Subject: Use of Test Dummies for developing Safe Aerotecture
Human safety is the true top issue in AWE R&D, as our machines begin to process monster power. Too many people lost their life developing HGs. Aerotecture, in particular, needs to be particularly safe, given its intended output of high passenger-hours.

Recent kPower aerotecture experiments made do with simple dummie loads like sandbags and luggage. A more realistic test would be to use humanoid test dummies. Industrial dummies are expensive and over-specialized, and we don't need to precisely measure the devastating effect of falling from a great height. Rescue-dummies are far simpler humanoids that approximate the mass and handling of an unconscious victim. Many rescue teams make DIY dummies by stuffing a coverall suit with "stick skeletons" and soft weights (sand or water) wrapped in rags like a mummy, to save money. Some DIY dummies have even reproduced human bone-breaking realistically (wood dowels, bamboo, or plastic pipe)

That is the stage we are at here in Texas, at the Encampment. Last year we flew a crate of small sandbags under Mothra. Now the plan is fly as best a dummy we can, and even make a small collection of dummies, to validate over time human safety under a modern kite system. We can perturb and stress the system at an accelerated pace, to identify and resolve every failure mode discovered. Expert human test-pilots would only ascend once the dummy has survived multiple long sessions in the same conditions without any mishap or near-mishap. The test-pilots would then eventually validate human safety for a wider passenger experience.

Current design-load safety-factors is 8-1, with minimum triple-redundant fall-safety systems (surface fall-tent, body harness and safety line, emergency descent rappel, payload apex chute, payload fall-net stage, multiple lifter units, etc.). Planned tests use a variety of kites and rigs to validate various details, to lead to an airborne village made of Tentsile units on a triangular loadpath net, under a larger Mothra(2).

Subject: USAF AWE Implimentation Study
AWE is being militarized behind the scenes without societal debate. Wayne German, in particular has openly warned about militarization risks, and most of us would like to see AWE only used for peaceful purposes, rather than a global arms-race. The AWE Military Moratorium subject is taboo at AWEC conferences.

The book linked below is about how the US Air Force might adopt AWE as a basis for future dominance. It would be interesting if the author carefully considered the arms-race risk, and other downsides. Paradoxically, the USAF might be better off if military AWE does not gain global mindshare. Military AWE is a Pandora's Box. Perhaps JoeF can get a press-copy to review-

Subject: Re: Low-Solidity of Mothra-Rotor Hybrids

Well, hats off to you for the high number of tarps.  I am sorry if I mischaracterized it as 100% solidity - just an old windy's reaction to something so new and advanced I could not comprehend it properly.
That really is a lot of tarps.
I think you have convinced me now.
I'm beginning to share your vision:
Millions of tarps above NYC, in a giant array where people can live, hang and swing among the tarps, shuttling about in the sky along rope railways, endless energy being supplied by generators reeling in and out below, pulled up and down by pulsating bands of tarps, dedicated rock-star pilots, volunteering to keep it all aloft at any given moment, for the sheer glory...  Sorry to have doubted you.

:)

Well it would make a good movie anyway...

Maybe you should try the movie angle,

kind of like "Water World"


Anyway, I just hope the wind doesn't suddenly switch direction or stop.

But wait - the wind is always stopping and starting, always changing direction.  Sometimes several times a minute!  Oh well.


Wait - that could be the plot of the movie.  The engineers were paid by global warming people, so they rushed the job, and forgot to include what would happen when the wind stopped.  The system is up and running with great fanfare, yet the weatherman on TV is calling for calm.

Forget about the system, what about the city?  Where is Bruce Willis when you need him?

Subject: Re: Looping wing under a pilot kite
Reminds me quite a bit of Figs. 81-89 of U.S. Patent 6616402 Serpentine Wind Turbine, except you have removed all the other blades except one.
Can I let you in on a secret discovered a couple thousand years ago?  A rotating sail, or kite, works well when counterbalanced against at least one other rotating sail, or kite.
The assembly is then called a rotor, and the sail, or kite, is called a blade.
The advantage is you don't have to steer a single blade in a circle - the circular path becomes automatic.  Automatic steering 3000 years ago - who knew?  Think of square-dancing: "Swing yer partner, round & round!"

