Subject: New Generation of Ultra-Light Kites
Damon has taken indoor UL kite design to new performance levels. Thanks to Mark Thorn for showing me a Feather at the Indoor Kite Festival, but the claim of L/D 300 seems high, at least with thread attached. These wings operate in a magic realm of slowest flight, lowest wing loading, and optimal scale. The pattern is classic fighter-kite. No other sort of wing comes close to this marriage of modern materials and ancient aerodynamics.

Just don't sneeze while flying the Feather, the standard warning goes-

More notes and links on Joby/NASA LEAPtech concept-

My opinion is that so many propulsors on a wing may solve the heat dissipation problem, but compounds the problem of creating a clean wing with mass concentrated toward the CG. A possibly superior concept is to take all the little motors and gang them in stacks on a planetary gear driving a larger single propeller (Open-AWE_IP-Cloud).

-----------------
In the original link, the CAN EMI data screen-shot only shows one channel (#6 of 18) with low noise, with about half the channels with very high noise. One channel (2) is dead. The timeline turns out to be for TRL-6 only. NASA def.- "...a technology that is at 5 is identified as a breadboard technology and must undergo more rigorous testing than technology that is only at TRL 4. Simulations should be run in environments that are as close to realistic as possible. Once the testing of TRL 5 is complete, a technology may advance to TRL 6. A TRL 6 technology has a fully functional prototype or representational model."

TRL6 is still far short of the goal of full validation and availability, so the long LEAPtech timeline is even longer, if ever, for TRL9
-------------------
Flygen AWE's NASA champ, Dr. Mark Moore, on LEAPtech cited on another webpage regarding LEAPtech-


Mark Moore- “LEAPTech has the potential to achieve transformational capabilities in the near-term for general aviation aircraft, as well as for transport aircraft in the longer-term.”

-------------------
Armstrong flight research center (Edwards AFB) home page highlight-

Electric Aircraft Propulsion
The arrival of a unique experimental demonstrator at NASA Armstrong Flight Research Center on February 26 may herald a future in which many aircraft are powered by electric motors. The Leading Edge Asynchronous Propeller Technology (LEAPTech) project tested the premise that tighter propulsion-airframe integration, made possible with electric power, will deliver improved efficiency and safety, as well as environmental and economic benefits. Over the span of several months, NASA researchers performed ground testing of a 31-foot-span, carbon composite wing section with 18 electric motors powered by lithium iron phosphate batteries. The experimental wing, called the Hybrid-Electric Integrated Systems Testbed (HEIST), was mounted on a specially modified truck. Testing on the mobile ground rig assembly provided valuable data and risk reduction applicable to future flight research. The HEIST wing section remained attached to load cells on a supporting truss while the vehicle was driven at speeds up to 70 miles per hour across a dry lakebed at Edwards Air Force Base. The LEAPTech project began in 2014 when researchers from Langley and Armstrong partnered with two California companies, Empirical Systems Aerospace (ESAero) in Pismo Beach and Joby Aviation in Santa Cruz. ESAero is the prime contractor for HEIST responsible for system integration and instrumentation, while Joby is responsible for design and manufacture of the electric motors, propellers, and carbon fiber wing section. The truck experiment is a precursor to a development of a small X-plane demonstrator proposed under NASA’s Transformative Aeronautics Concepts program, and which may fly within the next few years.

A few more observations of the Joby/NASA work-

The closest to "whale bumps" on a wing are the wing motor pods of Joby's concept, but with no comparable advantage. Its obvious that this is a very high drag aircraft design, with a lot of frontal bluff-body drag (unless prop-spinners are added), skin-drag, and internal aero-mechanical drag (the current propellers do not fold, but windmill to idle).

The CAN embedded controls Joby/NASA are using are from National Instruments, in Austin; again underscoring the dominant position of NI across elite AWE R&D worldwide (Ironically for kPower, NI's capabilities are still too extravagant for our down-and-dirty low-complexity test style across many AWES architectures, and would only slow us down. As we eventually make definite down-selects for productization, then we'll adopt the NI tools, which we have a 30+ year home-field head-start advantage, with NI's huge design bureau in Austin).

