Subject: Pulley-Loop Moon Elevator Tether Model
Planetary space-tether studies offer new thinking about long-tethered tech. Note "characteristic height" nomenclature for a polymer's vertical length capacity in a given gravity-well, as used in Wikipedia-

"The study done for NASA's Institute of Advanced Concepts states "Current composites have characteristic heights of a few hundred kilometers, which would require taper ratios of about 6 for Mars, 4 for the Moon, and about 6000 for the Earth. The mass of the Moon is small enough that a uniform cross-section lunar space elevator could be constructed, without any taper at all."[1] A uniform cross-section could make it possible for a lunar space elevator to be built in a double-tether pulley configuration. This configuration would greatly simplify repairs of a space elevator compared to a tapered elevator configuration. However a pulley configuration would require a strut at the counterweight hundreds of kilometers long to separate the up-tether from the down-tether and keep them from tangling. A pulley configuration might also allow the system capacity to be gradually expanded by stitching new tether material on at the Lagrange point as the tether rotated."

    Long Kite Systems
    This topic thread invites focus on long kite systems that may be the basis for doing practical works.
    Designs, reports, discussions, experiments, challenges, etc. : all invited.

    This topic goes beyond "long" in the "high-altitude" sense, but does not exclude such matter.

    Also, this topic goes beyond the recreational "long tail" display, but does not exclude such matter. Indeed, explore long tails for practical works.

    And this topic goes beyond have a kited wing dragging out across oceans or land one long tether, but does not exclude such systems.  Explore practical uses of long systems in this category.

    This topic enfolds long system laundry or auxiliary long constructs when a vision of practical works may accompany the attention.

    We have visions already expressed of a long kite system that might be flown to encircle the earth; practical works for such are invited to be expressed.

    Recall that a single kite system may have a multitude of tethers, anchors, wings; the count of members may go extremely high. And keep open that any "anchor" may be a "wing" itself. And note that a mix of materials may form any element of a kite system. A kite system may have parts that are also considered payload or instrument. Parts may be alive (virus, bacteria, plant, animal, human). Parts may move in various ways. Recall that a kite balloon is still a kite. See that rigidity of parts may vary over a broad spectrum from limp to brittle.

    The practical works of long kite systems may be one or many in various combinations.  Not all parts or works need to be active at any instant of a kite system's operation.

    A decade ago approx. we saw the feasibility of a great-circle kite holding many wings and many down-to-earth tethers; my graphic won the Santos "feasible" remark.   Well, herenow an extension of such direction: Grand Helical Earth Kite (GHEK) : Perhaps have a start or turning point of loop at the north pole and similar at the south pole; then wrap the wing-upper-line set around the hearth helically so that at any longitude one finds hundreds or thousands of crossings of the single kite. Perhaps millions of wings in the kite and millions of down-tethers. Essentially one anchor body: earth!

    Subject: Geo-engineering Atmospheric Rivers?
    "Atmospheric Rivers" of moisture in the sky are one of the largest, most powerful, and ubiquitous meteorological events, with both destructive and life-giving effects on an intercontinental scale; but the term itself is barely twenty years old, as improving satellite data starkly revealed them. They are a major Planetary mechanism of heat-transport to Northern Latitudes, so they might figure in combating climate change, where the North is most vulnerable to key catastrophic effects (like massive methane release).

    Megascale kite formations are currently the most plausible geo-engineering means to channel and tap atmospheric energy and water transport. In principle, a barrage of kites can act like a mountain range to divert flow to break droughts or prevent flooding. While bulk influence is still a distant prospect, today's kites could already ride the consistent upward convection of these rivers over long distances, with large cargos, or create strong local weather effects, like reduced or augmented precipitation. Atmospheric Rivers are a more consistent basis for such intervention than spotty local storms.

    Many potential kite apps are periodic and opportunistic, where the kites await design conditions in storage, act briefly, then return to storage or get recycled. This is a different life-cycle basis than "common" AWES, where years of extended duty is desired.

