AirborneWindEnergy: For More Power From On High (Luke1:3KJV)

60 Terawatt Unicorn- Upper Wind and Polymer Kite Networks (

Our entire civilization currently only draws ~20TW, but there is far power over our heads in the form of Upper Wind. Power kite networks accessing this power will usher in a new era of energy superabundance. The revolution has begun.

Future Global Energy Prosperity: The Terawatt Challenge

Richard E. Smalley 2004

“For accomplishing our energy goals, what we need to do is to find the “new oil”—a basis for energy prosperity in the 21st century that is as enabling as oil and gas have been for the past century. Innovations and advances in materials science (will) transform our vision of plentiful, low-cost energy into reality…developing new technologies…in the brave new energy era…everybody gets to play.”

Welcome to the forum John.

To complete your post, there are Advanced Kite Networks and Preprint on "Concept for the Giga-Wind Institute "Plan Humboldt" Chapter" topics.


Hello To John O., speaking for Dave S.: John, one of the hallmarks of wannabe wind energy efforts that go nowhere is to talk of the vast power available in the wind, as though such an observation confirms the notion that the method being promoted is automatically capable of economically extracting that immense power.
It is as though wind energy is not already an established art, and the promoter needs to convince an ignorant audience that wind energy is even worth pursuing. I see no evidence or indication that the Jalbert triangles of fabric are in any way relevant to wind energy, and we already know the promoter is against measuring output, but instead hopes people will just take his word for the idea that whatever his latest fixation is once again “the answer” to wind energy. Given the track record, I don;t think there is any real reason to take any of this seriously, but nice to see your smiling face here. :).

Wait a little longer, DOugS. It won’t be long anymore.

Thomas only needed a week’s wait to see the living proof he sought.

Higher heights,


Thanks, PierreB.
Glad to re-connect with you here.

Single-unit-kite concepts were not properly conceived to reach high altitudes. The proper way to fly highest is by multi-unit kite trains. The principle is precisely the same as multi-stage rocketry to achieve orbit; each stage carries the next higher.

Train Record 9740m 1919, over a century ago.

Lindenberg - historical world attitude record in 1919 (

For efficient Kite Trains today, we need to ask ourselves: who are current KiteMasters in our midst? This is where @Rodread and David Santos Gorrenna Guinn come to mind. Apart from being a veteran Aeronautic Roboticist with known connections in NASA; DaveS (USA) has had the honor to learn kite train practice by the greatest historians and practitioners of our time during a 7yr residency at the World Kite Museum (Patton, Diem, Busing, Hassan, etc.). He got to know Walter Diem, Germany’s greatest kite historian, at Fanø.

He affirms and I concur that: "Train topology was the standard method for scaling kites to altitude. Layered AWES can once again work at 10km, by the same principle-

One can scale horizontally as well with many-connected topological stability.

10km high? Of course, we can get there, harvesting AWE at every level in between. Our super-polymers are 10x lighter for the same strength than the piano wire that did it long before. Graphene will be 10x better still."
DaveS had always maintained from earliest Makani days that ‘Kite Trains’ is a critical AWE research direction being neglected by industry members, some of whom have burned through much investment (Makani, the lion’s share), but will never fly high, because they don’t practice multi-stage AWES.

Can sincere full disclosure of AWE R&D accidents show that no life has been lost to date in mishaps? More people may yet be saved in the course of AWE R&D through optimal research design.

My sincere appreciation goes to @Windy_Skies for this opportunity to rework my earlier version of this post.
Best lifts.

I am glad that the moderators have graciously agreed that this topic maintains its own thread. Please I welcome questions, ideas, and further contributions from all.
First, my sincere apologies for the seeming lack of focus on topic as pointed out to me already by @Windy_Skies.
My simple point from the earliest paragraphs is this:
‘Kite-Trains’ or ‘Multi-unit Kite Trains’ rather than single kites were the means by which the highest heights by kites were attained way back in 1919. It had also taken multi-stage rocketry with new propulsion taking the rockets from one height to the next at each stage for modern flights to achieve orbit. Should we not look into this in our AWE efforts? AWE is tethered aviation at its best.
If early Kite-trains with weightier tethers could reach ~ 10Km, can modern kite trains with much-improved technology and presumable stronger materials not repeat the same feat if we agree indeed that the higher winds are more powerful?
On my last paragraph: it is obvious that flight is risky and flight technology in AWE must seek to minimize risk. The risk increases in my opinion in direct proportion to the mass aloft hence the need for optimal research designs.

4879 m in 2014.

4422 m in 2000.

And as you indicate @AweEnthusiast, 9740 m in 1919, so more than twice the altitude reached by a single kite.

Indeed kite altitude is important for AWE, which intends to harness high altitude wind energy.

