Wind-inflated domes. 
I covered various wind-inflated huge items in earlier years during the studies on inflated slopes, inflated inclines, artificial slope-soaring ram-air parafoil mounds. Pere Casellas participated in those early discussions. I am not yet sure of the dates on the A. Bolonkin's meditations on similar wind-inflated bubbles. 

Note that interior stay lines may bring relative flat mattressing; the stay lines would reduce membrane tensions that would build up to large when just one bubble is emplyed without the interior "cavexing" auxiliary lines. 

My "cavexity" terms are now three decades old; it speaks to lines that connect two distinct points in a bladder; the line dimples either the skin surface or dimples the skin surface in two places; if one end of a cavexor (line) anchors to earth and the other end anchors to the skin of an inflated bladder, then a dimpling is invited. Jalbert ram-air parafoil is essentially a wind-inflated domes with "cavexing" lines and interior cavexing walls as tensional ribs. Huge parafoil kites have used interior stay or shaping or cavexing lines.

Subject: Texas AWE Encampment Lesson (Sucker-Wind)
This has been a wind-poor spring here at the Encampment, mostly either stormy or calm, so this year's lessons include kite operations during downtime or sucker-wind. An ideal aspect of downtime is to build future AWES test capability and capacity in the shop. The case of sucker-wind is more ambiguous. "Sucker-wind" (as coined by classic kiting) is fitful marginal wind conditions when kites come down in lulls and must be constantly relaunched. The gentle but radical turbulence acts capriciously, and kites experience all sorts of minor glitches in sucker-winds. Sucker-wind is a critical test condition for AWES of all kinds, especially non-crashworthy designs.

As we continue to map standard physics to kites, in the sucker-wind cases, the interpretations of thermodynamics and chaos stand out. We see that zero-point energy, the minimal energy a kite requires to fly, is a delicate transition, and there is hardly any Gibbs's free energy available to do useful work, and the kite is at the edge of failure. The ground state of the kite ("grounded") and the nominal working state in a good breeze are relatively stable compared to the chaotic regime of a kite in sucker-wind.

Yesterday, kPower was flying a 2m2 Pansh parafoil with a PTO in sucker-wind. The kite was able sweep intermittently in ~5mph gusts, but lacked grunt to pump the load (a wheeled cart with bungee-return) consistently. Kite steering was easily stalled if the pilot snubbed up too sharply against the load. There was often a perceived need for a clutch or elastic effect to mix the load in smoothly, although its also clear that a trained pilot can mix in load force by skilled flying. The PTO itself tended to flop, braid, and jam during slack events, to be mitigated by design changes. Theory and practice agree; the major lesson is to avoid sucker-wind (except for testing and training), using the extra downtime to maintain and upgrade the AWES.

Subject: How optimizing general R&D in AWE

There are more projects in AWE than a few years ago. Some technical elements are common to the projects. So mutualization could be envisaged. Examples by methods:

  • Yoyo soft wing is studied by Enerkite, Windlift, e-kite, Tu Delft, Gipsa-lab, KiteGen, SkySails ....So a common project, for example in scale, is possible.
  • Flygen autogyro-like are studied by Sky Windpower and some other players...
  • Stationary groudgen: SuperTurbine, Daisy...
  • Carousels : NTS, KiteGen...

I think there's large similarity between the classes stationary groundgen and carousel. It's just cable routing or generator siting semantic & rotary radius.
Im quite keen to throw a YESTAM Thorough Air Mixer.. A below arch set contra rotary inner ring design into this space too.

Subject: Re: How optimizing general R&D in AWE

Yes for similarity between the classes stationary and carousel. But also (for me) a difference: in stationary groundgen (ST, Daisy, others) the single (eventually stacked) lightweight body rotates with the conversion system (shaft, torque ladder or other); and in carousel several lightweight bodies, being relatively smaller, fly more or less around (but also with by direct drive (NTS) or no (KiteGen)) the conversion system, by a more or less circular trajectory comprising a zone of depower, so out of a real stationary .

Subject: Statistical Mechanics views of AWE
AWES theory has by and large been framed by classical mechanics for crude contradictory first-order approximations, while engineering development mostly focused on early investment market revenue on short design cycles, with no clear winners. A few scholars, like Prof. Cristina Archer, ventured past the classical frontier into the bulk thermodynamics of global AWE [Springer 2013]. This is a vital upper level of AWES abstraction, if global crisis is real; to address deep engineering problems at every scale with the best-suited mathematical tools.

