Subject: "Multiple Wing Systems- an Alternative to Upscaling ?" Moritz Diehl

Multiple Wing Systems- an Alternative to Upscaling ?   is an interesting topic covering also some other concerns as land use.


See some numbers taken (with simplified text) on video: "


2013 Ruiterkamp Sieberling Ampyx  3 m²  3kW average power   wind speed 13 m/s , i.e. 2,5% of potential.


2013 Vander Lind  4 m²  10 kw  wind speed 8 m/s, i.e. 25% of potential.


"major problem of single wing small scale systems: tether drag""


Concerning Ampyx plane 3 m² 3 kW (peak about 15 kW on curves) 2,5% of potential looks low. Perhaps recovery makes much drag.


Concerning tether, "tether drag" is seen as major problem": in my opinion it is right by considering performances of materials by themselves, and not right enough by considering performances by land and space used.

Bill Gates calls for Manhattan Project-style renewable energy drive

The world’s richest man said he planned to double his own investment in green technologies to nearly £1.3bn

Ian Johnston
Friday 26 June 2015
Governments should invest in research into renewable energy on the same scale as the Manhattan Project and the Apollo moon missions, Bill Gates has said as he revealed he planned to double his own investment in green technologies to nearly £1.3bn.
The world’s richest man told the Financial Times that he had invested $1bn (about £650m) in companies involved in carbon capture technologies, next-generation nuclear, new kinds of batteries and other types of research in the field. And he said: “Over the next five years, there’s a good chance that will double.”
Mr Gates, the founder of Microsoft, said “great innovation” was still needed to make energy in a way that would reduce carbon dioxide emissions significantly.
And this would only be achieved if governments spent tens of billions of dollars on research and development into new renewables, he said.
“Because there’s so much uncertainty and there are so many different paths, it should be like the Manhattan Project and the Apollo Project in the sense that the government should put in a serious amount of R&D,” he told the FT.
The Manhattan Project was the US research programme that led to the creation of the first nuclear bombs. It ultimately employed 130,000 people and cost more than $23bn in today’s prices.
But Mr Gates also suggested savvy private investors stood to make a fortune in the renewable industry in much the same way as those who picked the right firms at the dawn of the computer age.
“If I came and talked to you about software in the late 1970s, I would tell you: ‘Hey, somebody’s going to make a lot of money’. Now there’s a tonne of software companies whose names will never be remembered.… If you happened to pick Microsoft, Apple or Google, you would have made lots of money,” he said.
Mr Gates highlighted several areas of research that could prove promising, including technologies that would harness the power of the wind at altitudes of about 20,000 feet.
These could involve kites, kite-balloon hybrids known as kytoons or flying turbines capable of harnessing the energy of the jet stream.
“Capturing that energy is very difficult. It’s classic capitalism. There’s some wild-eyed companies, but it’s great. I wish governments would help those guys out because there’s a 10 per cent chance it’s the magic solution,” he said.
Another nascent technology to attract his attention is “solar chemical”, a kind of artificial photosynthesis that could be used to create hydrogen for fuel.
And Mr Gates has invested several hundred million dollar in “nuclear recycling”, which sees reactors powered by waste uranium from existing power plants as well as their own waste.
“Nuclear technology today is failing on cost, safety, proliferation, waste and fuel shortage, and so any technology that comes in has to have some answer to all of those things,” he said.

Subject: Twisted v. Braided Rope (practical and theoretic aspects)
kPowers first iso-dome is made from "crab rope", a cheap polymer three-strand twisted line with good commercial work performance. A traditional fisherman mentor showed me the pro tips to spicing this stuff for aerotecture experiments (its very stiff compared to classic manila). He warned that the inherent twist, which varies with tension, might affect kite operations, depending on the situation. Twist is also a major consideration with wire rope in situations like mine elevators. A torsion balance based on twisted fiber is the most sensitive mechanical instrument known. Siesometers based on torsion balance detect small quakes at great distances. Braided rope cancels twist by two-way crossings of the strands.