Always good to remember kite trains. I think we covered this quite a bit, circa 2009 - 2010.
SuperTurbine, Daisy, and stacks of kites, all exemplify this “stackable” paradigm.
Rather than more handwaving and happytalk about the vastness of the wind resource and stratospheric possibilities, while promising impending TeraWatts at some dubious future time, AWE seems to be in need of a cheap, powerful, reliable system at any scale (smaller is easier and more affordable), which could then be stacked, extrapolated, expanded, lengthened, multi-staged, etc. Just reminding us of the existence kite trains is good, lest people forget, but not really new information.

We are talking about several thousand meters of altitude where the resource is, and that the kites can reach, not a few meters above the ground.

For the moment Skysails seems to emerge clearly (100 kW average at hundreds meters height).

I think the questions or statements in this topic are too broad or too vague to be useful, and like Doug says in one of the moved comments, not necessary to build something now as you can always add stuff on later.

Narrower questions could be: let’s assume, or not, your kites are all mostly at the end of a very long tether as that is where supposedly the strongest winds are: how do you get the power to the ground? You’d choose one of several options and explore that further. How thick would tethers need to be, how long would they need to be, how heavy would they be and how much total drag would they generate, how much would that drag vary, what are the minimum and maximum wind speeds that the system could operate in, what would the cycle times be if there are cycles, how long would it take to launch and land, how would it launch and land, and so on ad infinitum.

I don’t think it’s safe to assume all kites follow classic rules. What kinda kite is going to be most altitude capable may require significant reconfiguration away from THE RULES.
This is a Daisy

A Daisy chain

These are not your typical diamond on a point at the end of a straight line kinda kites.
These are multiple kites at multiple altitude points up a line

Oh and these ones go sideways, huh look at that.

I have always been a bit perplexed by the lack of trains in AWE.

There is Zhonglu High Altitude Wind Power Technology - 中路高空风力发电技术, a train of parachute kites, which reached 512 m altitude.

An aligned (not crosswind) AWES like this, or a stationary AWES, would allow to mitigate tether drag which is seen as a limit for the reachable altitude of crosswind kites as specified on the video (from 0:43) of, but more details and calculations would tell the story better.

Ultimately, all questions cannot be answered here for individual understandings differ. Let interested parties ask their questions where they need further clarifications. Permit me to add though, that we may need the help of others not yet on the forum or perhaps already banned from the forum in the past to now answer some details.

No, it is unlikely that all questions will be answered in this topic, but over time a number of them may be become bounded by our greater understanding of conducted experiments, physics, and so on, which we can explore here. The rest of your comment is off topic here, so maybe you can edit that out before it derails the topic. You can put them here: Questions about Moderation - #42 by Windy_Skies

It is questions that form the basis of investigation. On the basis of those we can try to explore the topic further. What is a narrow question that you are interested in, so that we can undertake a more focused exploration?

There is more (Upper Wind) power directly above a nuclear power plant site than the plant itself generates.

Nuke 2km x 2km x 600m ft high = 1GW

2km wide x 1000W/m2 x 1km high = 2GW

Kite over Nuke

Online estimation not accounting for many cooling water features and extended security zones: “A nuclear energy facility has a small area footprint, requiring about 1.3 square miles per 1,000 megawatts of installed capacity. This figure is based on the median land area of the 59 nuclear plant sites in the United States.”

Elsewhere: “For example, according to the current version of the European Utilities Requirements (EUR), the nuclear power plant must be capable of daily load cycling operation between 50% and 100 % of its rated power, with a rate of change of the electric output of 3-5% of rated power per minute.”

JAL proposes aging Nuke Plants can derate and decommission by kite hybrid transition.

Oh, OK “Dave”. Sure, you’ve got all the answers. After all the big talk, when are we going to ever see you generate any significant power whatsoever? Haven’t you had that Jalbert apparatus for a few months now? When are you going to show the world how well it generates electricity? And meanwhile, how would you ever think you could drive a thousand-MegaWatt generator at a consistent grid-synchronized speed, with such an apparatus, as the wind alternates between stopped, reversing, fast, and slow, changing directions all day? Funny how consistently the people bragging about the most outrageous amounts of power “tomorrow” are the same people unable to generate any significant power at all, today, or yesterday, or the day before… and so on…
What is requi9red is consistent power output, not consistent idle over-the-top bragging-ahead-of-the-fact, and preposterous claims that are unlikely to be realized. I’d recommend you try for a consistent 100 Watts or so, and see if you can do that with your latest unwarranted fixation of “Jalbert”.

JAL: Power Kites are chosen to match wind conditions by Kitepros from a “quiver” of kites just as Sailors change sails or reef them to match conditions. Kites can be flown in different parts of the kite window to vary power. They can be “powered” or “depowered” by AoA control. Kites can be quickly popped up or killed. Kite Networks are especially flexible. Spidermills accept wind from any direction by bulk tilting faster than bulk rotation can adapt.

Mechanical transmissions can vary power by gearing and clutches. Flywheels and elastic response can smooth transients. A governor on the fossil or nuke side used to match load demand can also mix in kite power matched to demand. A flexible grid can do flex-work or bring storage up to regulate a grid. These methods taken together combine to promise concept feasibility.
