWE participants, for further AWES technical sharing and demo flying on Friday and Sunday.

      ----------------------

      Technical Kite Group Meeting at WKM

      ----------------------

      Saturday 11AM-5PM (with lunch-fly break), November 22, World Kite Museum, Long Beach, WA

      Premise: The potential of Kites as serious technical tools needs to be better explored, and the knowledge and practices widely shared.

      Format: Initial informal organizational meeting, with show-and-tell of materials; open outdoor demo-flying, according to conditions

      Who should attend: Regional (Pacific NW) kite experts (and anyone interested in specific kite applications). Net-participation is welcomed.

      Discussion Topics:

      Kite Therapy- Chinese medical tradition prescribed kite-flying to get outdoors and improve mood and health. WKM is the world pioneer in the modern therapeutic use of kites with special-needs populations, with dramatic results by simple means, closely comparable in benefit to dolphin and equine therapy for conditions like autism, PTSD, paralysis, etc., and also as a universal low-impact duration exercise and relaxation for healthy-lifestyle.

      Kite Curriculum- The kite is an appealing vehicle to excite learning of every kind. Math, science, and engineering are ideally taught as a tangible hands-on activity that directly connects with textbook learning. Teachers report the experimental flying activity to be a peak enducational experience that creates a learning window to present diffucult material. Students tend to become self-motivated learners. Kites are also attractive to artistic, craft, and sport oriented students.

      Kite Energy- Upper winds are considered to be the ultimate renewable energy source, and a race is on worldwide to develop the technology, with hundreds of active researchers and a diverse range of concepts. WKM and Drachen Foundation are leading institutional supporters of the design knowledge-sharing that  drives progress. 

      Kite Life-Style- Hundreds of new Kite Festivals have emerged around the world. Kites are in the news like never before. A Kite-Sport revolution has occurred, as a green alternative to ski-lifts, ski-boats, and ATVs. Explorers now cross ocean, desert, and polar expanses by means of kites. There is a growing subculture of kite aficionados who practice all kinds of kite flying, as a way of life. Participant safety and satisfaction is a properly technical concern for the professional designers.

      Subject: Makani: Double Betz coefficient: 59% of 59% = 35%?

      Doug Selsam offers the following in this fresh topic:


      While I DO think Makani has the best chance of any highly-funded and highly-publicized AWE effort out there right now, I will note two possibly detractive aspects to the Makani effort:
      ***Double Betz limitation: The main wing, like any wind energy device, is subject to the Betz limitation of 59% energy capture.  But is each propeller also subject to the Betz coefficient as well?  Seems like they are.  The Makani configuration demands that any wind energy be captured TWICE, before it can be turned into electricity.  Forst the wing must capture wind energy to push the propellers through the air, THEN the propellers must capture the energy from the flow resulting from the motion of the wing.  This would seem to be POSSIBLY enough to cancel any advantage of "more consistent winds" at higher heights.  It's one thing to REACH the higher winds at higher heights, but if the method of CAPTURE is less efficient, due to the requirement of a "double-stage wind energy collection system", then the advantage of the higher winds may be at least somewhat cancelled out by the inherent inefficiency - just sayin'...

      Subject: Re: Makani testing a real deal

      Doug Selsam replies on topic hereon:

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

      One might note here, the confluence of Makani, saying they will deploy in Hawaii, next year, producing enough power for several homes, and Altaeros, saying they will deploy in Alaska, again, next year, to power several homes.  One in the 49th state, one in the 50th.  Both "next year".  It is interesting that such projects are always "in the future".  It's always "we WILL power X homes", never "we DID power X homes".  Remember David Fender "we WILL deploy in Fukushima" - we heard the "WILL", but so far there is no "we DID" - why no followup info?  If we were enthusiastic about the announcement, how about some followup?  is it one more example of a project "quietly going away"?
      One part of "the syndrome", named after the mythical glassy-eyed, bearded professor, is to make sure each demo is more of a "stunt" than an actual solution.  Using "stunt" kites, making sure there is always a human at the controls, plans are made for "next year".  Yes, it always seems to be "next year".  And of course, forget powering ONE house - that would be too... "achieveable".  The failure would be too simple: "They couldn't even power one house."  Announcing the powering of multiple houses is a better way to maintain the constant injection of confusion, so there is always an excuse.  A failure to power several houses always leaves open the question "Well maybe they COULD have powered just ONE house..."  The inability to power just ONE house is too cut-and-dried.  Using multiple houses and making sure you are high enough to affect aviation insures plenty of "understandable" obstacles to serve as excuses, so that whatever part of the project actually emerges, if any, can be tagged as "successes" even if they fail.  I'd say let's put some emphasis on the results rather than the promises, of AWE.

