Please see the communication problem here, that no one in the world seems to understand your extraordinary claims properly, so you get countless "nonsense" reactions. A working proof-of-concept prototype doing what you claim would cut through the "nonsense". You seem to be claiming theoretic breakthroughs that are somehow impossible to hack, which seems "nonsensical".

After all, proto-humans tested fire before "understanding (a) theory" of oxidation, nor did diligent boomerang or kite testing wait for aerospace science. That engineering testing is most productive starting from partial understanding is common sense, not "nonsense". Will we ever see your ideas in flight?

On ‎Tuesday‎, ‎May‎ ‎23‎, ‎2017‎ ‎04‎:‎46‎:‎54‎ ‎PM‎ ‎CDT, 'Peter A. Sharp' sharpencil@sbcglobal.net [AirborneWindEnergy] <AirborneWindEnergy@yahoogroups.com  

Hi DaveS,

You said about the Sharp Intermeshing VAWT concept:

"It seems as if the intermeshed VAWT pair depicted has the same overall solidity, rather than a true doubling of downwind solidity."

Nonsense. You are measuring the solidity ratio of the intermeshing middle section incorrectly. State your method and your calculations.

The solidity ratio of the intermeshing middle section is the sum of the separate solidity ratios. So if the separate rotors have a solidity ratio of 0.2, the intermeshing middle section will have a solidity ratio of 0.2 plus 0.2 equals 0.4.

The optimum solidity ratio of the original two rotors might be more like 0.15 so as to insure that the operating tip speed ratio of the Intermeshing VAWT stayed above 3.0.

 

" In any case, no VAWT blade aligned in upwind or downwind phases is helping, but adding drag."

Nonsense. “Phase” in this context refers to 180 azimuth angle degrees of blade travel, either to windward or to leeward. Lift-type VAWT blades, due to their circular orbit, are always traveling either to windward or to leeward -- except for the very brief transition points at the most-upwind and most-downwind points. So your statement claims that no lift-type VAWT blades can convert any energy -- except at the two very brief points where the blades are moving directly across the wind. But obviously, they do.

When VAWT blades are briefly heading directly upwind or downwind, they do create only drag and no lift. That is obvious. But the losses due to that drag are typically small for a well-designed VAWT with good streamlining. Consider this analogous flawed-argument: The solidity ratio of the HAWT blades near the hub is typically far too low to be efficient, so HAWT are inefficient. The premise is true, but the conclusion is not. That is because the losses near the hub are minor as compared to the major gains near the blade tips, due to the very large difference in swept area. You are incorrectly assuming that a minor disadvantage of VAWT is a major disadvantage of VAWT.

 

"Differing predictions that this is the "most efficient wind turbine" or that a parasitic VAWT drag factor reduces power-to-weight, compared to a HAWT rotor, awaits testing."

Nonsense. There are no “differing predictions”. If you insist that there are, then identify them and cite your references. As yet, there is only my prediction. If you wish to present a differing prediction for a Sharp Intermeshing VAWT, then please do so, along with your supporting reasoning and calculations.

Your statement is based on an illogical argument, which is this: Because most VAWT have more sources of drag than HAWT, and that because most VAWT rotors weigh more than most HAWT rotors, therefore VAWT cannot achieve a higher coefficient of performance than HAWT. That is like saying that because women are, on average, smaller and slower than men; therefore women are not able to bear children better than men. Women have characteristics that men do not have. VAWT have characteristics that HAWT do not have. Your false conclusion does not follow from your true premises. The VAWT disadvantages simply do not preclude VAWT from converting more energy than HAWT. If you insist that they do, then please present your reasoning in detail and cite your evidence.

New VAWT advantages continue to emerge. Intermeshing may be a new one. Those VAWT advantages can be translated into higher performance than HAWT. That is in spite of the disadvantages that most VAWT have. The advantages that VAWT have over HAWT could be stated negatively as the inherent disadvantages, faults, or limitations of HAWT. There are many. Can you list them? If not, then that would suggest that you have not evaluated the differences between VAWT and HAWT impartially.

You call for the testing of my theoretical prediction. But that is what theoretical predictions are for…!? So your recommendation is redundant. That is like telling someone who has written a shopping list that they should go to the store.

I have noticed that you immediately call for testing concepts or devices I present when you don’t understand them. But if you don’t understand what is being tested, you won’t be able to interpret the test results. For example, assume two Sharp VAWT (Cp = 0.45) are combined to create an Intermeshing VAWT with a predicted Cp of 0.60. Testing determines that the Cp is 0.50. Is my hypothesis supported, unsupported, or indeterminate? Explain your decision.