Sure enough, at the Texas AWE Encampment on Mustang Island, the twisted rope segments proved unsuited as leaders for the pilot kites, even with swivels, since even the small torsion force of the swivel ground-state is enough to cause the kite to lean considerably. The twist would even migrate far up the bridle, such that a spreader rigging-plate would be needed. Braided rope is clearly favored for kite leaders, since the kite is a sensitive dynamical system. On the other hand, the strong cheaper twisted rope worked just fine to assemble the lattice itself, since the junctions are comparably insensitive to torsion. 

There is deep fundamental physics at work here. Key concepts include dynamic tensile forces with order, entropy, symmetry-breaking (spin, handedness), braiding statistics, and so on. The most advanced String Theories are crude analogs of our real strings, which are full of useful tricks for those skilled in traditional rigging arts.

Subject: Re: Fw: BIll Gates asks governments to support High Altitude Wind En
Here's the original Financial Times version, with the relevant text quoted-

 

"High-altitude wind power was the third and most exotic-sounding potential technology. It would harness the kinetic energy of kites, “kytoons” — or kite balloons — and even flying turbines, tied to the ground by a system of cables and tethers.

This would tap into the energy of the jet stream that circles the planet at altitudes of 20,000 feet. “Capturing that energy is very difficult,” Mr Gates said. “It’s classic capitalism. There’s some wild-eyed companies, but it’s great. I wish governments would help those guys out because there’s a 10 per cent chance it’s the magic solution.”

Subject: Re: Twisted v. Braided Rope (practical and theoretic aspects)
To cancel twist with twisted rope requires both right- and left-handed lays. It used to be common to be able to choose which lay, but not so common anymore as braided rope became standard. Ropemakers make rope to whatever spec required, but not at the same bargain pricing of mass-market rope. Its not too complex to twist one's own rope in need, like when a strong rope is wanted, with only cord at hand.

Energy briefly stored in twisted rope can help sustain passive cycling of kinetic and potential energy in an AWES.

Subject: Extension Cord into the Sky
Yesterday, in light wind, at the Texas AWE Encampment (Austin), kPower flew an extended COTS electrical cord to about 60ft high.(100ft, 14 gauge, three copper conductor, 12USD) to about 50ft high, under a 9m2 pilot kite. This dummy-mode operational experiment showed how easy and practical it is to create a self-lifting electrical conductor rated at a few kW. Power can run up or down between applications including bulk collections of load or generation devices at either end (like surface solar power to kite). Distributed lift for distributed small harmless payloads aloft is intended to be a safer design strategy than creating larger unit-mass components.

Hoists in AWES

We have already considered the large space of using AWES as lifting workers; keeping that as a separate topic, this present topic faces secondary hoisting in AWES. Hoisting aerially or at anchor and ground stations using non-kite hoists will have plays in AWE. The secondary hoists may be held aloft by primary AWES or may operate to serve AWES.  And we separate herein the primary winches that may operate main or secondary or tertiary tethers involved in the flying of wings.

Subject: Current Status of AWEC, NTS, and SkyWindpower?
Strange bits of news from the conference proceedings. According to TUDelft's latest world map of AWE companies and schools, NTS and Sky WindPower, key former AWEC movers, are defunct*. Chris Vermillion proposes a renewal of AWEC, but as a North American consortium under academic norms to match HWN500-AWESCO. This would once again leave the global AWE organization space to AWEIA (the oldest industry association player); plus the Kite Power Cooperative.

* Magenn and a couple less known names are also crossed out, but there are several new entrants for every supposed drop-out. Any of the down companies could resurrect in a hot AWE market, from considerable residual value in people,  tools, prototypes, IP, etc..

Roland projected the updated world map during his presentation, with AWESO partners highlighted, but several companies crossed out, as the unintended shocker.  The map is known for gaps and errors (like kPower's name wrong for years now), so we have to fact-check, but at least we are getting rare inside news from the  AWE-elite insider world. There are a few more dramatic developments to report from conference proceedings that come as brief flashes in an otherwise rather boring repetitive content. Curran Crawford, et al's AWES scaling analysis (University of Victoria, Canada) between soft kites, gliders, and turbines-on-a-wing is even more disruptive than corporate melodrama, but comes in the same short flashes within a general conference dullness, but will get its own topic.