    Subject: Passive-control reversal of a diving delta kite explained
    The common delta SLK (single-line kite) is an impressive flyer; able to fly at a higher angle than any other classic type. In smooth wind, a steady delta is said to be "pasted to the sky", and it also copes with turbulence fairly well. Nevertheless, a delta kite is eventually subject to a gust sufficient to tip it sideways, and either it loops harmlessly by the angular momentum created by the upset, or it locks into a "death dive" and crashes. This can seem very mysterious, given the invisible forces in play, but the following basic explanation accounts for most mishaps.

    A delta depends on a bit of pendulum-mass to fly oriented nose pointing-up, as seen form the ground. If the kite is yawed strongly enough, the embedded pendulum becomes an "inverted pendulum", which is normally unstable, but its known that a forcing vibration can damp and stabilize an inverted pendulum. Two dynamic stability features of the delta apparently provide such vibration; the "snow-plow stability" feature pushes back on the advancing side, and the "stability flapper" pulls back on the advancing side. The inverted delta yaw-oscillates as the angular momentum flip-flops. A delta's keel also deepens in a gust (just like a fighter kite), further locking-in a dive.

    Given such passive-control reversal, the alert flyer quickly pays out line so the slackened delta kite recovers as a glider, then takes back line to recover nominal state. By skilled flying, the delta becomes extremely reliable. Other solutions include setting a slight turn into the kite's geometry that prevents locking on the dive; trading away some normal stability to destabilize the dive, but the kite will tend to loop more than before. Another approach is a small damped reaction mass to inputs a steering force when the kite inverts.

    There still remains a rare structured turbulence that in effect expertly pilots any SLK into a death dive, despite the cleverest control design or most skilled human pilot. When such failure is not acceptable (by "high-consequence"), the remaining design tool is to cross-link enough kites aloft (multi-lined), to cancel out isolated instabilities by "aggregate stability", to the required reliability factor.

    Thanks to Kelly "Sky" Reed for this kite-tech kite-culture inside scoop. Sky started in Austin with Joel Sholtz and New Tech kites a generation ago, worked on pioneering Quadrifoil traction kites, won KTAI's best-new-kite-award-1998, and in recent years has been with Marc Ricketts's GuildWorks. Sky recently trained Cirque du Soleil performers in indoor kite flying, with the "Toruk- the First Flight" (Avatar) production intending to fully develop flying elements.

    What does "show news" have to do with AWE? Its a KiteLab Group prediction that AWE will emerge from the "right-stuff" collective genius of the "kite gods", the small world of elite kite designers and flyers, as well as elite aerospace talent; working together. Sky is one of the tribe-

    The popular Christmas song, "Do You Hear What I Hear?" is yet another major cultural instance of the kite-trope in its characteristically yearning salvational context, including a quasi-apocalyptic Cuban Missile Crisis origin back-story. The instant-classic song's lead author, actually named Noel, was formerly a daring double agent in WWII, according with Twain's axiom that "truth is stranger than fiction". Noel's specific personification of the Night Wind seems to originate with Emily Bronte*-

    Said the night wind to the little lamb,
    "Do you see what I see?
    Way up in the sky, little lamb,
    Do you see what I see?
    A star, a star, dancing in the night
    With a tail as big as a kite,
    With a tail as big as a kite."

    Right now is the most dramatic time ever in AWE, as Makani prepares to launch its monumental M600 AWES in Hawaii; and the news will be spectacular, good or bad. Therefore, Doug rightly observes that the biggest AWE news of the moment is purely speculative.

    JoeF,

    There really is more AWE news than ever, but it naturally comes in bursts, so an impatient bystander can easily misread the trends.

