    Cuba and AWE?

    Francis told his companions to "wait for me while I go to preach to my sisters the birds." The birds surrounded him, intrigued by the power of his voice, and not one of them flew away. He is often portrayed with a bird, typically in his hand.

    Cuba has a very long coastline/area ratio.   What ratio of Cuba's energy will one day come from AWES (air or water energy kite systems) ?

    Subject: Automated Launching-Stick and Landing Tagline (for Mothra-Arches and
    Easy Mortha launching and landing was first validated by use of a manual Launching-Stick and Tagline. The central nose is tipped up into the wind with a forked stick (Ortiz Sr.), then whole wing inflates and launches. To land, the tagline to the nose is pulled downward at low force; the nose then tips down, so the whole wing lands.

    This effective method is simply automated by locating a tag-line winch at the Mothra anchor-circle center-point and a stub-mast "launching-stick" (fixed or retractable), to hold the nose up for launch.  Thus the large kite-farm arch can be launched and landed repeatably without manual interaction, either autonomously, or by pilot-command. A kite isodome LE could also be controlled similarly (by a different siteplan). Other variations include a launching stick and winch on the flying kite side of the system.

    An unloaded arch can launch early and reach good wind, and only then are WECS hauled up on halyards, for nominal operation. In lulls, the WECS come down before the arch, which may continue flying unloaded until usable wind returns.

      Portable Mountain by AWE (PMbA)

             Could someone use a mountain here or there? Hill? Slope? Ridge? Cliff? High place? 

      Let "mountain" embrace the cousins: hill, slope, ridge, cliff, bump, high structure, tower, skyscraper,... in this PMbA world of AWE exploration. 

      Some portable mountains may be supplied by working kite systems (an AWES category).

      How might one use a portable mountain, hill, slope, ridge,cliff, bump, tower, or high place? How are mountains and hills and slopes used?  Mountains have exteriors and interiors.  Mountains affect the environment in various ways. Mountains change, shake, erode, sometimes grow larger and taller, sometimes crumble.  A comprehensive appreciation of assets of mountains may move visionaries, designers, engineers, and builders to advance PMbA.

      Study and discussion on the PMbA realm are invited in this topic thread.   We have already touched upon PMbA some in various ways; linking what has been done could be part of the flow in this topic. Evolving novel PMbA solutions to serve the good of life on earth and other planets has a home here.

      Start:

      Mountain as an archetype seems to be something up high with lowlands near. Mountains have various shapes and characters. Access to the parts of mountains varies. Dynamics of mountain formation may tease AWE visionaries to methods of forming some PM-by-AWE (PMbA). Mass forming mountains have potential energy; when some of the mass in mountains move downward, then there are pockets of kinetic energy. Mountains provide overlooks, vistas, views; there are sides to mountains.  Mountains may be a base for further action or a destination.

        As megascale kite lattices emerged over years of AWES Forum discussion*, quasi-mountain qualities became evident. "Kite matter" structure can match or even exceed mountain-scale and create local climate effects. Kite matter can blend-in to the sky or landscape by camouflage coloring, or even be designed to look like a real mountain. It can form ghostly mountains of sparse sail-spacing, almost invisible, yet with a spatial presence of a mountain. They can look like anything, with lighting effects to boot. The common poster vision of a castle on an uprooted flying mountain could be created in real life.

        Kite mountains are hollow, of course, and would feel like vast cathedrals from within. Living around megascale kite farm lattices might be like living near mountains, but these are almost living mountains, more like giant monsters even, so there would be a scary vibe in bad conditions. But we intend to create friendly monsters, from the start. Kite Cloud, kite mountain; both express the basic idea, but Tomas Mann may have named it best: "Magic Mountain". Kite magic is real, and we are the student wizards.

        * I recall some years ago how RobertC boggled at the idea of a megakite the size of Table Mountain (S. Africa), when the key enabling soft-kite construction concept was found, of many-km rope loadpaths, with sails (in "kixel" arrays) hanked on.

        --------------------- tech note ---------------------

        JoeF rightly notes these mountains can move, perhaps travelling the globe like clouds. A kite cloud could work by complex DSing of local lattice units against remote units across internal flow shear, creating net-lift and propulsion. A spider-mill opposed by another spider-mill in FFAWE mode would have a cloud-like character.