      Doug Selsam opens new topic thread hereon:

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


      A stated advantage of AWE is increased capacity factor due to more consistent winds aloft.  It may occur to some that the intermittent cycle of kite-reeling, where power can only be made PART of the time, would seem to be just about enough to cancel that stated advantage of "more consistent winds aloft" by "less consistent energy capture".  What is the use of getting to winds that blow 70% of the time versus 50% of the time, if your system to reach the 70% winds can only capture energy 70% of the time.  Do the math!  (70% x 70% = 49%)    Just sayin'...

      One day I noticed KFI, the most listened-to radio station in America, went silent.  Reason?  The broadcast tower elevating the "50,000 Watt Blowtorch" transmitter, which was within miles of my Fullerton residence and the Fullerton airport, had been hit by a small plane.  The couple flying the plane was killed. The tower collapsed.  Of course the transmitter tower was on all the charts, but it was really "just a matter of time" until the human factor guaranteed a disaster.  My take is that high-altitude, experimental AWE systems should be initially deployed away from airports and flight paths, if possible.  Lower height systems near airports might be less of a problem.   Just sayin'...

      Fair warning to all, that the highest standard of engineering-science in AWE is an advancing target, so the homework never ends.

      Starting from the modern view that Bernoulli and Newtonian Lift are complimentary, not contradictory, the good professor (and Boeing Fellow) Doug MacLean then goes further into the Alice-in-Wonderland physics of the aerodynamic Far-Field, to the very border of classical physics. A shocking revelation is how partial our favorite mathematical tools are (and how far they have to go); to fully explain even the most basic aerodynamic concepts. A lesson updated here is the importance of careful span-wise design for optimal wing performance (as opposed to local fixes wingtip devices for induced drag reduction).

      Note that megascale kite arches and domes, compared to smaller more spaced-out discreet AWES units, better exploit the Far-Field, by a scaled-up wing-in-ground-effect below (and even drawn up some by the progressive vacuum field of space above). The atmospheric pressure gradient created by the gravitational force and Earth pushing back up is a part of the complex real-world lift picture.

      Some discussion about this:


      Doug noted:

      And this is relevant because... ?

      Because Google returned the story in response to a search for "spin basket"?  Because you want to call the helicopter winch "a tether"?  Out of desperation to make a relevant comment of any sort, even if it is irrelevant?  What's next, picking your toenails as AWE?  More dogs chasing tennis balls?

      ~ Doug S

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


      Then JoeF notes relevancy to AWES RAD: 


      Topic-poster JoeF replies to DougS' above questions:

      1. I did not use Google search over "spin basket" but rather saw the news spot on TV and then found the article online.  


      1.1 The post was out of a natural affinity for posting relevant RAD matter. Thanks, DougS, for questioning the relevancy of the post. Maybe my clarification hereon will help show the relevancy.


      2. I have oft wondered about the challenge of wake-induced dashing of tethered wings. CAT is a significant matter for most aircraft including AWES. The CAT of the helicopters have taken the life of my hang glider friend when he was flying a FFAWE system.  The wake of helicopters flying near AWES will be an important matter to AWES pilots, as the wake of a helicopter could trigger an unwanted downing of an AWES. Helicopter pilots will probably need to review their relationship with AWES; FAA and like bodies very well need to respect the needs of AWES with respect to helicopter wakes.  


      3. Upon seeing this story's views I envisioned a possible solution that I want to share that may affect such specific kiting as shown in the spinning basket story, as well as other AWES scenes. See below for my envisioned solution for the rescue-helicopter-held-tethered-basket-wing arrangement (a true kite system where the spinning basket is converting the apparent wind of the wake into unwanted motions of the basket).