Joeben himself is in the NASA group shot, in his standard black suit, white shirt, and no tie. The NASA team, however, from PI on down, clearly now "owns" the concept  Joby is being relegated to only being an experimental motor supplier, which is a small shaky foothold, given how competitive the high-tech mass-motor market is getting. Based on the NASA timeline (and standing Forum predictions), we clearly are not about to see Joby offer the personal playboy e-VTOL aircraft, now several years in "preorder" stage.

The NASA investigators cite "low TRL components" under the "Challenges", which is further evidence of the long timeline of the high-complexity path. We are several years past Joby/Makani's market-entry claims, as scrubbed from the old web pages. A growing circle of experts beyond just the AWES Forum should be becoming aware that the Makani M600 may not be able to fly at all, much less net any watts, which would be a major AE scandal. Like NASA in this case, the Honolulu FAA FSDO is in the cat seat for this engineering drama, and may be the only reliable source of public info.

One thing this research is doing right is operating from Edwards AFB in CA (just as ChrisC recommended here) rather than Hawaii.

Separating JoeF's rich link to a new topic; Joby Aviation, and its ongoing R&D in e-flight, with NASA now providing a public evaluation of the concepts.

Longtime readers of the Forum will recall Joeben Bevirt's high-profile entry into AWE, from a successful camera tripod product (Joby Gorillapod) to a misguided effort to lobby the US Congress and FAA to privatize airspace, but also for an AWES flygen concept that folded into Makani, and how this close partnership attracted US DOE and GoogleX support in the tens-of-millions total. The AWES Forum all along made specific critiques of Joby's political, corporate, and technical  assumptions, but there has been scant third-party validation or invalidation of these critiques, except perhaps as corporate secrets. NASA is spending the millions that will finally prove who was right or wrong on many questions, and public results are beginning to pile up.

The main old Forum critique is that the Joby/Makani/GoogleX's AWES cannot scale well enough to be safe and economic, at least for many decades. The new NASA timeline for eflight rated-power progress (which correlates to flygen eflight AWES by inherent Motor <=

Arch AWES

We have strong starts on the topic of arch AWES.

This topic thread is another home for growing notes and discussions on arch AWES.

I anticipate that one day there will be an encyclopedia dedicated to arch AWES

as a significant sector of AWE.   I'd buy a copy now if it existed. For now, may this topic

thread be part of the flow toward that future day.

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

In first blush "arch" brings to mind ancient doorways with keystones. Rainbows from the play of light and mist. Bridges from here to there. Tunnels. Sacred places. Strength. Power. Nests. Circle. Catenary. Connection. Community. And more.  The spider's web obtains arches by gravity and by wind, and by approximations from polygonal ways.

    Have a single-line kite system having one wing in its wing set and one anchor point in its anchor set. Someplace along the single line or at the wing, have a continuation of the tether to form a second return path to earth, mother anchor; have the elements of an arch kite system, the primitive of an arch AWES that converts wind energy to other forms of energy and works.   a____W_____a     might be a character symbol for such a primitive arch AWES; the "a" is anchor; the ____ a part of the arch loadline; the W the wing; and then repeat the other side of the arch.  Maybe a^w^a  could be an alternative for the same primitive. Then consider a^w^w^a.   "Etc.", as Newton would end a thought session.  


So, one could have:    a^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^a

Or going further for a farm:

a^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^a

a^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^a

a^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^a

a^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^a

a^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^a

a^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^a

a^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^a

a^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^a

Now the count of ws in each arch will be of concern for various purposes. 

And will there be flygen or groundgen arrangements? Perhaps both at once.


Now, a peek at the nature of "w" in an arch AWES: The "w" could be embedded in arch load lines or kited out from the load line(s).  Indeed, one "w" could be a train or downwind arch itself with multiple wing elements; domes of arches could occur (we have some former discussions on such).  And any "w" could be rigid, soft, hybrid, rotary-T (traverse-to-wind axis), rotary-P (parallel-to-wind axis), or rotary-O (axis oblique to wind).


Notice that from the arch load lines one my have drop lines that tail or go to earth anchor or to load lines of other arch-kite runs. On drop lines may be held wings, vanes, things, sleeping quarters, drying stations, turbines, etc.