          Subject: Multiple Crosswind Track AWES
          Multiple crosswind tracks (rails, roads, water, or cableway) can modulate a moving constellation of anchor points such that a large kite (array) can be tacked back-and-forth in a maximally stable "staked-out" configuration. Multiple tracks scale beyond a single-track unit limit. 

          Previous AWES concepts for single crosswind tracks require a smaller less-stable kite-unit to be more actively controlled. The single-track scaling-limit is its unit-limit. 

          Multiple free-ranging anchor-vehicles tracking in parallel is an obvious solution to adapting crosswind travel to veering wind (incl. XC transport), but cableways and rails can also be designed to switch crosswind paths, for better PTO performance.

          Rick Masters found a study that adds to the story of kiting spiders (most often "ballooning spiders"). The study suggests some lift from electrostatic forces.    Click through to Rick's note.     Interesting addition to kiting!  

          I am not sure yet about the matter; I like the spread of element silks by electrostatic action; such would give more exposure to thermal updrafts to the gang of silks.    

                We have FFAWE for the kiting spiders, but I don't think we covered the possible spread of element silks by electrostatic forces.

            Perhaps the best LTA AWES yet; Piero's flygen-kytoon integrates some top principles, but does not solve inherent kytoon and flygen trade-offs. As a kytoon, it has a nice potential to sweep in low winds by steering with its forward and aft wings, to then develop higher power in low wind. The LTA envelope becomes drag-limiting at higher speeds. The contra-rotating WECS turbine adds stability by aft placement, reducing the need for empennage vanes. This design could easily outperform a BAT, if a side by side comparison were made, but the Open-AWE option of using a COTS aerostat, to suspend a modular HAWT, is still favored by core criteria. 

            The problems in the high-performance LTA design-space are mass-driven. Its hard to provide the stiffness desired at hard-points on the hull surface, especially wing-roots, without excess mass. Rigid wings scale even worse in LTA regimes. Compounding the complexities of gas containment, and the high base cost of lifting gas operations, the resulting delicate designs are beautiful but uneconomic (unless some breakthrough in airframe construction is found). This is also a flygen concept, as such currently relegated to small or remote niches. Powering the planet with flygen-kytoons is simply unworkable; the main action will be in scalable Low-Complexity AWES concept spaces.

            Doug Selsam of http://www.selsam.com/ wrote:            Nice post on the electrostatic balloon spider webs. 
            I had an experience when I was 5 years old that changed my life. It explains why I know there are simple things that degreed scientists are clueless about: I was 5 years old in upstate NY, slept outside in a tent with a neighbor kid. We woke up before the sun and went out to play. As the sun was rising, we started seeing shimmering blobs slowly falling from the sky, changing colors as they fell. We tried to catch them but they disappeared like a bubble popping the moment our fingers touched them. They also disappeared when they hit the wet grass blades, but we noticed a very thin spider-webby substance left strung between the grass blades. The spider-webby stuff in the grass blades disappeared in your fingers if you tried to collect it. Many years later I contacted the other kid and he remembered it like yesterday.

            Of course we told my parents what we had seen and of course as we already knew, they didn't believe it. What adult is going to believe a 5-year-old telling them about shimmering colored blobs falling from the sky that disappear when you touch them? 

            Nobody could explain what we had seen. That was my entry into realizing that I knew things that nobody else knew, and at 5 years old had already experienced something that no scientist could explain. I realized I could probably figure out things that nobody else could.

            As the years went by I arrived at an explanation: Balloon spider silk in the still morning air was collecting condensation and falling from the water drops' weight, As the strands fell they formed mats, spread apart by electrostaticforce. By the time we saw the mats of silk near the ground, the sun was making rainbows through the drops, which we interpreted as the blobs changing color as they changed position relative to our eyes.

            When we touched the blobs, they disappeared like bubbles popping, because we disturbed their electrostatic equilibrium, draining the charge - the wet strands stopped mutually repelling. The blobs collapsed and seemed to vanish.

            And of course when they hit the grass blades, they also vanished as the electrostatic charge was instantly drained, but we were able to see the super-fine threads because they still had micro-water-drops on them. But the webs themselves were so ephemeral that they seemed to disappear as we rubbed the water drops away.

            I have since read about this phenomena several times. One account was in the same area, across Lake Ontario in Canada, in the same year, by a ship's captain. Same exact story down to every detail, except no grass blades on the ship.