      4. There will be rescue events, I believe, but hope not, in AWES plants where helicopters will be involved.


      5. Single-line tether set for rescue stretcher or basket has its kiting response in the wake. Two-separated lines in the kited stretcher or basket has its different dynamics. These are worthy of study as kite systems.


      Envisioned possible solution regarding the rescue basket spin:


      Have on the basket a shape or set of vanes that will alter AoA upon initiation of spin; effect such control of such shape or set of vanes by relational smart reading relative to the axes of the helicopters. Sensors could direct the vanes to counter the spin; the wake energy would thus be used to counter the spin. The kiting of persons in basket wings kited below helicopters may thus avoid spinning of the wing basket.

      Subject: Re: Makani: Double Betz coefficient: 59% of 59% = 35%?
      Its nice to see Doug is still willing to post his technical opinions, even if they are moderated for duly cordial style. We already see a renewal of the AWES Forum, by the return and growth of mild-mannered participation. The value of technical critique is greatly enhanced by professional politeness.

      The Double Betz Limitation conjecture for Makani's turbine-on-a-wing AWES was first presented several years ago on the AWES Forum.* It was then concluded was that this factor did not by itself predict (negative) ROI (until airspace market-cost is quantified, and strongly drives up overall cost).

      A more basic early predictor of AWES effectiveness is power-to-weight (given exponentially higher cost by lower power-to-weight). By this measure a high-enough power-to-weight turbine-on-a-wing can beat conventional wind tower, by operating effectively in far better wind (not easy for Makani's low power-to-weight architecture). In the long term, with advances like graphene kite WECS dense array lattices, AWES may reach nearly 20% frontal airspace efficiency, still limited greatly by the energetic cost to maintain the minimal required mass aloft.

      ------------------
      * In its total frontal airspace, Makani's primary wing harvesting efficiency (ordinary looping-kite mode) is well below 10%, and the dual-mode symmetric-foil turbine rotors somewhere around 40%, so top predicted efficiency is somewhere below 4%. Betz limits are so far out of reach for most AWES concepts, they hardly even apply [KLG 2009; Costello, et al, 2013].

      Subject: Re: Kite-reeling: intermittent cycle cancels altitude advantage
      The Springer AWE book diligently covers the math and test data of reeling cycles, honestly noting expected cycle losses. In no case does the return phase loss fully cancel the altitude advantage, even in early designs. Its a fully-acknowledged problem, with many alternatives to explore.

      On the positive side of reeling, the minimal mass of a pumped tether energy transmission cancels AWE's major altitude advantage far less than the worse options; like the energetic cost of holding up electrical conductors or giant driveshafts. At least early reeling AWES reach 2000ft easily, and can scale further, but Makani's M600 seems stuck at 1100ft, and driveshafts even lower, and will not further scale easily. Often (esp. nightime) a calm surface inversion exists, while at 2000ft the prevailing wind is actually enhanced, and a WECS in the better wind beats an idle WECS becalmed low.

      KLG/kPower's nonreeling and short-stroke crosswind pumping cycles are designed to least cancel the advantage of upper wind. The third-party reeling studies serve as a vital performance baseline, just as "candle-power" serves as the classic photonic yardstick, even if candles never were the brightest light.

      Hopefully Doug can present his own early AWES concepts to compete with current reeling performance at 2000ft, rather than only offer basic review of well-known issues.

      The local CFIT accident Doug reasons from was a case of pilot-error. The tower was rebuilt. 

      AOPA reported- "NTSB examiners concluded that the probable cause of the accident was the pilot’s inadequate visual lookout and failure to maintain altitude/clearance from a transmission tower while on an extended base leg of the traffic pattern."

      LATimes quoted- "Veteran fliers say pilots who have done their homework should be able to avoid [a tower like Fullerton]. "It's a potential threat, but if you study the charts and you go in, then it's a nonissue," said Bunck, 57. "We all stay clear of it.""

      NextGen will reduce the already manageable risk of CFIT even further, and enable very dense airspace usage, including AWES. Refer to Forum discussion of the old Hong Kong commercial jet approach for an understanding of how close competent piloting and obstacles is already proven to co-exist. 