Your immediate call for testing implies that you assume that theory has little value until tested. Theory and testing are two sides of the same inseparable, scientific coin. Both are equally valuable and mutually indispensable. Without theory (specifically, an hypothesis, which is a prediction based on a theory), there is nothing to test. Theories also serve to provoke refinements or replacements of themselves. In other words, they raise new questions and possibilities, and they encourage skepticism about existing assumptions. In science, that is valuable, even without testing.

Most likely, the next step in evaluating an Intermeshing VAWT would be to run a simulation using intermeshing fixed-blade VAWT for simplicity. That is because Sharp VAWT are extremely difficult, and extremely expensive, to simulate due to their passive pitching. Then a wind tunnel test using fixed-blade VAWT models could be done to confirm the simulation if it produced sufficiently positive results. However, the extra width of an Intermeshing VAWT might preclude wind tunnel testing due to anticipated blockage effects. Testing wind turbines can be a lot more difficult than most people realize. And it can be quite expensive. Even simulations can be quite expensive. So going directly from theory to physical testing is seldom a practical strategy. In other words, to immediately call for (physical) testing is usually naive. And to call for testing before even understanding the theory to be tested is nonsensical.

Subject: Re: "Rapid" in RAD?
I don't think any of us needs to see a dictionary entry for "rapid".  I think we all know it means "fast", "quick", "without delay", "taking less time than one might expect", etc.  Not a difficult concept.  Probably a second-grade vocabulary word. 

The question I'm trying to get to is, what does "rapid" mean in the context of "Rapid Airborne Wind Energy Development"?  For example, if we had discussed this at the first High Altitude Wind Energy Conference in 2009, what year would we have said there would be systems in regular use?  Maybe 2012?  2013?  Certainly by 2014, with half-a decade having passed, any semblance of "rapid" development would seem to have evaporated.  How many years would we have agreed, in 2009, would have passed before there ought to be at least one AWE effort putting power to the grid?  Five years?  Ten?  I don't think ten years was envisaged.  I think, now that so many years have gone by, the term "rapid" is losing any meaning, in discussing AWE. 

Let's keep in mind, during that long-past era, Magenn was providing the most highly-promoted image of AWE (seems like a million years ago, not to mention I think everyone sees now that it was ridiculous the whole time), so I guess we were all waiting for Magenn spinning blimps to lower the cost, and increase the amount, of wind energy, until at some point... we weren't.  Is this "rapid"?

I don't remember any specific point in time when it was officially decided that Magenn was a bad idea the whole time, but nowadays I do not see anyone promoting the spinning blimp idea for wind energy.  But, if Magenn HAD been a good idea, and if they HAD started building lots of them and within, say, a couple of years Magenn systems were putting power to the grid, that would have been "rapid". 

But the only problem seems to be the lack of anything that works well enough to be useful.  Magenn is not going to multiply in large numbers if it doesn't produce significant electricity, for example.  Anyway, my point is to just "say" the word "rapid" or to try and say you are operating under such a condition as "rapid", seems quite meaningless if, after ten years, there is still nothing running. 

So my take is that nobody has defined numerically what "rapid" means in this AWE-Development context, so I submit that the term "rapid" is meaningless within this context.  You could just as easily say "slow" and be just as accurate, or maybe more accurate, or just not mention a timeline at all. 

It reminds me of someone with a super-super-super-messy house, just filthy with crap everywhere, and the owner keeps repeating "rapid super-immaculate housekeeping, rapid super-immaculate housekeeping."  At some point, you might tap the guy on the shoulder and ask "What are you talking about?  Why do you keep saying that?"

Subject: Re: "Rapid" in RAD?
OK so you are now changing the word "rapid" from meaning "fast" to meaning "lots of people trying it"?  Not buying it.  Do you remember how, years ago, I compared the high number of "teams" attempting kite-reeling as being similar to other situations where, say "millions of flies" were attracted to something, but that didn't necessarily make it good?

Let's be honest.  You provided a dictionary definition of "rapid" and I do not think it included "a large number of people trying something".  It would be refreshing if you would admit that things are not progressing rapidly after all.  I think the real motivation for that word is to pave the way for a VERY stretched acronym of "RAD" that makes everything sound, well, you know, cool, hip, all that jazz.  I mean, you could probably come up with a great acronym for "Mundane" but that doesn't sound "hip".  That sounds more like what wind energy really is after you get used to it - kind of boring but not as boring as solar, which is about as boring as it gets until you get the check from the electric company. 

