    A traditional cableway is slow and must bear the total payload mass. Instead, a light cable acting as a high speed zipline could conduct large masses of self-propelled winged cars; nice potential for fabled "Celestial Railway" to become real, but instead of heavy track or cable, perhaps just a thin string to guide considerable flying mass at high speed. In case of a line break, free-flight to a safe emergency landing would be the default.

    Zipline-based aviation is basically the idea as Alexei Bolonkin proposes in fully airborne form, but works from terrain as well. Zipline aviation not only enable low-complexity densification of airspace, but conceptually advance terrain-based cableway tech, as winged cable-cars.

    Subject: Scaling Up Rope-Drives
    GordonS makes interesting comments on someAWE in the context of KiteWinder's architecture, which is essentially the same as KiteLab PDX Kitemotor1, 2007.

    Its quite true that the general Kitewinder/Kitemotor1 design is best suited for small AWES. Its not so much that rope-drive working tension drives the limit, since high rope load-velocity by the transmission gear ratio at the rotor effectively reduces rope-drive working tension well below the static tension of the whole rig at any scale, which is a fairly linear dimensionless relation. Instead, the main scaling limit is simply the square-cube mass penalty of a rigid 3D rotor scaled up.

    It might indeed require about 40m2 for about 10kW rated system (which a two-stack of 22m2 PL PL might provide), but the determination of kite safety is more complex than simple area. For example, a 300m2 SkySails ship kite is safe to operate by design, but even a 2m2 power kite may kill you in the wrong conditions. There is also the scaling issue of falling-mass hazard of the rotor, quite apart from kite area.

    Rope-drives themselves scale well, since kiteline is quasi 1D, the least affected transmission method by square-cube scaling, and the designer can make sure load velocity is high enough to meet the tension allowance. For launching and landing forces, reeling out to launch and depowering to retrieve moderate tension in established practice.

    Gordon is quite correct to suggest an AWES design that works well at a given scale often is unsuited to work at another scale, but many scaling factors are usually in play.

    Gordon Spilkin

    Kitewinder is a very good system for creating small amounts of energy.  Unfortunately scale-up is a severe problem.  For example to generate 10 kW of power we require a lifter kite of area greater than 40 sq. meter.  A lifter kite this size is dangerous to launch and retrieve in moderate to high winds.  The large kite is required because tension in both ropes of the cable drive must be maintained while power is being extracted.  Operating the lifter kite in crosswind mode would increase the lifting force, but operating in a figure-of-eight pattern would result in uneven pulling forces.  Perhaps a circular crosswind pattern would be satisfactory.  In any case, crosswind would require a  "Kite Control Unit" which is complicated.

    Whoops, forgot to mention the increased hazard of a larger rotor in high-speed rotation hitting a person, and also the hazard of getting fingers or limbs in the rope drive. 10kW is enough WECS power to cause serious bodily harm or death, kite area aside.

    Naïve observers of AWE R&D underestimate the grave safety challenges of scaling up, but Gordon is quite correct to pose the issue. The good news is that aerospace safety-culture is able to achieve high safety over time, such that a jumbo jet, for example, is statistically safer for the user than a home bathtub.

    Subject: Re: Scaling Up Rope-Drives

    I am curious to know how much the rotating turbine contributes to the tension in the tether/cable-drive.  How do we calculate this force?  In my design there are multiple turbines which are an integral part of the tether.  Can we use the forces of the rotating turbines to replace some of the area required in the lifter kite?  These forces increase with wind speed so we can allow higher differential tension in the cable drive at higher wind speeds.

    Perhaps my idea of a cage wind-up system will make the bottom cable-drive intrinsically safe.

    Subject: AWEfest BETA successful
    Ambient Camping 47 finished yesterday on the North Padre Island National Seashore, with about 200 participants. The event especially featured kites and AWE; another baby-step toward a major AWEfest world-tour. Winds were high all three days, 15-25mph, without pause. Sat night was the climax, with a kite-based light show in the sky all night long to the pulsing grooves of elite mix-Djs.