An arch AWES may efficiently curb yaw and roll moments; and such curbing may be a PTO means on arch AWES designed for such.  Left, right, left, right, left, right, ... : damp such oscillations with pumps or electric generators and power the world!


a^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^w^a   may arch over a cities, rivers, rail roads, lakes, forests, expanses of ocean, shipping lanes, waters between islands, ...

Subject: Re: Arch AWES
JoeF,

A kite arch is a specific sort of "molecule" to us, as is the basic SLK.

You are suggesting a diagrammetric kite language much like Petri Nets Feynman Diagrams, Circuit Diagrams, Lewis Dot Diagrams, etc.. Such systems are schematic combinations of symbols laid out in a topologicial order, with geometric proportions supressed. A single kite is therefore a^w, a train a^w..., and arch, a^w...^a. 

There is a lot more to define to create a full kite diagram language, but you make a fine start. If we use old constant-width ascii characters, we can form matrices of kite symbols to define multi-arches and beyond. A set of matrices can define 3D structure and complex network topologies. We can create state-machines to capture AWES dynamics. There are many models to borrow ideas from (sample links below),

Subject: Classification of Tethers
Dave Lang is the father of AWE tether science, having pioneered AE theoretic, simulated, and tested tethers during his long career, over many years challenging AWE researchers to look deeper. His involvement with actual Space Tethers and forward-looking Space Elevators even inspired new conceptual hybrids of the kite principle in planetary science. In the last decade, open AWE also scours academic literature and commercial sources for tether knowledge, especially in key high-TRL applications like fishing, rigging, and related practices.

New AWES tether conceptual frontiers emerged, such as sonic relativity in long-line control inputs (variable c in tension-modulated tether), and 3D tether lattices on a vast scale. A profusion of tether types and methods were rediscovered or newly invented. Advanced tethers range from pure super-polymer at highest power-to-weight and lowest-drag, to composite structure with diverse added functions. Below is an incomplete list of tether types and concepts in raw-note form, awaiting others to someday bring due order to the engineering classification of the complex AWES tether space.

-----------------------------
Load Bearing Tether- eg. the common kite tether

Primary Load Tether- a line bearing the preponderance of a tensile load from a wing set.

Plain Tether- a single tensile material

Composite Tether- any combination of materials and construction for multiple functions

Conductive Tether- metallic electrical, RF coaxial, or salt-contaminated tether

Secondary Load Tether- leader, bridle, riser, killer, tagline, pendant, PTO (power-take-off), etc

Control Tether- steering line, trim-tether (AoA "brake" or D line), kill-tether, trip-line, etc

Lifter/Drougue/WECS Tethers- specific to basic AWES modules

Slack Tether- unloaded in nominal operation, perhaps as a backup or stop

Moving Loop Tether- rope-driving, payload transport XC and local pick-and-place

Pumping Tether- low-stretch oscillating load

Shock Tether- elastic, damped, 

Snubber- a tensile shock absorber, often elastomer with backup rope

Stationary Anchor Tether- most common primary tether

Mobile Anchor Tether- drag-line, FF connecting tether

Horizontal Tether- (surface-tether, aloft-tether, (cableway, guide-cable)

Multi-Tether- identical tethers acting in parallel

Gangline- branching from a primary tether, a tether with multiple payload units along it

Dave Lang is the father of AWE tether science, having pioneered AE theoretic, simulated, and tested tethers during his long career, over many years challenging AWE researchers to look deeper. His involvement with actual Space Tethers and forward-looking Space Elevators even inspired new conceptual hybrids of the kite principle in planetary science. In the last decade, open AWE also scours academic literature and commercial sources for tether knowledge, especially in key high-TRL applications like fishing, rigging, and related practices.

New AWES tether conceptual frontiers emerged, such as sonic relativity in long-line control inputs (variable c in tension-modulated tether), and 3D tether lattices on a vast scale. A profusion of tether types and methods were rediscovered or newly invented. Advanced tethers range from pure super-polymer at highest power-to-weight and lowest-drag, to composite structure with diverse added functions. Below is an incomplete list of tether types and concepts in raw-note form, awaiting others to someday bring due order to the engineering classification of the complex AWES tether space.