      AWES professionals will strive to meet or exceed all FAA standards; initially requiring AWES PICs and VOs to perform sense-and-avoid operations (the AWE "crackpot angle" is to reject the FAA process and standards a priori).

In this case, a modern braided cable with suitable swivels would not have stored up torsion like this rig did, and some sort of aero surfaces on the hook or stretcher could damp away the spin.

      Subject: Service Animals in AWE
      While its not a major AWE topic, its not worth sourly dismissing a priori, that service animals have a definite place in aviation, including kites (the avi- prefix itself a clue). 

      An aviation starting list of direct and similar service-animal cases-

      -Cody used his Wild West show-horse to assist serious kite operations. .

      - A working dog at a kite field is not too absurd; after all, resident dogs are common at small airports, and many large airports have security dogs. 

      - Dogs can be trained to listen for roaming air-traffic, for enhanced sense-and-avoid capability (VOs are already trained to listen).

      -Hawks might serve varied roles in low-complexity AWE. Hawks are used at airports to scare off birds, and might be the best mitigation of birds perching, nesting, and soiling fancy kiteplanes sitting perched in calm. They might even actuate a fail-safe mechanism aloft (like landing on a baited-perch trigger-device).

      -Livestock were the the first Montgolfier Balloon passengers. Dogs and monkeys were first in space.

      -Pigeons relieved a German siege of Paris (microfilm was invented for the purpose)
       
      -Pigeons and monkeys were trained to operate early guided bombs. Computer and Systems Science built on this (as Cybernetics).

      -Bats were rigged with incendiary charges.

      - The Dog Stake was adopted for a new style of kite flying. kPower successfully tested dog-stake based AWES.

      -An old friend, Chuck Parker, flew his gerbil from a toy kite.

      - An Ilwaco fisherman had the imagination required to suggest a dog-launch kite-method. Modern service dogs serve in many niche roles, and the list only grows.

      Collecting my former notes and summarizing here for extension to others: 

      Portable Hang Glider Launch by Use of AWES Allowing Classical Running-Down-Incline-into-Wind Foot-Launching of a Human-Piloted Kite Hang Glider

      Portable "Mountain" Hang Glider Launch 

      Have kite-system AWES hold at desired altitude an arrangement that permits a free-flight pilot to run down an incline holding his or her wing into the wind to launch into free-flight gliding or soaring flight to fulfill classic launch style. There are many ways to embody the arrangement and execute getting wing and pilot to the launching arrangement.  Not limited to the following description here presented to example the system is one way: 
           Have a two-tether train AWES soil-or-rock anchored (or other means of anchoring); have the lofted launch pad use splinted-airbeam launch-incline format and have a horizontally-kept splinted-airbeam preamble assembly-ready deck or platform. Either have the wing already parked at the preamble deck or packed at the preamble deck aloft or use other procedures to get the wing to the preamble aloft deck. Once the portable "mountain" AWES is flying and conditions are "go", then the soon-to-be free-flight kite pilot climbs to the preamble deck, assembles the HG wing, hooks his free-flight kite tether to the wing, fulfills all checks, reads the wind, readies to run down the incline for launching into FFAWE mode off the portable "mountain."    
           Note that a paraglider is a canopy hang glider; and that a gliding parachute is a canopy hang glider. The system may be used repeatedly. Systems may be designed to hold more than one HG wing and more than one HG pilot. Also, the preamble deck may hold other things (napper, food, water, personal-relief devices, warmer, communications, weather-and-traffic station, and assisting equipment, or anything else reasonably wanted).     Note that the base kite-system AWES may be flygen generating electricity by use of RATs for various uses including the charging of batteries that may be fitted to the hang gliders for their on board electrical instruments which might include an auxiliary motor for in-flight conversion to powered flight, if wanted. There are many ways to design the preamble deck and launch incline to reduce drag and mass.  These portable "mountains" may be fixed at a park or club site; the system may be transported to desired sites on earth or a planet's surface; the system may be anchored to a ship or barge or other vehicle. Uses may be single-person dedicated or used in robust commercial operations.  The serving "train" of wings in the AWES may have one wing or many wings; also, kite trees and other gang arrangement of wings are intended in this instruction; also intended is the use of kite arches or other kite complexes for basing the preamble deck and launch incline. Anchoring reels and winches may be used, but are not necessary in all circumstances; one may use a reel-less AWES arrangement. System-stop methods are intended to meet safety standards. Personal rescue parachutes are recommended for persons going aloft for the subject operations. Skill training fit for the subject system is necessary to obtain safe operations.