            Other similar stories include single giant purple blobs that fall in yards, made of a substance that disappears when touched. The characteristic they all have in common is they disappear in your hands when you try to collect samples, or evaporate from jars if any substance is collected. The overall name for the phenomenon is "Angel Hair" and in many accounts it is related to UFO sightings. Often, people see a UFO spewing silk strands out the back and they fall as anger hair, which disappears when touched. There seem to be a lot of these UFO/angel-hair accounts in Australia. The night before, we were convinced a UFO was watching us (watching too much TV) and I am puzzled to this day that most accounts of this angel hair phenomenon relate to UFO's and seldom mention the idea of spiders.

            Anyway, when I saw the story of exactly what had happened to me in a book of "unexplained phenomenae" I realized that if I knew this one particular "unexplainable" phenomenon was real, maybe a lot of other weird stories off such phenomenae were also real, so I never laugh at any account of something unexplained, no matter how improbable it sounds. I know how it is to have something unexplainable happen and nobody believes you. But in my case, I think the spider explanation works, and some other witnesses and scientists have also applied a spider silk explanation to the angle hair phenomenae, but I had not heard anyone but me apply the electrostatic repulsuion principle to it until now.

            So that is why, from 5 years old, I've always known the academics often simply don't know things that even a 5-year old can see. I realized at that young age "Science and "experts" do not always have the answers". In fact it is easy to see this: How many doctors spent their lives explaining how millions of ulcers were "caused by stress", until someone finally noticed they went away when people were put on antibiotiotics, being in fections caused by heliobacter pilori? How about decades of cardiologists recommending partially hydrogenated vegetable oils (margarine) as a cure for heart disease for decades on end? What about "Eggs, not as bad as we thought"? Extrapolate to "global warming" and all the rest: scientists are clueless at least half the time. 

            Since then my attitude is "I know things nobody else knows and sometimes the academics and experts, in at least one case, and probably others, have no clue". That's why you can hold up anyone from NASA to MIT and I laugh - maybe they know, maybe they don't. Perhaps half the time, they don't. I never heard them explaining angel hair. They all denied even "ball lightning" (also appearing in the same books of unexplained phenomenae as "angel hair") until video of it began to accumulate and they could deny no more. And yet the scientists dare to call others "deniers" while the entire process of science is to deny anything until it is proven.

            I went on to predict that planets were everywhere back when "official science" seemed to think it was doubtful other stars even had planets, let alone life. I predicted life was everywhere in the universe, while "science" still maintained life might most probably only exist on Earth. 

            I understood the reason why we have an appendix, as a repository for beneficial bacteria (a "starter culture") long before academia ever figured that one out. For most of my life the story was "Nobody knows why we have an appendix". I really thought "how long can these supposedly smart people operate on infected appendixes before they figure out the reason they are filled with bacteria is because that is the purpose?"

            I know lots of other stuff the academics are clueless about, such as why we have a chin, and of course a hundred easy ways to do AWE.

            So if anyone wants to understand my humorously skeptical attitude toward academia, the electrostatic balloon spider silk phenomena is the root of it all. I knew about the electrostatic repulsion of balloon spider silk long before any "experts" ever even contemplated such a thing.

            Doug's error, at five years old, is in prematurely supposing no one had ever thought this before, in order to support a lifelong narcissistic scientific self-narrative- "I know things nobody else knows..."   

            According to Joe's cited source, Darwin himself presumed that electrostatic forces assisted spider ballooning. In the case of AWE, Doug has been unable to establish what he knows that no one else does.

            The electrostatic effect here is primarily to spread the filaments out to reduce sink-rate. The rest is simple statistics of mixing layers of wind, when mixing propagates upward faster than a small spider sinks. Sadly, this mechanism does not scale to much larger objects in normal winds.

            Open-AWE's emerging periodic cellular architectures are intended as optimized combinations of Kite-Matter ("rag and string") capable of variable response to specific excitation conditions of wind and load demand. Kite-Matter is thus formally a Metamaterial, a cutting-edge topic in materials-science (with hundreds of published papers), and subject to the laws of condensed-matter physics-

            Phys.org- 

            The term [metamaterial] was coined in 1999 by Rodger M. Walser of the University of Texas at Austin. He defined metamaterials as macroscopic composites having a man-made, three-dimensional, periodic cellular architecture designed to produce an optimized combination, not available in nature, of two or more responses to specific excitation.