    The latest trend is for more teams to raise major investment (like Altaeros gaining Mitsubishi support), but this new bigger round of R&D funding now has to work its way onto the test fields. A prime example is Bill Gates' open endorsement of AWE as a clean-energy "miracle" possibility, and his newly stated intent to invest many millions in foundational R&D.

    Doug has no better option than to wait confidently for expanded testing news on its own engineering-driven schedule, rather than wrongly reason from personal impatience. As AWE news continues, he can count on us to share it promptly, without needing to ask plaintively. If he has any ST news, now is a good time to be noticed, in relative calm,

    Subject: Re: Spiralairfoil
    Congratulations to Dan'l for strong academic engineering validation of the specific advantages of his Spiralairfoil high-solidity rotor, with far less parts than the classic Aermotor HAWT; as originally proposed on the AWES Forum. Dan'l's design is optimal in most-probable low-wind situations for high-torque work; not to be confused with conventional HAWTs on towers in prime high-wind locations, where a heavily-built high-speed low-solidity rotor is the appropriate solution.

    The extremely low start-up wind velocity (0.85ms) and usable low-wind torque are now proven by third-party research, but the huge theoretic advantage for AWES use is that a low start-up wind velocity equates with a lowered sink-rate in flight, compared to ordinary HAWT rotor geometry, a trend seen in rotor-kites. Other likely advantages include Spiralsirfoil soft-kite variants with greater safety, scalability, and lower capital-cost.

The method exploits the arch-stabilty principle inherent in the spread of a kite bar, which is known as "auto-zenith" in Peter Lynn's parlance (I recall how amused Peter was years-ago, when I initially guessed that auto-zenith was mainly due to a feedback mechanism in the wingtips of his power-kites).

    The auto-zenith state becomes progressively unstable as wind velocity rises and/or the spread ratio between the wingspan and barspan increases. Dutch-Roll oscillation grows from infinitesmal to large figure-of-eight sweep patterns. I had experienced this tuning parameter many times, but yesterday, in gale-force winds, flying a NTK 1.2 foil on a small bar, I dared to just close my eyes and hold the bar tight in a fixed position. To my amazement, the kite flew about 5 minutes in wild sweeping eights, but never crashed. Had it crashed, the foil would have tended to self- re-launch, as has been observed countless times.

    Either flygen or groundgen PTOs can be applied. The "crosswind kite" performance can be enhanced by a valved parafoil, since the open-celled foil occasionally collapsed in violent turbulence (yet always recovered before crashing, in the session). The ratio of wingspan to barspan was fixed at 4-to-1, but would be adjusted to large changes in wind velocity. This wingspan/barspan ratio is a new dimensionless number unique to power kites. A time lapse video with statistical analysis should make a nice study.

    Subject: Iso-SS Power Wing Concept
    A new kind of single-skin (SS) power wing is proposed, as a radially symmetrical ("iso-") thin-wing suited to sweep about in its kite-window, without orienting about its y-axis. Such wings could take the plan-form of simple polygons or circular discs, with ring-and-slot/apex-hole variations. A kite-tech similarity model is Sedgewick's flat iso- UFO kite (but with a hoop frame).  A biomimetic similarity model is a flat cap of a gilled mushroom; the gills suggesting a fabric "dart" (rib) layout. Ideal forms might resemble a throwing disc or ring, but be SS soft-kites.

    SS kites are supremely scalable, with the highest power-to-mass potential. Conventional decellerator construction is already shown practical to mega-scale [US Military, NASA, etc.], but previous designs counted on deep chord sections for maximum stability. NPW, OL, and PLSS power kites emerged, by are aniso- rather than iso- designs. Like these SS power kites, the new Iso-wing would have its risers and fabric ribs impose a thin flat (planar) geometry, for high L/D sweeping crosswind semi-chaotically at high velocity, theoretically developing high power in AWES use. Iso-kites solve the problem that a,  kite-farm scale aniso-kite-structure is slow and difficult to rotate, compared to merely tilting an iso-structure.