-----------------------------
Load Bearing Tether- eg. the common kite tether

Primary Load Tether- a line bearing the preponderance of a tensile load from a wing set.

Plain Tether- a single tensile material

Composite Tether- any combination of materials and construction for multiple functions

Conductive Tether- metallic electrical, RF coaxial, or salt-contaminated tether

Secondary Load Tether- leader, bridle, riser, killer, tagline, pendant, PTO (power-take-off), etc

Control Tether- steering line, trim-tether (AoA "brake" or D line), kill-tether, trip-line, etc

Lifter/Drougue/WECS Tethers- specific to basic AWES modules

Slack Tether- unloaded in nominal operation, perhaps as a backup or stop

Moving Loop Tether- rope-driving, payload transport XC and local pick-and-place

Pumping Tether- low-stretch oscillating load

Shock Tether- elastic, damped, 

Snubber- a tensile shock absorber, often elastomer with backup rope

Stationary Anchor Tether- most common primary tether

Mobile Anchor Tether- drag-line, FF connecting tether

Horizontal Tether- (surface-tether, aloft-tether, (cableway, guide-cable)

Multi-Tether- identical tethers acting in parallel

Gangline- branching from a primary tether, a tether with multiple payload units along it

Star Tether- a multi-tether of shroud lines, lattice junctions, etc.

Chafing-Gear- ruggedized tether sections at bearing zones (capstans, pulleys)

Segmented Tether- serial tether segment

Graded Tether- serial tethers of progressive variance

Tether Lattice- 3D geometries

Subject: Ampyx in Transition
Apparently Wolbert has replaced Richard as CEO, who has likely burned-out (looking distant and bedraggled in recent pics). A fresh-looking Wolbert is thus seen in Dutch media newly pondering old AWES conundrums, like whether to streamline tethers. Safety of Ampyx's high-velocity high-mass platform has emerged as an admitted barrier to further test operations over dense EU populations (as long predicted here, whereas Richard argued otherwise), so Australia or Canada are being seen as better testing locations, but these are very remote options.

The reworked website proclaims, "Ampyx Power is ready to scale up", against all appearances.  Very little technical information is shared, like how Ampyx finally intends to launch and land (although a landing gear was recently seen on a virtual model at someAWE.org). A 2MW 40m WS version is shown in crude graphic form, with the wildly optimistic claim that it might emerge in 2018. Scaling law suggests such large glider-like aircraft will be very hard-pressed to fly in most-probable wind with net power-out. Aviation similarity cases imply that validating cheap safe operations of such a large aircraft require a far-longer more-expensive better-staffed developmental process than Ampyx is currently running.

Strange claim that Makani only made power starting in 2010, since they were founded four years earlier. For comparison, KiteLab Group made power starting in 2007, with self-relaunching sleds as the COTS KIS automation basis. Surely Makani tested something in its first few years that generated power, if it fact really tested "many different prototypes" (no public evidence of broad experimentation).

Its quite false that GoogleX/Makani "finished" the M600 in 2015. The photos are nice, but Google's AWE hype is grossly misleading, as usual.

    Its as if there has been big Makani shakeup internally, followed by a mad scramble, for so many key positions to suddenly open where the new hire must "take ownership". Where are the scores of smiling past engineers who presumably performed in these roles to where the M600 could be fairly claimed "finished" on solveforx? How can GoogleX imagine itself to have a large aviation platform to market that has never even flown, much less passed safety and reliability metrics? Are they just pumping up the company in order to dump it on a naive buyer, as GoogleX has done before? Let's hope not :(

    After years of fuss, we soon get to see what GoogleX finally gets up, and how well it stays up. Old-school engineering wisdom suggests AWE's early winning lineage must out-compete all other AWES architectures on pure merit. At-the-end-of-the-day, lavish spending and over-optimistic claims will count for very little.

    Subject: Two critical AWES parameters that do not scale...
    We have reviewed engineering scaling laws for years now, to be able to predict how well various AWES concepts will scale. Simple square-cube law requires large rigid aero-structure mass to grow at the cube of dimension, which sets a rough scaling limit, but this is just part of the bad news. Thermal dissipation slows at larger scale, limiting motor, ESC, and battery performance.