Anyway, if the acronym-attempt turns out to be inaccurate, then I think it should be dropped.  And no, I do not think a series of attempts to re-define what the word "rapid" means (moving the goalpost) are going to fly, so I'd forget about that approach - you have already provided a dictionary definition.  Rapid means fast, and Airborne Wind Energy has not developed fast.  Rather it turns out to be a bigger challenge than most assumed, and is taking a long time, if ever.  It may even be in reverse right now.  I saw a lot more confidence of "impending success" a few years ago than I do now.  Now it seems to be turning into work nobody wants to bother doing, like laddermill, just "too hard".

***Which is what I said from the beginning.  And of course get no credit for it then, or now.  How many times did I predict the Hawaii [[Makani Power]] and Alaska projects [[Altaeros]] were never going to happen?  Yes, I had a pretty good laugh over that one.  But while I was laughing, so many others kept talking about Alaska and Hawaii as though they were really happening.  Funny.

Planning to deploy in a remote place "because the price of fuel is high there is part of the never-ending syndrome.  They don't take into account that the same factors that make fuel so expensive there will make an R&D effort too difficult  They "think" (without really thinking it through) proximity to high fuel costs in testing (somehow) improves the data of the prototype enough to make it worth testing in a place where they cannot get to easily.   Why do they think this?  Because without any real experience in wind energy, they think their machine will run perfectly the first time and not need any rebuilds, changes, adjustments, etc.   They think they will get it right the first try, even including response to storms and strong winds.  Well of course that is delusional.  High fuel prices near the point of deployment do not make your wind system more powerful or more reliable.  The two are not connected in prototype testing.  So it never made any sense, except if they thought their prototype was a production version.  Like it was already perfected.  That's delusional.  Nothing that new and different works perfectly the first try.  So now they saw some reality - test where you can work easily and get supplies and materials and machining done, where the weather is accommodating, In other words have some common sense instead of being in a gleeful dream-state based on green-energy truisms and platitudes and how many group selfies you can take.

DougS: remarks:
*** I think they're the only ones, rather than a "leader" per se.  They will be a "leader" if anyone follows them as we saw with kite-reeling - many teams trying the same approach.

 At this point I'd say they are on their way to either get this idea going, or struggle with it and not have it go into regular operation, or not be developed further.  After that it may be that other tidal approaches do better, and this approach may be abandoned. 

So, while I don't see any reason it should not work, I can also imagine there might be some reasons I'm not seeing.  I would not get quite so certain about this catching on, until we know more.  It may work great or it may be "more of the same"... 

Look at Sky Windpower.  I was not able to see a flaw in that approach, and still don't, but it never seems to get developed.  So this may turn out to be like that.  We will not know until we see more.  And even then, it's hard to say whether the theory was lacking, or if the implementation just needed improvement..

"Note that drive-loop AWES like these do not just pull themselves down, as Doug predicted, but run quite well as long as the load-motion force is less than total tension."

DougS remarks: 
*** I did not "predict" they "would" pull themselves down.  I "noted" that they would "tend" to pull themselves down, since they can only transmit power down, in proportion to how hard they pull themselves down.  So sure, they can overcome this downward pull by adding more kite to compensate for it, but that does not negate the fact that the downward pull is real, is a negative factor for this approach, and must be taken into account with something to counter it, such as a larger kite.

Subject: Re: Sharp Intermeshing VAWT; Sharp VAWT with Flyball Governor; Sharp
Peter,
      With regard to your vertical axis designs, observations, and claims, I remark:
With all due respect I have to say some of your statements are maybe not quite as nonsensical as we do often see in "AWE", but also maybe not quite 100% accurate.  For example you often talk about a tilted VAWT with short blades compared to diameter being able to intercept more area than if it were flat, as though it is unique and as though it has no downsides.  Increasing swept area by tilting it may be true, but this configuration would still be judged and rated on its intercepted area when tilted. 

The factors you do not mention:
1)  Twice the tip-losses because each "short" blade has two ends (two sources of tip-losses), and that becomes more important because of the short blades, and
2)  You could remove the blades of any such vertical-axis turbine and throw them in the dumpster, then apply airfoils to the arms that held the blades, turn the whole thing 90 degrees, and make more power than the original vertical-axis machine.  V-A machines have quite a history: They seldom, if ever, work out, for many very good reasons, most of which I'm pretty sure you are aware of, but maybe tend to overlook when promoting V-A machines..