    AWE was mainly phone-charging with a KiteSat, with misc other frantic demos for short periods, since the winds were too high for larger AWE demos designed for less wind. It was in fact a sand-storm, difficult to work and fly in, and a few kites broke sticks or tore fabric, but got fixed and relaunched; very good operational training. Low-complexity AWE is basically sailing in the sky, and just as sailors train and drill diligently, so do kite pros.*

    The consensus is to grow the role of AWE and solar in Ambient Camping events, until we can do away with fuel-based generators. For now it going to be an AWE hybrid event. There was a lot of musical and technical talent very appreciative of the kite, and some of these folks want to carry forward AWEfest and do kite-themed sound design for the AWE documentary. Lots of new friends to AWE. All in all, a fine experience.

    Subject: Kitefarm Load-matching by Multi-Quivers for Constant-Force Variable-
    Kite sports based on the power kite are the grand incubator of low-complexity AWE. What works in sport works in industrial practice. The following is not the only way to organize a kitefarm to match wing to wind and load, but its the sport kite model, and prove the best in future kitefarm use.

    In sport use, a range of kite sizes covers normal wind variations, and also variations in user mass and aggressiveness, for quasi-constant unit-kite force. A popular kite sport location with many active participants is in effect a multi-quiver, and the number of participants is an indicator of total load demand.

    Kite farm operation will be similar, utilizing multi-quiver organization. It won't be enough to have a single unit-kite station with a single quiver of kites, but multiple quivers such that each unit-kite station has its own quiver. Depending on load-demand from the grid, constant unit-kite outputs will be brought on or off.

    There are other less-basic power less tunings to assist in matching wind to load, like kite depower, or parking at the edge of the kite window. Multiple means are more robust and adaptable than just one. Quivers also mitigate UV damage compared to a single kite. It may become common kitefarm practice to constantly change kites, just as kite pros already do.

    Subject: Re: Kitefarm Load-matching by Multi-Quivers for Constant-Force Varia
     A corollary to this latest discussion of kite quivers is that furling kite surface is not as applicable as was hoped for AWES. The reason is a bit subtle; a kite at its farm does not have to carry all its "state changes" like a long distance modern airplane wing carries its flaps and slats or sailboat carries a sail suite. Carrying furlable mass aloft would mean less net energy production than leaving the mass on the surface. Better to furl or add sail by landing and relaunching a different kite.Open racing sailboat classes change sails the most, the winning boats better able to make fast changes, which in fact win the races.

    An exception is in the highest wind range, with lots of excess power, and furling as a survival means. The common leaf and delta kite both furl by curling to endure peak gusts. Bluewater cruising and working sailboats furl with few or no sail changes, but a kitefarm kite has more options.

    Here is a partial list of engineering methods to modulate kite force that are not quiver changes-

    Adding to our fragmentary picture of ancient Chinese kites; if Mozi developed a large lifter rather than a toy, that better fits the idea kites were far more ancient still. Li Ban is enabled to use the design for reconnaissance, which required an observer aloft. This is the oldest record of human flight slowly leaking into Western notice.

    So, the fixed-anchor "figure of eight" in much kiting is not a lemniscate, but more a Viviani's Curve, as the path is on a surface of a sphere, not a flat plane.  ​

    Subject: Re: Kite Lemniscate is Viviani's Curve
    Its not just the satisfaction of a more exact geometric identification, but a whole new trail opening up. Of course others have used spherical coordinates with a figure of eight orbit, but not very elaborated. Viviani's abstract cylinder piercing our tangible kite window is a hoot. Noticing the wind more "sees" the frontal projection Lemiscate of Gerono, not so much Viviani's,  to the degree air shears freely and cleanly. We are only considering a subset of possible Viviani Curves, those that stay in the kite window. We can also define a kite loop as on a sphere, although the loop is planar.