    Not all kite design strategies are equal. As Dave Culp correctly taught via KiteShip in 2006, single-skin (SS) kites scale best. His friend, Peter Lynn, even turned his focused talent large SS. KiteLab worked out that pure polymer SS will surely scale to the Tropopause altitude limit. Makani started by claiming it would someday tap wind 10km high, but finds it can barely contemplate operating the M600 at .5km, carrying so much non-structural (parasitic) mass.

    A major badly-overlooked scaling limit is imposed by the AWE wind field itself. For a given location and altitude, the most-probable wind-velocity and air-density are constants, and major scaling up of an AWES concept is sapped by the fact that such constants do not increase in proportion to wing scaling. More bad news for large rigid wings compared to the far larger soft-kite competitors.

    Subject: Multi-copter COTS component basis for novel AWES ("FlyGen Fabric")
    We have marveled at recent progress in precision formation flying of robotic multi-copter UAS. Prices have crashed since the Austin Robot Group bought its first multi-copter back around 1989 (via a Motorola engineer working in Japan). Performance has greatly increased on all fronts; batteries, motors, and automation.

    An old AWES Forum concept is a "fabric" of small turbines to conquer the max HAWT unit scaling barrier by making a quasi 2D rotor "disc", rather than a massively thick conventional rotor. In effect, a vast flexible sheet of multi-copter rotors could act as one giant generating or traction unit. 

    This concept was posed at the UTexas AE dept, starting in 2009, where research was active on small flexible almost undestructable copter blades. The consensus has been that, in principle, this is a promising path, but the economic prerequisite was COTS small cheap robust mass-produced motor/gen turbines, but it was unclear just how fast such availability would emerge. It came faster than expected.

    Meanwhile, over several years, KiteLab Ilwaco did varied multi-whirligig and fabric embedded turbine demos, validating specific essentials. There was also a UK case of a similar AWES thinking, about five years ago. Pierre's turbines in a Delta kite planform also come to mind. SkyWindPower's concept is sort of a rigid conceptual ancestor. All of a sudden, a vast consumer market in multi-copters has sprung up, and cheap motor/gen turbines are here. No longer are multi-copters an expensive homebrew technology. With modest funds, one can buy a large number of COTS units at reasonable cost. 

    The general idea is to string many copter units by their prop-guards into a large flying 2D network unit, wiring in series-parallel according to electrical need. Initial proof-of-concept could start as a simple flygen-fabric lofted by conventional lifters, and soon evolve into a spooky new "flying-carpet" technology, with many strange flying tricks possible, not just scalable flygen power generation with launch and land capability. Flygen-Fabric is one of kPower's special areas of technical exploration, seeking to fill theoretic gaps left by other players.

    Electronic Speed Controller- ESC

    E-flight motors need ESCs to throttle power on command. These are hard-driven critical components that add weight, expense, and failure modes. Over-worked, they can explode in flames, but even just simple failure can cause a crash. ESC RF noise is also bedeviling NASA's LEAPtech. ESC issues are no doubt a major Makani concern. Dual motor-gen modes complicates the problems. Obviously, its preferable to avoid ESCs in AWES, but SWP, Makani, and even Ampyx are counting on them.

    An old-school low-tech alternative is electro-mechanical relays driving simple dynamo/motor units, using large capacitors to smooth the surging currents.

    JohnO,

    It would have only been reasonable for F&S to communicate directly with leaders in AWE, rather than just read about it. You do have a choice early perspective to help inform the financial sector about AWE, given how the prevailing hype by a few high-profile ventures has distorted the picture.

    We do want to somehow read F&S's report without paying a high fee. While we are sure to already know the basic facts uncovered, we could help ensure balanced accuracy, including follow-on reporting,

    Yes, JohnO, these various market-oriented powerhouses naturally struggle to pick AWE winners in the early game, but they know the value of being early to "the biggest thing ever".

    Let's count Fraunhofer as the most technical player so far of the big analyists, and put Gerrad Hassan on a par with F&S, but also include Bloomberg and WSJ (Wall Street Journal). Then there are the direct institutional investors like SABIC and Mitsubitshi, who are making AWE picks, but narrowly and rather randomly. Google counts as a top AWE speculator, seeking to grow a winner in-house. Then there are various "small" entries by Royal Dutch Shell, BP, EU, US-DOE, and so on. Looming in the wings is Bill Gates, talking up AWE in public while waving two billion dollars that he does not not quite know just where to throw down. AWE's two dedicated investment funds, WoW and Daidalos, only recently were our top investors, are now tiny by the new comparisons.