Also:  I can do a similar trick with a HAWT:  It's called SuperTurbine(R) (as you know) and it also multiplies swept area without increasing diameter, by tilting the machine so the wind can reach the downwind blades, except in the case of SuperT there is no finite upper limit to the amount of increase in swept area.  The 3-foot-diameter Popular Science Invention of the Year turbine incorporated a 2-or 3- kW generator (can't read the label anymore - it got damaged) using 25 rotors.  Note: any previous stories of it not having a generator are inaccurate, since the generator is integral to the structure of the machine as a whole, the photos clearly show the watermelon-sized generator, and it is still out in my garage, available for inspection.  Dang, I always wanna run it, but I have a SuperTwin(TM) mounted on that van right now, helping to pay our electric bill.

OK so you are now changing the word "rapid" from meaning "fast" to meaning "lots of people trying it"?  Not buying it.  Do you remember how, years ago, I compared the high number of "teams" attempting kite-reeling as being similar to other situations where, say "millions of flies" were attracted to something, but that didn't necessarily make it good?

Let's be honest.  You provided a dictionary definition of "rapid" and I do not think it included "a large number of people trying something".  It would be refreshing if you would admit that things are not progressing rapidly after all.  I think the real motivation for that word is to pave the way for a VERY stretched acronym of "RAD" that makes everything sound, well, you know, cool, hip, all that jazz.  I mean, you could probably come up with a great acronym for "Mundane" but that doesn't sound "hip".  That sounds more like what wind energy really is after you get used to it - kind of boring but not as boring as solar, which is about as boring as it gets until you get the check from the electric company. 

Anyway, if the acronym-attempt turns out to be inaccurate, then I think it should be dropped.  And no, I do not think a series of attempts to re-define what the word "rapid" means (moving the goalpost) are going to fly, so I'd forget about that approach - you have already provided a dictionary definition.  Rapid means fast, and Airborne Wind Energy has not developed fast.  Rather it turns out to be a bigger challenge than most assumed, and is taking a long time, if ever.  It may even be in reverse right now.  I saw a lot more confidence of "impending success" a few years ago than I do now.  Now it seems to be turning into work nobody wants to bother doing, like laddermill, just "too hard".

*** I think they're the only ones, rather than a "leader" per se.  They will be a "leader" if anyone follows them as we saw with kite-reeling - many teams trying the same approach.

 At this point I'd say they are on their way to either get this idea going, or struggle with it and not have it go into regular operation, or not be developed further.  After that it may be that other tidal approaches do better, and this approach may be abandoned. 

So, while I don't see any reason it should not work, I can also imagine there might be some reasons I'm not seeing.  I would not get quite so certain about this catching on, until we know more.  It may work great or it may be "more of the same"... 

Look at Sky Windpower.  I was not able to see a flaw in that approach, and still don't, but it never seems to get developed.  So this may turn out to be like that.  We will not know until we see more.  And even then, it's hard to say whether the theory was lacking, or if the implementation just needed improvement..

Doug is mistaken to define the SuperTurbine(R) as a HAWT. To the degree that it aims upwards, it does not have a horizontal axis.

Peter,
      With regard to your vertical axis designs, observations, and claims, I remark:
With all due respect I have to say some of your statements are maybe not quite as nonsensical as we do often see in "AWE", but also maybe not quite 100% accurate.  For example you often talk about a tilted VAWT with short blades compared to diameter being able to intercept more area than if it were flat, as though it is unique and as though it has no downsides.  Increasing swept area by tilting it may be true, but this configuration would still be judged and rated on its intercepted area when tilted. 

The factors you do not mention:
1)  Twice the tip-losses because each "short" blade has two ends (two sources of tip-losses), and that becomes more important because of the short blades, and
2)  You could remove the blades of any such vertical-axis turbine and throw them in the dumpster, then apply airfoils to the arms that held the blades, turn the whole thing 90 degrees, and make more power than the original vertical-axis machine.  V-A machines have quite a history: They seldom, if ever, work out, for many very good reasons, most of which I'm pretty sure you are aware of, but maybe tend to overlook when promoting V-A machines..