    Noticing how natural Viviani Curve kite trajectories encode as Bloch Sphere qubits, surface-constrained kite tethered to spheric center. In the case of a classic kite, half of the sphere is underground, presenting an opposed phonon "gas" force map. Tethered wing pairs nicely trace entangled qubit trajectories on the Bloch Sphere. Opposed Viviani-eights and looping orbits are basic minimal motion default solutions, while endlessly unique chaotic orbits are normal reactions to turbulence, and too-little or too-much wind. The gradient also figures, as well as asymmetric Viviani Curves by conic piercings of the window.

    Subject: Estimating Makani's Current Prospects
    Makani's long-predicted prospects are playing out in accord with analysis going back to 2007. The general challenge for the high-complexity M600 AWES architecture is combined scaling, reliability, safety, and economic issues, with an open question of competitiveness against varied alternative architectures, all of lower complexity.

    Based on what we know is happening now, Makani is struggling to show higher net power over the many parasitic power factors. The expected next step is to fly the M600 in higher wind, which should show an improvement in net power. As they fly multiple prototypes, luck should allow a spectacular all-modes session, to overcome the shadow of the supposed crash of the maiden-flight. *

    A successful M600 all-modes session would be hailed in popular media as tangible evidence that AWE is workable, but the underlying technical and economic challenge will remain. Lower-complexity architectures will experience the accustomed mixed impact of greater overall public AWE awareness, while continuing to be eclipsed by GoogleX's mindshare.

    Future uncertainty is mostly whether Makani will be cancelled or sold off, as other GoogleX underachievers are, or will somehow "retool" by a radical architecture change or research diversification. A merger with AWESCO circles even seems possible, based on elite academic and corporatist social affinities, but the respective AWES architectures are far apart, and neither may prevail long term.

    ------------
    * I had a long strange AWE dream last night, with a large cast of characters, where, in passing, Don Montague told me the M600 had not crashed, but flown twice to date. My waking self awaits verification.

    Subject: Re: Search for the Super Battery (New Documentary)
    There are multiple connections between AWE and evolving battery tech. In general, AWE is a prime charging basis across many storage methods, but there are special integrated architectures that could someday become important. AWE-driven pumped hydro seems promising, given the cheap bulk lifting potential of kites, as well as fuel synthesis powering.

    We have also considered lifting batteries to altitude to charge them. A sort of battery laddermill could lift a loop of batteries, with flygen turbines attached, where discharged batteries rise up and return to the surface charged. The descending side mass offsets the lifting side mass just like elevators use a compensating mass.

    A possibly new AWES idea is suggested by the Flow Battery, where working fluids rise and fall in charging and discharging modes. There are many exciting possibilities to consider. Yes, most of these ideas will not be the most economic, but the chance of a major new technology is real. Recognizing close IFO concepts that Gabor has described, the exotic concepts of energy storage aloft are mostly Open-AWE_IP-Cloud.

    These concepts are a wonderful open opportunity for talented prototype hackers to pioneer. About the only case so far is KiteSat lifting cell phones to charge aloft, that then return to Earth ready to use.

    Subject: Re: Physics of Tension not obvious
    Clarifying that tension is in many ways dynamically equivalent to electrical charge, but not the same thing. Physics advances by exploring analogies as much as by making distinctions*. No doubt electrical science is informing modern mechanical knowledge. Mechanics informed electrical theory from the start, and could still illuminate new understanding; in particular, better understanding the electron.

    In the case of a photon modeled in 2D as a circular ripple on the surface of a pond, we can see the "string" in the expanding ring and posit a tension to it. Note that particle-wave duality is explained by a point particle sensor sensing only the wave-front that hits it, but not sensing the whole expanding ring. Entanglement is merely the phase correlations that all parts of the expanding ripple maintain. Two particle detectors can detect such entanglement without revealing the overall pilot-wave field. What is obvious in the water wave tank informs what is obscure in the light chamber. Light delineates macroscopic waterwaves, but we have had no probe sensitive enough to delineate light waves without decoherence.