I know, I know, Makani has gotten a lot of mileage showing the world how it can FORCE a SINGLE kite to go in a circle, (after years of forced figure-8's, while people like me wondered why they had not discovered the 3000-year-old and by-now standard circular path), or the equally-ancient concept of at least one more blade per rotor, to counterbalance the first... (One more newbie re-invention - the old one-bladed turbine concept - a Professor Crackpot favorite, but only a very advanced Professor Crackpot usually promotes one-bladed rotors, like the original Skypower prototype from Australia, which, when I first saw it a decade or so ago I thought "Why use a 1-bladed rotor when it just needs a counterweight anyway?" - "Hey, let's add one questionable feature that ruins the whole thing!"
I remember when this beautiful girl flew in to visit me several years ago.  On the flight, she sketched out a wind turbine where a row of rotors was arrayed along each blade of a large wind turbine, a bunch of little generators replacing the main generator.  That was her first wind energy idea with no experience.  Her idea was not new then, and it is not 100% new with Makani doing it.  Just that Makani used just a single blade root.  "No it's a blade tip!"  Oh, OK if it makes them feel better.  How 'bout a blade midsection?  What is the TSR?  That would tell you if it is a tip, midsection, or root.  Wow, come to think of it, I have not heard anything about them in a long time.  Sometimes big companies buy up little ones just to make sure they don't miss out on something, but then lose interest.
Here's my question:
Why beat around the bush?
Why not build the WHOLE SuperTurbine(R), rather forcing one blade to travel in a circle, with no way to extract the power?  I mean, it's cute, but where are all the rest of the blades?  You can put up 80 tarps, but only 1 blade?  Let me know if you need some guidance... The reason I brought a SuperTurbine(R) to the first AWE conference was to show people how it's done, save them a lot of headscratching, trial and error, reinventing the wheel, and so forth.  I know, sometimes you can hand people an idea on a silver platter but they aren't  ready for it yet.  The nice thing is it has quite a bit of research and some data to back up the concept, and it has wide patent protection.  Maboomba!

Subject: Re: Electron Wind Generator
Electrostatic Wind Turbine have been an April Fools joke in wind energy.
These jokers' websites always look the same.
All their promises will turn out to be false.
Non-potable water - wow, I wanna see how much wind goes thru those panels after mineral buildup.
The panels themselves look to me like they will take 59% of the wind's energy, just by their physical impediment to the windflow!  That's before you extract any power at all.
The key to wind energy's economic advantage is you only need to cover a small fraction of the swept area with blade. 
I'm all in favor of such schemes which we wind people have brainstormed over more then once, but, like I say, the highest use we've found so far, is the concept makes for a great joke.
Wishful thinking.

Subject: Re: Looping wing under a pilot kite
Doug,

The incentive to develop a looping wing under a pilot kite is so that pure tensile force passively drives AWE pumping. This bypasses the major flaw of the SuperTurbine, to not scale to high altitudes, due to cubic mass scaling-law and high negative lift of its driveshaft. 2009 seems to represent your nearing the SuperTurbine scaling-law barrier, with only a small unit achieved flying at a very low angle.

Of course, Nature invented the single-bladed turbine, in the form of the maple-seed, so any a-priori argument that turbines must have more than one blade is nonsense. The kPower SpinWing is not even strictly a one-blade turbine, as it uses two wings; the upper wing, while providing stable overall flight, still acts against the other wing, flying a smaller pattern. The harder the upper kite works, the more power available at the base, with less damping loss.

Putting more wings radially into the mix horribly complicates launching and power tapping. As it is, the SpinWing under a Pilot-Lifter will stop looping in calm and land and relaunch in sequence, in good order. Power tapping by a kPower PTO is simple. Reciprocating power is not so impractical or unpromising as you insist: your own car contradicts the "rotary-only" thesis.

A megascale arch naturally supports an array of WECS units. SpinWings would be arrayed crosswind like any other scale-unit crosswind. The minimal count foreseen for a smaller arch would be two opposed spinwings, for balanced motion. The current single-cell version is not an arch.

Mass and gravity help looping foils pump. The larger a parafoil, the more its neutral buoyant internal air mass acts to assist overall steady rotation. But as the looper dives past "7 o'clock", the maximum mass-velocity is created by both kite-mass gravity-boost and DS boost. At the weak top of the loop, and in the dive, the PTO recoils easily (by a weak fast-retract bungee). This is a superior more-crosswind cycle compared to downwind reeling schemes.