            On another sunny and windy winter day in Austin, TX I was able to demonstrate the viability of a 2 line pilot-lifter kite using a simple bridle adapter made from a piece of knotted chord about 18" long which integrated the 3 left, 3 right and single center lines to the two control lines which I held with handles. Although very crude, the adapter worked, allowing me to steer the kite slowly back and forth. As can be seen in the video, I was even able to save the kite from crashing by virtue of the handles.  Also in the video, I released one handle to demonstrate the effectiveness of redundant tethers to maintaining control of a kite (system).The kite was not killed (as an arch would have been) but rather maintained stable flight as a single line kite...

            Nice test, Ed. 

            What you add here to the two-line no-runaway concept is a kite that steers (sweeps some and parks tacked) usefully, but does not stop flying if one line is lost. We can even design for a centered kite when one line is lost. The challenge is to figure out how to still kill the kite, without runaway, when it defaults to one line. A small diameter tagline to a kill-point on the kite seems required (or small aux four-line "kill-kite grapple" option). I'll be testing auto-kill rigs next, here on the NW Coast, when we get a dry day with wind. Perfecting pilot-lifter rigging and operations unlocks the sky, on-the-cheap :)

            Yes, either collective pitch or disc AoA can be used for depower. SkyMill began in favor of AoA modulation,  to avoid the mechanical complexity of a collective-pitch hub, but this can change if desired.

            Stopping  the rotor for low drag retract is a possible new idea that you pose here. A single "two-blade" rotor would have very low drag in a "javelin mode", so it could be a real contender in reeling circles. Many AWES autogyro cycles and operational modes are possible. SkyMill is supposedly active in stealth-mode, so its not publicly known what cycles and modes they are down-selecting.

            Fort Felker's 2010 AWE conference presentation, from his perspective as a top aviation and wind power subject-matter expert, contained an astounding conjecture; that economic AWES aviation platforms would have to cost less than five dollars per pound. He noted grimly that conventional aviation transports cost around five hundred dollars per pound.

            Call the five dollar cost test "Fort's Criteria". To begin to test Fort's Criteria, kPower managed to make and fly Mothra for just under five dollars a pound (rope and tarp bought wholesale, whose polymers cost a under couple of dollars per pound, on the bulk market), with good lifting power (to lift WECS or pump groundgens). This showed that Fort's Criteria is at least marginally achievable already. Engineering progress would bring costs down further, while still upping performance.

            Fort's Criteria may be a sound heuristic* to early-pick AWE's winning architectures, but we won't know for sure until the current field is shaken-out, to see what is left flying after many hours.

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

            Joe,

            Fort surely agrees with you. Felker's Criteria adds an aviation-perspective hueristic to the LCOE truism. Cost of energy is roughly proportional to the cost of flying mass aloft and power-to-mass. We can also stand with Wubbo, who taught us to transcend mundane considerations to create the AWE we want (as an aviation civilization).

            What Fort was also trying to express in a 15 minute talk, but could not cover every key detail, is the barrier-to-entry effect of high-capital cost: if you have to pay aerospace pricing to bring AWE service to low-income populations, financing is not going to happen soon. The billionaire class will eventually get its $500lb AWES showcases (via the usual subsidies), but rags and string are happening now for the rest of us; are more fun; and satisfy Felker's Criteria.

            Kite sports already prove an acceptable LCOE, in any case,

            Assuming you want to implement this on the cheap.. eg use it on isotropic kite mesh nodes then consider ...


            The two lines (if only 2) to the kite want to be lifting the node yet easily adjustable with minimal input.
            The node place has to allow full rotation of the kite.
            Assume the node is connecting point of net lines onto a wheel rim.
            Control of rotation and kite behaviours can be done remotely with local microcontrol or mechanically from the ground.
            The hub bearing is hollow and allows a lower side gear driven by a curtain bead line section to turn an upper side capstan affecting left and right steering lines...
            Most lift lines could be set directly onto the hub.