Also:  I can do a similar trick with a HAWT:  It's called SuperTurbine(R) (as you know) and it also multiplies swept area without increasing diameter, by tilting the machine so the wind can reach the downwind blades, except in the case of SuperT there is no finite upper limit to the amount of increase in swept area.  The 3-foot-diameter Popular Science Invention of the Year turbine incorporated a 2-or 3- kW generator (can't read the label anymore - it got damaged) using 25 rotors.  Note: any previous stories of it not having a generator are inaccurate, since the generator is integral to the structure of the machine as a whole, the photos clearly show the watermelon-sized generator, and it is still out in my garage, available for inspection.  Dang, I always wanna run it, but I have a SuperTwin(TM) mounted on that van right now, helping to pay our electric bill.

Doug's predictions about loop drives being pulled down unduly are best judged as archived. The same principle applies to the ST, which requires extra lift to maintain tension against drive-shaft buckling.

The advantage of a string loop over a drive-shaft is robust low-mass and low-cost. Even more kite-lift is needed for a drive-shaft, which has a lower power-to-weight potential than the contending methods, under engineering scaling laws.

Doug is correct to agree that remote testing in Alaska, Hawaii, Australia, and so on, is a burden on RAD. The supply-line principle is well known, and well covered case-by-case on the AWES Forum.

Were Doug departs from agreement is in not testing often and relentlessly, local or not. USWindLabs seems to complain the most and test the least of any current AWE player. Right or wrong, guessing about Altaeros does not make up for the long stoppage of ST testing.

***Which is what I said from the beginning.  And of course get no credit for it then, or now.  How many times did I predict the Hawaii [[Makani Power]] and Alaska projects [[Altaeros]] were never going to happen?  Yes, I had a pretty good laugh over that one.  But while I was laughing, so many others kept talking about Alaska and Hawaii as though they were really happening.  Funny.

Planning to deploy in a remote place "because the price of fuel is high there is part of the never-ending syndrome.  They don't take into account that the same factors that make fuel so expensive there will make an R&D effort too difficult  They "think" (without really thinking it through) proximity to high fuel costs in testing (somehow) improves the data of the prototype enough to make it worth testing in a place where they cannot get to easily.   Why do they think this?  Because without any real experience in wind energy, they think their machine will run perfectly the first time and not need any rebuilds, changes, adjustments, etc.   They think they will get it right the first try, even including response to storms and strong winds.  Well of course that is delusional.  High fuel prices near the point of deployment do not make your wind system more powerful or more reliable.  The two are not connected in prototype testing.  So it never made any sense, except if they thought their prototype was a production version.  Like it was already perfected.  That's delusional.  Nothing that new and different works perfectly the first try.  So now they saw some reality - test where you can work easily and get supplies and materials and machining done, where the weather is accommodating, In other words have some common sense instead of being in a gleeful dream-state based on green-energy truisms and platitudes and how many group selfies you can take.

Pierre overlooks that Doug has indeed called his non-horizontal tilted-axis AWES concept a "Super Turbine" on countless occasions.

If a near-surface HAWT axis were extended to reach upper wind, only favorable terrain or the curvature of the Earth would allow it to finally reach upper wind.

*** I do not believe I said anything about loop drives being pulled down "unduly".  That is putting words in my mouth.  I said they are pulled down in proportion to how much power they make, and that the downward pull would have to be taken into account and accommodated, by, for example, using a larger kite. 

I said I think it is an idea worth pursuing, one of the many, and also please realize my original AWE idea, later called "laddermill", is also a loop drive, so a loop drive was my first AWE idea, and so I am certainly not against the idea at all, but rather simply pointed out a detractive factor regarding this method of getting power to the ground that many people may not have noticed.

Any claim of a SuperTurbine(R) suffering from tether pull-down should be taken with a grain of salt.  The armchair theoreticians have scant understanding of the true dynamics of SuperTurbine(R).  I don't talk about them, and nothing I have ever read or heard indicates to me that anyone else has ever even considered them.  They are not obvious.

Note dates of links: 

​Which of the 97 applicant teams use the kiting principle? How? Details?
Which, if any, are in the selected 20?    