    Ordered motion would be imposed by a secondary PTO bridle lines, possibly even radiating in-plane from the disc; to both tap power and provide control actuation. Its proposed that large cross-linked lattices of such wings can be engineered to semi-passively self-synchronize, for naturally coherent high-Q output. Lattices could include lifter-kites on tri-swivels along guy-lines. PTO design options range from a network of vertical pumping lines to a surface workcell network, to tapping bulk lateral motion of the kite lattice at an outer anchor/PTO circle.

    The ROPOS deep-sea ROV is capable of complex operations to 5km deep at the end of a mutli-modal tether (lift, power, and comm), with many features directly applicable to airborne tethered systems.

    ChrisV is on the right trail. Floquet Theory leads to Block Waves, the best mathematical representation for phonons in a quasi-crystaline kite-lattice [kPower kite-matter lattice-wave designs]. Bloch waves easily seen in the oscillations of dense kite trains (periodic kite units), or even in the billows of a flapping flag (fabric weave as the periodic structure)-

    Christof,

    Thank you too, for all your do. It seemed your Challenge rules blocked kPower's best methods- "any AWE method that has not yet been used to do [more-or-less] the same"; and kPower already had many great cameras, including GoPros.

    AWE is generally a grand challenge, and you may recall how US DOE toyed with a prize challenge a few years ago. Consider framing a AWE Grand Challenge plan with a year or two time-frame, for all major players to measure up to. A large prize could be raised by social media, even after the challenge is won. The criteria would need to be more like a scoring matrix, cross-simulation, and fly-off format with an expert judging committee.

     Re: joining someAWE.org, I heartily recommend it, and even propose that the creaky Yahoo AWES Forum migrate en masse to someAWE. Its just so busy keeping up with an accelerating AWE R&D dynamic (the public record is just the iceberg tip), that many details are lagging...

    We are witnessing a relentless trend in kite patents, with Luo and Qui's patent as representative, where the AWE patent-thicket only continues to thicken, as a flush of new overlapping patents cite each other (even patent examiners piling on easy-searched citations, despite a general demise of close PTO review). There is a paradoxical effect on IP certainty, as more and more claimants enter the fray. In theory these patents are protecting something of value, but no one can say just what, lacking settled litigation. No patentee can dominate, especially as so much key kite art is so old, and its hard to see that any AWE patent has a strong claim to any essential art that cannot be worked around.

    Nevertheless, AWE patent IP remains an abstract statistical force, with amorphous advantage to whoever controls the most patent IP. KiteGen, Makani, and the Open-AWE_IP-Cloud are three of the largest collections of AWE patents, but the general effect is a stalemate, without any court challenges looming. The Open-AWE_IP-Cloud has the best momentum to outgrow all inside patent pools in AWE, and its intent to offer dirt-cheap licensing will be attractive to adopters. If you are holding an AWE patent, joining the Open-AWE_IP-Cloud early will provide an edge in sharing royalties over later members. kPower/KiteLab-Group is the umbrella-org for the IP Cloud, but its intended to evolve into a self-governed cooperative of the IP holders.

    Luo and Qui (and any other AWE patentee reading this) are openly invited to join the Open-AWE IP movement., which also pools all other forms of IP, including design copyrights, trademarks, and new "CC" variants. All you have to do is state non-exclusive intent to be part of the Cloud licensing scheme,  in writing, either to Ed Sapir (kPower), or in some public auditable channel. Early joiners have already started earning an early trickle of revenue, which will only grow as developers seek greater IP certainty at low cost.

    Notes:

    1) The Open-AWE_IP-Cloud proposes to compensate any creative contributor (or their assigns) to AWE art, at the discretion of the governing members, regardless of formal IP status. Wayne German is an example of such a contributor.