    While the core winning AWE lineage is not yet obvious, the consistent signal from "Big Money" has become "Buy, Buy, Buy". Get ready for a very wild ride as the money floods in from all quarters in coming years, always recalling Corwin's lament, that too much money was the worst problem Makani faced. The preventative is to diversify AWE investment across all the strongest teams, and force them into a serious fly-off program.

    Subject: Makani's Ongoing Systems Engineering Challenge
    The AWES Forum has been Systems Engineering oriented from the start, treating all AWES architectures as contenders for comparative testing in a "knowledge quest", rather than making premature down-selects that are not data-driven.

    Google[x]/Makani's related AWES strategic-gap is publicly hinted deep within the flurry of new job listings, under Systems Engineer.  This lowly person, as judged by relative qualifications with other staff positions, must "develop and document architectural and trade decisions and derived requirement analysis". 

    This Systems Engineer is in theory charged with informing the program if the extremely complex and high-risk M600 system architecture is fatally flawed (as widely believed by AWE technical insiders), and how to address the problem by Google[x] rebooting into diversified AWES architectural research. The new hire will be under tremendous pressure to "validate" past assumptions, by ready circular-logic. We are watching high techno-drama, with monumental triumph or debacle looming.

    ------------------
    GoogleX Systems Engineer Responsibilities (from listing)-
    • "Develop requirements and specifications, validate requirements with stakeholders, and manage allocation of derived requirements to lower-level components and parts; Maintain configuration management of the requirements.
    • Collaborate with engineering to develop and document sub-system architecture.
    • Produce and maintain project data, planning, requirements, design, validation, verification and certification data.
    • Develop and document architectural and trade decisions and derived requirement analysis..."

    WindLift is now developing a 10kW kiteplane for remote markets. Joby motorgens are visible on a carbon winged platform reminiscent of Makani's Wing7. Apparently, WindLift is developing its niche product in the open gap Makani leaves behind by going toward larger scales. Note the NASA LaARC connection, suggesting the LaRC NI Labview-based vision tracking control system is the automation basis.

    Good to see Rob still at it, but the standing AWES question remains whether a complex kiteplane can safely survive to economic payback anytime soon-

    Subject: KiteMill featured in Norwegian energy magazine
    The beautiful sailplane airframes used for initial testing are now seen cluttered by a large avionics pod over the wing and two quad-rotor booms under the wing*. This is just how AE prototypes typically start dirty, and later must be cleaned up. In particular, an AWES kiteplane must avoid snagging its own line by hook-like features, just as traditional kite designers work hard to eliminate snags.


    -------------
    * The Whitcomb area-rule, where lateral cross-sections of the airframe are kept nearly constant by frontal area, is critical for transonic velocities, but is also valid for optimal performance at sub-mach velocities. Thus future KiteMill kiteplane design will likely shift payload volume forward from the wing location.

The following video features a history of cranes that move material and perform other actions; the video is not about AWES, but invites some further thinking about the AWES-based cranes of the coming future.

    Subject: Kite-Suspended Rope-Driving
    A basic challenge in rope-driving is to span long-distance without dragging on the ground. Cable car cables do drag in oiled trays, but with major trade-offs. The most common spanning solution is towers with rollers to suspend cable sections off the surface.* AlexB, in the modern open-AWE community, has advocated rope-driving suspended by kites, but we have yet to explore this design-space carefully.

    The simplest kite suspension of a drive-rope is done by a pulley or ring, often on a pendant , connected to the anchor-line. The faster the driven rope, the more power for a given load tension. If the rope experiences a load, the kite suspension accommodates by drawing down in proportion. This is a nice way to maintain overall tension within limits, by a "passive" embodied logic.

    Someday the transport cableway AlexB envisioned might become the preferred method to convey large-scale distributed AWE kinetic energy to centralized generator plants, with series of lifting kites instead of towers, for longer higher more-powerful rope-driving than anything before.