Then, the question: did the winner AquaHarmonics use any kiting principle?   Wednesday, November 16, 2016

============================== ========================
"The 20 qualified teams, selected from the field of 92 official registered teams announced on July 6, will continue their quest to double the energy captured from ocean waves and win a prize purse totaling more than $2 million."​

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

"An 18-month design-build-test competition, the Wave Energy Prize focuses on catalyzing the development of game-changing wave energy converters that will ultimately reduce the cost of wave energy."
============================== ===================

And finally, what are some wave-energy kiting-based arrangements that may have been missed by the 97 teams that had applied for the concluded project.   
     It will take some time to carve out on-topic answers, as the finding of answers over the 97 team proposals may be difficult to obtain. 
============================== =====================

We have some notes in forum on kiting principles in some wave-energy schemes. But the realm surely is not exhausted. History, contemporary studies, and movement to the future will provide some kiting-principle wave-energy AWES. Some of the AWES will be fully paravane, but some will share the three media: soil, water, and air. 
============================== ====================
In the wave-energy converter circles "WEC" relates to "wave-energy" conversion. Air-realm wind readers use "WEC" as wind-energy converter. 
============================== =====================
Along the study in topic, what lessons might be available for AWES
and RAD from the concluded contest?   Will there be a similar contest for AWE?

Subject: Re: Wave-Energy and Kite Principle
I would not expect any wave powered energy capture apparatus to use a kite principle.  Of course if someone wants to re-define the word "kite" to cover virtually anything, then that person might "think differently".
Tides?  Maybe.  Currents?  Possible.  Waves?  Unlikely for kites.  Why?  No steady current in which to fly a kite.  I do note one team on the list: Team FLAPPER (Floating Lever and Piston Power ExtractoR) (Research Triangle Park, N.C.)

Waves are an oscillation more than a steady current.
If you have ever been out surfing, especially in big waves, you cannot help but marvel at the immense power.  Each wave is like a freight train falling over sideways.  KaBoom!  Best to avoid the impact zone, or burrow way the heck underwater, as fast as you can.  Then again, most days have smaller waves.

For all the years I've been hearing about the urge to develop such wave energy systems, which usually seem pretty straightforward in operative principles, I have yet to see one that works well enough to get beyond the "press-release" or "prototype" stage.  Is anyone aware of any wave-power system operating today?  We had that recent well-publicized wave-apparatus in the Mediterranean near Gibraltar, if memory serves.  I wonder how that one is doing?  Barnacles anyone?  :)

Subject: Re: Sharp Intermeshing VAWT; Sharp VAWT with Flyball Governor; Sharp
I don't think Pierre "overlooked" anything, but rather was using the term "horizontal-axis" to include "near-horizontal" configurations, using (normal) propellers of the type seen on "horizontal-axis" (normal) turbines, many of which operate at a (this is normal) significant angle from horizontal, to avoid tower-strikes. 

For example, the 10-KW turbine here sits at about a 10-degree tilt-back angle.  You would never notice the tilt unless you were looking for it.  There's nothing requiring a "horizontal-axis" turbine to be exactly horizontal. 

And no, for someone to maintain an exactly horizontal projection, relying on the Earth's curvature to eventually achieve altitude, would definitely be taking the term "horizontal" too literally.  I'd like to see the proposal trying to rationalize that approach.

Waves?  There are shore-breaking waves with their return waves. There are wind waves in mid-sea. And long-wavelength waves caused by moon gravity. There are waves caused by earthquakes. And waves caused by powered or wind-powered hulls.  Wings tethered in any of the above or other water waves are game for setting in motion tethered wings where the kite principle works. There is a huge sport and recreation industry already in place where the kite principle operates to give desired good works (results).   We have in forum already a discussion moment over mounting electric turbines on the hulls of surfboards; one may explore adding the same to tethered wings, wakeboards, and the like for making electricity for use onboard the wing or about the wing rider (say for conspicutiy lighting or/and warming; say on long river tidal bores). .

The "oblique" axis turbines have already some forum discussion. The offset angle (say, alpha) for a  rotor relative to the downwind line generally horizontal or parallel to the wind flow (distinctions can be made as Doug mentioned; that is true horizon challenges versus stream-flow lines which might even be vertical as when an AWES is set to rotate is sweeping disk perpendicular to the ambient fluid flow).   The alpha angle plays large in the text in Doug's multirotor patents.   In many kited wings and kite-system-held rotors, the angle of the wing or rotor relative to the ambient flow will show up as an important analytic parameter; rigging and bridling face the angle set challenges.  When needed in specifications or experiments, the angles may be carefully noted. When wind is upslope or downslope then such wind is not in plane with the local horizon.

Subject: Re: Wave-Energy and Kite Principle
Take a fixed point on seafloor; tether a wing set to Earth at that fixed point. Have a kytoon set high in the water but below the water surface; let the mid-sea waves interact and deflect the wing set; use the deflection of the kited wing set to generate good works, perhaps electricity in groundgen or flygen (or both) draw. Did any of the 97 teams use such kiting principle to obtain electricity? The wing set deflections could be the result of design for high average production within the local current and wave environment.  The current in mid-sea will have its fairly constant rate; the waves in that environment would add energy-generation opportunities above that which the local current provided. That the wave undulates would provide opportunities for changes that could drive generators in the wing set or in the tether set or in the anchor set.