    Perhaps we can reverse this one-way observation window as follows- Wave a magnet by hand, and you create super low frequency light. Nearby magnets will move mechanically in sympathy, as optical-phonon detectors. What could be simpler? A child can do such experiments. Great new science is still being done by the simplest means, based on deepening ideas.

    Subject: Keeping Drag Force in Play
    AWES concepts range from sleek high L/D wings to simple drogues. It may well be that the best general choice lies somewhere in-between, like power-kite derivatives, but the AE testing ethos requires all concepts be studied, since even losing ideas reveal lessons in testing and put to rest undue investment promotions. While lift force is conventionally favored over drag force, the theoretic optimum in many cases is a mix of high-lift and high-drag.

    A simple drogue develops almost pure drag force, and is the one "wing" basis, on land, that requires reeling groundgen operation. Its crosswind component is simply its large crosswind area, swept during inflation. The drogue WECS is intended to furl for a fast (possibly ballistic) upwind return phase. On paper, quite high efficiencies are possible, but this is not a sexy design path. Supposed design advantages are super-low complexity and capital-cost. Imagine a 2000ft diameter droque, fitting the FAA airspace ceiling, and hauling downwind powerfully at a low angle. A demo might involve just wrapping the hawser-tether on a generator shaft to claim an AWE peak-power record.

    kPower was willing to buy a 12ft diameter play-parachute for only 15 USD for specific drogue AWES experiments. It took a few minutes to bridle the handles, and the result is a dirt cheap WECS for its potential power, that pulls like an ox in a fresh breeze. Various follow-on tests will assess practical pilot-lifting, reeling, and furling options. Who knows, maybe the humble drogue with pure drag will perform well enough to continue in play along with all the more popular AWES concepts. kPower makes no claims for the many fringe concepts it tests, along with the ship-kite derivatives that are kPower's emerging down-select, as all AWE contenders line up with their varied down-selects. Let further testing prove to the world how AWES concepts really sort out.

    Drogues in water represent less apparent risk to sea life than faster paravanes. Power drogues might even figure in sea farming or harvesting with less bycatch than previous tech. We have noted the right fish species might harvest algae on sea-kite surfaces, controlling fouling while gaining market weight. Sea drogues would move so slowly, in grand parade, with large current shadows as well, that quite a population of higher sealife might attend. Mixing up thermoclines and boosting oxygen could be part of an enhancement effect.

    Subject: IFOs favored on the wind, circumnavigating...
    Dave Lang once asked Gabor about IFO capability holding against a prevailing wind; whether the energy glider could keep station (like it could ridge-soaring or terrain-DS). Gabor rightly asserted an IFO in principle can keep station, by DS in sufficient gradient. The prediction to add here is that keeping station in wind, without enabling terrain effects, is parasitic to harvestable power.

    This leads to a specific IFO solution for global operations of vast flocks to range on the wind, progressively visiting downwind stations to discharge, to eventually "pass go" (home) again and again. IFOs are thus inherently circumnavigating energy aircraft, in their largest application space, much like albatrosses of similar wandering ways.

    Subject: Re: Seismic Love Wave dynamics applicable to AWE Bloch Waves
    Some added notes-

    Love Waves are channeled in horizontal layers of variable density, with polarizations oriented by gravity holding for theoretic kite metamaterial layers.

    Energy harvesting of a kitematter wave is an attenuation process similar to normal attenuation. Like any wind-wave, kite-lattice waves are 'fed" energy that is extractable in proportion to the extra energy not needed to maintain the carrier wave.

    Tsunamis (water seismic waves) are an interesting energy transport model for kitematter, but we presume higher attenuation and thus shorter distances for kite-lattice waves, due to lower Re.