Meteorology is based on thermodynamic statistics, so Cristina had a great head-start. The theoretic frontier in current AWE is to develop statistical mechanical models based on kite farms as ensembles of sub-units, and hypothetical sets of all kite farms are complex ensembles in a sea of wind turbulence. There is no doubt about the power of statistical mechanics to drive AWES design in both economic and and engineering dimensions, but the topic is too big and new to encompass here; only a few examples can be given.

in 2011, KiteLab and WOW did a Critical Path analysis of peak AWE prototype power claims, showing exponential growth of both players and peak power values. We have lately begun to define AWES in terms of Planck units for kites, and can thus see theoretic global demand for AWE as "normalizing" to one, and many other new natural units (like kite and wind characteristic dimensions). We are starting to see topological statistics across varied kite-farm paradigms, which may offer disruptively useful "proofs" of which AWES architectures are favored for major study.

The AWE Statistical Mechanics frontier is so open that one need not start as a statistician to make progress; just study and apply the concepts in an interdisciplinary spirit-

Catching up misc ideas

- Vacuformed state of an AB Dome to its surface medium; for example, ahead of  a storm event, the dome is brought down by negative pressure and secured from rooftops and towers. Vents opened on the downwind side can draw air out. Tag/Droplines can align the membrane to fixed supports.

- AB Dome Islands created by the air bubble of a partly sunk dome. A massive city could occupy the inflated surface, according to hydrostatic pressure developed within a deep skirt.

- AB Domes can be floated cross-country, if designed for solar-thermal ballooning mode.

* Note to Rod, regarding the nature of Open-AWE IP as a "Cloud" where all the varied old aliases (CC+, FairIP, CoolIP, etc.), along with the growing AWES Patent Pool) comprise the Open-AWE_IP-Cloud. Thus the AB Dome patent has been licensed via kPower into the cloud, and the CC+ elaborations are also entering the Open-AWE_IP-Cloud here. The IP-CLoud is now a practical working model, with Aerotecture IP as a prime case. Anyone is open to join with the creators, on proven cooperative principles, without the standard barriers-to-entry that "hard" IP presents.

As predicted here, GoogleX's M600 is apparently as dependent on its massive capital intensive cradle-tower as comparable conventional wind turbines are on their towers. The M600 tower is also far more complex, with scant basis to claim that this High Complexity AWES architecture is in effect just the tip-of-the-old-turbine, as has been often asserted. Makani's website now only claims that the

Subject: M600 Hawaii testing on hold

Just last week Makani finally admitted that the M600 is far from scheduled readiness and that Hawaiian wilderness is not the ideal choice for debugging a large complex aerospace platform, regardless of GoogleX's venture-capital bonfire capability. So Makani is staying on the mainland for now. A ~100m gin pole has been set up over an M600 cradle-tower. The roar of motor-hover testing will be audible to our local observer network embedded in the semi-suburban Alameda airbase. It can be presumed that the M600 must launch, hover, and land reliably on its short leash, or maybe never fly Hawaiian sky. Each increment towards aerobatic operating mode is a leap in engineering drama. 

In Google's anonymously familiar words-

"..we can’t wait to see our new energy kite fully in action, we’re going to start off slowly by testing things incrementally. We need to get to know our energy kite first, and have it complete individual tasks successfully before giving it more advanced tasks. This means repeatedly performing functions as basic as powering the kite’s motors on and off, or getting the kite to hover with shorter tethers before we use a full-length tether. By testing close to our Alameda headquarters, our team will be able to quickly solve any issues that come up. Our engineers and scientists may even end up rapidly redesigning and rebuilding components as needed to ensure we have the best energy kite possible before we head off to Hawaii for our pilot project."

Makani makes a reasonable claim that offshore operations might resolve land and space concerns. This is far less in doubt than whether its massive surface machinery can be claimed to eliminate the wind tower.

Subject: kPower flys 132m2 IsoDome Lattice at Texas AWE Encampment
Yesterday, on Mustang Island north of Corpus Christi, Texas, kPower flew six 22m2 PL Pilot-Lifter kites arranged within three anchors set in a large triangle. The kites flew well close together, tolerating large sudden wind direction variations (~150 deg.), in mesoscale turbulence around local rain showers, providing further validation for iso- kite structure.. 

The day before had been the "worst session ever", arriving late, hastily digging anchors, and improperly rigging a two kite stack in high wind for a rich lesson of new and forgotten errors to avoid. Regrouping the next day, we worked back into the sky, and met our technical goal, with radically improved technique. 

This maiden flight test was in the FAA Corpus-Christi UAS test range, under legacy kite rules, but at low altitude (~100ft) intially, with testing "long-line" to 2000ft planned for the Warm Springs, Oregon, test range, and a public appearance at WSIKF2015. Thanks to A-Bomb, a local kite-surfer pro, for assisting. Ed will post photos next.