    2) Gaylord Olsen (whose patents are as strong as any others still unexpired) was the original Open-AWE_IP-Cloud (aka "AWE IP Pool") joiner, but we have not heard from him in the last few years, so his royalty payments are held in trust)

    Subject: GoogleX-Makani renews its long-term lease on Alameda Island (San Jos
    Its been ten years since Makani was founded and located at the former naval base on Alameda Island on the San Francisco Bay. By small coincidence, the Google Alert for Makani's lease came in my inbox next to the Changing Gears community bike shop ten years celebration announcement. Changing Gears is a close neighbor to Makani; both gained access to the base in 2006, and I was privileged to be present in early 2007, and frequented both sites during my happy time at KiteShip, also on Alameda Island.

    This renewed Makani lease, with options to "expand", suggests we have another ten years of interesting AWE developments, building on whatever lessons M600 flight-testing is about to teach, which may finally prompt Makani to explore wider conceptual directions (the lease is also a prerequisite for GoogleX to sell-off Makani, as Google does when it divests from fizzled R&D). A lot depends on the sheer luck the M600 experiences, and how Google chooses to interpret it (marginal performance can be hyped easier than crashing spectacularly).

    Lets hope Google only chooses to expand and diversify its AWE R&D, even if the M600 is proven in testing to have been an unsound AWES architectural down-select; to compliment the conceptual directions explored by other major investors like Gates, SABIC, and the EU. The next ten years of AWE R&D promise to be very exciting, with no overall shortage of capital, if not ideas.

    This record was limited to line available on the reel, so its no absolute indication of how high the kite could reach on that day, but there seems to exist a scale-ceiling around 5km high across the varied attempts. The authentic rough-'n-ready Australian Outback DIY construction of the custom hardware is an instructive contrast to the overly-fancy hardware many well-funded but inexperienced AWE teams contract-out, to less effect. The homemade delta kite seen here was almost pathetically prosaic, with the ugliest practical tail, but a delta is the right high-altitude kite type, and the homespun rig also counted on UHMWPE line and carbon spars for essential high performance.

    The multiple-kite (kite-train) official absolute altitude record remains the "Mt Everest" of kite records that has stood over a century, and requires a more complex rig of graded lines and kites to go far higher. Rae Bohn, Dave Colbert, and I have discussed how this record might be done by laying out the rig on our 23 mile US NW beach (not during tourist season) or paying out line from a moving vehicle and "walking" line down by vehicle as well. If anyone reading this wants to go-for-it with us (especially to fund the line and instrumentation required) let us know, we already have suitable kites, and we'll move the project up.

        From the German tradition of top LTA excellence, JoeF shares a very sound LTA AWES open-source concept to contrast with Altaeros' BAT. Two great advantages are evident- the envelope is a simple low-drag high-volume "albacore" form, as is standard in aerostats, and the girdle of wind turbines are an array of small units, avoiding the worst parasitic mass impact of square-cube scaling law for a single large turbine unit of the same power. This LTA-AWES variant, as presented today on the Forum, prompts a reworking of Oberth et al's LTA AWES concept as a COTS aerostat with a train of small HAWTS on the tether (or a pendant), rather than just one large unit of equal power, but a poorer mass-to-power ratio (Open-AWE_IP-Cloud).

        An open question is whether Altaeros, flush with early investment cash, will migrate toward the legacy LTA AWES open-source engineering, or risk open-source competitors emerging to out-compete on raw cost and performance (?) This message if Cc:ed to Altaeros in the hope they will explain the BAT design disconnect with historic LTA AWES concepts, either as a temporary stepping stone to the open-source German-etc. proposed ideal, or finally explain the Altaeros BAT as an inherently superior LTA AWES architecture, with a specific engineering rationale that generations of previous LTA experts somehow overlooked. Thanks to the company for any helpful answers.

        This LTA AWES concept represents an admirable but flawed early approximation superseded by later designs. Major disadvantages evident include the full-length external truss, were a simple string bridle should suffice, and the large complex structure and machinery located inside the ideal lifting volume.