Earlier today, in gusty East Austin* winds, kPower successfully combined a 2.0m2 Pansh power kite, kPower PTO, and k-Power crosswind arch-loop, for fast powerful load-motion (~30mph) of the arch-loop. Close manual piloting enabled high capacity-factor cycling, with only brief pauses turning around at the kite window edge. Up-coming test sessions will use bigger kites, add rigging refinements and groundgen integrations, and do video documentation.

This kite and PTO dates to kFarm 2012, but never before rigged to haul a crosswind loop. Also in 2012, kFarm had tested wire rope crosswind cableways of a cruder design, with up to a 32m2 NPW, confirming raw power and workability.The long delay in testing this natural combo is due to so many exciting aspects of kites to explore, that the broad R&D pace is glacial, or like watching grass grow. We are marking ten years of the AWES Forum, and  cumulative progress in AWE has been fantastic on many fronts. Ten years ago no one knew how to take a stock power kite and tap it for mechanical work with just a simple pulley-and-string PTO affair. Now we know.

Sadly noting that HAWPcon09 is no longer accounted by self-absorbed AWEC conference organizers as the first major AWE conference, who now only choose to recall AWEC2010, which in open-AWE was reckoned as the first "hijacked conference", and only AWC2011 was a brief glasnost, under Wubbo's generous influence. AWEIA and its values in particular have been studiously ignored or even banned at AWEC conferences, while the favored parties get to party.

Fort Felker is an AWEC2017 keynote speaker who became very elusive when GoogleX lured him from US DOE/NREL a couple of years ago, but he may make major new Makani disclosures, like the M600's measured power efficiency or crash event analysis. There is a poor public documentation trail of AWEC's conference proceedings, apparently from lack of insider motivation, not lack of media capability.
 Its hoped that AWE conferences will someday recoup the magic of Hawpcon09 and AWEC2011, once AWEC's malign legacy has spent itself.

Recalling that Makani/Joby was lead founder of AWEC, a US CA C4 industry association, but Makani bailed out of AWEC around 2013, as it began to fail, and it passed hands to EU. The C4 probably was killed due to legal liability, since a real industry association has to follow standards of transparency and equity under US IRS non-profit law. Now that the legal burden has been shed, we see Makani coming right back in into the AWEC conference track, for its third keynote lap. Fort comes out of Stanford, same many Makani-Joby kahunas.

Fortunately, AWE is a wide open knowledge quest, and unlimited capital and public mindshare are not enough. Disclaimer: I was inside early Makani and AWEC, and know most of the early top players personally, and Fort, via NREL/NWTC, so my opinions are somewhat personal. If only the leaders had resolutely put public AWE knowledge over venture-capitalism, I would be praising AWEC. Secretive AWE players are more entrenched and numerous than ever. The small experimenter remains in play as well. Lets see which ethos wins the tech race.

Even as the pay-to-play AWEC (AWE Consortium) itself somehow lapsed, its AWEC conference brand lives on within a tiny EU insider group. Sadly noting that HAWPcon09 is no longer accounted by self-absorbed AWEC conference organizers as the first major AWE conference, who now only choose to recall AWEC2010, which in open-AWE was reckoned as the first "hijacked conference", and only AWC2011 was a brief glasnost, under Wubbo's generous influence. AWEIA and its values in particular have been studiously ignored or even banned at AWEC conferences, while the favored parties get to party.

Fort Felker is an AWEC2017 keynote speaker who became very elusive when GoogleX lured him from US DOE/NREL a couple of years ago, but he may make major new Makani disclosures, like the M600's measured power efficiency or crash event analysis. There is a poor public documentation trail of AWEC's conference proceedings, apparently from lack of insider motivation, not lack of media capability.
 Its hoped that AWE conferences will someday recoup the magic of Hawpcon09 and AWEC2011, once AWEC's malign legacy has spent itself.


"Schedule

The scientific program of the conference will last from 9:00 - 18:00 each day and consist of invited keynote and plenary talks, parallel talks, and poster sessions.