      A new trick for tilting isosuperlattice kixels individually is to have each sail in embedded in an iso-mesh, but also individually bridled downward to a point (on a lower mesh or ground surface). As the wind displaces the upper mesh downwind the lower bridle-points are disposed to displace less (or not at all), and the downwind tilting bridles passively orient each kixels to have a suitably polarized AoA for lift (eigenstates). Previous methods involved active draw-lines in more complex rigs.

      Another isosuperlattice trick, less novel, but very overlooked, is to move lifter kites to the upwind side of the iso-mesh, to support the LE. A related detail is upwind bracing lines to the LE. This anyonic edge condition supports an entire mesh far downwind, for high overall spacial capacity-density.

      Subject: Kite-Farm Land Corridors for Multi-Use Landscapes
      A persistent problem in AWES design is how best to maximize land and airspace capacity-intensity. In particular, the low flying-angle of a loaded kite system requires a long tether to reach proportionally high altitude.  A very large kite-field was presumed to contain the scope of a single main tether anchored at the center. Moving the upwind anchor point to the edge of the field helped reduce land need, but not enough. If only a compact AWES dense-array could be made to tower directly over a small footprint, and always stay in bounds, then very little land would suffice for major AWE production.

      A simple design solution is a star geometry of radiating land corridors (to be aka "rays" or "runways") from a compact central field; three rays, at a minimum. A long tether from each star-point could operate on and over each ray, providing the upwind brace or side tagline function to the entire kite farm. Most of the space between the rays would be clear of any interference with kite operations. Cleared rays could have underpasses for road traffic, or even consist of elevated stands over multi-uses. Where possible, towers or terrain could hold landed radial lines tensioned over obstructions. Corridor status would apply to the limited areas where the lines might fall if broken (rare event), or the lines (100kg per 30m typical) could have soft-kite lift features to fall slowly in a failure, but ranging wider, but landing nominally only within narrow corridors.

      AWES Land Corridors have been discussed as a cross-country method. This post expands the pattern-language to kite-farms. Up to an order-of-magnitude improvement in land capacity-intensity is possible by this method.

      Make ice aloft in AWES by a variety of means. Send the ice to desired planet-surface points by having a reusable ice-berg encasement that has glider controls for homing to a target. The encasement is to be glider-shaped. Receivers are to save and recycle the shaped smart casings.

      ​===========================
      ​I am not sure what this instruction is about. 
      My guess is that when two ships are set to collide for failure of many systems, 
      then an emergency kite system could be shot out to air and maybe water
      and then winched in strongly to pull ship off its dangerous course. :: not sure. 
      The guess brought back memories of a human vertically self-lifting off 
      earth surface by shoot up a set of parachutes and then rapidly climbing
      the fall line.

      Many members may have read the paper; however, the paper has not
      been discussed openly in detail. The envisioned discussion duration
      could be months or years. 

      The paper's abstract was partly confusing to me, probably a result of an 
      oversimplification or just not enough room to clarify a method.

       DaveS wrote: " A new trick for tilting isosuperlattice kixels individually is to have each sail in embedded in an iso-mesh, but also individually bridled downward to a point (on a lower mesh or ground surface). As the wind displaces the upper mesh downwind the lower bridle-points are disposed to displace less (or not at all), and the downwind tilting bridles passively orient each kixels to have a suitably polarized AoA for lift (eigenstates)." This way seems promising.Please RodR can you make some video of it as a basis for some evolutive discussion? Perhaps by taking your recent youtubed isotropic realization as kixel for isolattice?

      Possible advantages of isotropic dome:both maximization of space and adaptability to wind changes without expensive and heavy device, only by legs.