Land and space use is a major concern, onshore and  offshore, due to the high cost of electric cable, due to preventing any secondary use (fishing, travelling, others) on a far bigger zone than for conventional wind turbines. So the maximization of space is required.

I remade my old lift kite controller. It now has a wee electronic autopilot.

Previously remote controlled, it now uses an IMU chip to detect kite roll angle.
Roll is the most common flaw on my SSSL lift kites. A micro-controller converts roll to correct steering with the servo yacht steering horn.

      Rod,

      Beautiful wings! Open-AWE has discovered a huge resource in the form of old sails available at bargain prices.

      As KiteLab long ago envisioned, kPower has been planning to fly COTS used sails for years, but you beat us to it, since we worked instead on tarps, as the sleaziest option. We still plan on testing symmetrical spinnakers from socks (Ed has a purchase order in process) as a furling means, and asymmetric spinnakers (gennakers, etc.) more or less as you rigged. One can buy maxi-yacht sails ratable in MW for a few thousand USD.

      By-the-way, note that KiteGen's new wing is kixel-based, a basis to claim AWE IP Cloud priority from SABIC,

      The M600 is simply not the most relevant case to single out here.

        I housed the control and battery.
        Then found a suitable rod for mounting the roll sensor on between the outer bridle lines. .
        Instead of my sssl lifter I decided to use my older sled lift kite (this meant reversing the controls... So I tied the sensor on the other way around)
        With the controller turned off, the kite was very unstable on the ground.
        I turned on the controller and was able to walk back upwind on the tether while the kite stayed going up straight... So far so good.
        A big swoop was recovered.
        Then it all seemed to be quite stable and high... But upon recovery I discovered that the power line had snapped... Drat!

        Indeed a train of kites is a mean to balancing tether length and kite global area. Another mean is increasing the size of a single kite.

          A surprise participant at AWEC2015 is Gordon Planes, Chief of the T’Sou-Ke First Nation in BC Canada, indicating another Pacific NW tribe is moving into AWE (maybe the Ampyx kite farm partner hinted at). This adds a forth First-Nations tribe to the list of AWE players. Not far south are the Confederated Tribes of Warm Springs; the Wasco, Tenino (Warm Springs), and Paiute, whose OR USA reservation has been designated as an FAA UAS Test Range (with kPower planning provisional AWES testing and training this summer, esp. for exploring wildfire fighting by means of kites). 

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

          First Nations have lived for thousands of years on this continent without fossil fuels. It is appropriate that First Nations lead the way out of dependency and addiction to fossil fuels and to rely on the power of the elements, the sun, the wind and the sea once again.  -Chief Gordon Planes.

          Yes, Pierre. 
                Additionally: lateral sets of trains coupled. 
          Then further: downwind  repeat rows of such trains coupled; and couple the rows at up-going stations. Presto: 3-D matrix.  Set such all on dome mesh as base, having ground anchors as needed. Then fly the multiple-coupled domes during calm by smart cross-wind towing oscillations.  kPower has recently shown a start  in this direction as posted this week on forum.

          Indeed passive stability is assured by the central line with hangers which provide reference angle of attack while conversion is assured by peripheral lines on the four (or more) winches.

          As the kite is tilted while the ring is horizontal there are cyclic variations of peripheral lines lengths: on video one can see there by the variable levels of white marks.

          Generators are rather settled in winches: so there are both reeling by winches and rotating by ring. Generators can also be settled between the rotating part (rotor) of ring and the fixed part (stator) of ring.

          And we can expect that scalable soft-kite versions can be built, including the Daisy concept driving the same Rotating Reeling carousel.

          This seems like a major advance, with all the elements coming together.

          One can see soft kite (parachute + two ram) in the beginning of the video. But their proportions are not good enough to allow easy rotation with ring. Morever Rotating Reeling is rather for big unities where rpm is very low, reeling from winches assuring conversion on the side of kite going upwind by rising. I think good proportions are 1/3 parachute diameter and 2 times 1/3 for wings.

          So in scale soft kite is prefered by far, but for demonstration on small system rigid blades are easier although not quite satisfying as is, their torque being not quite adapted to the work.

          Indeed rotating kites denoted Parotor for Rotating Reeling could work as Daisy and vice versa. An option is also a train of Parotor working in gap as a sort of ladder torque, the first Parotor working by Rotating Reeling, but (at least now) I prefer a single bigger wing for easier operation. 

          However my opinion is working on parachute as hub to keep some lift in spite of rotation.

          Probably an active cyclic control must be add in passive control, also for launching and recovery.

          The ring as part of conversion system works also as multi anchors (winches) allowing safer operation of a giant kite. The similar diameter of both ring and canopy should facilitate launching and recovery.