Invited keynote speakers (confirmed):

Dr. Fort Felker, General Manager, Makani, X, California

Dr. Fort F. Felker is the General Director of the X project Makani since May 2015. He was previously at the National Wind Technology Center of the US National Renewable Energy Laboratory (NREL). Dr. Felker is a Co-Founder of Winglet Technology, LLC in June 2001 and served as its Vice-President of Engineering and holds a patent for elliptical winglet design. He has 30 years of aeronautical and mechanical engineering research and technology development expertise, including work at Kenetec Windpower, NASA Ames Research Center, the U.S. Army Research and Technology Labs. He has a master's of science and a doctoral degree in mechanical engineering from Stanford University. 

Prof. Henrik Stiesdal, DTU Wind, Denmark
Prof. Stiesdal is an affiliate professor at DTU Wind, the Technical University of Denmark's Department of Wind Energy. Among his many achievements, Prof. Stiesdal designed one of the first wind turbines representing the so-called "Danish concept", a design that was licensed to Vestas A/S. He has worked for two Danish wind turbine manufacturers: for Vestas, as a project manager betwee 1983 and 1987, and for Bonus Energy A/S as a development specialist and technical manager. Prof. Stiesdal further served as Chief Technology Officer of Bonus Energy between 2000 and 2004, the year when Bonus was acquired by Siemens. Stiesdal became the Chief Technology Officer of Siemens Wind Power and remained in this position until the end of 2014, when he retired."

In my humble opinion, the first High Altitude Wind Energy Conference in Chico - Oroville, was the ONLY "real" airborne wind energy conference.  The "conferences" ever since then have been boring, robotic, bland, predictable, conveying little or no new information - basically a waste of time and money.  The FIRST conference introduced what was a NEW CONCEPT (to most people) and many excited afficionados got together and discussed a myriad of possibilities openly.

After that, it has really been nothing but more and more "me-too-ism".  (Look, we are also trying kite-reeling, and we have pix!)  I don't think any number of people standing up in front a group just saying "yah yah yah we are flying a kite in a circle now after 5 years" or whatever, makes any difference at all. 

I think every day that goes by with people thinking that more "talk" is the answer are not seeing what is right there in front of them.  At this point I think either someone is going to do it, or not, and further "conferences" are irrelevant.  Oh well, my opinion, obviously not everyone agrees. 

But I think it is really out of a lack of progress and actually, sheer boredom, that people even want to organize such conferences.  You'd think someone that close to the edge of an energy breakthrough would be too busy getting it actually working to want to waste any more time just talking about it, ESPECIALLY to a group of (potential) competitors.

Buoys of different shapes are water paravanes (energy kites using water as media); the shapes of the wings and tethers and anchors vary. AWES may use more than one media in one system among, say, soil, water, air. 

Here is a video from one company Carnegie Clean Energy  whose kited wing is a LTW wing (lighter than water).

HAWE IDEA DEVELOPMENT

Here is a summary of my thought processes in the development of a novel HAWE system:

   Combine multiple coaxial turbines with a cable drive.

   Select one of three options for transferring axial torque to the cable drive.

   Enable orientation of turbines into the wind by means of universal joints.

   Use 2 parallel counter-rotating rows of turbines to neutralize lateral torque.

   Use 2 parallel cable drive systems to aid in kite steering, stability and splitting the load.

   Use rotating cage, independent of the pulley to retract the cable drive.

   Use multiple rows of lifter kites, linked together.  Use diagonal stays to stabilize the system.

   Launch lifter kites individually and link in the air.

   Use LTA tubes in lifter kites to facilitate launching and stay aloft in low wind conditions.

   Use LTA tubes to assist in launching. Tubes are retracted after initial launching.

   Use hot air in tubes to assist in launching. Tubes are retracted after initial launching.

   Launch the complete array of kites simultaneously with automatic release.

   Revert to a single cable drive for each kite since diagonal stays make the system stable.

   Combine the controls for the lifter kites and the diagonal stays at a single station.

   ?

Each time I think I have run out of ideas, I come up with a new one.

A pumping krypton is a close analogue to many of these wave gens, but waves are the inherent pumping basis rather than stimulated pumping in flow. The kite principle begins to appear in any tethered force case, if not in full-blown iconic kite wing form.

Where sky kite design might add great value to wave energy harvesting is that slightly buoyant fabric surface might out-pump a purely buoyant equivalent mass, and/or cost a lot less. Such an approach might resemble jellyfish pumping action rather than just a float bobbing.

Correction: "Kytoon" was intended spelling. "Krypton" seems to have been a machine spell-checking error. Thanks to Joe for spotting the error.