              Firstly I would like to mention that it was a pleasure meeting some of you at this past AWES meetup. Seeing Dave Santos' giant parafoils on the beach cemented my thoughts of the practical nature of wind energy and its uses in the future. I really wish I had more time, I really came on a whim, wanted to check out the atmosphere and didn't have the chance to bring my machine; however the new prototype should be up by mid spring. 

              This post really piqued my interest. I am in the process of prototyping my second version of a system that uses these principles. Instead of a two line pilot kite, I use a 2 line 2.1 Symphony parafoil in the same fashion. If you imagine a torus the "A" line would thread through the middle and the "B" line slews around the outside, thus orbiting the B line around the A line (line twist solved with gimbles).

              In my opinion this would be an improved version of dave santos technology. If this kite was designed to perform loops, it could be set to perform differently by sheeting the main "A' line. This way the kite would be able to steer anywhere in the wind window with a jigging motion of the "A" line. 

              It could also have gust protection, The possibility of deeper, faster loops, aerial algorithmic acrobatics, depower, reeling... 

              The beginning of the video is a couple of proofs of concept for another related project. Dave, if it ok with you, I would like you to consider me a member of K Power

              Here is a link to the work I did last year on this subject


              The new OKE proto. This version reels line in and out, has a depower function and loops the kite without tangling line. 

              ​

              Looking for suggestions on the best parafoils to use, My rig should be able to handle about 400lbs and steer acrobatically. Tighter loops create more speed and power  (sans 4-line kite  "drag loops") 

              In the future the system will be automated but for now, it requires a human to sheet the "A" line until an algorithm is found.

              Rod,

              Its true, we don't have a good manual way to kill a kite on a swivel. We can use a BMX trick-bike headset pass-thrus, but this adds a chunk of weight and cost. My current scheme is to kill upwind LE kites (not on swivels) of an iso-dome and the dome should then haul down easier, despite the lifters still flying in the mesh.

              I like the idea of a small four-line gappling kite to kill large parafoils. With practice, it should be a handy method,

              Christian,

              Welcome to kPower (note to Ed). Anyone who can bring value to the RAD (Rapid AWE Dev) goal is eligible for a founding stake of equity and royalties (which are still mostly speculative).

              Yeah, we had a wonderful day at the World Kite Museum, and the flying session was an ideal intro into basic large-kite handling. I can't take credit for the rig design, since its mostly standard, but I do stand for the philosophy to first master cheap commodity lift, and let the WECS and other payloads be an open subject.

              Good luck with your prototype. I hope you can network with the other SeaTac AWE figures- Ken Conrad (whom you met), Dan Tracy, Jeremy Calvert, Dave Lang. A Seattle meeting would be great. Be sure to look up Bazzer and also Prism Kites, to see cool kite design from the NW.

              Keep the upcoming (mid-late Jan) WKM indoor kite fest and Robert Brasington visiting master workshop (he is also the Ninja turbine rotor designer for KiteSat). Hopefully you can come and fly some new stuff, and meet more KiteGods,

              Nice association of these tethered energy subs as Kites. A long debate whether the "K-word" is toxic is over: "Kite" won.

              We see a similar trend to wind towers and AWE in "underwater wind". Now Toshiba, the Japanese industrial giant, joins a swelling field of kite starts. Otherwise there is not much to add here: A bare concept, artist's rendering, and press release,is far from a real deployment, and there is little to judge from scant detail.

              Subject: PowerBuoy (TM) as Industrial COTS Offshore AWES PTO
              Its an old idea, but the PowerBuoy is now available as a megascale COTS unit (45m overall, 866kW) that not only can tap waves, as intended, but in principle can be pumped by kites (maybe as a "summer-mode" in winter-storm locations). 

              A baseline rig idea is a simple pulley anchored on the bottom to direct kite pumping down to the anchor, then up to the  power buoy. A big operational advantage is keeping the power generation plant at the surface. An open question is mixed-mode advantage; if wind and kite can be mixed for higher capacity. The kite would have to phase with the waves, and might be useful to smooth wave surges or gaps.

              Even ocean currents could be tapped, for yet a third-mode; if the power buoy had an oscillation basis added (like flap-valves in its heave-plate). It would make an interesting study to have a large clean-energy plant with three modes, but there will be many more cases where one mode dominates, and storage or smart-grid solutions beat multi-mode complexity.

              Its up to us to refine the kite pumping tech, whether or not the PowerBuoy ends up being the driven unit, or something better.