A next phase of testing will validate stacks of spinwings along the single helical loadpath, but this is still no closer to an airborne driveshaft scheme, with radially symmetric wings. Its up to you to validate that path, but you have missed the time-frame you impose on others,

Subject: Re: Looping wing under a pilot kite
Sounds like another case of "All Roads Lead To SuperTurbine(R)" to me...
Add the rest of the blades.  Use the rotation to drive a generator.  Then you have a SuperTurbine(R).  Sure, single-bladed rotors work.  A perennial Crackpot favorite as a matter of fact.  None has succeeded.  It wouldn't start out as my first choice, but hey, if it works, it works.  It's still a SuperTurbine, as delineated in U.S. 6616402, which covers and illustrates single bladed rotors (Figs. 12, 13).  Reciprocating motion in wind energy?  OK Dave S., whatever you say... :) That would be a giant step backwards, and it provides power only for part of a cycle.  That is great for matching the intermittent cycle of a piston, but a poor match for the NON-pulsating wind.  It has been found that uninterrupted power output works best.

The concept of "all roads lead to SuperTurbine(R) is something like this:

1) In the present case, it is obvious that you describe what I disclosed in that first patent, minus all blades except 1, and minus the generator.
Add more blades and a generator at the ground and you have a SuperTurbine(R).  Forget your clap-trap about a driveshaft not being able to carry the torque:
a) It is simply incorrect that a driveshaft can't handle that much torque;
b) these embodiments do not all use a solid central driveshaft, but instead transmit the torque downward by torque transmission lines that rotate with the whole assembly, as you can see in the patent.

2) If you are Makani, after the first couple years of figure-8's, they finally adopted two (2) of the main features I keep telling you all overcome typical newbie missteps:  a) They hardened the wing from cloth to a solid surface, and b) they scrapped the figure-8 in favor of a circle. 
So
a) If they get a successful product, should they NOT add more layers above? 
b) If they see they have hundreds of small generators on the wings, might they not realize the power is better extracted at ground level using a single generator, from the overall rotation?  Would this not be more efficient i) aerodynamically,  ii) electrically, and iii) economically?
c) If they have a hard wing rotating, would it not make sense to use an opposing blade as practiced for 3000 years, to balance against the first blade? 
d) Would this not overcome the power lost to steering the single wing in a circle?

It feels funny having to point this stuff out.
Is everyone really that unaware?

OK Let's take the reeling in-and-out approach:
1) using kites - well that recovery cycle is inefficient, and the downwind travel bleeds away otherwise usable power.  Eventually they will find that rotation of their kites is best, and stacking multiplies power, the heavy generator is best left at the lower end, and they will have a SuperTurbine(R).

2) For those using propellers,
a) they lose power if they are allowed to travel downwind, so holding their ground is best. 
b) Recovery cycles waste otherwise productive time, using power instead of making power.
c) The circular path is best accomplished using opposing blades, stack them for multiplied output, and you have one more SuperTurbine(R).

As for SkyWindPower - I don't know what's holding them back.  Don't really see any flaws in the concept, rather I see unlimited possibilities. 
Successful versions might be stacked to multiply output, forming a SuperTurbine(R). 

Have a winderful day!

Subject: Answering Doug on wind-variability (review)

Doug: "I just hope the wind doesn't suddenly switch direction or stop. But wait - the wind is always stopping and starting, always changing direction.  Sometimes several times a minute!"

True, which is why KiteLab Group has designed, built, and tested so many specific ideas to cope with wind-variability. The wind-variability problem is not as bad as you think, and research progress continues.
Kite arches inherently tolerate large wind shifts by merely leaning downwind. Megascale (km scale) AWES will hardly notice common small-scale wind turbulence. Larger scale turbulence is rarer, and modern forecasting and sensing allow for timely avoidance. Normal changes in prevailing wind direction occur on a scale of hours or days, so even manual anchor-belay methods work well (We can even just land Mothra1 in veering high-wind, roll-up the wings, rotate-to-new-crosswind, unroll, and relaunch; in under five minutes).
As rotation methods finally become unwieldy at double-digit km scales, we have designed and tested small-scale symmetrical "kite domes" or large-array kixels that merely tilt downwind to lift in any wind direction, without rotating. No scaling barrier seems to forbid meshes of such tilting wing surfaces to extend horizontally to a planetary-scale extent, and be reverse-pumped in zonal calms from surrounding meshes.