Subject: kPower tests Negative-Lift Flygen KitePlane at Texas AWE Encampment
Today we flew the 2m WS RC glider with a Pacific SkyPower turbine mounted, under a 9m2 PL pilot-kite. It swept manually under good control-authority, and also by passive-autonomy; safe from crashing. The method is a robust solution for high-risk architectures like Makani and Ampyx. Negative-lift refers to the kiteplane on average pulling downwards. The wing is thus mounted upside-down. It cannot crash as long as the lifter's own positive-lift is greater. Launching and landing is done by raising and lowering the kiteplane by a halyard (pulley). This is also seen as a lattice-array unit tech, toward interconnected many-wing units. Video soon. This was just the first flight test, to confirm flyability, with data-logging power-curves to follow.

    Subject: Design soft kite backward from desired flow change
    Given a flowing volume of wind field. Given what we know about kite characteristics.
    We can work toward creating a specified disruption to that field.

    From the model of desired change there will be a specific energy change and material placement need.

    e.g. To adjust the whole flow left. A vertical curtain / vane whose upwind is right of it's downwind is the specific material placement need.
    Bit too simple though... drag, gravity and vane deflection all need considered.
    All kite skins have drag in a flow causing localised turbulence. Webs along the flow direction help to alleviate flow mixing and keep our sheet aligned to windward.
    Our sheet isn't infinitely stiff, the whole sheet of vane is deflected with a pressure profile, we use spread bridling on the webs to hold our kite in a C shape. We don't have a crane above our kite so we need to use some of the flow energy to counter gravity on our kite.

    Now say we specify a vortex as the desired shaping change to the flow.
    We can use the implied energy change to parametrically specify a circular (or course adaptive circular) array of foils suitable to the desired vortex energy change?

    Just as parachute companies fulfil orders based on payload weight and height of drop with a specific catalogue model ready to make.
    AWE is working toward being just as ready for deployment.
    Parachute companies had to drop a load of broken crates before they could be so specific. Maybe we can be more adaptive with custom machined individual kites of recorded parametric sold but still returning data to our evolving design model.

    This difference between it's pretence as an industry association and it's real intent and practice has been the reason for AWEC's continued hostility to Airborne Wind Energy Industry Association AWEIA - the one global AWE VOICE from conception in 2009 till date.

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

    Consider all scales, niches, and applications of AWES in the study of spooling lines. Note: Spooling is not the only way to gather line; the non-spooling line gathering and handling may be considered in other topic threads.


    Spooling studies will involve spools, drums, sheaves, reels, grooves, safety, use fit, COTS, experiences, power, wear, inspection, sensors, pressures, tensions, and more. Errors in spooling may close an AWES operation. Spooling engineers and spooling specifications will play roles in AWE.

    In principle, one can use a second kite in another part of the wider flow field to brace the kite that cancels the tornadic rotation. Small influences might cancel a tornado, if enough is known about the dynamical state.

    The practical problem is predicting when a tornado will rampage at any given place, with only once chance in many thousand that it will occur at any given place on a given day. A fixed system in Tornado Alley would wait about 3000yrs, on average, and chasing tornados is very unreliable.

    A simple benchtop test would be to cancel vortices in water with tethered paravane pairs.

    Subject: UAV uses and folding boom props (RAT in a cage) at daisy driver root
    I was playing with a drone last night. It got me thinking...

    First: Auto grab launch and recovery adaptations... There was a go-pro attached to the drone on an auto steadying powered gimbal. Underneath the camera there is still ~20mm space above ground when landed... Just enough space to mount a small boom threader (like Hook and Moor by ROBship)
    The existing drone software can fly to coordinates ... go to where the kite has landed.
    Once at the kite site we want to locate and grab something.
    A painted net bag drogue (like a midge head net) tethered to the top of the lift kite..
    Or maybe a ring on a line or a ring on the lift kite or a ring half way on the drogue bag line.... Well with the lance in the field of view ... we just have to align the UAV on the target and approach to match the target to a known size in the field of view of the go-pro to know when we are at the correct distance to grab.
    We have recognition code freely available. Do we need an additional microcontroller? or can it all stack on top of the already FOSS UAV code?

    Massive (over 1km) kites will be alive with software. Otherwise I suggest they will be practically unmanageable.