    Seismic Love Waves are not an exact analogy for AWES metamaterial waves, since they originate all at once and travel long distances, but the specific motion in travel looks close to the specific motion a kite lattice might sustain.

    In the end, existing wave functions in math, science, and engineering are at best partial models for a unique set of AWES metamaterial wave functions, since no prior model can be an exact match to our unique challenges. Reuse of standard math is a primary benefit of similarity-case logic.

    Wind-waves are one more model to mine, especially how many small wind-wave interactions sum as WECS units into powerful coherent large waves-

    I myself passed over a pod of pigmy sperm whales while at the helm of a large sailboat under power. The owner was vexed that I instinctively cut the engine, to ensure the safety of the whales in those dangerous seas off the Columbia Bar (Graveyard of the Pacific). We had done some kite-sailing shortly before, but no kite was up at the time. The engine came back on, no problem.

    As an AKA judge, this incident hereby counts as the whale actually flying a power kite for the instant it bore the rider. Before we only had cases of dogs and horses flying kites, as service animals, not mega-wildlife. Apologies to the whale, who may bear a dueling-scar from the rude encounter.

    Subject: Telepiloted AWE
    We have noted before possible advantages of AWES teleoperation, but not fully explored the idea. The urgent problem is that kite flight automation remains brittle as long as so many unprogrammed events can interfere with nominal operation. On the other hand, its rather limiting if human presence is required on the kite field 24/7. Human teleoperation is a solution that could enhance safety, capacity, and revenue, while reducing costs.

    A remote human flight supervisor has the potential to manage a huge amount of flight operations, including multiple kite farms. Automated alarms could indicate control anomalies for the human to selectively analyze. A human telepilot could allow continued operation that imperfect automation could not easily clear, like ignoring a sensor or local structural failure, and temporarily switching to manual modes. Self-stable flight of large metamaterial kite formations is the best foundation for human pilot supervision. Large numbers of isolated flight units with independent autopiloting, as most AWES developers propose, are less suitable.

    An AWES telepilot would depend primarily on directed multi-video to scrutinize the kitefarm scene, but also weigh data dynamically from many sources. For example, if flight automation sensing and control lacked any knowledge of rare events, like a nearby crop duster, a bear crossing the field or a dust storm, the human pilot could override a default shut-down. In cases of cyberattack, human telepiloting can provide backup override control.

    Telepilots could be located in daytime zones conducting night flight operations, eliminating excess night shifts. Local response workers could sleep in peace most nights, watched over by alert pilots on the other side of the globe. No doubt the transition from manual AWE piloting, and PIC/VO requirements, to fully automated AWES, will long involve some measure of teleoperation. After all, modern smart grids are increasingly manageable and flexible by remote human supervision hand-in-hand with distributed automation.

    Job description

    The PhD researcher will investigate the performance of airborne wind energy systems, with a particular focus on the Kitepower™ system and scaled-up derivatives, and will explore the potential of further power augmentation by systematic optimisation of operational parameters as well as system-level and component-level designs. The tool base to be used includes a quasi-steady model for pumping cycle operation of the kite, as well as a dynamic model in which the kite and the tether are discretised as a particle system. He/she will use time-resolved measurement data of parallel test campaigns (apparent wind velocity at the kite, position, orientation, time derivatives, tether force, etc.) to validate and further improve the models and the safety and reliability of the systems. Kite aerodynamics will be a central topic and an interface to other research activities of the team. Sensor fusion and state estimation could be explored if the quality of the available measurement data is insufficient. 

    Requirements

    Applicants should have an MSc degree in engineering (aerospace/mechanical) or applied physics. Also required is a combination of good mathematical/analytical skills, solid programming skills (Python), a very good command of English (working language) and an interest in performing experimental research. An active involvement in the development, operation, and testing of the demonstrator platform is desired, as well as a good team spirit and the ability to function in a multidisciplinary group.