If such amazing technical possibilities are beyond your imagining, go ahead and laugh the first laugh.

Doug,

Its not been claimed that driveshafts cannot handle torque, its claimed that its impossible to build an airborne drive-shaft light and cheap enough to compete with rope-driving beyond tower-altitudes. 

Single bladed turbines are more common than your imaginary high-altitude driveshafts. Note the looping-kite under a pilot-lifter is really two wings, and does not need a drive-shaft to pump a groundgen, just "kiteline",

No driveshaft, no SuperTurbine,

Subject: Lets put some wind into the sail! NOW

I was searching around for a good site for kite and airborne wind power discussions and at last I have been kindly directed here by Joe Faust from a LinkedIn Group. Cheers Joe – like the site as well very handy!

Anyway – I have been for a short time involved with a project run by my company that looks somewhat like the Delft Kite, my area of interest is developing a recyclable tether. I have also been in touch with some other startups as well. So I would describe myself as semi ignorant but highly enthusiastic. I like everyone else, also have several ideas I would love to develop, but that can wait.

I like to be practical, pragmatic and scientific in my approach to technology developments. There are clearly surmountable obstacles on our journey to efficient airborne wind generation – but surmountable they are and our field of energy generation will eventually make horizontal axis wind turbines into ugly obsolete windmills – perhaps they will make useful towers to launch giant kites!

Anyway – enough of my distaste for HAWT.

My point is that the public know almost nothing about the work being done by the airborne power generation industry. We have no profile to speak of. Every few months a paper or magazine makes some mention of one of the current projects and then everything goes quiet.

For start we need an International Symposium on Airborne Wind Power. I run several Symposiums a year – they are not difficult to arrange!

We need serious profile to drive out the serious investors from their burrows. The industry is far too much a hotch potch of individuals with ideas and claims. How can an outsider make out what is really going on – where are the realistic projects that have a chance of success, who do they contact, where are the numbers on CAPEX and OPEX for these systems along with unit power costs and land / sea area and airspace requirements, along with environmental impact studies. Will they kill birds and bats like Wind Turbines do?

Perhaps it is too much to expect a bunch of competitive wind geeks (It’s OK – I’m one too and proud of it) to get together and put something out there that is really useful to new investors and to the general public.

So – what do you think – can you experts and developers of new businesses and new ideas get together for long enough to work out how to build the community and communicate?

The sooner we do this then the sooner the industry will get the investment it needs to fast track some developments – I have been waiting for several years for results but they are few and far between! We need proof of success just as soon as you possibly can, then we won’t have to have our countries covered in soon to be obsolete windmills!

Hi Mark,
Glad to hear your positive take on AWE development.

With you on the need to coordinate.

We can avoid catch 22 problem, getting the detail necessary for standard broad spectrum investors without having had the investment to generate these numbers...

The symbiotic initial investment spark may come from the AWE value proposition of global & ecological health benefits derived from efficient generation.... Development funding from insurance and early stage pension pots looking to offset the many published future risks.

So e.g. where these investments go into hydrocarbon research they could be shifted to AWE.
Christiana Figueres Executive Secretary of the United Nations Framework Convention on Climate Change (UNFCCC) seems to agree

Alternatively we could describe our own AWE specific research investments fund.

By developing a coordinated group task list each with assigned proportion of total group value.
CAPEX becomes the expenditure on approved job scopes derived from our cooperative IP pool development needs
OPEX IP pool marketing
Both work value and investments value can be assessed together under total scheme value.
Thereby, Investors are inspired to keep developers motivated and productive.

Hello Mark,

Welcome to AWES. Probably you have not yet had time to plough through
all the old messages or you would have come across
http://www.awec2013.de/

One of the problems we have on this group is that there are almost as
many ideas on how to do AWE as there are members. Predicting the cost of
energy from a device that lives only in a person's imagination is very
difficult. My belief is that a number of different concepts could each
find niche markets where they are economically viable.

It would be great if we could attract more funding to AWE. I think the
way to do is to take a long-term approach. The fundamentals of AWE make
a lot of sense and the total market could be trillions. Funders should
initially support numerous teams all over the world with relatively tiny
amounts. Those who can meet their objectives with small pots of money
get more until over a dozen or so micro-funding rounds the winners start
to emerge.

Robert.