    Second: Retractable props. If we thrust a boom prop up and down inside a cuff we can unfold and fix the blades for both lift mode and gen mode by guiding the blades from the cuff. So where twing (I think it was) suggested they are adding 3 blades to their design for VTOL... fine but tuck them away out of the flow for utility kite gen mode.
    The stl (3D) files and video instructions for making a UAV folding boom prop
    can be found here...   https://www.youtube.com/watch?v=kmxpGFzMaKY

    With that idea in mind & I'm thinking of ways of making HARD/SOFT Daisy devices. A RAT available to deploy from a pod at the root of a Daisy driving kite... hmmm tempting but for now I can still get pressure I want from foiling...
    Inflating sheets can get you a good L/D=10 wing... so maybe this method where the ring gathers pressure would help... https://youtu.be/nMk7uLACDck (the vid shows single skin...This kinda closing cell parafoil is more likely to be easily inflated and it's just amazing to see)

    A RAT in a Daisy root may not be out of scale if the Daisy ring gets beyond say ~15m dia. At that size Auto furling (either tip or root first) looks feasible. There will of course be an upper limit to direct scaling of hard components. Ways to autofurl include using slapwatch / flattens style battens in the leading edge... or bike cable, or maybe fancifully an inverted cuffed silicone filled tube pusher.. sprung edge, ....other suggestions welcome.

    Otherwise no news.....been desperate to get out and test my 2 ring stack for ages now... Soooooo many things getting in the way of progress.
    Pleeeeeeaaaasssssee somebody else do this or employ me to.
    I am a bit concerned of the ethical standpoint of the academics I try to ask about rotary kite ring systems... They answer self interested concerns but seem unable to admit the existence of a Daisy style kite or isotropic kite mesh system. I'm going to blow a fuse if that doesn't resolve. Not pretty.

    Launch the kiteplane in system as noted.

    But consider landing the kiteplane by release of the kiteplane's wing from the mother system for a free-flight homing glide to base. This might be done to avoid challenges of system or weather or wind or time constraints; but it may also be considered for repair, aloft-charged battery landing, making room for another kiteplane ... all while lifter wing set remains up flying.

    To get around the statistic 3000-year challenge, consider dome-mesh AWES where sensors in the mesh tell of ripening tornados; then the dome mesh of kites robotic respond to set wings to give anti-sense vortices. The broad dome AWES farms could communicate with each other and provide broad response. Meanwhile, the peoples would be gaining power from the dome AWES.  Spot shading for labor and production could occur in the dome meshes by order.

    Subject: Weather Control by Kite Lattices
    This is a more general new topic than attenuating or snuffing tornadoes and hurricanes by locally-based kite systems.

    Joe is stating that a comprehensive kite "dome mesh" (airborne latticework) on a regional or planetary scale can in principle control peak weather events and climate by dynamical interactions with sensitive conditions.  Also new here is that such lattices can also provide required real-time sensor data. These capabilities are beyond just generating abundant clean energy. Airborne latticework can support all kinds of apps, like aerotecture. Kite lattices an incredibly powerful technology to be urgently but wisely applied.

      Subject: Water Evaporation in AWES

      Water Evaporation in AWES 

      The few mentions of using water in AWES just scratches the surface of a tech body that may well grow ever more meaningful; putting out fires, using wet wicks for sensors and controls, giving potable water where needed, collecting water from the atmosphere only to move it to air and ground uses, misting to lower temperatures over people and crops, making ice for food/medicine preservation, recharging dams for hydroelectric purposes, and more.    I add some additional attention on evaporation of water as worker in some AWES. When evaporation of water is used in an effective AWES, such extends the kPower portfolio on such; anyone's extension of such tech is invited to add their notes and experience in this topic thread.


      Using the distillation potential of salt water or grey water is included in the portfolio.

      Using the cooling effect of evaporating water is included.

      Using the mass transfer by way of evaporation of water is encircled by the focus here.

      Using the wetting of tertiary matter including biological matter, even live spores, plants, or animals is involved.

      PS: Look also to sublimation of carbon dioxide dry ice and other similar materials and processes where sublimation or evaporation occurs.

      That video is so nerdy that it's cool.
      I'm sure we could aim some kite mirror at one side of the wheel part and duct some wet air to another.
      How's about get the water muscle to reset our kite suitably for inherent water relaunching?
